DigiLite

The FT2232H USB module has two input/output ports, either of which can be configured to be one of several device types.The factory configuration is two uarts (serial ports). For DigiLite, the first port needs to be configured as a FIFO (first in first out byte memory).
Preparation
Do not insert the dsPIC chip until the FT2232H module has been configured.Download and unzip the FT2232H VCP (not D2XX) drivers from here:http://www.ftdichip.com/Drivers/VCP.htm . Note where you have saved them.Download and unzip the FT2232H Configuration program (FT_PROG) from here:http://www.ftdichip.com/Support/Utilities/FT_Prog_v2.4.zip
With the FT2232H installed in a serialiser, connect it to a USB port on the PC.Give the location of the drivers when asked. You will need to do this several times until all the components of the FT2232H drivers have been installed.
Editing the Configuration
With the FT2232H connected, run FT_PROG (FT_PROG needs Microsoft .Net Framework 3.5
You will be prompted to allow this to be installed if it is not already on your PC. It may be several 10s of MB). Make sure that the EEPROM tab at the top of the window is selected.Click DEVICES and then SCAN AND PARSE. The FT2232H should be detected. If there are other USB devices from the same manufacturer connected, click on the DEVICE line for each device in the left hand box until the FT2232H is found.
(If you get an error message here it may mean that the two sets of drivers are not in ok.See here** and Reinstall)
In the left hand box, click USB Config Descriptor
In the right hand box, set Max Bus Power to 250mA.In the left hand box, click USB String Descriptors
In the right hand box, tick Serial Number Enabled.

In the right hand box, untick Auto Generate Serial No.
In the right hand box, set Serial Number to DATV
In the left hand box, click on the + sign next to Hardware Specific
In the left hand box, click on the + sign next to Port A
In the left hand box, click on Hardware on the next line down.
In the right hand box, select 245 FIFO.
In the left hand box, click on Driver on the next line down.
In the right hand box, click on Virtual Com Port (if not already selected).
In the left hand box, click on the + sign next to Port B
In the left hand box, click on Hardware on the next line down.
In the right hand box, select RS232 UART (if not already selected).
In the left hand box, click on Driver.
In the right hand box, click on Virtual Com Port (if not already set)

Programming the Configuration
Near the top of the Window, click DEVICES and then click PROGRAM. A new window appears. If more than one device is shown, make sure that only the FT2232H device is ticked. Look at the previous (main) window for the device number.Click PROGRAM It should only take a few seconds and then Finished Programming should appear in the bottom left of this window.Close the programming window, close FT_PROG, disconnect the FT2232H and reconnect.Go back up to Editing the Configuration and check that Port A Hardware is set to 245 FIFO.Close FT_PROG.
Finding which COM ports have been assigned**
Look in Windows Control Panel / System / Hardware / Device Manager / Ports.They should appear as USB Serial Port.If you are not sure which are the FT2232H ports, unplug the FT2232H and reconnect to see which ports disappear and reappear.After configuration, these port numbers will remain the same whichever USB port the FT2232H is connected to. In DigiLite Config, enter the lower port number as the DATA port and the higher as the CONTROL port.
If this seems all too much for you, just purchase a ready programmed USB module from the BATC Shop!
