hi,my name is indra.i'm an indonesian student. i have a handmade programmer using 74LS07 which is dowloaded from one of F84 programmer website. i made some simple program using MPLAB and succesfuly compiled. but when i try to download it to my PIC16F84A by using WPicProg16 from dontronic, i got some error
"programmed verify failed on line 0, programming abborted".
Then i try to use PICALLW/P16PRO v0.15a FREE MODE!!! but error still occured
"address=0000 buffer=28BA device=3FFF"
and suddenly my ic 74LS07 became HOT...would you mind giving me solution how to solve my problem??? what wrong with my programmer?? :cry:
please help...

It usually means the PIC isn't switching to programming mode, but if your buffer is getting hot there's obviously something badly wrong, so it's not likely to work.
:wink:
Ok the error message you are getting means that the programmer is failing on the 1st location of the chip, i.e. it can't program anything...
Does the 7407 get hot WITHOUT the pic in the programmer? if so then the programmer is wired incorrectly. If the programmer gets hot with the pic in then it is possible that the pic is in the wrong way, try turning the pic round :wink:
Never had much luck getting mchip samples, they ask to many questions, like what's it for, how many are you going to buy, what's your dad's best friend car registration number etc......
In fact I supose that is one of the main reasons that I started/stuck with the PIC, because the prices of them are so low...... but I always try to develop ideas/code on the smallest pic possible with regard to cost of the final product. This isn't always the smallest cheapest PIC, i.e. if you have to stick 5 74/40series chips (4019 for extra ports) etc to use the "cheapest" PIC, it doesn't always work out the cheapest product.....
as i have f84 programmer i am not getting any heat but i am unable to write to ic i am getting the same programming line error but i am able to read,verify,erase need a solotion i an using winxp
