I managed to get the LS20031 to work with an UNO R3 board. Now, the next challenge is to repeat that with an RPI2. Most tutorials I’ve found talk about going through a USB interface. However, I wanted to ‘talk’ to the GPS module when it’s connected DIRECTLY to the RPI GPIO. ANyone tried this and could shed some light?
Raspberry Pi has GPIO library that you can use to access the pins. There’s a Python library and also some for C.
