DLP9000: Controlling more than one DLP boards using a single PC

Part Number: DLP9000
Other Parts Discussed in Thread: DLPC900

Hi, I have two questions regarding controls of multiple DMD boards (i.e. Lightcrafter DLP6500 or Lightcrafter DLP9000)

(1) Can I use DLP Lightcrafter GUI to control more than one DMD separately using a single computer?

(2) I am using a MATLAB code based on Programmer's Guide Manual to control a single DMD in a pre-stored mode. If (1) is possible, can I control more than one DLP Lightcrafter using a MATLAB code?

    Hi Lihong,

    1. No GUI only supports one board on one PC.
    2. You can control multiple boards over usb by connecting to appropriate device from list of devices. Board presents HID interface.
    If matlab is listing all devices you can connect to appropriate one.

    Below is simple python script to list all devices and open one.

    import pywinusb.hid as hid
    ti_devs = get_devices(0x0451, 0xc900)
    if not ti_devs:
        print("Could not find dlpc900 device")
    print("No of devices found: " + str(len(ti_devs)))
    device = ti_devs[0]
    for dev in ti_devs:
        if dev.product_name == "DLPC900":
            device = dev
    try:
        device.open()
        print(device)
        print("Dev Opened: " + device.product_name)
    except Exception as e:
        print(e)
    finally:
        device.close()
