Getting time and date using u-blox commands

License: MIT. See license file for more information but you can
|
|
basically do whatever you want with this code.
|
|
|
|
This example shows how to use the Millisecond and Nanosecond output as well as increase the
|
|
I2C speed (100 to 400kHz), and serial output (115200 to 500kbps).
|
|
|
|
Note: you will need to set your Serial Monitor to 500000 Baud to see the output
|
|
|
|
Leave NMEA parsing behind. Now you can simply ask the module for the datums you want!
|
|
|
|
Feel like supporting open source hardware?
|
|
Buy a board from SparkFun!
|

ZED-F9P RTK2: https://www.sparkfun.com/products/15136
|
|
NEO-M8P RTK: https://www.sparkfun.com/products/15005
|
|
SAM-M8Q: https://www.sparkfun.com/products/15106
|
|
|
|
Hardware Connections:
|
|
Plug a Qwiic cable into the GNSS and a BlackBoard
|
|
If you don't have a platform with a Qwiic connection use the SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)
|
|
Open the serial monitor at 115200 baud to see the output
