TM4C123GE6PM: Sending float sensor readings via UART

Is there a reason it didn't get into TivaWare ?

Hello Shai,

I was just saying there isn't a 'printFloat' function in TivaWare. That code I posted is straight out of SensorLib examples in TivaWare.

I tried to use the code as follows:

int32_t i32IntegerPart = 0 ;
int32_t i32FractionPart = 0 ;

        // Get the new accelerometer and gyroscope readings.
        MPU6050DataAccelGetFloat(&g_sMPU6050Inst, &fAccel[0], &fAccel[1], &fAccel[2]);
        MPU6050DataGyroGetFloat(&g_sMPU6050Inst, &fGyro[0], &fGyro[1], &fGyro[2]);
        //
        // Convert the floating point ambient temperature  to an integer part
        // and fraction part for easy printing.
        //
        i32IntegerPart = (int32_t)fAccel;
        i32FractionPart = (int32_t)(fAccel * 1000.0f); // Error in this line
        i32FractionPart = i32FractionPart - (i32IntegerPart * 1000);
        if(i32FractionPart < 0)
        {
            i32FractionPart *= -1;
        }
        UARTprintf("Ambient %3d.%03d\t", i32IntegerPart, i32FractionPart);

I get an error on the saying: 

#32 expression must have arithmetic type main.c /PID line 189 C/C++ Problem

Hello Shai,

Make sure you include math.h:

#include <math.h>

Added it - still the same message...

My bad,
I forgot that "fAccel" is an array.
I changed:
i32FractionPart = (int32_t)(fAccel * 1000.0f);
to:
i32FractionPart = (int32_t)(fAccel[0] * 1000.0f);

And now it compiles.
I'll test to see if it works.
