A simple PCF8574 control

16.04.2021 Changes by: David-2D3FE9

WriteBit method added to allow to write a bit from a parameter source (e.g. from another function).

startI2C will now push the initial value to PCF8574, otherwise the initial value is useless until the first set/reset/invert.

The example received the new method. Because the loop will repeat forever I added a "====>" to the cycle begin in order to make this more visual in serial output The serial output display values in BIN format witch is more readable
