jensdehoog 0:fd29cd85e75e 17 - Check if the button has been pressed. If so, print the amount of clicks to a serial terminal.
jensdehoog 0:fd29cd85e75e 18 - Make an MQTT-service which:
jensdehoog 0:fd29cd85e75e 19 - starts up a network using EthernetInterface. Make sure the development board requests its address via DHCP.
jensdehoog 0:fd29cd85e75e 20 - makes a client and connects it to the broker using a client ID and credentials (username & password).
jensdehoog 0:fd29cd85e75e 21 - sends messages at the same topic as the smartphone app from PGO 2. Feel free to choose which Quality of Service
jensdehoog 0:fd29cd85e75e 22 you are going to use. Make a separate function which handles the sending procedure. Therefore, this function
jensdehoog 0:fd29cd85e75e 23 can be called each time we want to send a certain message.
jensdehoog 0:fd29cd85e75e 24 - When the button is pressed once, we send an upvote. When pressed twice, a downvote is sent. By pressing 4 times,
jensdehoog 0:fd29cd85e75e 25 the program disconnects from the broker and terminates.

jensdehoog 0:fd29cd85e75e 29 - Subscribe to the topic on which the song data is published. Display this received message on the serial terminal.
jensdehoog 0:fd29cd85e75e 30 - Test this controller in the complete system of PGO 2. Use these controllers instead of the smartphones.

jensdehoog 0:fd29cd85e75e 32 Tips & tricks
jensdehoog 0:fd29cd85e75e 33 -------------
jensdehoog 0:fd29cd85e75e 34 - To generate an interrupt on the press of a button, use:
jensdehoog 0:fd29cd85e75e 35 InterruptIn button(USER_BUTTON);
jensdehoog 0:fd29cd85e75e 36 ...
jensdehoog 0:fd29cd85e75e 37 button.fall(callback(someFunction));
jensdehoog 0:fd29cd85e75e 38 - Before implementing MQTT, test the multiclick feature first.
jensdehoog 0:fd29cd85e75e 39 - Have a look at the MQTT-library for Mbed and the HelloMQTT-example.
jensdehoog 0:fd29cd85e75e 40 - To have a uniform message sending procedure, use the following function usage:
jensdehoog 0:fd29cd85e75e 41 sendMessage(&client, topic, buf, qos, retained, duplicate)
