Is there a way of capturing 8 GPIOs and transfer data to easydma

[Antonio]

Simultaneously, as a way of a parallel bus, using an extra one as a input clock, and save the byte in easydma, without CPU intervention?

Either in the nRF52832 or nRF52840?

Thanks!

No. (making the answer >10 bytes long)

Thanks for the quick answer :)

 how  read  the parallel bus of GPIO's input data to ram in  easydma,as Antonio asked?

Hi

As Jan replied there is no way to do this in the nRF52 series unfortunately. 

There is no EasyDMA feature in the GPIO peripheral. 

The only way I can think of that might work is to connect an external GPIO extender chip, and connect it to the nRF52 device over SPI. Then you can use the EasyDMA feature of the SPI interface.
