Re: Reading DS18b20 sensors using ESP-IDF using a ESP32 with a 26 MHx XTAL

Sorry for the noise. The board came with a inverted/mirrored pinout diagram! I've already alert the store. Everything is working now and there is no difference in the RTM initialization.

Re: Reading DS18b20 sensors using ESP-IDF using a ESP32 with a 26 MHx XTAL

Thank you @WiFive. I've check both logs (for the Allnet-IOT-OLED and the standard ESP32-WROOM-32) and both seem to use the same 80 MHz clock source for the RMT initialization. ESP32-WROOM-32 log (working): I (0) cpu_start: Starting scheduler on APP CPU. D (297) heap_init: New heap initialised at 0x3...

Reading DS18b20 sensors using ESP-IDF using a ESP32 with a 26 MHx XTAL

I'm able to read DS18B20 sensors using the example code provided in this repository https://github.com/DavidAntliff/esp32-ds18b20-example . It works well using a standard Espressif ESP32-WROOM-32 (aka ESP32-DevKitC), which uses a 40 MHz XTAL. I'm not able to run the same example using an Allnet-IOT-...

Re: IDF Monitor output is garbled

I had the same problem with an ESP32+OLED https://www.allnet.de/lp/iot-wlan-display/

I've set the Main XTAL frequency to Autodetect and it works.
