Rohm / Mbed OS rohm-tileshield-6sensor-demo

Demo application of reading 6 different sensors and outputting values on UART. This demo can be used with Rohm tileshield using tiles for BH1726, BD1020, RPR0521, BH1745, ML8511 and BD7411. Developed and tested using Renesas GR-Peach -board.

Dependencies:   rohm-bh1726 rohm-bh1745 rohm-rpr0521 rohm-sensor-hal

Fork of rohm-bd7411g-hello by Rohm
