Sample Android Things Application with multiple sensors using UPM
2+
-----------------------------------------------------------------
3+
4+
This example demonstrates an application with multiple sensors using I2c and GPIO connection using
5+
UPM.
6+
7+
Pre-Requisites:
8+
---------------
9+
Use of the Grove Kit (for Joule or Edison) makes this easy. See the following links for getting
10+
a starter kit.
11+
12+
* https://www.seeedstudio.com/Grove-Maker-Kit-for-Intel-Joule-p-2796.html
13+
* https://www.seeedstudio.com/Grove-Starter-Kit-V3-p-1855.html
14+
15+
16+
You will need:
17+
18+
1. Android Things compatible board.
19+
2. Grove header or Breakout board.
20+
3. Joule Shield.
21+
4. A Grove touch sensor.
22+
5. A Grove push button.
23+
6. A JHD1313m1 LCD display (it's in the grove kit).
24+
7. A TMP006 Temperature Sensor.
25+
8. 3 LEDs. One of each color. Red LED, Blue LED and Green LED.
26+
27+
28+
Build and install:
29+
------------------
30+
31+
On Android Studio, select the "multisensor" module in select box by the "Run" button
32+
and then click on the "Run" button.
33+
34+
35+
Changing the GPIO and I2C bus
36+
-----------------------------
37+
This example uses a GPIO (digital input) to read the state of a touch sensor, a GPIO (digital input)
38+
to read the state of a button, 3 GPIOs (digital output) to light LEDs (Red, Green and Blue).
39+
An I2C temperature sensor to get the ambient temperature and an I2c
40+
jhd1313m1 LCD display to display the temperature values.connected via the shield to the sensors.
41+
42+
The I2C and GPIO line to be used is specified in the strings.xml file (src/res/values directory).

74+
75+
The code will automatically determine the board type being run on (modify BoardDefaults.java
76+
in the driver library to add another board) and select a string from this file for the GPIO line.
77+
These strings are programmed into the Peripheral Manager and read from there
78+
into the UPM library to determine the GPIO pin to be used.
79+
80+
See the top level README.md for a table describing the available GPIO pins and where to find them
81+
on the board.
