Application Board
USB
The application board provides a USB interface for the program’s loading and debugging. Because of
the high data rate of this interface data transmission times are considerably shorter compared to the
serial interface. Communication takes place through a USB Controller by FTDI and an AVR Mega8
Controller. The Mega8 provides its own Reset push button (SW5). During USB operation the status
of the interface is indicated by two light emitting diodes (LD4 red, LD5 green). When only the green
LED lights up the USB interface is ready for operation. During data transmission both LED’s will light
up. This also applies to the Debug mode. Flashing of the red LED indicates an error condition. For
USB communication the SPI interface of Mega32 is used (PortB.4 through PortB.7, PortA.6,
PortA.7), which must be connected by their respective jumpers.
Note: Detailed information on the Mega32 can be found in the IC manufacturer’s PDF files on the C-
Control Pro Software CD-ROM.
On-Off Switch
The switch SW4 is located on the front of the application board and serves the power-up (On) or
power-down (Off) of the voltage supply.
