Why do we need this NRF52_ISR_Servo library

Features

This library enables you to use 1 Hardware PWM module on an nRF52-based board to control up to 16 independent servo motors.

Currently supported Boards

  • AdaFruit Feather nRF52832, nRF52840 Express, BlueFruit Sense, Itsy-Bitsy nRF52840 Express, Metro nRF52840 Express, NINA_B302_ublox, NINA_B112_ublox etc.

Changelog

Releases v1.0.0

  1. Basic 16 ISR-based servo controllers using 1 hardware PWM module for nRF52-based board
  2. Support to both nRF52832 and nRF52840

Examples:

  1. nRF52_MultipleRandomServos
  2. nRF52_MultipleServos

Example nRF52_MultipleRandomServos Adafruit NRF52840_FEATHER

The following is the sample terminal output when running example nRF52_MultipleRandomServos on Adafruit NRF52840_FEATHER to demonstrate how to control multiple Servos.
