2.2 Setup

LP5899EVM is the connectivity IC between MCU and LP589x Family LED Driver. This section provides the guidance to use LP5899EVM to control LP5891Q1EVM by SPI.

Following the suggested jumper setting, the board can be evaluated by USB power directly and does not need an external power supply. Single LP5891EVM can be quickly set up and tested by following these steps:

  1. Following the jumper setting in Figure 2-1 and Figure 2-2 .
