Demo Application

This application contains examples for all peripherals on the board. It is used during production test and can also be used for troubleshooting.

The Demo Application contains one class for each test/demo like this:

Graphical Demos for 4.3/5 inch LCD

The projects listed below all works with both the 4.3" and 5" displays but requires configuration in main.cpp to choose which one to use.

Audio Framework

Displays from DisplayModule

These examples all use displays from http://www.displaymodule.com/.

This example is for the 1.8" display (DM-TFT18-101) using the 40-pin connector on the Experiment Base Board. Note that this connector does not come pre-soldered.

This example will work on all of the displays shown here. Note that only the DM-TFT18-101 display can be connected to the 40-pin connector - all other displays must use the arduino compatible connector on the LPC4088 Experiment Base Board. For the displays without direct arduino pinning this requires an adapter. For more information see the overview.

This example is a basic calculator to show the use of the touch controller. It will work on all of the displays shown here which have touch support. All the touch enabled displays use the arduino compatible connector on the LPC4088 Experiment Base Board. For the displays without direct arduino pinning this requires an adapter. For more information see the overview. This shows the LPC4088 Experiment Base Board with the DM-TFT28-105 display mounted:

ePaper Display

This example is for the 2.7" ePaper display from Embedded Artists. The picture below shows the ePaper display connected to the Serial Expansion Connector.

Character LCD

This example requires a standard character LCD, of the type presented here: Text-LCD. The picture below shows the ePaper display connected to the LPC4088 Experiment Base Board.

Cellular and Positioning shield

Below is a picture with the Cellular and Positioning shield mounted. The shield is built around u-blox high-quality cellular and positioning modules.

Very simple, yet working perfect, UART pass-through application, when running u-blox m-center PC application. The cellular modem UART channel is tunneled to the mbed HDK virtual COM port (which the m-center application can connect to).

 #include "mbed.h"

Serial pc(USBTX, USBRX); // tx, rx
Serial ublox(D1, D0); // tx, rx

int main() {
    DigitalOut resetPin(D4, 1);

    // SARA-U2/LISA-U2 50..80us
    resetPin = 0; ::wait_us(50);
    resetPin = 1; ::wait_ms(10); 
    
    // SARA-G35 >5ms, LISA-C2 > 150ms, LEON-G2 >5ms
    resetPin = 0; ::wait_ms(150);
    resetPin = 1; ::wait_ms(100);
    
    pc.baud(115200);
    ublox.baud(115200);

    while(1) {
        if(pc.readable()) {
            ublox.putc(pc.getc());
        }
        if(ublox.readable()) {
            pc.putc(ublox.getc());
        }
    }
}

All the GSM/GPS examples require the following to work:

1. A working SIM card for the GSM network you want to connect to
2. The APN (Access Point Name) for the SIM. The APN is the server that allows the modem to access the internet.
3. An external power source for the GSM/GPS module. It is recommended to use a phone charger with a micro USB connector and not one of the port on the computer.

Each example must be configured with the APN information above before use. Lookup the following block in main.cpp:

//------------------------------------------------------------------------------------
// You need to configure these cellular modem / SIM parameters.
// These parameters are ignored for LISA-C200 variants and can be left NULL.
//------------------------------------------------------------------------------------
#include "MDM.h"
//! Set your secret SIM pin here (e.g. "1234"). Check your SIM manual.
#define SIMPIN      NULL
/*! The APN of your network operator SIM, sometimes it is "internet" check your 
    contract with the network operator. You can also try to look-up your settings in 
    google: https://www.google.de/search?q=APN+list */
#define APN         "online.telia.se"
//! Set the user name for your APN, or NULL if not needed
#define USERNAME    NULL
//! Set the password for your APN, or NULL if not needed
#define PASSWORD    NULL 
//------------------------------------------------------------------------------------

This example will try to fetch and post some information using HTTP requests. Only the fetching will actually work as the posting requires permissions. but the code is still good as a reference.

This is a comprehensive example that will read GPS data, use TCP sockets and respond to SMS messages. For more information look at the C027_SupportTest support page.

IoT example with Cellular and Positioning shield

The following two examples use the PubNub data stream network to publish/subscribe to data.
Note that some work is required to get this example working:

1. Create an account at PubNub.com
2. Update the program code with the publish/subscription keys received for the new account.
3. Read the PubNub documentation in order to understand the system
4. Understand that the free account has some limitations

   Import programlpc4088_ebb_ublox_Cellular_PubNubDemo
