2. Connect the DLP-2232MSP board to the PC via a standard A-B, 6-foot USB cable. This action
The DLP-2232MSP is shipped with default VID, PID, etc. values programmed into the EEPROM
memory. You only need to run MPROG if you want to change the default values.
At this point, the DLP-2232MSP is ready for use. Note that the DLP-2232MSP will appear
non-responsive if data sent from the host PC is not read from the FT2232H device by the
MSP430F2618 microcontroller. The token firmware with which the DLP-2232MSP comes preloaded
will read data sent by the host by default. Custom user firmware should also follow this protocol.
5.0 TOKEN I/O
The MSP430F2618 microcontroller on the DLP-2232MSP comes preprogrammed with firmware that
provides rudimentary access to the port pins via either the VCP or DLL drivers. Features include the
ability to read and write individual port pins.
The firmware in the DLP-2232MSP also provides access to the MSP430F2618’s A/D converter, D/A
converter and communications. Commands sent to the Token I/O firmware must adhere to a specific
communications protocol. Each command sequence contains the following information:
For example, setting Port Pin P1.1 high would require the following string of bytes:
0x04, 0x30, 0x11, 0x00, 0x01
Definition of the Bytes:
0x04 – Number of bytes in command
0x30 – Command for digital port pin access
0x11 – Affected port pin
0x00 – Set port pin to output
0x01 – Desired state of port pin
The port pins equate to hexadecimal numeric constants as defined here:
PORT 1:
0x10 = P1.0 MSP430F2618 Pin 12, DLP-2232MSP module Pin J1.12
0x11 = P1.1 MSP430F2618 Pin 13, DLP-2232MSP module Pin J1.13

initiates the loading of the USB drivers. When prompted, select the folder where the CDM device
drivers were stored in Step 1. Windows will then complete the installation of the device drivers for
the DLP-2232MSP board. The next time the DLP-2232MSP board is attached, the host PC will
immediately load the correct drivers without any prompting. Reboot the PC if prompted to do so.
