but using the miso mosi and sck pins to program the 328p chip wont allow me to communicate with it through the serial monitor while using the mega2560 as an isp. ive been reading about using the mega2560 as a usb/ttl by connecting GND to reset then connecting the rx/tx pins to the 328p, but so far have come up empty handed.
can this be done with an arduino mega2560? i want to be able to use the serial monitor to communicate with the atmega328p on a breadboard while i use the arduino mega as an isp.
I'm having trouble using the serial monitor to communicate with the atmega328p chip? Im using the arduino mega2560 as an isp to program an atmega328p on a breadboard, ive been successful in loading the bootloader and test sketches like blink to the chip, but now im trying to test a simple sketch that allows me to input a char into the serial monitor and should return a statement based on whether it reads the right char. So i uplaod the code just to the arduino mega2560 and it works fine, but when i turn it into an isp and upload it to the atmega328p on the breadboard i can no longer communicate through the serial monitor.
