High voltage programming
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. WebFeb 28, 2024 · High-Voltage Serial Programmer. The voltage we’re talking about is only 12V. AVR chips have a backdoor to recover them, and precise timing and 12V are all that is …

WebApr 5, 2013 · For high voltage programming you don't need the external crystal, I am pretty sure: HVSP and HVPP can be used to reset the fuses without external clocking. I am not sure what method your programmer uses. If ISP, then you'll need the external clocking mechanism to reprogram once you've set the fuses for external crystal/resonator. Share … Web5.
