Simply connect the DLP-HS-FPGA to the PC to initiate the loading of USB drivers. Once the USB
drivers are loaded, the DLP-HS-FPGA is ready for use. All commands are issued as multi-byte
command packets consisting of at least two bytes.
You can either utilize the Test Application available from
DLP-HS-FPGA (as described in Section 11), or you can write your own program in your language of
choice.
If you are using the VCP drivers, begin by opening the COM port, and send multi-byte commands as
shown in Table 1 below. There is no need to set the baud rate because the DLP-HS-FPGA uses a
parallel interface between the USB IC and the FPGA. (The Ping command can be used to locate the
correct COM port used for communicating with the DLP-HS-FPGA, or you can look in Device
Manager to see which port was assigned by Windows.) If you are using the D2XX drivers as with the
Test Application, no com port selection is necessary.
