Re: Not able to set GPIO level

Use gpio_reset_pin() first.

Re: 32k_N XTAL - TXCO

Can you set CONFIG_SLOW_CLK_CAL_CYCLES to 0? This should disable calibration and would make the ESP32 use the external clock input without trying to see if it works first. Then please make sure that the clock indeed keeps running at 1sec/1sec when in deep sleep to verify it actually works.

Re: My esp32 getting very hot and I can't upload the code anymore

Sounds like something catastrophic happened (12V or 5V directly to the ESP32 GPIO pins, possibly via a transistor that has one pin accidentally disconnected or something?) and your ESP32 is fried.

Re: Mysterious freeze/stop in the field

I have been experiencing this exact same issue. My power source is dual battery and solar panel. What is your power setup like? This sounds like the power supply for the ESP32 at times can go below the minimums as indicated in the datasheet, and if that's not handled correctly that can lead to the ...

Re: ESP32S3 - Enabling CONFIG_FREERTOS_USE_TICK_HOOK causes nvs_flash_init() to panic

Iirc the tick hook runs from interrupt context, meaning you should make sure the hook and anything it calls or uses should be in IRAM.

Re: Beginners question esp32 and zigbee

At this point in time, only the ESP32C6 and the (not yet widely available) ESP32H2 can do Zigbee.

Re: Monitor printing unreadable output

Seems your serial port gets opened at 460800 baud; by default the ESP32 outputs data at 115200. (Note that flashing can be faster than that.) Maybe a setting somewhere?

Re: esp32c3 timer registers

Why do you think that? As clarified in the docs, when a timer triggers an interrupt by means of an alarm, it can automatically reload the timer to a set value. That value also can be zero.

Re: ESP32 MASTER - ARDUINO NANO SLAVEs with IC MAX485 and MODBUS PROTOCOL

Well, you're not asking a question, for one, so no one knows what you're in need of help with specifically.
