Hello just want to ask whether I can use file management in uVision3? Because I tried to use which is this " file *fp;" but i say file is an undefined identifier. What should I do to open a file to read and write can anyone tell me thanks!
The reason why I want to open a file to read and write is because I want to pass value from other program to this program. If anyone know the other method can teach me please thank alot!
Where do you fit the hard drive to your 8051? And how do you install Windows into your 8051?
You normally make use of a serial port to transfer configuration to an embedded application. And you normally make use of EEPROM or a flash sector to save that configuration.
Yes, embedded applications can do file operations. But you normally then have to add a SD memory card or similar. And then you need to add support for a file system, so the embedded application can support locating, opening and reading the files on the SD card.
