To use GCC 142 * the source have to be modified.\n 143 * \n 144 * To make project on IAR EWAVR:\n 145 * Add the .c files to project (ADC.c, battery.c, main.c, menu.c, 146 * OWI.c, PWM.c, time.c and USI.c). Add either LIIONcharge.c or NIMHcharge.c, 147 * and update LIIONspecs.h or NIMHspecs.h, and battery.h with the appropriate 148 * battery data if needed.\n 149 * \n 150 * Use device --cpu=tiny861, enable bit definitions in I/O include files, 151 * optimization low for debug target and high for release, output format: ubrof8 152 * for Debug and intel_extended for Release. \n 153 * 154 * \section deviceinfo Device Info 155 * This application is based on the ATtiny 861, but it is possible to migrate 156 * the design to other AVR microcontrollers, such as pin-compatible devices 157 * ATtiny 261/461. Low pin count devices such as ATtiny 25/45/85 may also be 158 * used, but with reduced functionality. 159 * 160 * Required fuse bit settings: 161 *
