## Memory Usage
|

|
||||
The u-blox GNSS library has grown considerably over the years and v2.0.8 came very close to completely filling the program memory on platforms like the ATmega328 (Arduino Uno).
|
||||
If you want to reduce the amount of memory used by the library, you can edit the header file (_SparkFun_u-blox_GNSS_Arduino_Library.h_) and uncomment line 60:
|
||||
The u-blox GNSS library has grown considerably over the years and now exceeds the available program memory on platforms like the ATmega328 (Arduino Uno).
|
||||
If you want to reduce the amount of memory used by the library, you can edit the header file (_SparkFun_u-blox_GNSS_Arduino_Library.h_) and uncomment lines 60 and 63:
|
||||
|
||||
```
|
||||
#define SFE_UBLOX_REDUCED_PROG_MEM // Uncommenting this line will delete the minor debug messages to save memory
|
||||
```
|
||||
|
||||
Doing this will save approximately 15% of the program memory used by the library. From v2.0.18 of the library, the debug messages are automatically deleted on ARDUINO_AVR_UNO platforms. For other platforms, you will need to uncomment that line manually.
|
||||
```
|
||||
#define SFE_UBLOX_DISABLE_AUTO_NMEA // Uncommenting this line will disable auto-NMEA support to save memory
|
||||
```
|
||||
|
||||
**Please note:** the debug messages are automatically deleted and auto-NMEA support is automatically disabled on ARDUINO_AVR_UNO platforms. For other platforms, you will need to uncomment those lines manually.

||||

getLatestNMEAGPGGA returns immediately - it is not blocking.
