Expresscard Adapter

7 Steps to Make RS232 ExpressCard Download Flash to 218X

Step One: Install CCS2.2 and check your RS232 Interface

To ensure that your source code can be compiled to Download Source: xxx.out file.

Step two: Install Serial Programming Algorithm project file: sdf28xx_v3_0_serial more information, please read the included: SDFlash_Serial_RefGuide_v3_0.pdf and Expresscard RS232.pdf files.

Step Three: In the algorithm set up the project file, the corresponding clock frequency, and generates. 1 SDFLASH 1.63 download, serial download support. 2 SDFLASH algorithm libraries

(1) In the CC file to import F2812SerialFlash.pjt

File directory: C: CCStudio_v3.1 specdig sdflash mydrivers DSP281x_v3_0 DSP281x_serial build F28xxSerialFlash

(2) set up your target board clock frequency of the corresponding

The Flash280x_API_Config.h the corresponding PLL clock, I use the 20M crystal Chun chose: define CPU_RATE 10.000L / / for a 100MHz CPU clock speed (SYSCLKOUT) (3) Save and compile the project file, generate F2812SerialFlash.out file stored in:  C: CCStudio_v3.1 specdig sdflash mydrivers DSP281x_v3_0 DSP281x_serial bin

Note: Make sure your flash program space defined in paragraph (in the CMD file changes). IF there is no RS232 Inteface,just install a RS232 Expresscard serial port adapter.

Step four: Install SdFlashV1.60 or later

Fifth Step: Edit sdopts.cfg file that is stored in your installation of windows of the System32 directory

(1) Use Notepad to open the way sdopts.cfg.

(2) "# End of sdopts.cfg" before adding the following text:

[EmulatorId = C1]

EmuPortAddr = 0xC1

EmuPortMode = RS232

EmuProductName = SERIAL_FLASH

[EmulatorId = C2]

EmuPortAddr = 0xC2

EmuPortMode = RS232

EmuProductName = SERIAL_FLASH

[EmulatorId = C3]

EmuPortAddr = 0xC3

EmuPortMode = RS232

EmuProductName = SERIAL_FLASH

[EmulatorId = C4]

EmuPortAddr = 0xC4

EmuPortMode = RS232

EmuProductName = SERIAL_FLASH

Step six: Open SDFlash, according to the methods provided by SDFlash_Serial_RefGuide_v3_0.pdf specify a file path algorithm

In the Project settings, if you chose to use the PC emulator of COM1 for the C1, COM2 select the C2

Seventh Step: The DSP-SCI_A and PC-RS232 port/Expresscard RS232 connection. Will be as follows DSP-foot tube set to the corresponding level, and then reset

Reset time: GPIOF4 = 0 GPIOF12 = 0 GPIOF3 = 1 GPIOF2 = 1

Note: GPIOf4 for SCI_A TXD terminal, reset should be restored after the completion of the original DSP is able to carry the signal state

Step seven: Click SdFlash menu Flash items --- "Click Start, you can!!!. Check your RS232 or Expresscard 34 RS232 Serial Port can work normally!

About the Author

jackdrogba is interested in computer technology..

are there any USB to ExpressCard adapters?

sort of, they do exist, but the problem is that express cards run on a pci express bus, which is ALOT faster than USB.

there are some things that will work, but many things wont work them.

your best bet is a PCMCIA to express adapter or for Desktops, a PCIe or PCI to express adapter.
