Need Working Example for MCPWM Capture (or RMT) to Measure Frequency on GPIO36 – ESP32-WROOM32 / ESP-IDF v5.2.5

Hi everyone,

I’m stuck trying to measure the frequency of a digital pulse signal on GPIO36 of an ESP32-WROOM32 (ESP-IDF v5.2.5). I hoped to use the MCPWM capture mode, but after days with the official docs and scattered snippets I still don’t have a working solution—and I haven’t found any up-to ...

Help with INA219 Library on ESP-IDF

Hello everyone,

I'm trying to work with the INA219 on ESP-IDF.

I'm having a really hard time trying to port any Arduino libraries to ESP-IDF, and the library: https://github.com/UncleRus/esp-idf-lib/tree/master/components/ina219 , which should already be fully ported, just isn't working for me. It ...

Help Needed: J1939 Protocol Integration on ESP32 with FreeRTOS

Hello,

I am an electronic product developer, and historically I have developed with PIC MCUs, having implemented a J1939 protocol on PIC 'from scratch'.

Now I am starting a project that will also use the SAE J1939 protocol. However, in my initial research, I am having difficulty finding any ...

Re: Task Watchdog Triggered in ESP32 Application Using u8g2 Library

Hey everyone,

I've spent the last few days diving into FreeRTOS tasks and, wow, I'm blown away by the possibilities. I'm a veteran of direct MCU programming, typically working with "bare metal" programs. Recently, I needed to shift to a more powerful processor. I was trying to squeeze my system ...

Re: Task Watchdog Triggered in ESP32 Application Using u8g2 Library

Hello @MicroController, thank you for your response.

Indeed, the issue only occurs when I'm stuck in a loop waiting for some interaction. At a certain point, my code gets stuck in a loop that just tests my keyboard looking for any interaction. But when I call more complex functions, like serial ...

Task Watchdog Triggered in ESP32 Application Using u8g2 Library

Hello,

I am writing a program that, among many things, keeps an LCD screen constantly updated. I have a clock on the screen that displays hours, minutes, and seconds. Thus, I end up calling my screen update function at intervals of no more than 1000ms to show the new time. To update the screen, I ...
