Overview

The SPIO-4 Digital Controller board is used to read registers, write registers, and capture data from various TI's Sensor AFE and other signal path products. The device evaluation board (for example: LMP90100EB) should be equipped with the GPSI-16 or GPSI-32 header to connect to the SPIO-4 board, which contains a USB port to connect to the PC with a Sensor AFE Development Platform Software.

Each device has a separate Development Platform Software with a common look and feel. The software enables design engineers to quickly evaluate each Sensor AFE or other signal path product. The driver for the SPIO-4 board and instructions to download the driver is included in each software folder.
