I’m using the SARA AFF 412 to develop the code for a custom PCB.
On that PCB I’m using a SAMD21 as well in combination with the Ublox M8Q GPS module.
For this project, I’m not able to use the Arduino libraries or setup for communication across I2C and SPI. Furthermore the entire code will be written in normal C.
I’ve tried multiple configurations to connect the GPS module to the MCU but so far I haven’t had any success yet.
I used the datasheet from microchip as well as Ublox for all the registers and addresses, but so far I haven’t been able to get a solid connection going.
I’m monitoring the outputs on a logic analyzer.
Does anybody have any experience using these methods and if so an example I can take a look at?
