... USB / Microcontroller Module (Lead-Free) The DLP-245PL-G combines the same lead-free USB interface used in the DLP-USB245M-G module with a Microchip PIC microcontroller to form a rapid development tool. The 18LF8722 microcontroller is preprogrammed with basic functionality for accessing the port pins and can be reprogrammed with user hex code via a 5-pin header that is compatible with Microchip’ ...

... USB bar code readers GENERAL DESCRIPTION The DLP-245PL-G provides a cost-effective, microcontroller-based method of interfacing an electronic peripheral to a host computer via USB. To send data from the peripheral to the host computer, the microcontroller simply writes the byte-wide data into the FT245RL when TXE# is low. If the FT245RL’s transmit buffer fills busy storing the previously written byte, it will take its TXE# high in order to stop further data from being written until some of the FIFO data has been transferred over USB to the host ...

... COM (RS-232) port. In addition to VCP drivers, FTDI's D2XX direct drivers for Windows offer an alternative solution to the VCP drivers that allow application software to interface with the DLP-245PL-G using a DLL instead of a Virtual Com Port. The architecture of the D2XX drivers consists of a Windows WDM driver that communicates with the FT245RL device via the Windows USB stack and a DLL that interfaces the application software (written in VC++, C++ Builder, Delphi, VB, etc ...

... Jumper JP1 allows for this configuration. Select JP1 Pins 1 and 2 if the DLP-245PL take its power from the USB port on the host computer; jumper JP1 Pins 2 and 3 if the DLP-245PL take its power from your external power source. ...

... Features include the ability to read and write individual port pins as well as 8-bit port reads and writes. The firmware in the DLP-245PL-G also provides access to the 18LF8722’s A/D converter, EEPROM memory, and communications with digital temperature-sensing devices. Commands sent to the Token I/O firmware must adhere to a specific communications protocol. ...

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