C6452 UART interrupt service routine

Posted by RdN

I need to write a driver for the UART on the C6452. I managed to get the UART working at 115.2kbps using the FIFO poll mode. However, I require some assistance in getting it to work in FIFO interrupt mode. I have set the ERBI flag in the UART Interupt Enable Register (IER).

What are the next steps in enabling the interrupt service routine (ISR)? Can I use something similar to "interupt void UART_INT()", or should I use the interupt controller (INTC - cslr_intc.h) from the CSL?

I appreciate any advice or help.

Thank you.

Have you tried the PSP drivers for the C6452?

You shouldn't have to write all your own.

If you decide to continue on that path I recommend using the BIOS HWI module rather than trying to use the CSL INTC module.

Maybe someone else can comment on the UART bits. I haven't used the UART.

Hi Brad,

I managed to get the UART on the C6452 working using the DSP/BIOS UART device driver which is part of the PSP.

Thanks for pointing me in the right direction.
