WebIf the chip and programming board are configured for “high-voltage programming”, then 11.5 V is used instead of ground (0 V) to signal reset. Because microcontroller pins are connected to much lower voltages in projects, the standard 0 V to 5 V signals will not cause a reset, and that pin can be used for input and output. WebThe chip in-situ: I have found several posts and layouts for high voltage programming, often based on Uno or Mega arduinos, and always targeting DIP form factors AVRs like ATTinys. None was about Mega2560 as a target, and none is about in-site reprogramming.
