Raspberry Pi connection with DWM1000 IC

Does anyone can help me with how to connect the raspberry pi GPIO pins to the DWM1000 uwb IC?
and how to interface it with SPI for UWB connection of 2 raspberry pi?

Hi @Kudz
you need to connect SPI lines + reset + IRQ pins between DWM1000 and RPi. You can power the DWM1000 direct from the RPi’s 3.3V pins.

Regarding interfacing one DWM1000 to two RPIs - it is doable with a bigger effort but I would not recommend to do that. SPI bus interface is not meant to be used over wires (but it will work) and you need to synchonise reset handling between RPi’s. What is your use case?

Thanks, I was going to build a project to demonstrate wireless video streaming using raspberry pi with camera and DWM1000 for transmitter and raspberry pi with lcd screen and DWM1000 for receiver. Just want to how to connect them to work together?

Hi @Kudz
so you wan to connect 2x DWM1000 to single RPi? If so then the DWM1000 can share SPI lines (MISO/MOSI/CLK) but rest of the lines must not be shared!!! Otherwise it would not work.

Hi @leapslabs
there will be two raspberry pi and two dwm1000 transceiver.

  1. Raspberry pi + dwm1000 as transmitters
  2. Raspberry pi + dwm1000 as receiver
