Data Structures
struct	uwb_selftest_result
	Self-test result emitted by uwb_min_selftest. More...
struct	uwb_twr_result
	Result of a raw static-STS SS-TWR initiator burst (uwb_min_twr_poll). More...
struct	uwb_twr_frame
	Outcome of one raw SS-TWR POLL/RESP exchange (uwb_min_twr_exchange). More...

Macros
#define	UWB_DW3110_DEV_ID   0xDECA0302u
	Expected DEV_ID value for the DW3110 (the IC on the DWM3000 module).

Functions
int	uwb_min_read_chipid (uint32_t *id_out)
	Read the DW3000-family DEV_ID register over SPI.
int	uwb_min_hw_reset (void)
	Pulse the DW3110 RST line low to force a hardware reset.
int	uwb_min_selftest (struct uwb_selftest_result *out)
	Radio self-test: configure, TX one frame, then arm RX.
int	uwb_min_twr_prep (void)
	Configure the radio for the raw SS-TWR loopback (SP3-ND, ch9, code11); no STS.
void	uwb_min_twr_exchange (struct uwb_twr_frame *f)
	Run one POLL/RESP exchange; the STS must already be programmed.
int	uwb_min_twr_poll (uint32_t n, uint32_t period_ms, struct uwb_twr_result *out)
	Raw static-STS SS-TWR initiator burst (bench probe).
int	uwb_min_radio_init (void)
	Ensure the DW3110 is fully initialised (probe + initialise + configure + LEDs).
uint32_t	uwb_min_radio_generation (void)
	Count of fresh radio inits; changes whenever the base config was re-applied.
