Displaying four different patterns on 8 LEDs

Описание: 8 LEDs are connected to a microcontroller. An 8-bit "receivedData" variable is hard-coded on the microcontroller. The value of the upper 4 bits of receivedData determine which of 4 patterns is displayed on the LEDs. For this video, SPI is being used to update the upper 4 bits of receivedData in order to show all available patterns.
