why not 1wire slave macros?
I need to connect two microcontrollers over a long distance

look at this

hi guys, tell me what I'm doing wrong. I need to connect two microcontrollers via 1wire

what's the difference I don't understand, everything works for me on arduino uno (atmega328p) I download via ISP, but why doesn't it work on 2560 mega ???

this one through the isp port I upload the firmware hex file

martin i did everything you said, but the board still doesn't work. now again checked through microchip studio everything is working correctly

well, why blink works through microchip studio, but FC9 does not work ???

I am using arduino mega 2560 board.
microchip studio everything works correctly
