Using ISR function for informing about receiving from USART

ISR for receive in USART

Hi everyone,

I need some helps on this! I would like to know wat should I do in the ISR function if I want to be informed about receiving something from USART at anytime. Do I just check the RCIF flag? Wat bit do I need to initialize to get the ISR working properly? I'm using PIC16F877 anyway.

Thanks for any help!

Regards,
Eric

If you are using Hi-Tech PICC compiler you can get a lot of info here:

Thanks for ur help! I got it working now by checking both RCIE and RCIF in the isr interrupt function. Btw, how did u know I'm using Hi-Tech PICC compiler?

I thought that you are using it (so do I) because you would not have asked if you were using CCS as this compiler has a built in function for nearly everything

But you can get a lot of problems if you try to reuse CCS code with another compiler on another architecture ...
