1.3.1.16 Firmware Operation

Problem

What are the different parts of the software (monitor, firmware, user configuration data) ?

Solution

The structure of the software is shown below :

The Monitor Firmware provides the minimum set of functions necessary to connect a PC to the

Touchscreen and re-program the Application Firmware or Configuration Data. The Monitor

Firmware is not field upgradeable. This guarantees that it is always possible to reprogram the unit

following a failed Firmware upgrade. Note that the monitor firmware does not exist in C-Touch

Mark 2.

The Application Firmware provides all of the Touchscreen functionality. It uses the User

Configuration Data to generate the displays and to respond to C-Bus and user input as required.

The Application Firmware is field upgradeable, although it should only need to be done if new

features or bug fixes are required.

The User Configuration Data controls what is displayed, and how the Touchscreen responds to

user and C-Bus input. The User Configuration Data is downloaded as required.

Problem

What is happening during the start-up of C-Touch ?
