Short Content: The abstract elaboration in WiTadows in the CE embedded system, realizes GPS and the PDA correspondence method using the serial port. First, introduced that the GPS signal the data format, and carries on the description to system's software and hardware environment and the serial communication. Finally, designs the GPS signal processing module, explained in detail how to use the embedded program language development serial port signal procedure, and gives the concrete step and the part realizes the code.Key word GPS ...
