nRF52832 spi frequency

[zxcv7063]

Hi:

   nRF52832  SDK17.1.0\examples\peripheral\spi\pca10040 , Is the maximum frequency of the SPI in here only 8M?  

   The following screenshots:

   

   Can't the frequency be set to higher ?   Such as 20M , 30M .

   thanks !

zxcv7063,

Yes, the maximum SPI clock frequency can be 8MHz. Refer to datasheet page # 421. I am attaching the screenshot below as well.

Thanks.

Hi:

  Thank you for your reply . 

  Our project application needs 20M, how should we modify it?

Hi:

   Spi and I2C cannot be used together ?  The following screenshots:

   

  

   cannot use peripherals with the same ID ?  

   How to solve this problem  ?

This is correct, as written in the Shared Resources section of each peripheral's datasheet.

You can use these peripherals together so long as you do not use the particular instances with the same ID. In order to use SPI and TWI, you will have to use TWI0 and SPI1, or visa versa, for example. Essentially, you can not use both TWIM1 and SPIM1 concurrently.
