7 segment display controlled by simple SPI interface
I picked up some cheap 4 digit 7 segment displays over on eBay for $10 + shipping. They Include a SPI PT6961 driver chip built in that deals with PWM and Multiplexing, saves on microcontroller ports & current limiting resistors. Figured someone here may have a use for them!
