Variable Documentation

◆ dw3000_params

const dw3000_params_t dw3000_params = DW3000_PARAMS

static

Configuration struct.

The patched decadriver by br101 only allows a single device, with the benefit of reducing the code size and the reasoning that typical embedded devices will only ever use one DW3000 radio. Thus only a single params struct is allowed here.
