2. Connect the DLP-2232MSP board to the PC via a standard A-B, 6-foot USB cable. This action

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.

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:

Byte 0: Number of bytes in command sequence

Byte 1: Command

Byte 2…n: Parameter/data bytes

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

The source code for the Token I/O firmware (developed using the CCS C compiler) is available as a

free download upon purchase and receipt of the hardware. Example Visual C++ source code

developed using Microsoft Visual C for communicating with the DLP-2232MSP via the Token I/O

firmware is also available for download. (The Windows source code also contains the port pin

definitions listed above.)

: Setting the ADC mode to continuous (1) starts an infinite loop. The ADC

will perform a conversion approximately once a second and report the result to

the host. To exit, break the code using the debugger or reset the module.

Returns: 2 Bytes: The 12-bit voltage data; MSB first

Function: This function will enable A/D conversion on the selected channel and ADC, pause

10uS, perform the A/D conversion and then return 2 bytes to the host (MSB first).

Command 0x42 must have been previously called to configure the desired analog
