Software Platform
In this chapter, we discuss the software architecture of the SMTK and the interfaces to it.
4.1
Software Architecture
The SMTK enables a customer to develop a Java application on a PC and have it be
executable on the TC65 module. The application is loaded onto the module. The platform
comprises:
• Basis is the Java™ 2 Micro Edition (J2ME™)
The J2ME™ is provided by SUN Microsystems, http://java.sun.com/j2me/. It is specifically
designed for embedded systems and has a small memory footprint. TC65 uses:
CLDC 1.1 HI, the connected limited device configuration hot spot implementation.
-
IMP-NG, the information module profile 2
-
identical to MIDP 2.0 but without the lcdui package.
• Additional Java virtual machine interfaces:
AT Command API
File I/O API
The data flow through these interfaces is shown in Figure 3 and Figure 20.
• Memory space for Java programs:
Flash File System:
RAM:
Applications code and data share the space in the flash file system and in RAM.
• Additional accessible periphery for Java applications
A maximum of ten shared digital I/O pins usable, for example, as:
-
Output: status LEDs
Input: Emergency Button
-
One I2C/SPI Interface.
-
One Digital Analog Converter and two Analog Digital Converters.
-
-
Serial interface (RS-232 API): This standard serial interface could be used, for
-
example, with an external GPS device or a current meter.
