In this video I will show you the challenge in using a module that works over UART, like the GPS module. The challenge is, if you do not continue to constantly read the data from the UART, the buffer fills, overflows, and then you lose data. This means when you go back later to make a read, you will find stale data in the buffer, and incomplete or corrupted NMEA sentences. These can then cause your program to crash. We will explore the problem in this video, and then your assignment will be to rewrite the program to fix this problem. Enjoy!
We are actually pursuing building a GPS Tracker, and this is the gear we will be using in this class:
Raspberry Pi Pico W:
amzn.to/3FA4tqS
Adafruit Ultimate GPS:
amzn.to/4jeRIjj
External Antenna (OPTIONAL):
amzn.to/4myFWTL
Button Battery For Quicker Fix:
amzn.to/3FjoUbH
Breadvolt Power Supply (OPTIONAL):
amzn.to/4kuuJ50
Charging Cable (If You Don’t Have):
amzn.to/3Z0EMGF
Soldering Iron:
amzn.to/3HpZolw
Solder Practice Components:
amzn.to/4mNaEca
Extra Solder:
amzn.to/4kuuDdE
Safety Glasses:
amzn.to/4mwGMjR
