DW3000 API and multiple UWB modules on single SPI bus

Wireless Connectivity Ultra-Wideband

Hi,

Glancing over the API docs, it seems that it was built for communication with only a single DWM3000 module on an SPI bus. Can this be changed? For instance, could I have multiple DWM300 modules in the SPI and trigger multiple ranging to a tag?

Thanks,
Jonny

Hi @jonny
you can have multiple SPI device connected to one SPI bus (CLK, MISO, MOSI), but you need to have separate CS line for each SPI device.
