PIC16F1936 General Call problem
PostPosted: Mon Apr 04, 2011 1:39 am     Reply with quote

I have a problem when I try to address my PIC (which is a slave device) with the General Call (00) address. As soon as I do this, the READ/WRITE bit of SSPSTAT register is set to READ. Therefore, the subsequent data clocked by the master device does not make it to the SSPBUF register of my slave device.

Has anyone seen this problem before?
I believe I have set my registers correctly, and can post them on this site if required.

Many thanks in advance.

What happens if you use a different PIC, such as 16F877 ?

(and, what's your compiler version ?)

Sorry for the delay, it has been manic at work.

The General Call seems to work absolutely fine when I used a PIC16F767.
However, it was decided to change to the PIC 16F1936 as it is a newer device with on board EEPROM.

The compiler version is 4.119.

Thanks for looking into this.

Regards

Steve
