ODrive

Attributes

error  —  Error    readwrite

No description

vbus_voltage  —  float32    readonly

Voltage on the DC bus as measured by the ODrive.

Unit: V

ibus  —  float32    readonly

Current on the DC bus as calculated by the ODrive.

Unit: A

A positive value means that the ODrive is consuming power from the power supply, a negative value means that the ODrive is sourcing power to the power supply.

This value is equal to the sum of the motor currents and the brake resistor currents. The motor currents are measured, the brake resistor current is calculated based on config.brake_resistance.

ibus_report_filter_k  —  float32    readwrite

Filter gain for the reported ibus. Set to a value below 1.0 to get a smoother line when plotting ibus. Set to 1.0 to disable. This filter is only applied to the reported value and not for internal calculations.

serial_number  —  uint64    readonly

fw_version_revision  —  uint8    readonly

fw_version_unreleased  —  uint8    readonly

0 for official releases, 1 otherwise

brake_resistor_armed  —  bool    readonly

No description

brake_resistor_saturated  —  bool    readwrite

No description

n_evt_sampling  —  uint32    readonly

Number of input sampling events since startup (modulo 2^32)

n_evt_control_loop  —  uint32    readonly

Number of control loop iterations since startup (modulo 2^32)

task_timers_armed  —  bool    readwrite

Set by a profiling application to trigger sampling of a single control iteration. Cleared by the device as soon as the sampling is complete.

task_times  —  TaskTimes

No description

system_stats  —  SystemStats

No description

user_config_loaded  —  uint32    readonly

No description

misconfigured  —  bool    readonly

If this property is true, something is bad in the configuration. The ODrive can still be used in this state but the user should investigate which setting is problematic. This variable does not cover all misconfigurations.

Possible causes:

• A GPIO was set to a mode that it doesn’t support
• A GPIO was set to a mode for which the corresponding feature was not enabled. Example: GPIO_MODE_UART_A was used without enabling config.enable_uart_a.
• A feature was enabled which is not supported on this hardware. Example: config.enable_uart_c set to true on ODrive v3.x.
• A GPIO was used as an interrupt input for two internal components or two GPIOs that are mutually exclusive in their interrupt capability were both used as interrupt input. Example: <odrv>.<axis>.config.step_gpio_pin of both axes were set to the same GPIO.
