Hi team,
Here's the request from the customer:
Customer found such notes in CC1310_LAUNCHXL.c of tirtos_cc13xx_cc26xx_setupwin32_2_21_01_08:
/*
* ========================= IO driver initialization =========================
* From main, PIN_init(BoardGpioInitTable) should be called to setup safe
* settings for this board.
* When a pin is allocated and then de-allocated, it will revert to the state
* configured in this table.
*/
He is confused that setting DIO4 as the TX pin of the serial port in the uartCC26XXHWAttrs structure and then setting DIO4 to input pull-up mode in BoardGpioInitTable as well as executing the PIN_init(BoardGpioInitTable) in the main function. Then open the serial port and send data. After the data transmission is completed, close the serial port. At this time, will DIO4 automatically return to the pull-up input mode?
Could you help check this case? Thanks.
Best Regards,
Nick
