How to use multiple serial ports on CC2642R? Can 3 serial ports be used? [Copy link]

As the title says, the manual of CC2642R says – 2× UART,

1. Can it be understood that there are 2 hardware serial ports, and then the Sensor Controller can be used to simulate one serial port, so that 3 serial ports can be used?

2. If you need to use the USB serial port to burn the program, which two pins are fixed to use?

3. Is there any reference documentation for the serial port driver?

as follows

1. Yes, it has 3 UARTs
2. The CC26XX UART pins are defined by the customer.
3. Please go to the SDK driver: C:\ti\simplelink_cc13x2_26x2_sdk_3_10_00_53\examples\rtos\CC26X2R1_LAUNCHXL\drivers\uartecho
