esp32-pokit's Introduction

M5StickC plus ESP32 client for Pokit Pro

Pokit Pro multimeter client on M5StickC plus(ESP-PICO-D4) via BLE, base on Arduino.

Features

Display all Pokit Pro's multimeter values, use button A to switch measurement type, with auto range
Auto range display
Auto follow Pokit Pro's mode switch(Voltage,Resistance/mA,Amperage)
Cycle through brightness(button B)
Display M5 and Pokit's battery voltage
Low power consumption (~35mA, 3.5hours battery life on M5StickC plus)

Get started

M5StickC plus hardware
Download Arduino IDE
Install M5StickC plus board and library:
- https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/arduino/package_m5stack_index.json
Compile and upload, that's it!

Support

For ESP32

Currently only support M5StickC plus. However, the code, including display drawing part may work on any M5 product. Just need to import corresponding headers and adjust those text arragnement. Also the BLE part of code should also work on any ESP32. All display-related code is inside display.cpp. You can adapt for your display hardware easily.

For Pokit

Currently only support Pokit Pro. However, it should works with Pokit meter with only modifiying the BLE Service UUID.

Roadmap

Fix the mode switch. Currently missing amp measurement when handle is in middle.
Compile Arduino core with ESP32's DFS(dynamic frequency scaling) for M5 series.
Create library for ESP32.
