Problems with pow() function in CubeMX project Posted on June 20, 2016 at 08:59
Hello,
I have wrote program to read data from ms5611 barometer for my F0Discovery board and i have two problems with it.
First I need to convert pressure read by uC into alitude. To read real altitude i using code shown below:
uint32_t ms5611RealPressure(I2C_HandleTypeDef *hi2c)
{
uint32_t pressData = 0;
uint32_t tempData = 0;
int32_t realPress = 0;
int32_t dT = 0;
int32_t TEMP = 0;
int64_t OFF = 0;
int64_t SENS = 0;
pressData = ms5611PresTempRead(hi2c, pressure, UHIGH); //odczyt cisnienia RAW
tempData = ms5611PresTempRead(hi2c, temperature, UHIGH);
dT = tempData - (promData[4] * pow(2,8));
TEMP = 2000 + dT * (promData[5] / pow(2,23));
OFF = (promData[1] * pow(2,16)) + (promData[3] * dT) / pow(2,7);
SENS = (promData[0] * pow(2,15)) + ((promData[2] * dT) / pow(2,8));
realPress = ((pressData * (SENS / pow(2,21))) - OFF) / pow(2,15);
return realPress;
}
and it's work fine.
For convert i
