UART functionality with PER test project

vamsi krishna kathi

Hi,

 I wanted UART functionality in PER test project. There is a hal_uart.h file already present but there is no hal_uart.c file present.

So effectively there was no uart functionality supported by the PER test project.

I included hal_uart.c file from SerialApp project into PER test project.

But still the uart call back function does not get triggered on data being received at UART.

I feel hal_board.h and hal_board.c files in PER test project are different compared to that in SerialApp project.

These two files along with hal_board_cfg.h file are to be configured properly for UART to work properly in PER test.

But I could not figure out what all needs to be changed in these files.

Could some one help me regarding this?

Thanks and Regards,

Vamsi.

    Please refer DN112 swra222b.pdf  for UART details and sample code. 

    The attached code may be a quick start for you that uses UART0 ALT1 on P0.2 RX & P0.3 TX.
