Python classes to use Raspberry Pi as master i2c on ESP32 using ESP32_i2c_slave library
platformio lib_deps = ESP32 I2C Slave https://github.com/gutierrezps/ESP32_I2C_Slave
because the esp32-arduino framework not allowed you to use ESP32 as i2c slave.
The ESP32 I2C Slave library do the job on 2 ESP32 or Arduino + ESP32 but not with python master on raspberry pi.
So i convert parts of this library to python classes.
To use these classes you must need to install:
pip install adafruit-blinka pip install adafruit-extended-bus
Follow examples to read data from master RPI to slave ESP32: example-read example-write example-slave-side
to install it use pip:
pip install raspberrypi-esp32-i2c
