Description: Python driver for PCF8574 8bit IO Expander board
        Developed for the Raspberry Pi, requires the python-smbus2 package to access the I2C bus.
        
        Tested on raspberry pi 3b plus with two PCF8574 boards.
        
        
        First install smbus2 using:
        pip install smbus2 
        
        
        
        Usage Example:
        
        import pcf8574_io
        
        # you can use up to 8 PCF8574 boards 0x20 and 0x21 are the I2C addresses
        p1 = pcf8574_io.PCF(0x20)
        p2 = pcf8574_io.PCF(0x21)
        
        # p0 to p7 are the pins name
        # INPUT or OUTPUT is the mode
        p1.pin_mode("p0", "INPUT")
        print(p1.digital_read("p0"))
        
        # you can write and read the output pins
        # use HIGH or LOW to set the pin HIGH is +3.3v LOW is 0v
        p1.pin_mode("p4", "OUTPUT")
        p1.digital_write("p4", "HIGH")
        print(p1.digital_read("p4"))
        
        # you can read and write up to 8 boards at the same time just make sure you ech board has a different address
        p2.pin_mode("p7", "OUTPUT")
        p2.digital_write("p7", "LOW")
        print(p2.digital_read("p7"))
