Re: ICSP error
Hi,
If you are saying that you can program the pic in the programmers Zif sockets but when you connect the jdm to the pic in the working circuit you get errors, then something in your circuit must be affecting it.
The Pic chips Mclre, pclk and pdata must be isolated from any other circuitry otherwise it can affect the signals from the jdm.
I know how to isolate those signal electronically with the Pickit2 programmer but do not know if / how it can be done with a jdm - sure others will come in and help out here...
Just out of interest can the JDM program a pic18F2550 chip ?
