I have as the title woudl imply the 16 port GPIO USB module. This is my first time working with this product. Tee end goal is to get change notification from IO 0-7 and then after IDing which state changed, read the value present in the ADC for that IO. I am having difficulty quite understanding what the output in the notify string indicated sin relation to which IOs are engaged. For instance the following output was while I had GND => 04 and GND => 00 006F 006E 007F 007F 006F 007F 006F 007F 007F 007F 006F 007F I realize they are hex representations of a binary number, but for instance if I take that first set 006F => 01101111 => 111 How does that state that I had 0 and 4 active? Essentially I need more detail on how those three hex sets break down and what they represent when a notify event comes in.
