* GPS Setup app, hughbarney AT googlemail DOT com
|
|
* With thanks to Gordon Williams for support and advice
|
|
*
|
|
* UBLOX power modes:
|
|
* SuperE - will provide updates every second and consume 35mA, 75mA with LCD on
|
|
* PSMOO - will sleep for update time and consume around 7mA during that period
|
|
* after acquiring satelite fixes the GPS will settle into a cycle of
|
|
* obtaining fix, sleeping for update seconds, wake up, get fix and sleep.
|
|
*
|
|
* See README file for more details
