Firstly, I have to say that I'm new to PIC family. I am trying to build USB-CAN converter from USB-TIN page using PIC18f14k50 microcontroller, PICkit3 programmer and MPLAB IDE.
After writing hex file to flash memory device is not detected by PC. I tried on different OS and PCs.
I decided to read back flash memory after writing. It turned out that hex file that I've read is different from what I've tried to write!
What have I made wrong? Any ideas?
Look at my hex files. I read a lot of "FFFFFFF..FFF" sectors. Some adresses and data are consistent, but only just a few.
