CC1310: UART PEEK/number of bytes available in FIFO option not available

Hello Ali,

Talking to one of my colleagues, the recommendation is for the application to read the UART data and then use it or discard it. The "./simplelink_cc13x0_sdk_3_10_00_11/source/ti/drivers/uart/UARTCC26X0.c" driver is not designed to be power efficient and hence it's not used with the examples provided with the SDK.

If your system does not require low-power then you can switch to using the "UARTCC26X0" driver.

I haven't tried this so far, but to switch to using "UARTCC26X0" driver, you will need to modify the ".fxnTablePtr" element of "UART_config" structure in the board file (CC1310_LAUNCHXL.c) of you example/application.

Hope this helps!

Regards,
Sai

Replace the following lines in CC1310_LAUNCHXL.c file of you example

#include <ti/drivers/uart/UARTCC26XX.h>

and

const UART_Config UART_config[CC1310_LAUNCHXL_UARTCOUNT] = {
    {
        .fxnTablePtr = &UARTCC26XX_fxnTable,

with

#include <ti/drivers/uart/UARTCC26X0.h>

and

const UART_Config UART_config[CC1310_LAUNCHXL_UARTCOUNT] = {
    {
        .fxnTablePtr = &UARTCC26X0_fxnTable,

Thanks,

Sai

Hi sai!
So here it goes...my long journey of finding the solution to this problem is over now finally...i have achieved what i wanted to achieve...here is how it went down finally:
I upgraded to the latest sdk 3.10.i was previously running a very old version which didnot have support for UART26X0.c drivers.
I changed my uart function table as told by yourself but it wasn't enough i had to also make some changes to the UART hardware attributes object in the launchxl.c file...remove the power management id change some macros to X0 instead of XX and the UART26X0.c was ready to use as the program built without errors.
Then i used the following method to peek bytes in the uart fifo ring buffer and then read any number of bytes i want from that ring buffer.
UART_control(uart,UART_CMD_GETRXCOUNT,temp);
temp variable returns the number of bytes available in the fifo at this point.
then i used a uart read for exact number of bytes as temp variable as follows:
UART_read(uart,uart_buffer,temp);
I was able to read the exact number of bytes as available in the fifo,something that really takes the burden off from the processor of reading uart data byte by byte.
My application is to find the number of number received over uart in 10ms and process them over radio without causing a race condition while new bytes arrive and the old ones are still processed.
Thank you so much for your support and guidance..
Looking forward for more success and learning in future
