pinMode vs gpio_set_direction for UART

[michcfr]

Hello,
I am using the UART1 (RX:pin16 and TX:pin17) and I need TX to be push-pull output, so I used gpio_set_direction like this:

Code: Select all

#define Sender_Txd_pin 17
...
gpio_set_direction((gpio_num_t)Sender_Txd_pin, GPIO_MODE_OUTPUT);

But it is not possible to send data (println) through the UART. However, I can send data when I replace the above line by:

Code: Select all

pinMode(Sender_Txd_pin, OUTPUT);

My questions are:
-What did I missed to add before or after gpio_set_direction?
-Is pinMode(Sender_Txd_pin, OUTPUT) equivalent to gpio_set_direction((gpio_num_t)Sender_Txd_pin, GPIO_MODE_OUTPUT) to get TX push-pull output?

thx
Michel

pinMode is more than that:

Ok, see. Thx
When calling pinMode(TX_pin, OUTPUT), is TX_pin In push-pull output mode?

Hello
Can somebody help me on hox to know if calling pinMode(TX_pin, OUTPUT), makes TX_pin In push-pull output mode?

thx
