Hi all!
I've searched the forums here and haven't come up with a solution that works for me. I can program my PIC, but cannot read from it. I have a PIC 12F675 hooked up to a JDM programmer and am using WIN PIC for programming it.
The Vpp is being raised to 12.75 volts. What value should this be? The datasheet for the 12F675 doesn't specify the exact value, oddly enough, just referencing a programming reference manual, which I cannot find.
Everything works just fine (read/write) when using the DIY K-149 programmer. However, when I use the ICSP off of the K-149 to the same DIP 12F675, it too cannot read. This is using the MicroPro DIY K149-BC PICMicro Programmer v141204 and protocol P018.
I even hooked up the PIC straight onto the ICSP programming wires. How is it possible that I can write but not read??
Any suggestions?
Thanks,
Dan
