Hey everyone!
I need some help with programming this Atmega328p. It was doing fine until it stopped programming properly one day.
I’ve checked the solder connections, replaced the chip and all of the wires for programming, but to no avail. The issue is that the device signature shows up as 0x0000
Any thoughts on how to fix this are very much appreciated! Normally, that would indicate an issue with power/connections, but it worked before, so I'm not sure what the issue would be. The input voltage is 3.3v.
