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...

Hi Aidin, I suggest you read the manual with attention. Wich revision is your ESP32? https://www.espressif.com/sites/default/files/documentation/eco_and_workarounds_for_bugs_in_esp32_en.pdf Findout Revision: https://github.com/espressif/esp-idf/blob/master/examples/get-started/hello_world/main/hello...

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.

Hi,
See if it is the same problem:
ESP IDF installation error: Unexpected end of archive

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...

Hi, If you really need to measure the duration of the WIFI or another ISR, you can use this method (used by me) : Setup one GPIO pin as an output. Before ISR, put this pin LOW. When ISR starts, put this pin HIGH (inside Interrupt handler). At the end of handler put this pin LOW. An then with one che...

Hi ,
The same problem ocurred to me (Windows 10).
My solution to this was to delete all files of directory "C:\Users\User_name\Desktop\esp-idf
And run the setup again.

Hi Aidin, See the captured image from my Scope Tektronix TB1062 (60 MHz / 1 Giga Samples/s). The correct image on the pins GPIO2 and GPIO4 is below. No problem.. Arduino code: void setup() { gpio_config_t io_conf; io_conf.mode = GPIO_MODE_OUTPUT; io_conf.pin_bit_mask = 0b10100; gpio_config(&io_conf)...

Hi, I suggest you read the chapter 15 (Remote Control Peripheral) of the ESP32 Technical Reference manual. I think it may be useful to you. https://www.espressif.com/sites/default/files/documentation/esp32_technical_reference_manual_en.pdf and the API reference : https://docs.espressif.com/projects/...

Hi,
My project is not compact, but very accurate and stable.
In fact, it uses one external DVM.
