7 segment prototype
board for figuring out how to drive them. These are cheap 0.8"
displays from eBay marked 8021AS. They're common cathode but there are
separate anode and cathode pins for each digit, so they operate like two
single digit displays in one package.A 240 FPS slow-mo video and a
slowed down scanning rate of 10ms per digit shows how each digit is
updated separately.
The boards.Testing the LED output. I think this
pattern is a 7 segment sequence from the breadboard prototype.Testing everything now. With all six
columns scanning there is some flicker in person but it's not that
noticeable.The project finished and working with
Assetto Corsa. I think it reacts slightly faster than the tachometer on
the TV. BTW, who else remembers Sega's F355 Challenge?
