ESP32-C3 serial access via device links not working

Hi, I currently evaluate an ESP32-C3 Super Mini board because of it's small form factor. I noticed that on linux the device name of the usb serial port changes all the time (e.g. on every press of the reset button). Since it is good practice anyways, I wanted to set up an udev rule to create an alia...

Re: Simple ULP Blink Example

me not really. I would think just replace the first two commands in my readme (pip/pio ) with a plain esp-idf installation for windows. The rest should be very similar, but I‘m nut sure. Never used esp-idf on windows.

Re: ESP-IDF Version for ESP-WHO samples

The slowness of the arduino sample is gone if I do not use WLAN repeaters. Seems espressifs wifi stack does not like having several stations with the same SSID around? Had similar issues I could not narrow down until now with esp8266 too. Pulled esp-who, that had some minor updates, but still no wor...

Re: ESP-IDF Version for ESP-WHO samples

I read a bit about git submodules and tested a bit further: I changed to esp-idf directory/submodule and did a git log to find all commits mentioning http_server. I checked out commits preceeding those http_server commits one by one and rebuilt: cd esp-idf git checkout <hash> cd <example-dir> make c...

Re: ESP-IDF Version for ESP-WHO samples

Hi Jean-Luc, looks like I have a similar problem. Maybe it helps knowing this is not a one time error. I tried to compile the webserver example like this (changing serial port, adding wlan config and selecting AI-Thinker board in menuconfig): cd git clone --recursive https://github.com/espressif/esp...

ledc_isr_register() does not work for me [solved]

Hi all, I have written a small example to use LEDC to fade in a led. Worked great. Then I wanted to extend this: Enable interrupt on fade end to start a fade out, then again an interrupt to fade in again. This did not work. I tried a lot of things (ISR with IRAM_ATTR or without, use separate Task to...

ULP equivalent for rtc_gpio_init() ? [solved]

Hi ESP32 ULP friends, I wrote a simple ULP blink programm, and it basically works. But my goal was to use the main core just for loading and starting the ULP code, nothing else. Unfortunately the led at GPIO2 stays off if I don't do a rtc_gpio_init(2) in the main core first. Is it not possible to do...

Simple ULP Blink Example

Hi esp32 users, I just started my esp32 ulp journey and found it a bit difficult to get going. One reason was, I come from PlatformIO framework where no ulp integration exists (am I wrong?). And then, because there was no really easy first blink example. So, now that I got it working, I made one ava...
