Hi All,

I am trying to change compiler options in Eclipse and was wondering how to do this? I am hoping to add -mfloat-abi=soft.

Thank You,

George

in your makefile.mk file add the following line:

C_FLAGS += -mfloat-abi=soft

Still getting a "undefined reference to `__aeabi_i2f'"...

Any suggestions on why?

I added the line to the project makefile. It doesn't seem like it is including it in the make/gcc command because if I change it to something wrong it doesn't give me a makefile error.

Well, I tested the C_FLAGS issue myself with the ample project hello_sensor from the WICED Smart SDK 2.1.1.

If I add the following bad compiler flags to makefile.mk within the folder hello_sensor

C_FLAGS += -xxxxxx

and do a build in Eclipse I get the following output:

arm-none-eabi-gcc: error: language xxxxx not recognized

arm-none-eabi-gcc: error: language xxxxx not recognized

arm-none-eabi-gcc: error: language xxxxx not recognizedarm-none-eabi-gcc: error: language xxxxx not recognized

arm-none-eabi-gcc: error: language xxxxx not recognized

arm-none-eabi-gcc: error: language xxxxx not recognized

make[1]: *** [../../build/hello_sensor-BCM920736TAG_Q32-rom-ram-Wiced-release/sparinit.o] Error 1

make: *** [hello_sensor-BCM920736TAG_Q32] Error 2

So the C_FLAGS do make it to the make tool.

Please note that you have to make a clean build whenever you modify the makefile.mk.

To see what compiler flags are used you can add the following to the make parameters:

VERBOSE=1

This is what I am getting out after adding the:

C_FLAGS += -mfloat-abi=soft

Any thoughts on why it isn't compiling?

Strange. Looks like the C_FLAGS do not make it to your compiler.

If I compile the hello_sensor.c with the additional C_FLAGS in the makefile.mk I do get the following output:

So the -mfloat-abi=soft does make it to GCC in my case.

Can you please try it as well with the standard hello_sensor project?

Btw: Have a look at the following thread: Floating-Point Arithmetic

Ya, I have. It uses a third-party library which seams more trouble-prone to me but open to suggestions on this...

I was able to get hello sensor to compile with the soft-float flag enabled AND disabled (simply taking it out, so maybe it is enabled by default?). I was able to do this after adding a float data type and confirming a variety of the float operators work. I then added the failing piece of code from my custom project to hello_sensor. This is where the issue lays:

The lines (bolded) where the local floats are multiplied by the global integers caused the issue. When I brought the globally declared integers into PID_Logic() it all worked--again, with or without the 'C_FLAGS += -mfloat-abi=soft' line in the make file.

//PID code by:http://coder-tronics.com/pid-tutorial-c-code-example-pt2/

  int d_Temp = 0;             // This stores the old ADC value

  int i_Temp = 0;             // This stores the accumulated Integral value

  int PWM_Temp = 166;         // Given an initial value, after that just stores the old value for calculation

void PID_Logic()

   {

    //Local variables for PID

     float Kp = 0.01;      // The value for Proportional gain

     float Ki = 0.01;      // The value for Integral gain

     float Kd = 0.0001;    // The value for Differential gain

   

    int Set_Point = 353;    // The ADC reference point we are aiming to regulate to

    int iMax = 100;         // Used to prevent integral wind-up

    int iMin = -100;        // Used to prevent integral wind-up

    int Err_Value;          // Holds the calculated Error value

    int P_Term;         // Holds the calculated Proportional value

    int I_Term;         // Holds the calculated Integral value

    int D_Term;         // Holds the calculated Differential value

    int new_ADC_value;      // Holds the new ADC value

    int PWM_Duty;           // Holds the new PWM value

    // More efficient to read this once and store as used 3 times

    new_ADC_value = 0;//read_ADC();

    Err_Value = (Set_Point - new_ADC_value);

    // This calculates Proportional value, Kp is multiplied with Err_Value and the result is assigned to P_Term

    P_Term = Kp * Err_Value;

    // Prepare Integral value, add the current error value to the integral value and assign the total to i_Temp

    i_Temp += Err_Value;

    // Prevents integral wind-up, limits i_Temp from getting too positive or negative

    if (i_Temp > iMax)

    {i_Temp = iMax;}

    else if (i_Temp < iMin)

    {i_Temp = iMin;}

    // Calculates the Integral value, Ki is multiplied with i_Temp and the result is assigned to I_Term

    I_Term = Ki * i_Temp;

    // Calculates Differential value, Kd is multiplied with (d_Temp minus new_ADC_value) and the result is assigned to D_Term

    // The new_ADC_value will become the old ADC value on the next function call, this is assigned to d_Temp so it can be used

    //D_Term = Kd * (d_Temp - Err_Value);

    d_Temp = Err_Value;

    /****** Now we have the P_Term, I_Term and D_Term *****/

    PWM_Duty = PWM_Temp - (P_Term + I_Term + D_Term);

    // PWM overflow prevention

    if (PWM_Duty > 300)

    {PWM_Duty = 300;}

    else if (PWM_Duty < 30)

    {PWM_Duty = 30;}

    // Adjusts the PWM duty cycle

    //adjust_PWM(PWM_Duty);

    // Assigns the current PWM duty cycle value to PWM_Temp

    PWM_Temp = PWM_Duty;

   }

Does anyone know why this is?

I have a work around so it isn't a blocking issue but want to know the root-cause.

Hi gmelcer,

what's your work around?

Can you please share?

thanks.

Hi Roger,

I run a small product design firm called BoxUnfolded (www.boxunfolded.com) so our work changes. One of the more recent projects we did was GoKey which you can check out here:

indiegogo.com/projects/gokey-charger-cable-locator-memory-all-on-your-key-ring

If you scroll down on the updates section you can see pictures of some of the work we did. We handle hardware design, firmware, and app in-house. We partner for other aspects of the design.

Best,

George
