Arduino Library to approach PCA9555 I2C expander with digitalRead, digitalWrite and pinMode functions.
- a) Just download the zip file
- b) move PCA9555_LIB to the Users Arduino library (usually My documents\Arduino\Libraries)
- c) Create a new sketch and copy the example file into your sketch
- d) Compile, download and done.
- pinMode() same as standard Arduino
- digitalRead() same as Arduino
- digitalWrite() same as Arduino
The code supports either pinnumbers 0 - 15 or ED0 - ED15. This to stay more or less in sync with Arduino.
