PIC16F877 programmation
Posted: 13, 2010 May Thu 4:13 pm
Hello,
I am using this PIC programer (http://www.tavernier-c.com/programmateur_de_pic.htm) with WxPic 1.2.1 R194 and i am able to program and read 16f84A and 16f628.
But i tried with a 16f877 and it's doesn't work.
I have debugged and i am surpise because, VPP1 (parallel port bit D4) and VPP (parallel port D3) are activated both when read/write operations. I read 16f877 datasheet and only VPP1 need to be apply (pin 1 on the pic). In our case, we appliy 13V on pin 1,6 and 15 of the pic.
Coiuld someone help me to understand if it is normal?
Thanks for your answers
