Progress
This week, I made more progress toward writing the boilerplate firmware needed to get the microcontroller to communicate with our various peripherals. This includes another pass at the SPI transaction handling for the display, and a preliminary serial setup for receiving GPS data.
Here’s a screenshot of my newly rewritten function for efficiently updating the display by sending only changed lines:
Pacing
I’m a bit behind schedule in terms of producing our actual prototype board, but I have at least shown the fact that the various hardware we’ve been planning to integrate will work together, which was needed in order for Carson to start designing the board schematic.
Planning
Next week our GPS module should arrive, so I can actually properly do GPS integration rather than sending test data. After that point, I should finally be done with our “breadboard prototype” step, at least in terms of firmware.
