Hello there
I recently bought one of your programmer and was very satisfied with it
EXCEPT i know nothing about PIC and i am learning
I know how to code them in C and i am simulating all my circuits in ISIS (Proteus extension i think...)

I received a complementary chip with my programmer, and so far my codes in C only worked on that chip (12F629)

So i am having a problem coding a 16f877a

I am using mikroC ...
Do you recommend a better software BUT that doesn't use ASSEMBLY language because i found it so complex at first :D

If there is anything i should know please let me know
I can provide my codes if you want to

mikroC should be fine as long as you can write it and it can be compiled into .hex.
C language is a pretty good one if you can use it.

Thanks for the reply
Yes i can write in C and simulate them in ISIS
In the ISIS, when i simulate the hex file with the circuit it works
But when i do it in practical it doesn't
I am sure of all the connections and the programmer is working fine..

Is there a chance that the chip is burned or malfunctioning ?
And would the programmer i bought from you tell me if the chip is burned?

if the chip can be verified, then the chip is porgrammed correctly.
check your CFG bit, see if it is set correctly.

checked the CFG, all is good
i think my problem is in the OSC circuit
can you show me a circuit of what i should build to use with my 8MHz crystal ?

the reason why it worked on 12f629 i think is because it uses its internal oscillator which is not found in 16f877a

and considering this is my first time around these things, i don't think im doing it right :(
