## 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.
On Windows, you will normally find _SparkFun_u-blox_GNSS_Arduino_Library.h_ in:

Get the GPGGA NMEA sentence using getLatestNMEAGPGGA

basically do whatever you want with this code.
** Please note: this example will not run on Arduino Uno. See https://github.com/sparkfun/SparkFun_u-blox_GNSS_Arduino_Library/blob/main/README.md#memory-usage
This example shows how to turn on/off the NMEA sentences being output over I2C.
It then demonstrates how to use the new getLatestNMEAGPGGA function to retrieve the latest GPGGA message.
getLatestNMEAGPGGA returns immediately - it is not blocking.
