provided that demonstrates sending and receiving data between the host PC and USB Adapter. Four
LED’s provide visual feedback of data being received from the PC and a momentary contact, push-button
switch instructs the microcontroller to send a 512-byte data packet back to the host.
Serving as a design example, both evaluation boards have a DS-18S20 (TO-92 package) temperature
sensor connected to a port pin on the microcontroller. The DLP-EVALP and DLP-EVALS both ship with
firmware pre-programmed into their Flash (ROM) microcontroller that implements an interface to Windows
PC software that will exercise the temperature sensor, push-button, and LED’s. The Windows software
with source code (Visual C++ V6.0) and microcontroller firmware (HEX and CCS C source) is available as
a free download from www.dlpdesign.com
In the event that the user wants to reprogram the microcontroller with different firmware, a 5-pin header is
available that is compatible with the DLP-Flash programmer (purchased separately).
A single MOSFET transistor is used to drop the board's current consumption to nearly zero when the host
PC and DLP-USB245M go to Standby mode.
Refer to the schematics for these evaluation boards (available upon purchase) and the datasheets for the
Ubicom SX28 and Microchip 16F873 microcontrollers for additional details.
