There is popular LEDs & buttons board (tm1638). I wonder, has anyone ported tm1638 to PSoC?
I did not knew this IC, how are you planning to implement it? UDBs, Verilog, C?
I was hoping somebody already did it. There is nothing special: bidirectional SPI port, several libraries available on github (Arduino, Stellaris and MSP430, but nothing for PSoC). Can be good input device. Priced about $2 shipped.
