Front End Module Voltage Detection#

APIs for configuring and detecting a voltage from a Front End Module (VDET).

The rail_util_vdet plugin lets customers measure an output voltage from their attached Front End Module at a specific time in a Tx packet. This information allows optimizations to power configuration, and monitoring FEM performance.

Note

  • VDET is only supported with EFR32XG25 devices.

Enumeration Documentation#

RAIL_Vdet_Mode_t#

RAIL_Vdet_Mode_t

VDET Modes.

The VDET Mode is passed to RAIL_ConfigVdet() via RAIL_VdetConfig_t. The Front End Module Voltage Detection (VDET) Utility allows customers to measure their Front End Module performance at specified points in the Transmit packet.

Enumerator
RAIL_VDET_MODE_DISABLED

VDET is completely disabled.

RAIL_VDET_MODE_AUTOMATIC

VDET_AUTOMATIC causes VDET measurements to be taken every Tx packet at the specified time.

RAIL_VDET_MODE_IMMEDIATE

VDET_IMMEDIATE causes an immediate VDET measurement.

RAIL_VDET_MODE_COUNT

A count of the choices in this enumeration.

RAIL_Vdet_Resolution_t#

RAIL_Vdet_Resolution_t

VDET Resolution for the AuxADC.

The VDET Resolution is passed to RAIL_ConfigVdet() via RAIL_VdetConfig_t. Shows available resolution options.

Enumerator
RAIL_VDET_RESOLUTION_10_BIT

~10 bit resolution.

RAIL_VDET_RESOLUTION_11_BIT
