Hi,
I hope someone can help me with my goal. I want to include my infrarot sensor value in the stabilizer.c file for reaching that the sensor values enable the motor. I have include the parameter to enable the motors abd I have the driver from the sensor.

my sensor driver

Code: Select all

#include "deck.h"

#include "log.h"

#include "FreeRTOS.h"
#include "timers.h"

static xTimerHandle timer;
static float range;




void SensorValue(xTimerHandle timer)
{
   range=analogRead(DECK_GPIO_TX2);
}

void mySensorInit(DeckInfo *info)
{
  pinMode(DECK_GPIO_TX2,INPUT); 

  
  timer = xTimerCreate("irsensorTmr", M2T(100), pdTRUE, NULL, SensorValue);
  xTimerStart(timer, 100);
}

static const DeckDriver mySensor_driver = {
  .name = "myIrSensors",

  .usedGpio = DECK_USING_TX2,
  .init = mySensorInit
};

DECK_DRIVER(mySensor_driver);


LOG_GROUP_START(myIrSensors)
LOG_ADD(LOG_FLOAT, range, &range)
LOG_GROUP_STOP(myIrSensors)

what should i do that my range variable is defined in stabilizer.c?

What i would suggest is to define a global variable that holds the value that you want transmitted. So in your sensor driver code add

float dat;

dat will contain the relevant data. Next add a function that returns the required data

float getData()
{
return dat;
}

define this function in the header file of your driver

Then include the header fine in the stabilizer.c file and call the getData function.

Let me know if you have understood this method

Vivek

Thank you very much for your help!
I understand your point and i have tried to include it.
I type this in the driver:

Code: Select all

float dat;
dat=5;
getData(dat);

This is my header.h file:

Code: Select all

float getData(dat)
{
return dat;
}

I included the header in both files.

but i get this error:
