Hi guys im just connecting the 328p (already programmed using its pcb that i picked it from) to nano using TX to RX UART way it looks like i dont get any data from the chip.
Heres the breadboard
(atmel logo looks 180 degrees rotated on this view)
ignore that st7789, that nano has a program that serial.println's what it got with the same baud rates as chips program (for debugging)
nope.I upload the blink program but for pin 11 and then unplugged the atmega from uno yesterday. after 999999 trys i made it work. but this program is about UART
Hi,
Please draw and post an image of your circuit.
For the 328 to function, it has to have a clock, this is usually provided by an external crystal.
Can I suggest you look at the schematic of a UNO and see the surrounding components needed to make it work.
