flirbleoss / Projector Screen Controller - History

UART size fix

* Off-by-one in one comparison

Basic UART handling

* Circular buffers for TX and RX, for UART1 and UART2
* Wiring for TX and RX on UART interrupts
* Basic primitives for writing to and reading from buffers
* Not tested yet

Skeleton firmware

* Basic hardware initialization
* Template for interrupt handling
* Details over timers, etc still needs to be worked out

Add nominal LED R values; ground plane tweaks; first board spin

Update fuse footprint, add more 3d models, update TODO

Update README, add ground planes, adjust clearance

* Update the README with background and a 3d preview image.
* Add ground planes to front and back of logic section; add an earth plane on
back of line voltage section.
* Check clearances around line voltage input section.
* Change mounting holes to a standard type with plated flange.
