+ *\r
+ * When the USI counter overflows, a byte has been transferred.\n\r
+ * The USIDR contents are stored and flags are updated.\r
+ *\r
+ * The protocol is quite simple and has three sequential states: command,\r
+ * address and data.\r
+ * (Keep in mind that the Master is in charge of data clocking, which means\r
+ * there is a one byte "delay" from when the Slave puts something to SPI till\r
+ * the Master can read it.)\r
+ *\r
+ * 1. If a non-zero byte is received in the command state, the ISR will\r
+ * store the commands to the SPI struct (read/write, EEPROM/SRAM, number of\r
+ * bytes). To signal that the command was received, 0xCC is put to the SPI bus.\r
+ * If a zero byte (0x00) is received in the command state, it is simply ignored\r
+ * because it is an invalid command.\r
+ *\r
+ * 2. When a byte is received in the address state, it is stored to the SPI\r
+ * struct. To signal that the address was received, 0xBB is put to SPI bus.\r
+ * \r
+ * 3. In the data state, variables are read/written "from back to front" until\r
+ * the byte counter reaches zero. Since the Master is in charge of the data\r
+ * clocking, the Slave will go to command state before the last byte is\r
+ * transferred during reading. This means that the Master should send an \r
+ * invalid command when getting each byte, ie 0x00.\r
+ *\r
+ * If the time between two transfers is 1 second or more, the Slave\r
+ * automatically reverts to command state.\r
+ *\r
+ * \note Battery charging is not automatically halted during SPI communication.\r
+ * This means that the current charge state (current and voltage) will\r
+ * remain constant during heavy and prolonged serial traffic.\r

+ * the source have to be modified.\n\r
+ * \n\r
+ * To make project on IAR EWAVR:\n\r
+ * Add the .c files to project (ADC.c, battery.c, main.c, menu.c,\r
+ * OWI.c, PWM.c, time.c and USI.c). Add either LIIONcharge.c or NIMHcharge.c,\r
+ * and update LIIONspecs.h or NIMHspecs.h, and battery.h with the appropriate\r
+ * battery data if needed.\n\r
+ * \n\r
+ * Use device --cpu=tiny861, enable bit definitions in I/O include files,\r
+ * optimization low for debug target and high for release, output format: ubrof8\r
+ * for Debug and intel_extended for Release. \n\r
+ *\r
+ * \section deviceinfo Device Info\r
+ * This application is based on the ATtiny 861, but it is possible to migrate \r
+ * the design to other AVR microcontrollers, such as pin-compatible devices\r
+ * ATtiny 261/461. Low pin count devices such as ATtiny 25/45/85 may also be\r

+ 53 /*! \brief USI Counter Overflow Interrupt Service Routine\r
+ 54 *\r
+ 55 * When the USI counter overflows, a byte has been transferred.\n\r
+ 56 * The USIDR contents are stored and flags are updated.\r
+ 57 *\r
+ 58 * The protocol is quite simple and has three sequential states: command,\r
+ 59 * address and data.\r
+ 60 * (Keep in mind that the Master is in charge of data clocking, which means\r
+ 61 * there is a one byte "delay" from when the Slave puts something to SPI till\r
+ 62 * the Master can read it.)\r
+ 63 *\r
+ 64 * 1. If a non-zero byte is received in the command state, the ISR will\r
+ 65 * store the commands to the SPI struct (read/write, EEPROM/SRAM, number of\r
+ 66 * bytes). To signal that the command was received, 0xCC is put to the SPI bus.\r
+ 67 * If a zero byte (0x00) is received in the command state, it is simply ignored\r
+ 68 * because it is an invalid command.\r
+ 69 *\r
+ 70 * 2. When a byte is received in the address state, it is stored to the SPI\r
+ 71 * struct. To signal that the address was received, 0xBB is put to SPI bus.\r
+ 72 * \r
+ 73 * 3. In the data state, variables are read/written "from back to front" until\r
+ 74 * the byte counter reaches zero. Since the Master is in charge of the data\r
+ 75 * clocking, the Slave will go to command state before the last byte is\r
+ 76 * transferred during reading. This means that the Master should send an \r
+ 77 * invalid command when getting each byte, ie 0x00.\r
+ 78 *\r
+ 79 * If the time between two transfers is 1 second or more, the Slave\r
+ 80 * automatically reverts to command state.\r
+ 81 *\r
+ 82 * \note Battery charging is not automatically halted during SPI communication.\r
+ 83 * This means that the current charge state (current and voltage) will\r
+ 84 * remain constant during heavy and prolonged serial traffic.\r
+ 85 *\r
+ 86 * \todo Variable writing not implemented yet.\r
+ 87 * \todo EEPROM/SRAM flag doesn't really do anything with this implementation.\r

