Re: Unreliable GPIO

Hi Jeeves
You can not use a 1MHz sample rate to detect this type of problem! If it really exists. Use 24 MHz sample rate.
Correct the problem of your Logic Analyzer. What is your analyzer?
May be I help you.

Finally I'm interested in ESP32-IDF, with Visual Studio Code extension

In 2018, I made an tutorial - how to use ESP32-IDF (in portuguese). And I was very disappointed. https://jgamblog.wordpress.com/2018/02/09/conhecendo-o-esp32-usando-esp-idf-4/ Today makers don't want to use line commands, many complex tools with dozen of parameters. He wants a fast, efficient and si...

Re: I2C not sending anything

Hi,
Good tool to verify that the I2C interface is working well is the I2C scanner.

If you want to decode signals, use a cheap logic analyzer.

Re: Pwm not super stable

Hi, The LED PWM on ESP32 is incredible stable and has high accuracy! The best I've ever seen! But you must know how to use correctly. Example to 1000 Hz. Setup frequency : 1000 Hz Select channel : 0 to 15 Setup resolution : 15 (more accuracy) maximum available frequency is 2441 Hz ( 80MHz / 32768) S...
