Using ADSP-CM403F EZ-KIT Lite
The display is written using the TWI interface. The TWI address of the
display is
0x50
. The maximum clock rate for the display is 100 kHz. The
display can be removed if the frequency limitation poses a problem.
For more information, refer to the serial liquid crystal display example in
the POST, which is included in the ADSP-CM40x Enablement Software.
Power-On-Self Test
The Power-On-Self-Test Program (POST) tests all EZ-KIT Lite peripher-
als and validates functionality as well as connectivity to the processor.
Once assembled, each EZ-KIT Lite is fully tested for an extended period
of time with POST. All EZ-KIT Lite boards are shipped with POST pre-
loaded into flash memory. The POST is executed by resetting the board
and pressing the proper push button(s). The POST also can be used as a
reference for a custom software design or hardware troubleshooting.
Note that the source code for the POST program is included in the
ADSP-CM40x Enablement Software along with the
readme.txt
file that
describes how the board is configured to run POST.
Expansion Interface
The expansion interface allows a custom-design daughter board to be
tested across various hardware platforms that have the same expansion
interface.
The expansion interface implemented on the ADSP-CM403F EZ-KIT
Lite consists of three connectors:
Asynch or Memory Connector (J2)
,
, and
. The connectors con-
tain a majority of the processor’s signals. For pinout information, go to
