Since 0.3.1 the **digitalWrite(pin, value)** is optimized.
If a pin is not changed it will not be written again to save time.

#### REV D - June 2022
The I2C IO expander MCP23017 has changed according to the new data sheet. It is now a 14/16-bit IO expander.
The pins GPA7 and GPB7 have lost their input mode, output mode still works.
