nrf52840 as SPI slave (using 52832 main code )

[hmw]

I tried using nrf52832(as slave) communicate with stm32, it successed .

But when I changed nrf52832 to nrf52840 to do the same thing, it failed .

I use the nRF5_SDK_15.0.0_a53641a ,I confirm that the pins have changed

And use nRF5_SDK_15.0.0_a53641a\examples\peripheral\radio\transmitter\pca10040 for nrf52832, ....\pac10056 for nrf52840, and use the arm5_no_packs's keil project

Where I need to modify it?

Can I just change using pca10040 to using pac100056 folder when I change the board?

this picture is stm32(right) send data to nrf52832(left), you can see that it successed

this picture is stm32(right) send data to nrf52840(left),and it failed

you can see that nrf52840 had go into spi IRQ, but it didn't receive anything from stm32.

Hi,

This depends on the code you have used for the SPI slave peripheral. In general, the drivers should work for different boards/chips, as long as the correct variant is set in the project preprocessor symbols, etc. If you have written your own drivers, or are interfacing the registers directly, it may need some modifications.

Can you share the project/code you are using?

Best regards,
Jørgen
