Hi,

I’ve come a long way on the use of LEDC.

It turns out that timing by cannaux is risky. On some frequencies, they synchronize randomly.

I ended up doing something, but:


hpoint is innaccessible from the ledc library (see probably to overload the library), with a little help, why not ...

Hi,

He looked a little in the forum before posting. I didn’t know how to find what I was looking for, so I came here to find out.

My specifications:
- I need to generate 4 PWM signals 25 kHz.
- They must start at the same time.

So I started by doing a search. I found indications with "ledc". Ok ...

Hi,
Probably that question was asked. I couldn’t find what I was looking for.

In desperation, that’s what I’ve done, which works perfectly, but I have a very specific point.

I first looked for wifimanager. Ok, there are some, but many are bugged, do not work properly or request third-party ...

Good morning,

The night wears advice, as they say in my country.

So I undertook to use what is indicated here: https://espressif-docs.readthedocs-hosted.com/projects/arduino-esp32/en/latest/tutorials/io_mux.html

This put me on the trail of the following code:

Wire.setPins(2,3);
Wire.begin(0x3C ...

First of all, thank you very much for that answer. It allowed me to go a little bit further.

So I confessed to my platformio.ini the configuration the information indicated in the answer. And it works perfectly. That’s what was missing.

So I’m going to add a little bit of information to my code ...

Good morning,

I have ESP32-C3-WROOM-02 that I took from Mouser. I based myself on the following datasheet: https://www.mouser.fr/datasheet/2/891/Espressif_Systems_04082021_ESP32_C3_WROOM_02-2295851.pdf

I have PlatformIo installed base on VSCODE and I configure my installation with the following ...
