LIS2HH12 MEMS Digital Output Motion Sensor is an ultra-low-power high-performance three-axis linear accelerometer belonging to the "pico" family. It has full scales of ±2g/±4g/±8g and is capable of measuring accelerations with output data rates from 10Hz to 800Hz. The self-test capability allows the user to check the functioning of the sensor in the final application. The LIS2HH12 has an integrated first-in, first-out (FIFO) buffer allowing the user to store data in order to limit intervention by the host processor. The LIS2HH12 is available in a small thin plastic land grid array package (LGA) and it is guaranteed to operate over an extended temperature range from -40°C to +85°C.

Hello, we use this chip to measure the inclination angle. Under wide temperature conditions, the angle drift is large. I would like to know some methods of temperature compensation.

What is the temperature range you tested? Compare the data sheet to see if the temperature drift is within the nominal range, then measure the drift at different temperatures and the consistency of multiple devices. Use the temperature sensor inside the sensor for temperature compensation

Thanks!

The operating temperature is between -40 and +65 degrees. Consistency is a problem. After testing several pieces, the general trend of change is similar, but there is no obvious pattern to compensate.

The TCSo in the manual is 0.01%/degC. Check if your temperature drift is within this range. If so, you can record the drift at different temperatures and do linear interpolation based on the current temperature and previous records when using it.

OK, thanks!

Hello, I am working on this thing now, but after downloading, there is no i2cMEMS H and HW CONFIG configuration files, and I can't compile. How to deal with it? Thank you

Hello, the code in lis2hh12_STdC.rar can be used normally after simple modification on the STM32 platform

Where are the i2cMEMS H and HW CONFIG errors you mentioned?

The prompt during compilation is that an error occurs when compiling STM32, and the H files for these two points cannot be found

yjjng posted on 2020-3-24 10:21 When compiling, it prompts that an error occurs when compiling STM32, and these two point H files cannot be found

cannot open source input file "I2C_MEMS.h" This is the prompt, because these two H files are included in the example main program. Thank you, I am working on it, but I don't know how to deal with it

Is this the routine you use?

littleshrimp posted on 2020-3-24 11:24 Are you using this example? lis2hh12_STdC.rar

Yes, this is the routine used

littleshrimp

yjjng posted on 2020-3-24 11:32 Yes, use this routine

Why don't I see the "I2C_MEMS.h" code you mentioned in this example?

littleshrimp posted on 2020-3-24 11:35 Why don’t I see the “I2C_MEMS.h” code you mentioned in this example?

Yes, these two files are included in the main program of EXample. You can output data only when you call them in the main program. Thank you.

yjjng posted on 2020-3-24 11:37 Yes, in the main program EXample, these two files are included. You can output data only when you call them in the main program. Thank you

Which specific file, line number?

I used the DEMO file downloaded from our forum.

Or can you provide me with a project file that will not compile with errors? STM32F4 or F1 is fine. Thank you.

I sent you the project generated using stm32cubemx, and then configured the I2C import corresponding file and you can use it
