BB.Error.Protocol.Feetech.HardwareAlert exception (bb_servo_feetech v0.2.3)

Feetech servo hardware alert error.

Raised when a Feetech servo reports hardware error status flags. The alerts field contains a list of active alert atoms.

Alert Types

:voltage_error - Input voltage out of range
:sensor_error - Magnetic encoder malfunction
:temperature_error - Motor temperature too high
:current_error - Over current detected
:overload_error - Overload protection triggered

Note: Bit 4 in the status byte indicates torque state, not an error.

Summary

Functions

:raw_value

from_bits(servo_id, bits)

@spec from_bits(non_neg_integer(), non_neg_integer()) :: t()

Creates a HardwareAlert from raw hardware error bits.

Bit 4 (torque enabled) is filtered out as it is not an error condition.
