3.2.2 Use of microSD Cards
The following sample program can be found in the SAMPLES\RCM3900\SD_Flash folder.
SDFLASH_INSPECT.C
—This program is a utility for inspecting the contents of a
microSD Card. When the sample program starts running, it attempts to initialize the
microSD Card on Serial Port B. The following five commands are displayed in the
Dynamic C STDIO window if a microSD Card is found:
p — print out the contents of a specified page on the microSD Card
r — print out the contents of a range of pages on the microSD Card
c — clear (set to zero) all of the bytes in a specified page
f — sets all bytes on the specified page to the given value
t — write user-specified text to a selected page
The sample program prints out a single line for a page if all bytes in the page are set to
the same value. Otherwise it prints a hex/ASCII dump of the page.
This utility works with the microSD Card at its lowest level, and writing to pages
will likely make the microSD Card unreadable by a PC. For PC compatibility, you
must use the Dynamic C FAT file system module, which allows you to work with files
on the microSD Card in a way that they will be PC-compatible.
SDFLASH_LOG.C
—This program demonstrates a simple Web server that stores a log
of hits in the microSD Card’s data flash. This log can be viewed and cleared from a
Web browser—see the NFLASH_LOG.C sample program for information on how to
access the Web page and configure your PC or workstation.
3.2.3 Serial Communication
The following sample programs can be found in the SAMPLES\RCM3900\SERIAL folder.
FLOWCONTROL.C
—This program demonstrates hardware flow control by configuring
Serial Port F for CTS/RTS with serial data coming from TxE (Serial Port E) at 115,200 bps.
One character at a time is received and is displayed in the STDIO window.
To set up the Prototyping Board, you will need to tie
TxE and RxE together on the RS-232 header at J14,
and you will also tie TxF and RxF together as shown in
the diagram.
A repeating triangular pattern should print out in the
STDIO
window. The program periodically switches RTS (TxF) flow control on or off to
demonstrate the effect of hardware flow control. You may use an oscilloscope to
observe the CTS/RTS signals to see flow control operating
