Pickit3 program can’t recognize chip
Hello,can anyone here help me out?
The tip is given below:
Target Device ID (0x0) is an Invalid Device ID. Please check your connections to the Target Device.
It can be programmed after changing chip, and the circuit is no any problems.Here the original chip is also continue to work. But I don’t know why it can’t enter into programming ! The chip I used is PIC18F45K20.
This is the PIC18F45K20 datasheet: http://www.kynix.com/uploadfiles/pdf8798/PIC18F45K20-E2fMV.pdf
Please look the details from it if needed.Can you help me solve it?
Thanks a lot!
