Enumeration Type Documentation

BmsStatus

enum class BmsStatus : uint8_t

strong

BMS status.

Represents the current state of the Battery Management System (BMS).

Enumerator
NoMsg	No message received from BMS
Waiting	BMS is in standby, waiting to start HV
Starting	BMS is starting high voltage
Started	BMS has started high voltage
Unused	Unused status code

Definition at line 50 of file Enums.hpp.

CarStatus

enum class CarStatus : uint8_t

strong

Main car status state machine.

Represents the current state of the car in the startup and drive sequence.

Enumerator
Init	Just started the car
Startin	Driver holds "Start" button and full brakes (transition state)
Bussin	Buzzer active, driver can release "Start" and brakes (transition state)
Drive	Ready to drive, Drive mode LED on, throttle enabled

Definition at line 19 of file Enums.hpp.

McpIndex

enum class McpIndex : uint8_t

strong

MCP2515 instance indices.

Used to identify different MCP2515 CAN controller instances.

Enumerator
Motor	Motor CAN MCP2515 instance
Bms	BMS CAN MCP2515 instance
Datalogger	Datalogger CAN MCP2515 instance

Definition at line 65 of file Enums.hpp.

PedalFault

enum class PedalFault : uint8_t

strong

Pedal fault status codes.

Represents the current fault status related to pedal input.

Enumerator
None	No fault detected
DiffStart	>10% difference fault just started
DiffContinuing	>10% difference fault is ongoing
DiffExceed100ms	>10% difference fault exceeded 100ms
DiffResolved	Difference fault resolved
ThrottleLow	Throttle pedal below lower threshold
ThrottleHigh	Throttle pedal above upper threshold
BrakeLow	Brake pedal below lower threshold
BrakeHigh	Brake pedal above upper threshold

Definition at line 32 of file Enums.hpp.

StatusCanId

enum class StatusCanId : canid_t

strong

CAN message IDs for status and brake debug.

Used for sending car status and brake messages over CAN bus.

Enumerator
CarMsg	Debug: car status message
StaCarChangeMsg	Debug: car status change message
BrakeMsg	Debug: brake status message
BmsMsg	Debug: BMS status message
HallSensorMsg	Debug: Hall sensor message
