Library to use i2c pcf8574 IC with arduino, esp8266 and esp32.
This IC can control (until 8) digital devices like button or led with 2 only pins.
Here I explain the manage of multiple rotary encoder.
Library to use i2c pcf8575 IC with arduino and esp8266.
This IC can control (until 16) digital devices like button or led with 2 only pins.
Can read and write digital value with only 2 wire (perfect for ESP-01).
I try to simplify the use of this IC, with a minimal set of operation.
I write this guide because I think It’s helpful have a starter tutorial to milling PCB in a very simple way and low budget.
Now create GCode file for the CNC
I’m going to explain a connection schema for a character display i2c adapter.
