Remi Beges / Mbed 2 deprecated telemetry_sensors_demo

A demo on NXP KL25Z of the telemetry library to publish some sensor data that can be read/plotted on the computer using pytelemetrycli (https://github.com/Overdrivr/pytelemetrycli) Published data: "touch" -> capacitive slider output value "acc:x" -> x channel of the accelerometer "acc:y" -> y channel "acc:z" -> z channel

Dependencies:   BufferedSerial MMA8451Q mbed telemetry tsi_sensor

Overdrivr 1:b63db8e76533 9 Example of the 'Telemetry' library, a portable communication library for embedded devices.
Overdrivr 1:b63db8e76533 10
Overdrivr 1:b63db8e76533 11 This code fetches all the data from the KL25Z bord and publishes it on different topics :
Overdrivr 1:b63db8e76533 12
Overdrivr 1:b63db8e76533 13 The available data is the following :
Overdrivr 1:b63db8e76533 14 * Accelerometer X
Overdrivr 1:b63db8e76533 15 * Accelerometer Y
Overdrivr 1:b63db8e76533 16 * Accelerometer Z
Overdrivr 1:b63db8e76533 17 * Capacitive slider
Overdrivr 1:b63db8e76533 18
Overdrivr 1:b63db8e76533 19 You can use the Pytelemetry Command Line Interface to open plots, visualize the received data,
Overdrivr 1:b63db8e76533 20 and communicate with the car.
