This repository provides a Python 3 interface between user application and KEL USB-I2C interface protocol. See files inside usbi2c directory.
Additionally this repository provides the following examples:
- I2C search algorithm
- ADS1115 16-bit ADC, address 0x48 (includes 10k pull-ups, ADDR = GND and VDD = 5V)
- AT24C02 EEPROM, address 0x50 (YL-90 includes 10k pull-ups and VCC = 5V)
- BH1750 ambient light sensor, address 0x23 (GY-302 includes 10k pull-ups, floating ADDR and VCC = 5V)
- BMP180 temperature and pressure sensor, address 0x77 (GY-68 includes 4k7 pull-ups and VIN = 5V)
- PCF8574 (I2C LCD version 1), address 0x27 (black PCB no text, includes 4k7 pull-ups and VCC = 5V)
- SHT21 temperature and humidity sensor, address 0x40 (GY-21 includes 10k pull-ups)
- SHT3X temperature and humidity sensor, address 0x44
A pyserial package is needed for Python 3 on Windows. The package could be installed by executing pip install pyserial on Windows command line.
In examples, string /dev/ttyACM0 must be changed to reflect serial (COM) port where USB-I2C interface is attached to. Look at Device Manager.
On Debian based operating system a python3-serial package is needed.
