Re: [Usbpicprog-technical] 16C devices

[Matt H. <mh...@me...>]

Frans,

I got a chance to try 130529. It seems like things are not quite working 
yet. The 16C622 isn't autodetected. I get this on the command line:

ReadId: 00
ReadId: 00
ReadId: 00
ReadId: 00
ReadId: 00
ReadId: 3fff
ReadId: 3fff
ReadId: ffff
Autodetected PIC ID: 0xffffffff

Manually selecting the part and attempting to read it returns all 
0x3fff. I also tried programming a part, but it fails on verify. Also, 
the GUI leaves the "erase before programming" flag checked when 16C622 
is selected -- which doesn't make sense when a 16C part is selected. (It 
fails on the erase step without getting to the programming).

I tested my programmer with the 130529 firmware on a few grab bag parts 
- 16f876 and 16f84, and both read and programmed successfully. Just to 
be sure I measured my VPP while connected to the chip, and it came it at 
11.92V.

I'm happy to help with any debugging info you might need, and I really 
appreciate your taking the time to implement support for this. However, 
if it's going to be a headache for you it's ok by me to drop it.

Best,
Matt
