Duino Mega32
Intended Use
The C-Control "Duino Mega32" is an electronic component in terms of an integrated circuit.
The C-Control is designed for the programmable control of electric and electronic devices. The
structure and operation of these devices must comply with the applicable European Directives
(CE).
The C-Control must not be in galvanic connection to voltages above the safety extra-low volt-
age. The connection to systems with high voltage should only be done via VDE-approved com-
ponents. Accordingly, the prescribed clearance and creepage distances must be maintained
and the adequate measures for the protection against hazardous voltage must be taken.
On the board of the C-Control "Duino Mega32", electronic components work with high-frequen-
cy clock signals and steep pulse slopes. That may lead to the transmission of electromagnetic
interference signals when the unit is used improperly. The user has the responsibility to adopt
the appropriate measures (e.g. the use of inductors, limiting resistors, block capacitors and
shieldings) to maintain the legally prescribed maximum values.
The maximum permissible length of the connected lines without additional measures is 0,25
metres (exception serial interface). The function of the C-Control can be affected under the
influence of strong electromagnetic alternating fields or interference pulses. If necessary, a
reset and a restart of the system are required.
The power is supplied via either an external power supply unit (not provided) or via USB.
Follow the safety instructions and all other information in this operation manual.

Safety Instructions
The warranty will be void in the event of damage caused by failure to observe
these safety instructions! We do not assume any liability for any resulting
damage!
We shall not accept liability for damage to property or personal injury caused
by incorrect handling or non-compliance with the safety instructions! In such
cases, the warranty will be null and void.
• Unauthorised conversion and/or modification of the product is not allowed for
safety and approval reasons (CE).
• The product is not a toy and should be kept out of the reach of children.
• During assembly/disassembly the appropriate safety precautions against static
charge should be taken (e.g. earth connection, insulating support, etc.).
• Observe the permissible maximum current and voltage values of the individual
pins when connecting external components.
Applying a voltage that is too high or with reverse polarity or loading with a current
that is too high can instantly damage the product.
• The product must not get damp or wet.
• Handle the product with care; it can be damaged by impacts, blows or falls even
from a low height.
• Do not carelessly leave the packaging material lying around, since it could be-
come a dangerous plaything for children.

Connections and Control Elements
Programming and debugging via USB
The "C-Control Duino Mega32" board features a USB interface for the transfer and debugging
of the user programme. The PC and the Mega32 board communicate via an existing on-board
USB controller (type "Silibas CP2104") and the UART pins of the Mega32 micro-controller.
A bootloader is pre-installed on the Mega32 micro-controller, which allows you to transfer your
C-Control PRO programme from PC to the micro-controllers via USB without additional pro-
gramming device. For that purpose, a suitable USB connection cable (plug type A to plug type
B) is required (not provided).
Available programming languages: Basic, CompactC or C-GRAPH PRO.
Power supply
The "C-Control Duino Mega32" board can be powered optionally via the socket "POWER" or
via USB. The board will be automatically powered via the USB interface as long as there is no
power supply unit (output voltage 7 - 12 V/DC, min. 500 mA) plugged into the socket "POWER".
It is recommended that during experimenting, the board should not be connected
directly to the USB port of the computer. Instead it should be operated via a separate
external USB hub (with its own power supply unit). In case of error (e.g. short circuit
during experimenting), only the USB hub will be damaged and not the USB connec-
tion of your computer.
LEDs
There are four LEDs (light emitting diodes) on the board:
• LED "L": This LED is provided to the user free-of-charge and can be used as output LED. The
LED is connected with the port bit 31 / PD7 with a high impedance FET. The output will not
be blocked by the wiring of this LED. Instead it can be further connected to loads up to ±20
mA.
• LED "RX": This LED is connected to the USB chip "CP2104" and signals that the data from
the USB chip are received (that means this LED flashes when the Mega32 micro-controller
sends data to the PC).
• LED "TX": This LED is connected to the USB chip "CP2104" and signals that the data from
the USB chip are sent (that means this LED flashes when data are sent to the Mega32 micro-
controller).
• LED "ON": This LED lights up when the board is powered (USB or power supply unit).
Buttons
There are two buttons available on the "C-Control Duino Mega32":
• The button "RESET" causes the Mega32 micro-controller to reset. The programme will be
accordingly restarted.
• With the button "BOOT", the Mega32 controller is set in the bootloader mode and user pro-
gramme can be transferred from the IDE (C-Control PRO development environment) to the
Mega32. If the button "RESET" is pressed after the transfer or the "yellow flash" in the IDE or
the function button "F10" is pressed, the programme will be executed.