+// 54 *\r
+// 55 * When the USI counter overflows, a byte has been transferred.\n\r
+// 56 * The USIDR contents are stored and flags are updated.\r
+// 57 *\r
+// 58 * The protocol is quite simple and has three sequential states: command,\r
+// 59 * address and data.\r
+// 60 * (Keep in mind that the Master is in charge of data clocking, which means\r
+// 61 * there is a one byte "delay" from when the Slave puts something to SPI till\r
+// 62 * the Master can read it.)\r
+// 63 *\r
+// 64 * 1. If a non-zero byte is received in the command state, the ISR will\r
+// 65 * store the commands to the SPI struct (read/write, EEPROM/SRAM, number of\r
+// 66 * bytes). To signal that the command was received, 0xCC is put to the SPI bus.\r
+// 67 * If a zero byte (0x00) is received in the command state, it is simply ignored\r
+// 68 * because it is an invalid command.\r
+// 69 *\r
+// 70 * 2. When a byte is received in the address state, it is stored to the SPI\r
+// 71 * struct. To signal that the address was received, 0xBB is put to SPI bus.\r
+// 72 * \r
+// 73 * 3. In the data state, variables are read/written "from back to front" until\r
+// 74 * the byte counter reaches zero. Since the Master is in charge of the data\r
+// 75 * clocking, the Slave will go to command state before the last byte is\r
+// 76 * transferred during reading. This means that the Master should send an \r
+// 77 * invalid command when getting each byte, ie 0x00.\r
+// 78 *\r
+// 79 * If the time between two transfers is 1 second or more, the Slave\r
+// 80 * automatically reverts to command state.\r
+// 81 *\r
+// 82 * \note Battery charging is not automatically halted during SPI communication.\r
+// 83 * This means that the current charge state (current and voltage) will\r
+// 84 * remain constant during heavy and prolonged serial traffic.\r
+// 85 *\r
+// 86 * \todo Variable writing not implemented yet.\r
+// 87 * \todo EEPROM/SRAM flag doesn't really do anything with this implementation.\r

+ 139 *\r
+ 140 * \section compinfo Compilation Info\r
+ 141 * This software was compiled with IAR Embedded Workbench, 4.30. To use GCC \r
+ 142 * the source have to be modified.\n\r
+ 143 * \n\r
+ 144 * To make project on IAR EWAVR:\n\r
+ 145 * Add the .c files to project (ADC.c, battery.c, main.c, menu.c,\r
+ 146 * OWI.c, PWM.c, time.c and USI.c). Add either LIIONcharge.c or NIMHcharge.c,\r
+ 147 * and update LIIONspecs.h or NIMHspecs.h, and battery.h with the appropriate\r
+ 148 * battery data if needed.\n\r
+ 149 * \n\r
+ 150 * Use device --cpu=tiny861, enable bit definitions in I/O include files,\r
+ 151 * optimization low for debug target and high for release, output format: ubrof8\r
+ 152 * for Debug and intel_extended for Release. \n\r
+ 153 *\r
+ 154 * \section deviceinfo Device Info\r
+ 155 * This application is based on the ATtiny 861, but it is possible to migrate \r
+ 156 * the design to other AVR microcontrollers, such as pin-compatible devices\r
+ 157 * ATtiny 261/461. Low pin count devices such as ATtiny 25/45/85 may also be\r
+ 158 * used, but with reduced functionality.\r

