nrf52840 I2S打开读取数据，会占用全部资源 When nrf52840 I2S is opened to read data, it will occupy all resources

[xingye123]

When I2S reads the digital audio sensor, when strat is turned on_ After I2S, the data can be read and recognized normally, but this action takes up the whole CPU occupancy rate, and other functions such as broadcast buttons can't work. I don't know what's going on for a long time, so I ask the gods to answer

Hi,

 

The peripheral itself uses DMA for transferring, so it should not be blocking the CPU.

How are you handling this in your application?

 

Kind regards,

Håkon
