Hi all, my idea is to implement the driver for using this GPIO extender, based on 74HC595 chip, (https://www.sainsmart.com/raspberry-pi/sainsmart-infinity-cascade-gpio-expansion-io-extend-adapter-module-for-raspberry.html) with webiopi REST interface. The most important feature of this product is the easy way to install it on raspberry in cascade mode.
How can I implement it? Can you help me?
You can find the docs attached.
Thank you very much for the support! Regards, Mauro
