I am writing code for the omap3530 DSP and would like to read a txt file. When I use fopen to open the file it returns a File * to the opened file but based on the memory content of the File * there is nothing in the file.
#include <stdio.h>
void uint_read_file(const char* const filename, _iq19* const data, const uint16_t dataSize) {
if (filename != 0 && data!= 0) {
FILE* const file = fopen(filename, "r");
if (file != 0) {
uint16_t index;
for (index= 0; index< dataSize; ++index) {
float value = 0;
const int SCAN_COUNT = fscanf(file, "%f", &value);
if (SCAN_COUNT == 1) {
filename[index] = _FtoIQ19(value);
}
}
/* close the file */
fclose(file);
}
}
}
After the fopen statement I see the following contents in the File * in the watch window:
file 0x1080CE48 FILE * hex NotEdited
fd 0x00000003 int hex NotEdited
buf 0x00000000 "\021" unsigned char * hex NotEdited
pos 0x00000000 "\021" unsigned char * hex NotEdited
bufend 0x00000000 "\021" unsigned char * hex NotEdited
buff_stop 0x00000000 "\021" unsigned char * hex NotEdited
flags 0x00000011 unsigned int hex NotEdited
Couple of observation:
1) "pos" should not be equal to "bufend" right following the executing of the fopen statement
2) the fscanf statement in the code returns a value of -1 when it tries to scan the File *
3) I have confirmed that there is data in the file
Does CCS support fopen?
Why does it not read the text file in properly?
thanks
