I2c communication with the PCF8574 parallel i/o by bitbanging from Esp32Forth directly to a pin. All is written in high level Forth, so you can transport this code to other mpus. This way you can convert any of the ESP32 pins into an I2c port. (by Peter Forth) https://www.ti.com/lit/ds/symlink/pcf8574.pdf

This example shows how to drive 2 DC Motors with the L298 board made for arduinos and makers. The short PWM forth code shows how to setup the PWM channels to reverse direction and speed, and speaks for itself. --( note that 5V pin on ESP32 is on purpose NOT connected to the 7.5V line, when you use USB to talk to the ESP32 it will receive the 5Volts from the port. If you connect 2 power supplies you risk damaging the USB port ! )
