Thanks.

Should I create a github issue for the driver and how it calculates the clk_speed?

Hi, For: ESP-IDF v3.3 I want to configure a low I2C clock speed of 1K because I want to use the ESP32 in combination with a few slave devices using a relatively long cable of 1 meter. I cannot use another data protocol in this project. The ESP-IDF docs do not specify a lowest I2C clock speed so I as...

No matter what I supply for the VREF param it always gets set to 1100 because the fuse takes priority.

FYI I'm also using the Lolin D32 board intensively. I have always assumed that the fuse takes priority and there is no way around that. But I hope I am wrong.

I see 2 possibilities: 1. esp_log_timestamp() https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/system/log.html?highlight=esp_log_timestamp#_CPPv417esp_log_timestampv This also includes the time in the bootloader. 2. xTaskGetTickCount() * portTICK_PERIOD_MS https://docs.espressif.c...

The toolchain is part of https://dl.espressif.com/dl/esp32_win32 ... 181001.zip which is described on the instructions page https://docs.espressif.com/projects/esp ... setup.html

Hi, You can try to change in menuconfig the "RTC clock source" to from "Internal 150kHz oscillator" to "Internal 8.5MHz oscillator divided by 256". The accuracy should improve. The online help in menuconfig provides more information: - "Internal 8.5MHz oscillator divided by 256" option results in hi...

Hi WIfive, Thanks for the review! I have created a 0.8V power rail and used that for the pullups in this test. Test#1 (my production setup): - Menuconfig: "(*) External 32kHz oscillator at 32K_XP pin" - RTC board pin "32K" => 10K pullup resistor => Power rail 0.8V (this pullup is specific for the DS...

Hi, For ESP-IDF v3.2 in combination with Adafruit HUZZAH32 (ESP32-WROOM-32 module). This question is about the technical documentation and configuring an external 32Khz oscillator in EDP-IDF. I'm searching for instructions on how to use an external 32Khz oscillator output signal as input for the ESP...

Hi Gunar, Thanks for trying. To be complete, I also import the attached XML file as follows: Project -> Properties: C/C++ General -> "Path & Symbols" property page -> tabIncludes: For Language="GNU C" Do: => Import "esp32-eclipse-includes.xml" # Do the following every time you copied files into the ...
