Dear All,
I need your help because I created a PCB with the nrf52840 and a flash connected exactly as the one on the dev-board.
The only difference is that the one on...
I am using nrf52840 . I am sending data 2 bytes as FF .I put the data in 2d array like this. char dataSend[1][5]={"FF"}; This char dataSend has 1 row and 5 length .This should...
I need transfer data to/from NRF52840.
I see I can do it by using function nrfx_usbd_ep_transfer - but don't see any examples.
I want to make bulk endpoint and be capable...
