Getting Started with Rohm SensorShield-EVK-001

This example demonstrates how to use the SensorShield-EVK-001 component with multiple sensors. those measured values, which received through a serial connection from a mbed board, are printed out in a terminal software window.

Setup

The SensorShield-EVK-001 is plugged on top of a mbed board and a serial connection should be set up between the mbed board and PC with the following parameters:

baud rate: 115200
data: 8 bit
parity: none
stop: 1bit
flow control: none
