howr to improve the throughput of USART1 of STM32L431 transmitting the ISM330ISN DATA ?

[JohnGe]

I set the CTRL1_XL (10h) of ISM330ISN  as 0xA4  ,so the ODR of ISM330 is 6667Hz. 

If I want transmit the whole data @6667Hz to external RS485 ，How tocontroll it ？

Can I Using the ISM330 INT1 to trigger every transaction ？  or   independently transmit data using timer of

 STM32L431CCT6？

Hi @JohnGe ,

Welcome to ST Community!

I would suggest to send more data with a single communication, so the best way would be to use the FIFO, save a certain number of data and then send every data with a single UART communication. As an easier version, you could also try to use the normal interrupt and use a custom FIFO inside your code where you store all the data and then send it in a single comm every once in a while.
