help us! Need to read values from picaxe digital inputs for Garmin GPS
May 13, 2009
We have a Garmin 16 HVS datasheet
and a Picaxe 28x1
We have wired the 2 output wires for data out from the Garmin unit to the digital inputs on the Picaxe board. Can anyone provide some commands or code snippet that I can use to read what the values from the digital inputs are? I have looked over the picaxe manuals but didn't see any specific commands for getting this data. We are hoping that the GPS output can be displayed in a text format which would let us parse and do what we will with it. Does anyone know if this sounds possible or do we need some other device that can interface with the Garmin?
Basically...the end result is a GPS enabled RC car which is powered only by the Picaxe to control GPS coordinates, navigation, and servo control.
Really, the first step we need help with is just how to properly read the values given from the digital inputs.
