GPIO access and interrupt detection with Node.js

Fast GPIO, PWM, servo control, state change notification and interrupt handling with Node.js on the Raspberry Pi

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…

A low-level Node.js binding for the Linux epoll API

Example codes using sdcc to target STM8S MCUs.

A RISC-V bare metal example

This library enables you to use Interrupt from Hardware Timers on supported Arduino boards such as AVR, ESP8266, ESP32, SAMD, SAM DUE, nRF52, Teensy, etc. 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 softw…

Arduino Library to access the MCP7940M, MCP7940N and MCP7940x Real-Time chips

This library enables you to use Interrupt from Hardware Timers on an SAMD-based board. These SAMD 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 mandatory if you …

This library enables you to use Interrupt from Hardware Timers on RP2040-based boards such as RASPBERRY_PI_PICO. These RPI_PICO_TimerInterrupt 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 m…

This library enables you to use Interrupt from Hardware Timers on an STM32F/L/H/G/WB/MP1-based board. These STM32F/L/H/G/WB/MP1 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 micr…

Handle TrapFrame across kernel and user space on multiple ISAs.

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

Single Board Computer like Raspberry, Arduino, ASUS etc.

This library enables you to use RTC from RP2040-based boards such as Nano_RP2040_Connect, RASPBERRY_PI_PICO. This RP2040-based RTC, using Interrupt, has no battery backup. Time will be lost when powered down. To need NTP-client to update RTC every start-up.

A bare minimum but really fast and simple stepper library for Arduino.

문c 블로그 with ARM64 Linux Kernel 5.x

This library enables you to use Interrupt from Hardware Timers on an nRF52-based board. These nRF52 Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise than other software timers using millis() or micros(). Now supports `Sparkfun Pro nRF52840 Mini`
