Raspberry_Pi_Master_for_ESP32_I2C_SLAVE

use Raspberry pi as MASTER of a ESP32 SLAVE on i2c bus

To use ESP32 as slave on i2c bus you have to use ESP32_I2C_Slave c++ 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

to install it use pip:

pip install raspberrypi-esp32-i2c
