esp32_isr_servo

This library enables you to use 1 Hardware Timer on an 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 v2.0.3

esp32_mcp23x17_freertos

A small sample program to create FreeRTOS tasks on an ESP32 (Arduino Framework using PlatformIO) using the Adafruit MCP23017 Arduino Library. The programm creates RTOS tasks to keep Pins on an MCP23017 I/O Expander to a defined state for a certain amount of time.

esp32_mgo_tec

This is Arduino core for the ESP32 library Package by mgo-tec.

esp32_net_restart

Drive an output pin high when internet in not available to reset the router

esp32_new_timerinterrupt

This library enables you to use Interrupt from Hardware Timers on an ESP32, ESP32_S2 or ESP32_C3-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. These hardware timers, 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.

esp32_pca9555_isr

this project just simply shows how to drive I2C interrupt function(based on esp32 platform with IC pca9555).
