Writing to Multiple SPI Devices in Parallel

[Omer Farooq]

Hi, 

    We have a requirement to connect a SPI device to each SPI interface present on nRF52840, and we want to write to those multiple devices in parallel. Is there any API available they could let us write to those SPI devices connected to different SPI interfaces in parallel? You answer will be highly appreciated.

Best regards,

Omer

One idea is to use nrfx_spim_xfer() in non-blocking mode.

One more thing can nrfx_spim_xfer() in parallel write different data to different SPI instances? Please also point me to the API documentation.

No but you can call this function multiple times and thus let it run in parallel. API is on the infocenter.
