'[PICLIST] [PIC] How to program/read a 16F628 using'

Hi all,

I tried to read the contents of my new 16F628, using my new Warp13 programmer, by placing the Pin1 of the chip in the Pin1 of the ZIF socket in the programmer.
But the data that was read back looks similar to the data that would have been read back when no chip is inserted into the socket (all data -program/eeprom/config bits = 0).
I made sure that the "Force ISP" is not set.

I also tried using MPLAB to read the chip which also gave me the same result.

Can anyone tell me how to program/read my 16F628 ?

Any help is appreciated. Just a note: the programmer has been verified to program a 16F877 without any problems at all.

Thanks and Regards,
Somasundaram.

To program a 16f628 with warp 13, tou have to (add) and use the 18 pin
socket in the upper-right-corner of the board.

I disagree...the documentation says that the 18 pin socket is for the
16c52, 16c54, 16c56, and 16c58. It also mentions that 18 pin serially
programmed devices should be in the 40 pin socket, top justified at pin
one. That said, I haven't tried it yet :)

Well that was stupid of me, I responded too quick before I remembered
the issue with this. In any case, it's not just as easy as using the 18
pin socket, you need to also remove R9. In any case, check out Jim's
page for more details:

Sorry I spoke too soon :)
