I want to hook the reader Matrix3 want to use the Wiegand Protocol. Is this possible? If to how? Maybe someone has done this before and have an example? Since iButton DS1990A on 1wire is bad.
...a pretty weird protocol... Wiegand Interface Definition and Micro RWD EM4001 “Mag swipe” Decimal Output Version.
Is that what you are talking about?
Seems to be a 500bps protocol... a state-machine in Espruino could implement it with setWatch()'s on two RX connected to the sensor's/reader's TX (and of course two more connections for the communication in the other direction).
Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.
