Hi Andy, thank you for the notes, I am working on fixing them. You have mentioned, that it seems like the driver which should be generic provides specific functionality. AFAIK, the Wiegand protocol does not define the payload length of messages. Most devices use one of the three formats I have implemented - 26, 36 and 37-bits. If I understand you right, the Wiegand GPIO bit-banged driver should allow one to send messages of any length and it will be up to a device driver to make sure the correct message length is used. Is this the correct approach? With regards, Martin
