Hi all! My Willem Programmer doesn´t detect the PIC16F88. After reading the Datasheet i´ve built an ICSP adapter with this wiring: ICSP PIN -> PIC 1 VPP -> 4 2 VCC -> 14 3 VSS -> 5 4 PGD -> 13 5 PGC -> 12 But no sucess. I can´t read the ID. To be sure LVP is deactivated I also tried to pull down PGM...

Fortunately I found a BC807 right away and replaced the old one. Hurray! VCC is back again! Now, i can control all Test-HW pins :D Ezo, you are my hero of the day! But i still get this damn "Check Power and Connection" error. After doing some google I finally found a solution: PortTalk After downloa...

Q1 is directly connected to the VCC pin
But its SMD, i cant read the type.
May you know which i couldt take?

Thanks again.

So i can set ZIF pins Vcc, A19. A20. A21, A22, A23 to 0/5V If A19 is working, all prior adress should work. Let measure on contacts of ZIF32 opposite side (soldering side). Check connection and resolder all ZIF 32 contacts ! Hi again! You´re right! i checked the ZIF socket exactly and noticed some ...

Hi Ezo! I allready did measuring if i connect the programmer i can control Vpp, Vcc LED and A19-A23 but measure 0V on the zif socket all the time. So i can set ZIF pins Vcc, A19. A20. A21, A22, A23 to 0/5V and Vpp has correct voltage, too according to jumper settings. All other ZIF pins = no reactio...

Back again!

I checked Vdd/Vss on ICs 4015, 4021, 4069 and measured 5V.
I figured out one 4015 ontrolls A19-A23 so i guesss another 4015 must make problems.
Is there a way to test it?

Hi again! I am really surprised you have activated programmer with PCI-LPT card before. The only thing i´ve done was to use the remapped io.dll from web. Goods news: I tried again to control data lines D0-D7 via the software with success. Maybe last time i unintended selected a wrong port :roll: Now...

Thank you for your quick help Ezo! I´ve checked the data lines like you said: 3,4V no matter if activated or not! My LPT cable is ok. So it shouldt be a software problem... My LPT card driver is correctly installed, polling is deactivated, port adress is BC00 and "IO.ini" is also edited. But i haven...

Hi all! After one year my Willem 5.0C (dual/USB powered, SMD ICs) suddenly stopps working and isn´t recognized anymore "Check Power and connection". I am using 0.98D10 software with the remapped io.dll because of my PCI-LPT card and everything was fine until now. I allready tried another PC without ...
