3.5. Evaluating the LMP91051 without the SPIO-4 Board
The SPIO-4 digital controller board is used to generate the SPI signals to communicate to the LMP91051.
Without the SPIO-4 board, the Sensor AFE software for the LMP91051 cannot be used to capture and
analyze data from the LMP91051EVM.
If the SPIO-4 board is not available but LMP91051 evaluation is desirable, then connect your own SPI
signals to J1 of the LMP91051EVM as seen below. Reference the LMP91051 datasheet for appropriate
SPI timing diagrams. Source LMP91051 VDD with an external power supply per previous section.

Installing the Sensor AFE Software
Each Sensor AFE product will have its own software. To access the Sensor AFE software for LMP91051,
follow the steps below.
1. Getting the Zip Files
a. You can find the latest downloadable Sensor AFE software at
ti.com/sensorafe
b. Download the zip file onto your local hard drive. Unzip this folder.
2. Installing the Driver - skip this step if you don’t have the LMP91051EVM and SPIO4 digital controller
board.
