I needed to connect a Garmin GPS 18x to the Cortex’s UART port, but I discovered that I would first need to convert the GPSs RS-232 signal to a TTL signal for the UART. I found this board and was wondering if anyone could tell me if this is what I need: SparkFun Transceiver Breakout - MAX3232 - BOB-11189 - SparkFun Electronics
Also, could someone help me figure out which wire would go where on the board? The datasheet that Sparkfun provides isn’t specifically for this board and the labels aren’t very specific.
Both the referenced sparkfun products should work. GPS communication is usually at a pretty low speed (used to be something like 4800 bps) but I’m not familiar with Garmin equipment so that may be different. Interfacing to the cortex using any of the available development options (although most difficult in EasyC) should be pretty easy.
