The nrf52 have 3x SPI master/slave with EasyDMA ,Can use the 3 SPI simultaneously to write data to ram with EeayDMA?

Hi:Nordic

Because  the nrf52832 can't read 8bit parallel data from GPIOs to RAM with EeayDMA . So I want to use  3 SPI simultaneously to write data to ram  with EeayDMA, can do it  ?thanks!

Hi,

Yes, this should be possible. As described in the documentation, all EasyDMA instaces will act as AHB bus masters, and a peripheral can also implement multiple EasyDMA instances.

The SPI instances will get prioritized access to the bus as described in the documentation.

Best regards,
Jørgen
