Intelligent 7-Segment display

An intelligent 7-Segment display based on Padauk MCU:

I elected to use a PADAUK PFS154-S16 as microcontroller for each segment. This device has flash memory and sufficient I/O to control a 7 segment display without multiplexing. The cost is only $0.07, so it is cheaper than, for example, using multiple WS2811 instead. The data input pin is connected to PA0, which allows using a pin change interrupt to detect incoming transmissions. Data out is PA6, while PB0-PB7 are used to control the display.