+ 53 /*! \brief USI Counter Overflow Interrupt Service Routine\r
+ 54 *\r
+ 55 * When the USI counter overflows, a byte has been transferred.\n\r
+ 56 * The USIDR contents are stored and flags are updated.\r
+ 57 *\r
+ 58 * The protocol is quite simple and has three sequential states: command,\r
+ 59 * address and data.\r
+ 60 * (Keep in mind that the Master is in charge of data clocking, which means\r
+ 61 * there is a one byte "delay" from when the Slave puts something to SPI till\r
+ 62 * the Master can read it.)\r
+ 63 *\r
+ 64 * 1. If a non-zero byte is received in the command state, the ISR will\r
+ 65 * store the commands to the SPI struct (read/write, EEPROM/SRAM, number of\r
+ 66 * bytes). To signal that the command was received, 0xCC is put to the SPI bus.\r
+ 67 * If a zero byte (0x00) is received in the command state, it is simply ignored\r
+ 68 * because it is an invalid command.\r
+ 69 *\r
+ 70 * 2. When a byte is received in the address state, it is stored to the SPI\r
+ 71 * struct. To signal that the address was received, 0xBB is put to SPI bus.\r
+ 72 * \r
+ 73 * 3. In the data state, variables are read/written "from back to front" until\r
+ 74 * the byte counter reaches zero. Since the Master is in charge of the data\r
+ 75 * clocking, the Slave will go to command state before the last byte is\r
+ 76 * transferred during reading. This means that the Master should send an \r
+ 77 * invalid command when getting each byte, ie 0x00.\r
+ 78 *\r
+ 79 * If the time between two transfers is 1 second or more, the Slave\r
+ 80 * automatically reverts to command state.\r
+ 81 *\r
+ 82 * \note Battery charging is not automatically halted during SPI communication.\r
+ 83 * This means that the current charge state (current and voltage) will\r
+ 84 * remain constant during heavy and prolonged serial traffic.\r
+ 85 *\r
+ 86 * \todo Variable writing not implemented yet.\r
+ 87 * \todo EEPROM/SRAM flag doesn't really do anything with this implementation.\r

+// 54 *\r
+// 55 * When the USI counter overflows, a byte has been transferred.\n\r
+// 56 * The USIDR contents are stored and flags are updated.\r
+// 57 *\r
+// 58 * The protocol is quite simple and has three sequential states: command,\r
+// 59 * address and data.\r
+// 60 * (Keep in mind that the Master is in charge of data clocking, which means\r
+// 61 * there is a one byte "delay" from when the Slave puts something to SPI till\r
+// 62 * the Master can read it.)\r
+// 63 *\r
+// 64 * 1. If a non-zero byte is received in the command state, the ISR will\r
+// 65 * store the commands to the SPI struct (read/write, EEPROM/SRAM, number of\r
+// 66 * bytes). To signal that the command was received, 0xCC is put to the SPI bus.\r
+// 67 * If a zero byte (0x00) is received in the command state, it is simply ignored\r
+// 68 * because it is an invalid command.\r
+// 69 *\r
+// 70 * 2. When a byte is received in the address state, it is stored to the SPI\r
+// 71 * struct. To signal that the address was received, 0xBB is put to SPI bus.\r
+// 72 * \r
+// 73 * 3. In the data state, variables are read/written "from back to front" until\r
+// 74 * the byte counter reaches zero. Since the Master is in charge of the data\r
+// 75 * clocking, the Slave will go to command state before the last byte is\r
+// 76 * transferred during reading. This means that the Master should send an \r
+// 77 * invalid command when getting each byte, ie 0x00.\r
+// 78 *\r
+// 79 * If the time between two transfers is 1 second or more, the Slave\r
+// 80 * automatically reverts to command state.\r
+// 81 *\r
+// 82 * \note Battery charging is not automatically halted during SPI communication.\r
+// 83 * This means that the current charge state (current and voltage) will\r
+// 84 * remain constant during heavy and prolonged serial traffic.\r
+// 85 *\r
+// 86 * \todo Variable writing not implemented yet.\r
+// 87 * \todo EEPROM/SRAM flag doesn't really do anything with this implementation.\r

