Embedded Applications

The Wireless CPU has the capability to store and run customer written code in the
form of a script during the processor's idle time, through the use of an on board
interpreter.
8.1

Features

Main features of embedded applications are as follows:
•
•
•
•
8.2

Implementation

The Wireless CPU has 2x124KB of non volatile memory space available for storage of
two scripts in the scripting language. The maximum size of a single script is 124K,
regardless of the size/presence of the other script. 224KB of RAM is set aside for the
script usage.
portion, the RAM available for the script to use for variables is 224KB – size of the
script.
Structures included in this language are:
•
•
•
All hardware interfaces that are normally available to the Wireless CPU through the AT
commands, are also available to the embedded application.
Further drivers have been written such as M bus, keypad, SPI and I2C for use by the
embedded application (EA) through the use of the I/O pins.
