SPI returning 0xFFF... (custom pcb) (Solved)

Wireless Connectivity Ultra-Wideband

Solved!

There were two problems :

  1. I used a weak pull-down on nCS
  2. I forgot that the DW1000 acts as half-duplex logic wise.

There is still this weird issue with the data being received a few samples late, but that’s nothing major.