+ 140 * \section compinfo Compilation Info\r
+ 141 * This software was compiled with IAR Embedded Workbench, 4.30. To use GCC \r
+ 142 * the source have to be modified.\n\r
+ 143 * \n\r
+ 144 * To make project on IAR EWAVR:\n\r
+ 145 * Add the .c files to project (ADC.c, battery.c, main.c, menu.c,\r
+ 146 * OWI.c, PWM.c, time.c and USI.c). Add either LIIONcharge.c or NIMHcharge.c,\r
+ 147 * and update LIIONspecs.h or NIMHspecs.h, and battery.h with the appropriate\r
+ 148 * battery data if needed.\n\r
+ 149 * \n\r
+ 150 * Use device --cpu=tiny861, enable bit definitions in I/O include files,\r
+ 151 * optimization low for debug target and high for release, output format: ubrof8\r
+ 152 * for Debug and intel_extended for Release. \n\r
+ 153 *\r
+ 154 * \section deviceinfo Device Info\r
+ 155 * This application is based on the ATtiny 861, but it is possible to migrate \r
+ 156 * the design to other AVR microcontrollers, such as pin-compatible devices\r
+ 157 * ATtiny 261/461. Low pin count devices such as ATtiny 25/45/85 may also be\r
+ 158 * used, but with reduced functionality.\r

+// 139 *\r
+// 140 * \section compinfo Compilation Info\r
+// 141 * This software was compiled with IAR Embedded Workbench, 4.30. To use GCC \r
+// 142 * the source have to be modified.\n\r
+// 143 * \n\r
+// 144 * To make project on IAR EWAVR:\n\r
+// 145 * Add the .c files to project (ADC.c, battery.c, main.c, menu.c,\r
+// 146 * OWI.c, PWM.c, time.c and USI.c). Add either LIIONcharge.c or NIMHcharge.c,\r
+// 147 * and update LIIONspecs.h or NIMHspecs.h, and battery.h with the appropriate\r
+// 148 * battery data if needed.\n\r
+// 149 * \n\r
+// 150 * Use device --cpu=tiny861, enable bit definitions in I/O include files,\r
+// 151 * optimization low for debug target and high for release, output format: ubrof8\r
+// 152 * for Debug and intel_extended for Release. \n\r
+// 153 *\r
+// 154 * \section deviceinfo Device Info\r
+// 155 * This application is based on the ATtiny 861, but it is possible to migrate \r
+// 156 * the design to other AVR microcontrollers, such as pin-compatible devices\r
+// 157 * ATtiny 261/461. Low pin count devices such as ATtiny 25/45/85 may also be\r
+// 158 * used, but with reduced functionality.\r

+/*! \brief USI Counter Overflow Interrupt Service Routine\r
+ *\r
+ * When the USI counter overflows, a byte has been transferred.\n\r
+ * The USIDR contents are stored and flags are updated.\r
+ *\r
+ * The protocol is quite simple and has three sequential states: command,\r
+ * address and data.\r
+ * (Keep in mind that the Master is in charge of data clocking, which means\r
+ * there is a one byte "delay" from when the Slave puts something to SPI till\r
+ * the Master can read it.)\r
+ *\r
+ * 1. If a non-zero byte is received in the command state, the ISR will\r
+ * store the commands to the SPI struct (read/write, EEPROM/SRAM, number of\r
+ * bytes). To signal that the command was received, 0xCC is put to the SPI bus.\r
+ * If a zero byte (0x00) is received in the command state, it is simply ignored\r
+ * because it is an invalid command.\r
+ *\r
+ * 2. When a byte is received in the address state, it is stored to the SPI\r
+ * struct. To signal that the address was received, 0xBB is put to SPI bus.\r
+ * \r
+ * 3. In the data state, variables are read/written "from back to front" until\r
+ * the byte counter reaches zero. Since the Master is in charge of the data\r
+ * clocking, the Slave will go to command state before the last byte is\r
+ * transferred during reading. This means that the Master should send an \r
+ * invalid command when getting each byte, ie 0x00.\r
+ *\r
+ * If the time between two transfers is 1 second or more, the Slave\r
+ * automatically reverts to command state.\r
+ *\r
+ * \note Battery charging is not automatically halted during SPI communication.\r
+ * This means that the current charge state (current and voltage) will\r
+ * remain constant during heavy and prolonged serial traffic.\r
+ *\r
+ * \todo Variable writing not implemented yet.\r
+ * \todo EEPROM/SRAM flag doesn't really do anything with this implementation.\r

