[Video] ESP32 - PCF8574 GPIO Extender

Postby kolban » Sat Mar 04, 2017 7:22 pm

In this video we look at using the PCF8574 to provide additional GPIO pins for reading/writing on our ESP32s. We illustrate by driving a string of LEDs. We also look at a C++ class that can be used to encapsulate the details of driving the IC.
