hi Charles,
What errors are displayed in the MPLAB output window.?

 

[Pommie]

You can't take code written for an 18 series chip and just change the include file to 16F876.

Mike.

i am trying to use the PIC16F876 to run three LEDs which will respond to the DMX512 input signal

hi,
As Pommie has explained you cannot just change the PIC type.

If you wish to use a 16F876 you MUST use the correct CONFIG also the correct statements in the program.

 

[charles01]

I was trying to follow the example form the books and i guess they don't put everything
What is the difference with the CONFIG for the 18F and the 16F PICs
Now i have to find the correct coding for the PIC16F876.
There is an example in document AN1076 from microchip and it uses the PIC18F so i thought it might do the trick.

hi Charles,
The difference between the 18F and 16F CONFIGs is major.

Look at Nigels PIC tutorials, the link is near my signature on this post.

 

[charles01]

thank you eric for the links, i will look at them straight away
