2-sided pov toy

A double sided MiniPOV for displaying text in a bike wheel.
I wanted to enhance the minpov to display text on both sides of the bike wheel. i chose to use microchip’s pic because they sold a cheap programmer and i had lady ada’s working source code. the biggest challenge with displaying text on both sides of the wheel each side needs to read from a different end of the string. if you’re displaying ABC the left side needs to start at C and the right side needs to start at A. that meant i needed 16 outputs, four more than the 16f630 has. to work around this i used an 8-bit addressable latch for each side.
