Hi friend, I have Arduino Uno and MDB connector from Vending Machine. How to connected it, do you have schema / wiring of diagram to make your code works?

mkrasselt1 commented 1 year ago

just take a look at the mdb specsheet - there is an example with two optocouplers. connect them to the rx and tx pins of the slave device

Made a pull-request with a kicad schematic made in about an hour.

@mkrasselt1 I've sent you an invitation to be a contributor (because github won't let me merge the branch myself). And since you were more active on this repository through the years than myself, it would probably be better anyway.

@LanguidSmartass Yes thank you, i might work on this a little from time to time. But @tomeroto https://github.com/LanguidSmartass/mdb-arduino-cashless/blob/master/mdb-interface.kicad_sch this is the file he is talking about - open in kicad latest version :)
