Hello.
I am trying to read and write integers from a text file in Code compose using fopen and fprintf, however I am unable to open the file that I am reading from(give me a "Could not open data.txt". I am trying to write an application for students in my class, so I would like to figure this out quickly.
FILE *filepointer;
FILE *file;
int character;
filepointer=fopen("coeff", "r+"); /* filepointer points to data.txt */
file=fopen("coeff", "r+");
//file = fopen("file.txt","r+"); /* apend file (add text to
//a file or create a file if it does not exist.*/
if (filepointer==NULL) { /* error opening file returns NULL */
printf("Could not open data.txt!\n"); /* error message */
//return 1; /* exit with failure */
}
while ((character=fgetc(filepointer)) != EOF) {
putchar(character); /* print the character */
//fprintf(file,"%c",character); /*writes*/
//printf ("%d ", i);
//fscanf (filepointer, "%d", &i);
}
/* Initialize BSL */
read_ints ("");
USBSTK5505_init( );
/* Initialize the Phase Locked Loop in EEPROM */
pll_frequency_setup(100);
/* Initialise hardware interface and I2C for code */
aic3204_hardware_init();
/* Initialise the AIC3204 codec */
aic3204_init();
printf("\n\nRunning FIR Filters Project\n");
printf( "<-> Audio Loopback from Stereo Line IN --> to HP/Lineout\n\n" );
/* Set sampling frequency in Hz and ADC gain in dB */
set_sampling_frequency_and_gain(SAMPLES_PER_SECOND, GAIN_IN_dB);
