hey...
I bought a new pic16f84A. The programmer didn't program it too. :cry:
I don't know if it is meter, but instad of 74ls07 I have 74ls06, I inverted output(D0), input(ACK) and clock(D1).
it doesn't pass the verify...
and another point, when i read information from the pic the vpp led is blink. should it be like this????
in the normal work of the pic MCLR should be 5V. on the reset this pin should be 0V and in programming mode 14V.
I think that when I read the info the programmer delete it from the pic...
Am I right???
What should I do to fix it????
