CC1312R: Is there a way to get Sysconfig to use UARTCC26X2 instead of UARTCC26XX?

Part Number: CC1312R
Other Parts Discussed in Thread: SYSCONFIG, CC1310

Hi,

I am migrating from simplelink_cc13x2_26x2_sdk_4_30_00_54 to simplelink_cc13xx_cc26xx_sdk_5_30_00_56. Collector and Sensor examples.

I wrote a custom UARTCC26X2.c driver for my application as I had to add in some tri-stating for coms across a single wire interface. It has worked well.

My driver is based on UARTCC26X2, but it appears Sysconfig is using UARTCC26XX even though I have a CC1312R. The functionality between these two drivers is different. I could simply deselect a UART in Sysconfig and just use my own device config, but I was going for full compatibility with Sysconfig so the hardware set up is easily viewable and editable.

Is there a way to get Sysconfig to use UARTCC26X2 instead of UARTCC26XX?

In other words, have Sysconfig output:

/*
 *  =============================== UART ===============================
 */

#include <ti/drivers/UART.h>
#include <ti/drivers/uart/UARTCC26X2.h>
#include <ti/drivers/Power.h>
#include <ti/drivers/power/PowerCC26X2.h>
#include <ti/devices/cc13x2_cc26x2/driverlib/ioc.h>
#include <ti/devices/cc13x2_cc26x2/inc/hw_memmap.h>

In syscfg you can select between using UART and UART2 under drivers. Did you try the latter?

Hi,

UART2 is entirely different and uses DMA. It would load the UART2CC26XX driver.

I don't think SYSCONFIG will let me use the UARTCC26X2 driver and I need to deselect it and have my own config for this driver.

Thanks

Have you missed the 2?

There are three different drivers.

Sorry for that.

I have to check with SW R&D. Syscfg uses the files under ti\drivers\.meta\uart to setup which driver to be used etc. You can try to modify these files (take a back-up first) if you don't want to wait until I get a feedback from the developers.

Hi,

Okay thanks, and no problem. I have reverted to my old method of manually configuring the UART and deselecting it in SYSCONFIG. It's really not a problem but it would have been nice to have complete integration. I'm not sure of the differences between UARTCC26XX and UARTCC26X2, I thought the former was for CC1310 and the latter for CC1312, but I might be mistaken.

Thanks,

Andy

Found out that this can be done easily from syscfg but it was a bit hidden. If you click on UART to add an instance of the driver and click on the "Global Parameters" line and tick the box you can get the x2 driver.

ah fantastic! My eyes never wandered up to the top of the window. Thanks for looking into this.
