spi pins in nrf52840

[Balu Varkala]

Hi,

Can you please provide the SPI pins for nrf52840 chip.

or else should i connect any GPIO signal?

[Jørgen Holmefjord]

Hi,

Any GPIO can be used, but you should avoid the pins marked with "Standard drive, low frequency I/O only" in the Pin assignments specifications.

Best regards,
Jørgen

Hello,

Thank you..!

Should i use below signals as SPI signal .

P0.17  -- CS

P0.26 -- SCK

P0.20 -- DIO0/SI

P0.04 -- DIO1

P0.22 -- DIO2

P0.06 -- DIO3

 

Kindly suggest ASAP.

[Jørgen Holmefjord]

Yes, those are not marked as "Standard drive, low frequency I/O only". Are you planning to use QSPI?

[Balu Varkala]

Yes. As of now am not planning to use QSPI.. if i use is there any issues?

[Jørgen Holmefjord]

No issue, I was just asking since you only mention SPI is the original post, while the pin-connections indicate QSPI usage.

[Balu Varkala]

Yes. I am  planning to use QSPI
