65 C-Control Pro IDE

Now you can already transfer a program to the Unit. The demo programs can be found if you click in

the IDE under "Help" on "Demo Programs".

2.2.2 Firmware

The operating system of the C-Control Pro consists of the following components:

Bootloader

Interpreter

Bootloader

The boot loader is always available. It starts the interpreter or performs an upload when a new ver-

sion of the interpreter is available.

A power-on reset (turn power switch off and on) module brings the AVR32Bit always first in the

boot loader (if the Autostart-Jumper is not set). This is a safety feature to always allow access,

even if the interpreter should work incorrectly. In this state the UNIT can always be brought to its

original condition with a "Reset Module".

Pressing the reset button brings the module directly from the bootloader in the firmware when a

valid interpreter is loaded. As a result, the number of USB driver interruptions are minimized during

normal development.

Interpreter

The interpreter consists of several components:

Bytecode Interpreter

Multithreading support

Interrupt processing

User functions

RAM and EEPROM interface

In the main, the interpreter executes the byte code that was generated by the compiler. Further,

most library functions are integrated in interpreter so that the byte code program can e.g. access

hardware ports. The RAM and EEPROM interface is used by the IDE debugger to get access to vari-

ables when the debugger has stopped at a breakpoint.

2.2.2.1 Autostart

Autostart

If the Autostart Jumper is set (J1 on AVR32Bit UNIT), the user program is started directly after a re-

set or a power on. Since the Autostart-Jumper bridges the connection to the Start/Stop button per-

manently, the Start/Stop button has no effect if the jumper is set.
