Progress with XIAO Expansion Board

I took off work yesterday and goofed around most of the day coding on my ESP32C6 with the XIAO Expansion Board, mostly reintroducing myself to C programming on in the Arduino IDE and rewritting my little clock app in C. This time, i’m leveraging the RTC capability tho and ordered a coincell battery for the board.

Of course, I spent time shopping for parts and went through my inventory, identifying parts and organizing things. Ok, “organizing” is a generous term. I also purchased a bunch of odds and ends. Nothing too exciting, but I am a little stoked about a linear power supply that is arriving this weekend.

This video shows the clock in action and the second and minute bars updating as the minutes turn over. Nothing to blog home about here. lol.

An odd thing happened when I tried to introduce functionality for the onboard buzzer. The code uploaded successfully, but the display stopped working. I believe it was set to communicate on D06, but something about initializing that pin, deactivated the display – or at least that’s what it seemed to be. That will be a future investigation. Regardless, I feel there is nothing on this board that is too complex to wire up discretely. It feels like anything I develop on here can easily be ported over to another ESP32 project. Very cool.
