SPI frequence

[xianke]

I want to get the work frequence of spi to 16M;How to achieve it?

Use SPIM3 on nRF52840 and be sure to read the errata sheet - SPIM3 has some DMA bugs.

Hi,

I see you tagged the question with nRF52832. This chip supports max. 8M on SPIM. For faster clocks, you need to use SPIM3 on the 52840 as Turbo suggested.
