Hi , im trying to save dgps values to the datalog ,but it seems that the datalog can only save 2byte int numbers only. The gps values are something like :
38.345564 or 38345564(38.345564*1000000) . Any suggestions ?

Multiply by a constant value that will make each of your values an integer and then you can divide out the constant during the analysis.

If the integer is too big to fit, split it up. So 348968598940 becomes 348968 and 598940.
