it is a microprocessor. The main use of it is to take care of the processing
of NMEA signals. The device Im building is used mainly for sensor and
Sorry for this late reply. I didn't know that somebody was doing the same
crazy things as me.
I have developed a hand-held GPS with a MSP430 F 169. So in your case,
you could use exactly the same design since the F149 is 100% pin
Look at that:
Now I have a thinner GPS module that can be used with the same
design in case you want to save a few grams.
Beside this, there is plenty of room for the MCU to perform other
operations since the only thing it does is reading the GPS and parsing
the NMEA data. As you apparently need other measurements, that may
be a good off-the-shelf solution for you.
Well, that's about it. If you have any question, please post a question
here or send me a private message.
