It is useful to put the chip into this mode to save energy when the device is waiting for an event to happen (the chip’s timers are stopped in this mode, so the wake up events must be related to I/O).

Note: The code for the tutorial includes commented out lines for switching the chip in and out of embedded ultra low power mode.

The LED will blink (Timed Blink application) and when the white push button on the Development Board is pressed, the messages “Hello World” and “Hello again!” will be sent over the serial port.
Once loaded, switch to Embedded Mode – the application (and Timed Blink if still loaded) will start to run as soon as the power is switched back on.
Erase an application using its AID e.g.: hterm -serial COMx -cardtype MI-M5 -deleteaid F4000001. Erase all applications: hterm -serial COMx -cardtype MI-M5 -clean. If you need to delete an existing application there are two basic options:. This time the script does not delete existing applications from the device. You will need a tool to read the serial port such as CoolTerm.Īs before, to load the application, ensure that the Development Board is in Command Mode and run the loader.bat script. This application introduces using the default serial port in an application and the handling of GPIO events. This application can be loaded alongside the Timed Blink application, demonstrating how more than one application can be registered to respond to events in Embedded Mode. Care must be taken, however, as this setting applies to the whole chip and all embedded applications running on it. It is useful to put the chip into low power mode to save energy when the device is waiting for an event to happen (including timer events). Note: The code for the tutorial includes commented out lines for switching the chip in and out of embedded low power mode. Once loaded, switch to Embedded Mode – the application will start to run as soon as the power is switched back on. To load the application, ensure that the Development Board is in Command Mode and run the loader.bat script. In this example, a timer event is used to blink an LED. On receipt of an event, MULTOS calls the applications that have registered an interest in that event (they are called in the order they were loaded to the device). Each application loaded to the device registers the events it is interested in and provides the code required to handle those events. This introduces the concept of running a MULTOS Trust Anchor in Embedded Mode. This example can be run through the debugger in Eclipse or by using the batch file build_run.bat as shown below. The structure of an APDU is described in the MULTOS Developers Guide in section 3. The number of times to flash is given in the command P1 parameter and the gap between flashes (in seconds) by the P2 parameter. 
This application will flash the on-board LED. Jump to the following tutorials: LED Flash | Timed Blink | Hello World | I2C Master | I2C Slave | SPI Master | Sending APDUs in Command Mode | Two Serial Ports | Abend / Fault Handling | Wifi | Application Updating Turn the MULTOS chip back on (switch S1 in the up position).Fit (command mode) or remove (embedded mode) the jumper JP5.Turn off the MULTOS chip (switch S2 in the down position).Note: you will need to edit the COM port number in all the batch files to match that on your computer.Īt various stages you maybe prompted to switch the Development Board between Command Mode and Embedded Mode. The source code is fully commented and provides the main guidance for these tutorials. It also contains the necessary Arduino sketches for each project. The MULTOS workspace can be downloaded from here. The following tutorials use the Development Board.
