PIC willem pcb 5.0, need it very bad
Recheck. What is voltage on ZIF32/1 and PLCC32-1 without Test H/W box activating ?

PLCC32-1=12

Can you send me picture of your programmer or give a link ?
Is here voltage change on PLCC32/1 when remove jumper in right side from bottom PLCC (below 2 jumpers group ) ?
Reconnect programmer and check no soldering shorts on lines from PLCC32/1.

Tis is the one that i bought from ebay.

the pic of it is below
i tested with J11 while the jumper is off with the same result 12. i will check for short tomorrow... hope i would figure it out how:)
Thanks alot for your help and good night

Re: PIC willem pcb 5.0, need it very bad
I checked the backside of the board without finding any soldering shorts.
Re: PIC willem pcb 5.0, need it very bad
Check are all ZIF and PLCC pins connected 1:1. Check e-mail.

what about email?Ezo писал(а):Check are all ZIF and PLCC pins connected 1:1. Check e-mail.
How do u mean i do shall i check the zif pins to ground and the plcc or shall i do it against each other?
Re: PIC willem pcb 5.0, need it very bad
measure resistance (cofirm shor) between ZIF and PLCC pins 1-1, 2-2,...

Re: PIC willem pcb 5.0, need it very bad
Measured positive values between 0.4-0.6 in all pins except pin 1:1 and 32:32. here i get a different very higher values that blinks for a second and then disappear again. so i think the connection 1:1 and 32:32 ar faulty. btw i did this wile device off power, shall i do on power?
i didn't get any email yet?

No.btw i did this wile device off power, shall i do on power?
I will resend from another mailbox.i didn't get any email yet?
Or it is bad design . Find where pins are connected, details were in mail.so i think the connection 1:1 and 32:32 ar faulty
