The source code for the Token I/O firmware (developed for the CCS C compiler) is available as a
free download upon purchase and receipt of the hardware. Example Visual C++ source code (for
Windows 98/2000/XP) for communicating with the DLP-245PB-G via the Token I/O firmware is
also available for download. The windows source code also contains the port pin definitions
listed above.

TOKEN I/O COMMAND SET
0xA5 – Line In – Reads the state of a single port pin
Parameters: Port – Select from available port pins (PIN_A3, PIN_B0, etc)
Returns: 1 Byte: State of the port pin (0 or 1)
Function: This function will read the state of a single port pin. If the data direction for the
pin selected was set to output, the direction is first set to input.
Example: 0x2, 0xA5, 0x2B, 0x8C - Reads the current state of port pin PIN_A3.
0xA6 – Line Out - Sets a single port pin high or low
Parameters: Port – Select from available port pins (PIN_A3, PIN_B3, etc)
State – 0 or 1
Returns: Undefined
Function: This function will change the output state of a single port pin. If the data direction
for the pin selected was set to input, the direction is first set to output.
Example: 0x3, 0xA6, 0x2B, 0x1, 0x8F – Sets port pin PIN_A3 high.
0xA7 – Return Board ID
Parameters: None
Returns: 5 bytes: “245PB”
Function: This function will return the ID of the board currently opened.
Example: 0x1, 0xA7, A6 – Reads the board ID.
0xA8 – Setup A/D
Parameters: Port Configuration – Selects analog port configuration. (See command 0xA8 in
the example firmware for options.)
A/D Conversion Clock – Select the source for the A/D conversion clock. (See
command 0xA8 in the example firmware for options.)
Returns: Undefined
Function: This function will select the source for the A/D conversion clock. (Refer to the
datasheet for the 16F877A for a detailed explanation of the conversion clock.)
Example: 0x3, 0xA8, 0x0, 0x7, 0xAC – Sets all available A/D inputs on the DLP-245PB-G
to analog mode (0x0) and selects the internal A/D clock (0x7).

0xA9 – A/D Conversion
Parameters: Analog Port Number – Selects the analog port for the A/D conversion.
Returns: 2 Bytes: The 10-bit voltage data; LSB first.
Function: This function will set the channel for the A/D conversion, pause 10uS, perform
the A/D conversion, and then return 2 bytes to the host (LSB first). Command
0xA8 must have been previously called to configure the desired analog channel
as an A/D input.
Example: 0x2, 0xA9, 0x2, 0xA9 – Selects analog channel 2 (AN2), performs the A/D
conversion, and returns 2 bytes of data.
0xAA – EEPROM Read
Parameters: Address – Selects the zero-based address of the location in the 16F877A’s
internal EEPROM for reading.
Returns: 1 Byte: The byte of data read from the EEPROM.
Function: This function will read the selected location in the 16F877A’s internal EEPROM.
Example: 0x2, 0xAA, 0x2, 0xAA – Reads EEPROM Address 2, and returns a single byte of
data.
0xAB – EEPROM Write
Parameters: Address – Selects the zero-based address of the location in the 16F877A’s
internal EEPROM for writing.
Data – Data to be written to the EEPROM.
Returns: Undefined.
Function: This function will write the selected location in the 16F877A’s internal EEPROM.
Example: 0x3, 0xAA, 0x2, 0xFE, 0x55 – Writes a value of 0xFE to EEPROM Address 2.
