I am trying to get my teensy 3.1 to communicate with the STN1110 on board the Sparkfun OBD-II UART board (https://www.sparkfun.com/products/9555), but without much (any) luck.
I have communicated with the OBD board with a simple serial connection on my Arduino, but when I hook the board up to the Teensy (serial3 port) I cannot seem to get any serial communication going. I have tried switching the TX/RX wires, just to make sure that that wasn't the case.
I know the OBD likes 5v, but as far as I can read the Teensy is ok with 5v on the RX/TX pins? Any ideas as to what I am missing?
Many thanks in advance
