Introduction
1.1
Description
The evaluation board is powered with external power supplies. An external device capable of providing
clock, data, latch, and blank signals also controls the EVM. This is done with an SPI-compatible serial
interface on a microcontroller or through a function generator. Connect different LEDs to the evaluation
board through the output connector.
