Drivers for various ancillary hardware used in reef-pi, based on reef-pi/hal

Introduction

This repository contains a set of drivers for ancillay hardware used in reef-pi project. They are intended to have minimal dependencies (most cases only reef-pi/rpi). These drivers API are not stable, and subjected to change as per reef-pi's requirement.

Currently available drivers

• PWM: PCA9685
• LED Display: HT16k33
• pH probe: Atlas scientific ezo ph circuit
• ph_board: ADS1115 based pH circuits
• ph4502c: ADS1115 based pH circuits
• pico-board: ATSAMD10 pH adapter for the blueAcro Pico board
