ESP32 project with lua interpreter and bindings for sensor libraries

This project has libraries for SunFounder sensors; this libraries have lua bindings and could be used from lua.

List of libs

• i2c
  • .init() - initialize i2c
• bmp180
  • .get() - return values; ex. temperature, pressure = bmp180.get()
• buzzer
  • .play() - play sound in passive buzzer
• rgb
  • .set(int,int,int) - saves values and turns on rgb
  • .on() - turns on rgb with saved values
  • .off() - turns off the rgb
• lcd
  • .init() - initialize lcd
  • .set(int,int) - pointer coordinates
  • .write(string) - string to print
• gas
  • .get() - return digital state value, and analog ppm value; ex. state, value = gas.get()
• eddystone
  • .init() - initialize bluetooth beacon settings
  • .start(callback) - start scanning, return found devices in callback funcion as a table
  • .share() - start advertising of a new URL eddytone beacon
  • .stop() - stop scanning

table for eddystone devices contains:

• type

Usage example

lua> i2c = require "i2c"
lua> lcd = require "lcd"
lua> i2c.init()
lua> lcd.init()
lua> lcd.set(0,0)
lua> lcd.write("hello world")
