Decodeder to Remote with Manchester..
I have problems with my code..
decode a remote with HT6P20D...
My code to recive the codifier of remote control...
but have problems... i don t know why...
| Code: |
#include <16F628A.h>
#fuses NOWDT,INTRC_IO, NOPUT, NOPROTECT, NOBROWNOUT, NOMCLR, NOLVP, NOCPD
#use delay(clock=4000000)
//********************
#define CS_LCD PIN_B3
#define RS_LCD PIN_B2
#define D4_LCD PIN_B4
#define D5_LCD PIN_B5
#define D6_LCD PIN_B6
#define D7_LCD PIN_B7
#include <LCD_16x2LIB>
//********************
unsigned int time1,time2,i,tot,z,t2,t1;
byte cod1,cod2,cod3;
int32 codif;
float float_seconds;
byte edge_flag;
#INT_EXT // inicio do interrupt ****************
void ext_isr()
{
if (edge_flag==1)
{ //do l_to_h things
time2=get_timer0(); //pega o tempo do nivel baixo , ou seja em 0 (time 2)
set_timer0(0);
i++;
tot=time1+time2;
if (( tot <20 ) || ( tot >65 ))
{
//zera variaveis!!
codif=0;
i=0;
edge_flag = 3; //set flag, so l_to_h code is executed in interrupt
ext_int_edge(l_to_h);
}
else
{
edge_flag = 0;
ext_int_edge(h_to_l);
if (time1<time2) //se verdadeiro , bit=1
{
codif = codif << 1;
codif = codif + 1;
}
else
{
codif = codif << 1;
}
if (i==24)
{
printf(exibe_lcd,"\f codif%lu",codif);
//zera variaveis!!
codif=0;
i=0;
edge_flag = 3; //set flag, so l_to_h code is executed in interrupt
ext_int_edge(l_to_h);
}
}
}
else
if (edge_flag==0) //TERCEIRO INTERRUPT
{ //...do h_to_l things
time1=get_timer0(); //pega o tempo do nivel alto , ou seja em 1 (time 1)
set_timer0(0);
edge_flag = 1;
ext_int_edge(l_to_h);
}
else //if (edge_flag==3) //PRIMEIRO INTERRUPT
{
set_timer0(0);
edge_flag = 0;
ext_int_edge(h_to_l);
}
}
void main()
{

edge_flag = 3;
ini_lcd_16x2();
setup_timer_0(RTCC_INTERNAL | RTCC_DIV_32);
output_low(PIN_a0);
printf(exibe_lcd,"\f START.."); //exibe o texto na tela!
delay_ms( 1000 );
edge_flag = 3; //set flag, so l_to_h code is executed in interrupt
enable_interrupts(global);
enable_interrupts(INT_EXT);
ext_int_edge(l_to_h);
set_timer0(0);
while (TRUE)
{
}
}

Your code was not posted correctly. Notice the line shown in bold below.
| Quote: | tot=time1+time2;
if (( tot <30>55 ))
{ |
This happened because HTML is enabled for your post.
You need to edit your post. Delete all the code in your original post.
Then post in the correct code from your program. But this time,
when you post it, make sure that you select the "Disable HTML" box.
It's just below the posting window. It looks like this:
| Quote: | | x Disable HTML in this post |
Also, give a more detailed explanation of what you expect your code
to do, and then explain in detail what it's currently doing, and why it
is not correct. |

i edit my first post....
The problem is:
The time T of my remote controle is = 45
But I need to put :
if (( tot <20>65 ))
//more then 10% of erro
if I put
if (( tot <35>55 ))
//don t works... doing this, don t recieve a valid bit
i think have a big delay in my code...
but i don t know where and why...
****
i'm a brazilian...
sorry for my mistakes in the english

Study the CCS driver for decoding a TV remote control.
Here is the file location:
c:\program files\picc\drivers\n9085ud.c
| Quote: |
// Library for the N9085UD VCR / TV remote
// Note: This driver uses timer one to decode a signal. |

Thank for your help
I study this lib....
i need to modify some things in this lib.
i don t undestand , the part in the lib of width_buffer ....
what i need to put in width_buffer ? and in TIMER_RATE?

I think width_buffer is just an internal buffer used by the driver.
I don't know anything the N9085UD.C driver. CCS doesn't provide an
example program that shows how to use the driver. I did a search with
Google for some of the functions in the driver, and found this page in
the Google cache.
http://209.85.129.104/search?q=cache:_gsPjmdKRNoJ:www.datadynamics.co.jp/ccs/robotics_tutorial.pdf
Look about 2/3 of the way down that page, at Sections 14 and 15.
There is sample code that calls the driver. |

I can't offer any more help, because I haven't done a remote control
project and I don't have any more time to spend on it. |
