Where to save data coming from a GPS device? RAM,EEPRM or Flash memory?

Amilcar Peres

I am using a P89c51 base microcontroller and I need to store data coming from a GPS device.

Questions:
1.Is it possible to save the data coming from the GPS,in the 64k Flash memory?
For example 32kytes for the code and 32kbytes to store the data?How?

    Hi Amil,Where to store the data?
    You must store insight your RAM
    1. The life cycle of your EEPROM or Flash is limited may be 100K or 1M
    2. You need some times to write your data to EEPROM or Flash,
    3. Receiving GPS under ISR, So you may be face some timinng probelm,

    The best way you store your data into RAM and periodically update to PC,

    Other way you can save the data only if you chnage your position simply if you received differnt coordinate from GPS
