[SIZE=4][B][COLOR=Blue]Hi...!!!
I want to take/read file(.txt format doc format) continuously as an input for one of my application on I2C.
But when I use FILE *file and file =fopen("filename.txt","r"); it is showing error and I tried few more things but it is showing error.
I have used #include "debug_printf.h" , #include "stdlib.h" and other required driver files, but still error is coming.

Please guide me on this or share any document available on c functions for LPCxpresso.

Thanks....:)[/COLOR][/B][/SIZE]

Why don't you learn to program in C elsewhere. Hint - why don't you include stdio.h which actually includes the IO functions

BTW:
DO NOT SPAM THIS FORUM. YOU WILL BE BANNED.

#1 Learn something about C programming ;)

#2 Switch on your brain :rolleyes:

#3 Listen to your compiler:

Your compiler is telling you very polite what is wrong :)

Let met translate it for you:

"Hello idiot user, I don't know this 'File'. What is it? A dead cat? Are you drunken or just too dump to write :confused:"

..and to give you another hint (my last one) use FILE (which is defined in stdio.h) and not File (which is nothing to do with standard C).

What are you trying to do ? Explain your project.
Where do you want to send the memory content ? To the LPC memory? to the PC ?
Will your application run in stand alone ?

Your architecture is not really clear.

How is connected the camera? which interface? I2C ?
Do you have already this interface working in a test project ?

Is there any protocol to read/write data from/to the camera ?
Do you have already this protocol working in a test project ?

How is connected your board to the satelite (host) computer ? RS232 ? Ethernet ? USB ?
Do you have already this interface working in a test project ?

Is there any protocol to read/write data from/to the host PC ?
Do you have already this protocol working in a test project ?

Is your developement harware setup equal to the final application hardware?

I am trying to implement I2C protocol for my satellite project, but right now we are trying to read any file(.txt or other format) in LPCxpresso using LPCxpresso Rev. Board and LPC1114/301 emulator.
Kindly help me on this.
I tried to read a file using FILE*fpp1, but it is not happening.

Thanks & Regards :)
