Embedded Rust on Espressif training material.

Unified library for M5Stack series

µCNC - Universal CNC firmware for microcontrollers

This is an ESP32 / ESP8266 WiFi Connection Manager with fallback web configuration portal. Use this library for configuring ESP32 (including ESP32-S2 and ESP32-C3), ESP8266 modules' WiFi, etc. Credentials at runtime. You can also specify static DNS servers, personalized HostName, fixed or random AP WiFi channel. With examples supporting ArduinoJson

Beryllium OS, a unix-like operating system for CircuitPython powered microcontrollers. (Formerly known as ljinux)

This is an ESP32 (including ESP32-S2 and ESP32-C3) / ESP8266 WiFi Connection Manager, using ESPAsyncWebServer, with fallback web configuration portal. Use this library for configuring ESP32, ESP8266 modules' WiFi, etc. Credentials at runtime. You can also specify static DNS servers, personalized HostName, fixed or random AP WiFi channel. With examples supporting ArduinoJson 6.0.0+ as well as 5.13.5- . Using AsyncDNSServer instead of DNSServer now.

This library enables you to use Interrupt from Hardware Timers on an ESP32-based board. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based timers. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks.

ESP32 PWM, Servo, Easing and Tone. Smart GPIO pin management and advanced control features.

A compact hardware device for transmitting WSPR messages based on the SI5351 clock generator, using GPS for transmission timing synchronization and automatic QTH locator calculation.

Super Mini ESP32-C3 sketches

A streaming library for Arduino esp32 with a vs1053 mp3/aac/ogg decoder. Plays http, https and chunked streams. Stream metadata is parsed. Also plays ogg and mp3 from sdcard.

A display library: implemented purely in Micropython. 纯 Micropython 实现的显示库

Go CLI and library for flashing firmware to Espressif ESP8266 and ESP32-family microcontrollers

Replace Tuya device wifi module with ESP32-C3

Library using AsyncWebServer to configure MultiWiFi/Credentials at runtime for ESP32 (including ESP32-S2 and ESP32-C3) and ESP8266 boards. You can also specify DHCP HostName, static AP and STA IP. Use much less memory compared to full-fledge WiFiManager. Config Portal will be auto-adjusted to match the number of dynamic custom parameters. Optional default Credentials to be autoloaded into Config Portal to use or change instead of manually input. Credentials are saved in LittleFS, SPIFFS or EEPROM. New powerful-yet-simple-to-use feature to enable adding dynamic custom parameters from sketch and input using the same Config Portal. Double or MultiDetectDetector as well as Virtual Switches feature permits entering Config Portal as requested.

ESP_DoubleResetDetector is a library for the ESP32/ESP8266 Arduino platform to enable trigger configure mode by resetting twice.

Firmware for ESP32-C6 and ESP32-C3 allowing eBUS communication for ebusd (https://github.com/john30/ebusd) and including micro-ebusd option (https://adapter.ebusd.eu/v5-c6/uebusd.en.html)

IoT enabled HDMI mux

A thread-safe MQTT client for Arduino ESP32xx, based on ESP-IDF MQTT component. Work with the latest ESP32 Arduino Core 3.x and ESP-IDF 5.x.

ESP32 application to act as an IO Extender for another ESP.

Polyglot examples for the 01Space ESP32-C3FH4-RGB board

This library enables you to use 1 Hardware Timer on ESP32-based board to control 16 or more servo motors. Now supporting ESP32, ESP32_S2, ESP32_S3, ESP32_C3-based boards. Tested OK with ESP32 core v2.0.5

SparkMiner: A high-performance, open-source ESP32 Bitcoin solo miner. By combining the usability of NerdMinerV2 with the raw speed of BitsyMiner's pipelined assembly, SparkMiner delivers optimized hashrates (~725+ KH/s) to challenge paid firmware alternatives.

ESP32-C3 act as USB to serial UART interface like FT232R or CP210x

PCB with ESP32 and CAN bus. For controlling CAN-devices like heatpumps via ESPHome

This library enables you to use Interrupt from Hardware Timers on an ESP32, ESP32_S2 or ESP32_C3-based board to create and output PWM to pins. It now supports 16 ISR-based synchronized PWM channels, while consuming only 1 Hardware Timer. PWM interval can be very long (uint32_t millisecs). The most important feature is they're ISR-based PWM channels. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks. These hardware PWM channels, using interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using millis() or micros(). That's necessary if you need to measure some data requiring better accuracy.
