Hi guys!,
I'm working in a firmware with PIC18F452 microcontroller, after compiling and programming the chip, the microcontroller seems not to work anymore. The circuit does not init, and I am not able to reprogram the chip anymore. Im using Pickit2, having a no "device detected error".
I've checked everything and I'm nearly sure that is not a hardware issue. ( Signals PGM/PGC okay, supply voltage levels okay, VPP voltage level okay (using a 10k pull-up, manual device selection, disabling fast programming, and all the software setting variants )
¿Could I have damaged the chip memory o something like that? In that case, ¿is there a method or solution to recover the chip?
Thanks!!
