which libraries allow us to use this functions?

bode miller

hello guys, i wan't to explain in my project which library i use for some functions, for example to read data from MPU9150 which is on sensor hub

MPU9150DataAccelGetFloat

MPU9150DataGyroGetFloat

MPU9150DataMagnetoGetFloat

void

MPU9150I2CIntHandler(void)

and for this is it #include "driverlib/rom_map.h"?

ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_I2C7); ROM_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOD);

ROM_GPIOPinConfigure(GPIO_PD0_I2C7SCL);

ROM_GPIOPinConfigure(GPIO_PD1_I2C7SDA);

I2CMInit ?

i gues for this

GPIOPinTypeI2CSCL(GPIO_PORTD_BASE, GPIO_PIN_0);

ROM_GPIOPinTypeI2C(GPIO_PORTD_BASE, GPIO_PIN_1);

we use #include "driverlib/rom_map.h"

Hello Bode

Could you please explain your question a bit more? I actually could not even find a plain question in your post.

Hello Bruno,

Well for function for example MPU9150DataGyroGetFloat there was added some library or header file, i want to know which library/header files are added to use functions above :)

If I understand your goal correctly, and it's not entirely clear what that goal is, then you should get a copy of doxygen. It will generate call (and inheritance) graphs even w/o markup. It does require another program or two to provide support for generating the graphs.

in start of program i use #include files, so i want to know which include is for functions above

Bode,

As a general rule, the answer to "which file needs to be included so that I can use a certain function" must be provided by the documentation of the library you are trying to use.

In this particular case, you should open the manual, which is the file "SW-TM4C-SENSORLIB-UG-2.1.4.178.pdf"

Your question is answered in chapter 16:

Bruno

hello Bruno,
yes thanks! I found that files which allow to use main functions in program for mpu9150 are in sensorlib and driverlib library.

Hi Bode,
It seems you edited out your other question, about the sensor rate...
Briefly: a "big" number like 2000 degrees per second will provide less resolution than a small number like 250 degrees per second. So you should only use big numbers if your object is expected to rotate that fast. Think that 1 full turn is 360 degrees, and to spin at 2000 per second, you'd have 5 full turns in that time - which is already faster than a power screwdriver, for example.
