Posted on November 29, 2017 at 11:10LSM9DS1 magnetometer in FAST_ODR mode is said to give output data at greater than 80 Hz. But can we specify this ODR ? What should I do if I want an ODR of 100 Hz ?#magnetometer #odr #lsm9ds1

Posted on December 07, 2017 at 07:03Hi Miroslav,Thanks for the response. However, I have 2 questions.1. Where is this table documented? 2. In LP mode, we expect the ODR to be less since greater ODR means more consumption of power. But this table sh...

Posted on March 24, 2017 at 07:05Hi,Thanks for the code. It works perfectly fine for Line in input and headphone output. However, I noticed that it is not working for speaker output. I tried changing the output device to OUTPUT_DEVICE_SPEAKER as wel...

Can both microphones and Line In audio input channels on STM32F769I DISCO board be used simultaneously for 2 different audio sources?

LSM9DS1 data sheet says that the FAST_ODR mode enables magnetometer data rates higher than 80Hz. How do we specify this data rate?
