Lis2dh App Scanrate and Speed of Lis2dh

[Stv]

Hello Ladies and Gents,

I have following Problem with my App:

The Scanrate from given Timer can be in min. 10ms. These ist f=1/0,010=100Hz.

 

So If I configure the Lis2dh to normal or Highres Mode I have a f=1.344 KHz

 

Anybody have an Idea how to increase/decrease the Scanrate to geht all the values of interval?

Also I'm bind to USB and the Transactiondelay from max 500ms.

Hi @Stv ,

Welcome to ST Community!

Regarding the timer scanrate, I don't know how to increase or decrease the frequency (it could be a question for the STM32 section, if it involves an STM32).

However, you can bypass this problem using the FIFO of the sensor: you activate the FIFO with the ODR at 1344Hz, and you read all the queue when the timer triggers.
