Re: ESP32-C6 internal 150 vs 32 kHz RC oscillator

Hello Marius28 ,
Using another RC oscillator will not solve the time deviation problem. You need a more precise clock source.
A typical solution to reduce the time drift in sleep mode is by adding an external RTC clock.

Re: Is the IEEE 802.15.4 stack oficially docummented?

Hello @gruvineo,

The register-level information for the IEEE 802.15.4 stack, similar to Wi-Fi/BLE, is proprietary and is not disclosed publicly.

Re: Location of CAN driver / example

Hi @ViennaTom, The CAN peripheral has been renamed to TWAI. For the background see Why rename CAN to TWAI?

Re: Conlicts in the pinout documentation in the User Manual.

There is no conflict or difference. ESP32-C3 AT uses two UART ports: UART0 is used to download firmware and log output; UART1 is used to send AT commands and receive AT responses.

Re: Troubleshooting RGB LED Blinking Issue on ESP32-C3

Hello Micael, a series of pulses should be sent to addressable RGB LED to turn individual colors on or off. A single call to gpio_set_level() will send to a GPIO only a single on or off signal. Please check the original blink example from ESP-IDF for a complete code that is using led_strip driver to...

Re: ESP32-C3 max speed?

Hi g4km4n, SDIO should be the fastest option but ESP32-C3 does not have SDIO peripheral.

Re: Should the reset (EN) pin have an RC circuit?

Hi IamDikoy,

RC circuit at CHIP_PU pin is indeed recommended. Check the Section "2.2.1 Power-on Sequence" in ESP32 Hardware Design Guidelines.
