Hi Team, I want to learn the i2c features and functions while using STM32F4 Discovery kit based on STM32F411VE and communication with LSM303DLHC. I want to know if there is any deault register selected in LSM303DLHC when no register value is mentioned.

In this for the i2c communication I am planning to use LSM303DLHC for undersatnding the i2c communication and the protocols. I want to learn more about the driver API like i2c_init(), i2c_read(), i2c_read_with_no_register etc.. Kindly suggest me a wa...

LIS2DS12 sampling frequency madness

I was using an ISM303DAC as an accelerometer and everything was fine. Unfortunately, the chip was discontinued, and I had to immediately replace it with LIS2DS12 because all of the accelerometer register configurations were the same. I didn't have to...

Using IIS3DHHC as Inclinometer

Hi,I am using STM32F401VE with IIS3DHHC accelerometer sensor. I wanted to use the accelerometer as inclinometer. Apparently some documents are available with the mathematical formula to convert the accelerometer into inclinometer. However, I was wond...
