Tm1637 CCS C
PostPosted: Sun Aug 09, 2020 3:01 am     Reply with quote
Hello friends
I want to make a clock thermometer with TM1627, I couldn't drive.
I found a code written in c, I did not edit it
Could you help?

Code:

#include <tm1637_pic.h>

#include "DS1302.C"
#include "DHT11.C"
#include  "TM1637-BOLT.h"
#define bright MAX_BRIGHT

byte saniye,dakika,saat,gun,ay,yil,haftanin_gunu;
unsigned int  i=0;
char birler=0, onlar=0,yuzler=0,binler=0,sayi=0;
float sicaklik,nem;

long a=0;

unsigned char digits[]={0x3f, 0x06, 0x5b, 0x4f, 0x66, 0x6d, 0x7d, 0x07, 0x7f, 0x6f};

void main()
{
//port_a_pullups(0x0C);
rtc_init();
InitTM1637();

//displayValues(0,0,0,0);

output_high(pin_a3);
delay_ms(500);
output_low(pin_a3);

while(TRUE)
   {

    for(a=1;a<9999;a++)
      {
       displayValues(digits[(a/1000)%10], digits[(a/100)%10], digits[(a/10)%10], digits[a%10]);

       delay_ms(250);
      }


/*
    displayValues(0,0,0,0);
     
    displayValues(digits[(saat/10)%10], digits[saat%10] | 0x80, digits[(dakika/10)%10], digits[dakika%10]);
    delay_ms(500);   
    writeRawDigit(digits[saat%10],1);
     
 */   
   }

}



Code:

//TM1637.H
#define CLK pin_a0
#define DIO pin_a1


//#define CLK_HIGH  pin_a1
//#define DIO_HIGH TRISCbits.TRISC1 = 1

#define LOW_BRIGHT 0X00
#define MID_BRIGHT 0X02
#define MAX_BRIGHT 0X07

void InitTM1637(unsigned char BRIGHT);
void Delay_us(unsigned int useconds);
void start(void);
void ask(void);
void stop(void);
void writeByte(unsigned char oneByte);
void writeRawDigit(unsigned char segment, unsigned char nDigit);
void displayValues(unsigned char segment0, unsigned char segment1, unsigned char segment2, unsigned char segment3);

//

   Delay_us(20);
}

//

//
void start(void)
{
   output_high(clk);
   output_high(dio);
   Delay_us(2);
   output_low(dio);
}

//
//   Función que permite saber si el dato o comando enviado al display TM1637 ha sido recibido y
//   procesado correctamente
//
void ask(void)
{
   output_high(dio);
   output_low(clk);
   Delay_us(5);
   while(dio==0);
   output_high(dio);

   output_low(clk);
}

//
//   Secuencia de paro, necesaria para el correcto funcionamiento del protocolo de comunicación
//   con el display TM1637
//
void stop(void)
{
   output_low(clk);
   Delay_us(2);
   output_low(dio);
   Delay_us(2);
   output_high(clk);
   Delay_us(2);
   output_high(dio);
}

//
//   Envia por el pin DIO los bits de un byte, envia serialmente los datos
//
void writeByte(unsigned char oneByte)
{
   unsigned char i;
   
   for(i=0; i<8; i++)
     {
      output_low(clk);
      if(oneByte & 0x01)
         output_high(dio);
      else
         output_low(dio);
      Delay_us(3);
      oneByte = oneByte >> 1;
      output_high(clk);
      Delay_us(3);
     }
}

//
//   Esta función envía al módulo TM1637 un byte con la representación en 7 segmentos en la
//   posción nDigit
//
void writeRawDigit(unsigned char segment, unsigned char nDigit)
{
   start();
   writeByte(0x44);
   ask();
   stop();
   start();
   writeByte(0xC0 | (nDigit & 0x07));
   ask();
   writeByte(segment);
   ask();
   stop();
}

//
//   Envía 4 caracteres al módulo TM1637 desde la posición 0 hasta la 4 de los segmentos
//
void displayValues(unsigned char segment0, unsigned char segment1, unsigned char segment2,
               unsigned char segment3)
{
   start();
   writeByte(0x40);
   ask();
   stop();
   start();
   writeByte(0xC0);
   ask();
   writeByte(segment0);
   ask();
   writeByte(segment1);
   ask();
   writeByte(segment2);
   ask();
   writeByte(segment3);
   ask();
   stop();
}

1st line of every PIC program must be the processor type. I don't see that in your program. Something like..
#include <18f46k22.h>

2nd. can you get an LED to blink at 1Hz ? This is th efirst program you should write as it wll confirm you can compile/download code and the PIC hardware does function.

3rd. probably most important is this REAL hardware or a 'simulation' ?
Real hardware, we can help. If a 'proteus 'simulation', sorry I can't help. proteus is a very poor, defective simulator, well known to NOT be reliable or trustworthy.

First of all, thank you for your comment.

1-#include <tm1637_pic.h>
available in

2-
I wrote in the program
Code:

output_high(pin_a3);
delay_ms(500);
output_low(pin_a3);

3-
I tried both in proteus and real

You don't show us what is in tm1637_pic.h

It needs it's very first line to have:
#include <18f46k22.h>

Then the fuses and the clock definitions. The code cannot work without
these.

Code:
#include <12F683.h>
#FUSES NOWDT                    //No Watch Dog Timer
#FUSES PUT                      //Power Up Timer
#FUSES NOMCLR                   //Master Clear pin used for I/O
#FUSES NOBROWNOUT               //No brownout reset

#use delay(internal=4MHz)
#use FIXED_IO( A_outputs=PIN_A5,PIN_A4,PIN_A2,PIN_A1,PIN_A0)

I did flash to test the code is working.
Code:

output_high(pin_a3);
delay_ms(500);
output_low(pin_a3);
