Hi, can you please provide some methods and commands for using the UART as GPIO as well in this board, in the CCS.

Thanks and Regards

Hi,

So, the pins are configured as UART function at the first place. Then you want to change the pin function to GPIO. Is that correct? It should be okay to call DL_GPIO_initDigitalOutput() to set the pins back to GPIO output function. And then you can call DL_GPIO_initPeripheralOutputFunction() and DL_GPIO_initPeripheralInputFunction to reconfigure the pins back to UART function. You might need to call the SYSCFG_DL_UART_0_init() when the pins configure back to UART function.

Best regards,
