USB Interface
The USB Serial interface on the Polmaddie6 is achieved using an FT232R USB to serial UART
interface. The datasheet and drivers for this device are available from
http://www.ftdichip.com
.
When appropriate drivers are installed the Polmaddie6 USB port should be detected as a serial port.
Alternative data optimised drivers are also available from FTDI. The FT232R is connected to the
FPGA and provides a simple UART interface i9ncluding hardware flow control. This allows a host
computer to communicate to the MAX 10 FPGA using a simple serial protocol.
The connections between the USB Serial device and the FPGA are shown below:
