pickit2 zif
Hi.
I've build my new pickit2 programmer...and it's almost working.
Pickit2 detect and communicate with my board fine, but i have some problem in my VDD pin. During tests (from troubleshooting), i got and error: "An external voltage was detected on VDD pin at 2.7 volts" (in red)
Also, in mplab i got this error: PK2Error0023: Target Vdd measured at 2.64V which is outside the programmable range of this device ( 3.00V - 5.50V)
what could be wrong? Maybe R20 resistor (2k7) should be less?
This is the design that i'm using:
http://tecmb.com/pickit2_clone.html
PS: i'm not using memory's, it's empty (just socket on board) becau'se i'm not interested in programmer-to-go now and i don't wann waste $$ on those.
tks
Added after 32 minutes:
Solved.
Just put an 100nF ceramic cap in VDD-GND and it's working fine now. [i didn't tested programming a pic]
Now i need another thing: universal target board. Anyone know any good design for use with ZIF and pickit2?
