Help with my code

[diluc_3555836]

Hello

I want to ask if there is a way to make a code work interchangeably with another code, I am programming a set of relays, but when these work they prevent me from executing an lm35 sensor and when the relay has already made its cycle, the lm35 starts running.

The cycle is repeated again, the relays work and the reading of lm35 is cut, then, once the relay cycle is completed, the sensor re-read the temperature again.

How can I make the lm35 read to me without being cut when the relays work? that work together without one cut me reading another. It's just code, probe putting functions and the result was the same, the program runs and the sensor does not go at the same time as the relays, they work first and then the lm35

Someone had this experience, how could he solve it.

I attach my program.

There are some ways out to have two different tasks running at the "same" time.

Using an RTOS (when taking the time to learn how to handle it) is a common solution.

Having a timer that wakes up and signals to handle a (short) task at periodic times

Designing one of the tasks to be interrupt driven thus running in the background

For the sake of compatibility; Can you please post your complete project so that we all can have a look at all of your settings. To do so, use

Creator->File->Create Workspace Bundle (minimal)

and attach the resulting file.

Hi,

How about changing main.c like below?

=============================

#include "project.h"

#include "stdio.h"

int32 entero,voltaje;

float32 temp;

char str[16];

/**

* relay

* decide what to do depending on the accumulated time

*/

void relay(uint32_t time)

{

    switch(time) {

    case 0: // at 0sec

        Test_Tube_Write(0);

        break ;

    case 3000: // at 3sec

        Sample_Write(0);

        break ;

    case 8000: // at 8sec

        Molish_Write(0);      

        break ;

    case 10000: // at 10sec

        Sample_Write(1);

        Test_Tube_Write(1);

        break ;

    case 19000: // at 19sec

        Molish_Write(0);

        break ;

    }

}

/**

* measure

* currently measure each sec

* the interval can be decided by changing 1000 of "if (time % 1000) {"

*/

void measure(uint32_t time)

{

    if (time % 1000) { // measure only each 1sec => ((time % 1000) == 0)

        return ;

    }

    /*SENSOR LM35*/

    ADC_StartConvert();

    ADC_IsEndConversion(ADC_WAIT_FOR_RESULT);

    entero = ADC_GetResult32();

    ADC_StopConvert();

    voltaje = ADC_CountsTo_mVolts(entero);

    temp = ((voltaje/10.00)-07.00);

    sprintf(str,"%.1f",temp);

    LCD_I2C_setCursor(6,1);

    LCD_I2C_print(str);   

}

int main(void)

{

    uint32_t time = 0 ;

    uint32_t delta = 1 ; /* time resolution 1ms */

    CyGlobalIntEnable;

    I2C_Start();

    LCD_I2C_start();

    Opamp_Start();

    ADC_Start(); 

    LCD_I2C_setCursor(0,1);

    LCD_I2C_print("Temp:");

    for(;;)

    {

        relay(time);   

        measure(time) ; /* measure every 1sec */

        time = (time + delta) % 31000 ; /* 0 ~ 30999 = 31 sec cycle */

        CyDelay(delta) ;

    }

}

Hi,

My new CY8CKIT-059 has just arrived from Digi-Key, as my old one is occupied with another project,

I could not tested, but now I can 😉

So to use UART, I modified the main.c like below

===============================

#include "project.h"

#include "stdio.h"

#define USE_UART 1

#if USE_UART

void print(char *str)

{

    UART_PutString(str) ;

}

#endif

int32 entero,voltaje;

float32 temp;

char str[16];

void relay(uint32_t time)

{

    switch(time) {

    case 0: // at 0sec

        Test_Tube_Write(0);

        print("\tTest_Tube_Write(0)\n") ;

        break ;

    case 3000: // at 3sec

        Sample_Write(0);

        print("\tSample_Write(0)\n") ;

        break ;

    case 8000: // at 8sec

        Molish_Write(0);    

        print("\tMolish_Write(0)\n") ;

        break ;

    case 10000: // at 10sec

        Sample_Write(1);

        print("\tSample_Write(1)\n") ;

        Test_Tube_Write(1);

        print("\tTest_Tube_Write(1)\n") ;

        break ;

    case 19000: // at 19sec

        Molish_Write(0);

        print("\tMolish_Write(0)\n") ;

        break ;

    }

}

void measure(uint32_t time)

{

    if (time % 1000) { // measure only each 1sec => ((time % 1000) == 0)

        return ;

    }

    /*SENSOR LM35*/

    ADC_StartConvert();

    ADC_IsEndConversion(ADC_WAIT_FOR_RESULT);

    entero = ADC_GetResult32();

    ADC_StopConvert();

    voltaje = ADC_CountsTo_mVolts(entero);

    temp = ((voltaje/10.00)-07.00);

    sprintf(str,"%.1f",temp);

#if USE_UART

    print("Temp:") ;

    print(str) ;

    print("\n") ;

#else

    LCD_I2C_setCursor(6,1);

    LCD_I2C_print(str);

#endif

}

int main(void)

{

    uint32_t time = 0 ;

    uint32_t delta = 1 ; /* time resolution 1ms */

    CyGlobalIntEnable;

    I2C_Start();

#if USE_UART

    UART_Start() ;

#else

    LCD_I2C_start();

#endif

    Opamp_Start();

    ADC_Start();

#if USE_UART

    // print("Temp:") ;

#else

    LCD_I2C_setCursor(0,1);

    LCD_I2C_print("Temp:");

#endif

    for(;;)

    {

        relay(time);  

        measure(time) ; /* measure every 1sec */

        time = (time + delta) % 31000 ; /* 0 ~ 30999 = 31 sec cycle */

        CyDelay(delta) ;

    }

}

===============================

And the TeraTerm log was something like

Attached is my test project done with PSoC Creator v4.2.
