ESP32 RS485 DTR Pin

Hi,

I'm trying (and failing) to initialize UART0 as RS485 with hardware DE control through the DTR pin.

How can I setup the DTR pin? uart_set_pin(...) only takes 5 params.
The api-reference does gice a _uart_set_pin6 function, but that does not compile. I might be missing an include?

Hi,

We're using the ESP32-C6 in our sensor project and are experiencing random freezes with no debug info or (watchdog)reset.
It's a matter of time before all our sensors become inactive without self recovering. The only way to fix it is a power cycle.

We tried different work-around to get around ...

ESP32-C6 Wrong ADC values after esp_wifi_start

Hi, We like to read ADC values from GPIO0 & 4 while also connected to wifi.
ADC oneshot reading is working before esp_wifi_start(), after the call it always returns 4081.
Is it possible to have a working ADC next to a connected wifi?
