The ARMmite or ARMexpress can be interfaced to a number of GPS devices. This example uses SparkFun EM-406A. The ARMmite BASIC compiler or the pre-configured ANSI C compiler makes it a snap to integrate serial device to solve your control problem. The first step was adapt the cable for the ARMmite, schematic attached.. This is just a straight through adapter from the 1mm pitch to 0.1inch pitch proto area.
Next was to mount the mating connector on the ARMmite, alligned to the alternate holes
for IO(8) through IO(12), and to make the ground and power connections.
If 30 gauge wire-wrap wire is used there is an alternate place to pick up a regulated 5V
after carefully scraping off the solder mask
(see attached diagram).
The GPS is controlled with the serial commands. The program consists of 2 pieces, an includable basic library and the test program.
For an example of the output view this video clip.
