5.3 COM Port
Communication takes place via a virtual COM port on the USB port COM . A USB-to-UART module FTDI
FT231X is used in the device for the conversion.
To communicate with an application (terminal program or application software) a hardware driver and
a driver for the virtual COM port is required. Using Windows, the drivers are normally installed
automatically. If this is not initiated automatically, you can also download the drivers from
http://www.ftdichip.com/Drivers/VCP.htm and install them manually.
In the Device Manager, entries are displayed under “USB Controller:USB Serial Converter” and under
“Ports (COM&LPT):USB Serial Port (COMxx)”.
The baud rate is set to 115 kBd. It cannot be changed.
Format: no parity bit, 8 data bits, 1 stop bit (N,8,1). End of line: <cr> or <cr><lf>.
The device can be directly controlled via the COM port using a terminal program or can be integrated
into a more complex application.
5.4 Programming
The device is controlled by an ATMEGA2560 microcontroller which operates at 16 MHz clock
frequency. The controller can be fully programmed by the user. The free Arduino IDE software is
suitable for this purpose. The entire application software of the amplifier is available for free usage.
The amplifier’s protection functions are independent of the controller and of the operation of the
application program.
