Does nrf52dk emulation of nrf52810 support non fpu environment?

[MnP_Junho]

Hi

We currently working on nrf52 dk with SDK15.0.0 but we will use nrf52810 rather than nrf52832 due to cost.

As I know, nrf52810 doesn't have FPU compared to nrf52832 and we should check computation time or cost in nrf52810 chip.

There is an guide emulating nrf52810 on the nrf52832(nrf52dk) but I'd like to know whether the emulation also supports non fpu environment or not.

Thanks.

Yes - one of the things specifically mentioned in the guide is about not using the FPU !

EDIT

Ah - that was one of the things missing from the guide!

They said it would be updated. The Infocentre is no longer maintained - have you checked on the new  documentation library ?

There is no way to emulate longer SPIM/TWIM MAXCNT registers. If you want to utilize these features, you need to use nRF52840 DK or a custom board/DK with nRF52810. If you do not use longer SPIM/TWIM transfers than 255 bytes, there is no need to care about this.
