7.0 EEPROM SETUP / MPROG
The DLP-2232H-PSOC5 has a dual-channel USB interface to the host PC. Channel A of the high-
speed USB interface is connected to the PSoC ? 5 in FIFO parallel mode to allow for the fastest
possible transfers between the USB host and the PSoC ? 5. Channel B of the high-speed USB
interface is connected to the PSoC ? 5 in serial mode to allow for UART communication between the
host PC and the PSoC ? 5. A 93LC46B EEPROM connected to the USB interface IC is used to store
the setup for the two channels. The parameters stored in the EEPROM include the Vendor ID (VID),
Product ID (PID), Serial Number, Description String, driver selection (VCP or D2XX) and port type
(UART serial or FIFO parallel).
To support the configuration described above, Channel A of the USB device must be configured in
245 FIFO mode, and Channel B of the USB device must be configured in RS232 UART mode. Either
VCP or D2XX drivers can be used. By default, the USB device EEPROM configuration is set for
D2XX drivers on both channels with 245 FIFO on Channel A and RS232 UART on Channel B. The
D2XX drivers provide faster throughput but require working with a *.lib or *.dll library in the host
application. The VCP drivers make the DLP-2232H-PSOC5 appear as two RS232 ports to the host
application.
The operational modes and other EEPROM selections are written to the EEPROM using the MPROG
utility. This utility and its manual are available for download from the bottom of the page at
www.dlpdesign.com .
8.0 TEST HEX FILE
A test hex file derived from the reference design described earlier is provided as a download from the
DLP Design website to customers who purchase the module. This design provides rudimentary
access to the I/O features of the DLP-2232H-PSOC5. The DLP-2232H-PSOC5 module comes
preprogrammed with this file. The following features are provided:
?
?
?
Ping
Read the High/Low State of the I/O Pins
Drive the I/O Pins High/Low or Read their High/Low State
This hex file is available from the DLP-2232H-PSOC5’s download page. (The command structure
that supports these features is explained in Section 10.)
