Ako programovať AVR ATmega328p pomocou CMD:

(C-code “.c” + (avr-gcc compiler OR avr-g++ compiler) -> binary “.elf” +   (avr-objcopy) -> intel “.hex” + (avrdude) -> to flash AVR(bootloader))

  • avr-gcc -mmcu=atmega328p -Wall -Os -o button.elf button.c
  • avr-objcopy -j .text -j .data -O ihex button.elf button.hex

  • avrdude -F -v -p m328p -c stk500v1 -P \\.\COM3 -b 19200 -D -Uflash:w:”button.hex”:i

    Is D4 and D5 for SDA / SCL wrong? I think it should be A4 and A5.