+ * This documents the software for application note AVR458. This is a charger\r
+ * for Li-Ion batteries, based on ATAVRBC100.\r
+ *\r
+ * \section compinfo Compilation Info\r
+ * This software was compiled with IAR Embedded Workbench, 4.30. To use GCC \r
+ * the source have to be modified.\n\r
+ * \n\r
+ * To make project on IAR EWAVR:\n\r
+ * Add the .c files to project (ADC.c, battery.c, main.c, menu.c,\r
+ * OWI.c, PWM.c, time.c and USI.c). Add either LIIONcharge.c or NIMHcharge.c,\r
+ * and update LIIONspecs.h or NIMHspecs.h, and battery.h with the appropriate\r
+ * battery data if needed.\n\r
+ * \n\r
+ * Use device --cpu=tiny861, enable bit definitions in I/O include files,\r
+ * optimization low for debug target and high for release, output format: ubrof8\r
+ * for Debug and intel_extended for Release. \n\r
+ *\r
+ * \section deviceinfo Device Info\r
+ * This application is based on the ATtiny 861, but it is possible to migrate \r
+ * the design to other AVR microcontrollers, such as pin-compatible devices\r
+ * ATtiny 261/461. Low pin count devices such as ATtiny 25/45/85 may also be\r
+ * used, but with reduced functionality.\r
+ * \r
+ * Required fuse bit settings:\r
+ * <pre>\r
+ * FUSE BIT | SETTING\r
+ * ----------+--------------------\r
+ * CKDIV8 | 1 (unprogrammed)\r
+ * CKSEL3..0 | 0010 (internal osc)\r
+ * </pre>\r

+ *\r
+ * \par Rule 1\r
+ * <i>"All code shall conform to ISO 9899 standard C, with no extensions\r
+ * permitted."</i>\r
+ *\r
+ * Extensions are necessary because ISO C has no way of specifying that a\r
+ * function should be an interrupt service routine, or that we would like data\r
+ * members to be stored in f.ex. EEPROM.\r
+ *\r
+ *\r
+ * \par Rule 37\r
+ * <i>"Bitwise operations shall not be performed on signed integer types."</i>\r
+ *\r
+ * The compiler assumes all the 1's we shift around to make bitmasks are signed\r
+ * integers. Specifying them all to be (unsigned int), either directly or via a\r
+ * definition, would fix the rule violations, but also reduce code readability.\r
+ *\r
+ *\r
+ * \par Rule 45\r
+ * <i>"Type casting from any type to or from pointers shall not be used."</i>\r
+ *\r
+ * Assigning macro NULL, defined in stdlib.h, to a pointer causes this..\r

+@REM This bat file has been generated by the IAR Embeddded Workbench\r
+@REM C-SPY interactive debugger,as an aid to preparing a command\r
+@REM line for running the cspybat command line utility with the\r
+@REM appropriate settings.\r
+@REM\r
+@REM After making some adjustments to this file, you can launch cspybat\r
+@REM by typing the name of this file followed by the name of the debug\r
+@REM file (usually an ubrof file). Note that this file is generated\r
+@REM every time a new debug session is initialized, so you may want to\r
+@REM move or rename the file before making changes.\r
+@REM\r
+@REM Note: some command line arguments cannot be properly generated\r
+@REM by this process. Specifically, the plugin which is responsible\r
+@REM for the Terminal I/O window (and other C runtime functionality)\r
+@REM comes in a special version for cspybat, and the name of that\r
+@REM plugin dll is not known when generating this file. It resides in\r
+@REM the $TOOLKIT_DIR$\bin folder and is usually called XXXbat.dll or\r
+@REM XXXlibsupportbat.dll, where XXX is the name of the corresponding\r
+@REM tool chain. Replace the '<libsupport_plugin>' parameter\r
+@REM below with the appropriate file name. Other plugins loaded by\r
+@REM C-SPY are usually not needed by, or will not work in, cspybat\r
+@REM but they are listed at the end of this file for reference.\r

+This is the firmware for the ATTiny controllers on the Atmel BC100\r
+development board. Current, the project files are designed to compile\r
+for the ATTiny861 microcontroller.\r
+\r
+The firmware is based on Atmel's IAR firmware code with a port to\r
+GCC. See README.GCC for more information about the GCC port.\r
+\r
--- /dev/null
+The initial port from IAR to GCC was performed on March 12, 2008 based\r
+on code provided by Atmel with an release date of September 4, 2007.\r
+\r
+A log of changes to the GCC code is in the file GCC/ChangeLog\r
