 Posted: Tue Jan 25, 2011 11:28 am Post subject: Pls help--unable to display/catch call_control info |
 |
|
Hello,
I am trying to get call_control info on display below, but I am receiving garbage. Please help.
| Code: |
void disply (void * x)
{
display_text_raw (x, Q_DISPLAY_TEXT_HIGH_PRIORITY |
Q_DISPLAY_TEXT_DELAY_CLEAR);
}
void call_control (u8 * s)
{
u8 *get_resp_call;
u8 get_resp_call_len = 0;
u8 *tmp = malloc (100);
get_resp_call[get_resp_call_len++] = CALL_STAT_MODIFY;
get_resp_call[get_resp_call_len++] = 0x00; //len
get_resp_call[get_resp_call_len++] = T_ADDRESS;
get_resp_call[get_resp_call_len++] = 0x00; //len
get_resp_call[get_resp_call_len++] = 0x81;
.........
..........
memcpy(tmp, get_resp_call, (get_resp_call_len - 2));
tmp[get_resp_call_len-1]='\0';
stk_thread(disply, tmp);
}
|
It would be really helpful if someone can kindly point out where I am doing wrong in capturing the array info. Many thanks. |

You are trying to print non-ascii/printable chars, so you get garbage.
Use some converstion to hex, sprintch()...
Don't forget to free(tmp) |

Thanks a lot,pz. Sorry for the late reply. Didn't realize u replied. I will use sprintch to convert to hex before displaying. |

Hi pz,
I would really appreciate a bit further help on this. This is how I am trying to access T_ADDRESS of call_control but still getting garbage.
| Code: |
u8 j2,l2,i2;
u8 *r2 = buf_B ();
u8 *buf = malloc (200);
memcpy(buf, &get_resp_call[2] , get_resp_call_len );
j2 = get_tag (buf, T_ADDRESS);
if (j2 != 0)
{
l2 = buf[j2 + 1];
for (i2 = 0; i2 < l2; i2++)
r2 = sprintch (r2, buf[j2 + 2 + i2]);
r2 = sprintc (r2, '\0');
}
stk_thread(bum, buf_B()); //calling display_text_raw
free(buf);
|
Please can you help me on what I am doing wrong? Many thanks. |

Try memcpy(buf, &get_resp_call[1] , get_resp_call[1]+1);
get_tag() should point to buffer starting with len, you are skipping it. |
