Code status:

I started and basically completed initial code last night. It should be enough to have soft power buttons with memory.

RTC is initialized but has no way to set it. A flashing LED akin to a flashing 12:00 on a VCR will exist until I implement a way to set the clock. Even if there was some way to set the RTC, there's no alarms / timers implemented yet.

Backup battery is used to store non-volatile settings related to soft power.

I2C master support isn't implemented yet, but should be a mostly copy-and-paste job. However, there isn't anything to implement yet - every addon is different and I don't have anything in mind. Maybe I'll put something together at Supercon.

Addon GPIO ports are configured as per the provisional GAT standard to set the ID of the addon to 0. This is a weak pulldown on both pins so nothing else is happening. I may implement arbitrary GPIO or a WS LED driver that can be used on this port. Long-term goal would be Corsair iCUE support to control external RGBLED via the PC.


Board fabrication status:

The PCB stackup was rush completed and sent for fab on 20241014. The front sub-boards are half done. The main board is fabricated but SMT assembly has not yet started. I hope there are no delays...
