Top 23 C esp-idf Projects

How do you have the adc wired to the esp? Your call to SPI.begin() with no parameters means the library will use default gpio numbers. The defaults vary by board type. See https://github.com/espressif/arduino-esp32/blob/master/libraries/SPI/src/SPI.cpp lines 53-67

Project mention: Is the esp-idf-lib by UncleRus a reliable component to use for commercial products? | reddit.com/r/esp32 | 2021-07-01
My first idea to solve this was to create my component which implements a mutex to access each I2C bus. Now, when I was searching github for previous implementations, I saw this repo https://github.com/UncleRus/esp-idf-lib. Not only does it have the solution for I2C it also has components for some of the sensors I am using.

Project mention: Programmer advice sought: My struggles to use an ESP32 to measure WiFi internet speed. | reddit.com/r/esp32 | 2021-05-04
My understanding is that in real-world practical tests of the ESP32 people are seeing more like 10-30Mbps. (Sources: https://github.com/martin-ger/esp32_nat ... erformance, https://serverkernel.com/how-to-turn-es ... -repeater/, https://www.reddit.com/r/esp32/comments ... le_seeing/). As long as I can test that my network is performing at least 10Mbps, then I'm happy.

Have a look at Homepoint, which you can run on an ESP32 with a display, such as the M5Stack Core. I have created something similar with ESPHome, and I'm running this as a dashboard showing the value of a couple of sensors at home. ESPHome on the M5Stack Core makes for a lot of possibilities, see https://koen.vervloesem.eu/blog/you-can-now-use-the-m5stack-core-in-esphome/ for how to use it.

esp32-wifi-manager
Captive Portal for ESP32 that can connect to a saved wireless network or start an access point where you can connect to existing wifis.
Project mention: How can I implement a WiFi manager for ESP8266 using the ESP8266 RTOS SDK? Are there repositories that implement this already? | reddit.com/r/esp8266 | 2021-08-24There's a WiFi Manager Library for ESP-IDF (ESP32) I am expecting it to work with ESP8266 with changes respective to RTOS-SDK. It's still a work in progress for me. You can try as well. Here is the link to esp-idf WiFi Manager library by tonyp7 https://github.com/tonyp7/esp32-wifi-manager

I would really like to see more work on improving the use of Nim for programming microcontrollers. I stumbled on to https://github.com/elcritch/nesper recently and it looks neat, but I had issues getting my code to compile. Improved support for other MCUs like the esp8266 and atmega32u4 would be really cool and useful. It would be nice to have Nim as a higher level alternative to micropython or lua in the embedded world (your only other real alternatives being C/C++ or Rust).
I also found this https://disconnected.systems/blog/nim-on-adruino

Doesn't seem like you read his post really. Your assumptions were wrong as well. Anyway you can use them as a USB device, but their performance isn't great. One way is: https://github.com/tobozo/ESP32-USB-Soft-Host

Yeah, but it involves a lot of development. I made this a few months back : https://github.com/ugomeda/esp32-epaper-display
I'm working on a more "user-friendly" version :)

Gesture-Detecting-Macro-Keyboard
Glorified Bluetooth macro keyboard with machine learning (TensorFlow Lite for Microcontrollers) running on an ESP32.

This code is test code and has no license info or copyright headers, plus it's basically throwaway right now, so if you do mess with it, don't fork it. I'll be rolling changes into https://github.com/codewitch-honey-crisis/gfx_demo when I solve this issue.

Oh, I was looking at your project as well. Do you have any plans to migrate hagl_esp_mipi to esp-idf v4 (to use idf.py instead of make)?

yeah we're using the esp32 too, works great. checkout https://github.com/supergreenlab/SuperGreenOSBoilerplate it's a boilerplate that does most of the boring setup job, also generates a clean admin interface:) The SGLOS is based on that.
