SCI read and write

[oblivion 0]

Hi !

 

I have the C2000 launchpad.

I would like to send character from my PC to C2000 with the SCI (so I want to read characters with the C2000 launchpad).

 

(Example_F2802xSci_FFDLB.c and Example_F2802xSci_FFDLB_int.c don't work on my computer)

 

I want use the "Example_F2802xLaunchPadDemo.c" program and modify it in order to do that.

 

Someone does have already write something ?  

 

I assume I must re-write this part :

 

 //Redirect STDOUT to SCI

    status = add_device("scia", _SSA, SCI_open, SCI_close, SCI_read, SCI_write, SCI_lseek, SCI_unlink, SCI_rename);

    fid = fopen("scia","w");

    freopen("scia:", "w", stdout);

    setvbuf(stdout, NULL, _IONBF, 0);

 

 

TO :

 

 //Redirect STDIN to SCI

 

    fid = fopen("scia","r");

    freopen("scia:", "r", stdin);

    setvbuf(stdin, NULL, _IONBF, 0); .... and use "getchar" to read character ????

 

Can someone help me ?

 

Thank you.

 

Regards,

Oblivion

Oblivion,

 

Yes, I believe you're correct.  You would want to do something like this:

 

    status = add_device("scia", _SSA, SCI_open, SCI_close, SCI_read, SCI_write, SCI_lseek, SCI_unlink, SCI_rename);

    fid = fopen("scia","rw");

    freopen("scia:", "w", stdout);

    freopen("scia:", "r", stdin);

    setvbuf(stdout, NULL, _IONBF, 0);

    setvbuf(stdin, NULL, _IONBF, 0);

 

I haven't tested this so I can't confirm it works, but it should be close.  You can read about the CIO functions in the compiler users guide.
