Hi guys.
I want to program a PIC16F877A through IC-PROG (people say it's a very good software).
I also built a hardware in order to program it, following the schematics AN589 (
https://www.electro-tech-online.com/custompdfs/2010/02/an589.pdf).
Everything is connected the way they are supposed to be. However, when I run IC-PROG and should have my ic burnt, I get the message "Verify failed at data address 0000h!" after programming and verifying. (It means nothing was even burnt, right?)
I've already checked the parallel port and I'm able to access it.
And I realized that when it's in 'programming mode' (when the software says it's being programmed) the voltage in MCLR is 13,5V, while in non-programming mode it's 5V. So, does it mean the ic-prog is really trying to program PIC?
I have tried to adjust delayIO, but nothing worked ):
Maybe the software IC-PROG are misconfigured, I don't know what's going on.
Can anybody help me?
I'm running out of ideas of what to do!
Thaanks.
