A library for PCF8574A (8-bit) and PCF8575 (16-bit) I2C I/O expanders used on a custom PCB that provide input read (State ON 4 to 30V) and relay output.
EasyIO simplifies the control of PCF8574A and PCF8575 expanders using active-LOW output logic. It prevents chip damage and short circuits by automatically enforcing input bits LOW during operations, avoiding incorrect pin state conflicts.
