Hello,
I found this adapter module to extend my GPIOs (Infinity Cascade GPIO Expansion IO Extend Adapter Module http://www.sainsmart.com/sainsmart-infi ... berry.html ) and also in this URL I found a simple document with example python code.
But I cannot find any help/sample code to connect four same board, to use 128+ GPIO ports.
I need about 100+ gpio ports indeed, and I want to connect four boards together.
I need to a document or sample code to help me about addressing in my code.
