[Kirill] wrote in to share his Arduino-based PIC programmer. It is capable of writing to the 18F family of chips, including 18F2XXX and 18F4XXX. We think that’s pretty exciting because this line of ...

💡 Note: Some PIC microcontrollers require 12V on MCLR for high-voltage programming. If this is the case, you might need an external 12V circuit.

It is recommended to isolate programmer from battery circuit. I did not do any intense research in that manner but for safety i have utilized 220ohm resistors at clock and data lines. "Test PIC" will ...

While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies of ...

Many PIC processors require 5-V power while being programmed, yet battery-powered systems may contain low-voltage devices that will be damaged at voltages above their maximum voltage ratings. In ...
