File I\O - changing the directory of a file

Prakash Kumar Thulasi Kumar
Expert 2015 points
Other Parts Discussed in Thread: CONTROLSUITE

Hi Guys,

I am using TMS32F28027 MCU and I have written a program for 3 phase Voltage measurement. I want to check my program by writing all the calculated values in an excel file using fwrite fuction. As the RAM has limited memory the compiler gives the following errors.

Is there any way to create excel file in another directory other than the RAM (for eg. in hard disk )?

Normally in eclipse IDE the line myFile = fopen("file.csv", "w"); is replaced with myFile = fopen("D:\\file.csv", "w"); to change the directory. This doesn't work in CCS.

Also I am open to other suggestions for checking the calculated voltage values. Thank You.

    Prakash, instead burst out the data through SCI into terminal app and later link it to excel externally. file operations are that too for F28027 would not be reliable.

    Check this: processors.wiki.ti.com/index.php/Tips_for_using_printf

    Hi Gautam,

    Thanks for your reply. I didn't want to make things complicated for me with SCI. So I decided to use printf function. I set the heap size to 0x400. Reallocated the memory for IQTables to RAMM0, but still get errors.

    CODE:
    #include <stdio.h>
    int main(void) {
    printf("Hello, world!");
    return 0; }

    MEMORY
    {
    PAGE 0 :
    /* For this example, L0 is split between PAGE 0 and PAGE 1 */
    /* BEGIN is used for the "boot to SARAM" bootloader mode */

    BEGIN : origin = 0x000000, length = 0x000002
    RAMM0 : origin = 0x3FE000, length = 0x000C86
    PRAML0 : origin = 0x008000, length = 0x000900
    RESET : origin = 0x3FFFC0, length = 0x000002

    // IQTABLES : origin = 0x3FE000, length = 0x000B50 /* IQ Math Tables in Boot ROM */
    // IQTABLES2 : origin = 0x3FEB50, length = 0x00008C /* IQ Math Tables in Boot ROM */
    // IQTABLES3 : origin = 0x3FEBDC, length = 0x0000AA /* IQ Math Tables in Boot ROM */

    BOOTROM : origin = 0x3FF27C, length = 0x000D44

    PAGE 1 :

    /* For this example, L0 is split between PAGE 0 and PAGE 1 */
    BOOT_RSVD : origin = 0x000002, length = 0x00004E /* Part of M0, BOOT rom will use this for stack */
    RAMM1 : origin = 0x000050, length = 0x0007B0 /* on-chip RAM block M1 */
    DRAML0 : origin = 0x008900, length = 0x000700
    }

    SECTIONS
    {
    /* Setup for "boot to SARAM" mode:
    The codestart section (found in DSP28_CodeStartBranch.asm)
    re-directs execution to the start of user code. */

    .text > RAMM0, PAGE = 0

    // IQmath : > PRAML0, PAGE = 0
    // IQmathTables : > IQTABLES, PAGE = 0, TYPE = NOLOAD
    }

    Did you follow the wiki link thoroughly? There seems to be an error in linking. Check your .text:rts section

    Expert 2015 points
    Thanks again Gautam.
    It seems the size of .text:rts is 0x1b2a. Now I allocated more memory to RAMM0.
    It compiles and when I debug and run it, nothing gets printed in the CDT Build Console[print].
    Am I missing any settings here? Please let me know.

    At last I am using breakpoints to write data to txt file. The following video shows how it is done.
