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!
Evolution of Computer
Technology can refer to material objects of use to the humanity such as, machines, hardware or utensils. It also encompasses broader themes, including systems, methods of organization, and techniques. This term can be applied either generally or specifically: like construction technology, medical technology and computer technology.
The use of technology by human race began with the conversion of natural resources into simple tools. The pre-historic discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in traveling and controlling their environment. Recent technological developments, including the printing press, the media, the telephone, and the internet have lessened physical barriers to communication and allowed humans to interact on a global scale.
Information technology and computers have attained a vital position in today’s world which is turning to a global village. The field of computers is a vast sea and there are many features and options available to choose from. Internet remains a constant and rapidly growing source of information on a broader spectrum. Now people don’t just use web browsers to gain information but can get any piece of required knowledge from any part of the world by just a few clicks on the web sites. As information is becoming much easier to access, the need of more web sites and knowledgeable sources is on the rise. New trends of web hosting, web publishing and content bloging are taking a more important place in the world of internet.
The term Information Technology was first used in November 1981, modernizing the outdated old phrase “data processing”. IT covers a broad area and is not just the domain of science related professionals but even professionals from arts and aesthetics utilize the splendors of this newly hyped source.
The early general purpose computers were made in such a way that they could easily be reprogrammed to carry out different tasks which involved plugging of switches and rerouting wirings. A number of early software designs comprised of circuits and ensured that the wires didn’t fuse. The necessity for convenience eventually allowed programmers to evolve and build basic punch-card systems. Even then, teams of technicians worked together to determine where holes were to be punched to appropriately determine change of function of the hardware of the computers.
Now software development programmers produce more complex applications by utilizing microprocessors, the cycle of more power full soft-ware and capable hardware with increasing amount of memory storage and processing powers.
Over the past decades, computing has become a model of technology usage that covers various services. These include office productivity applications to process and maintain documents and records, different web portals to view and share images videos and songs, social networking sites to interact with other net users across the globe and even net instant messaging services to communicate in real time. This list simply continues to grow.
