Error Event Code List

Error Event Codes

This page lists all error event codes with more in-depth descriptions than can be found in the Phidget22 API.

These codes are passed to an error event handler. See the Phidget22 API documentation for your device to see which error event codes are supported. The error event codes are generic, and the error description passed to the error event handler may contain more detailed information about the actual cause of the error event.

Name	Value	Description	Details
BADVERSION	Hex: 0x01 Dec: 1	Version Mismatch	Client and Server protocol versions don't match. Ensure that both sides are using the same release of phidget22.
BUSY	Hex: 0x02 Dec: 2	Phidget in Use	The Phidget device channel has already been locally attached. Only one channel may attach locally to a device channel.
NETWORK	Hex: 0x03 Dec: 3	Network Error	An error occurred with the network communications. You can use the getDescription method of the error event to get more information.
DISPATCH	Hex: 0x04 Dec: 4	Dispatch Error	An error occurred when trying to dispatch an event. It's possible that the data rate is too fast for the computer (or network) and the event queue has filled up.
FAILURE	Hex: 0x05 Dec: 5	General Failure	A general failure occured - see description for details.
OK	Hex: 0x1000 Dec: 4096	Error Cleared	An error state has ended. You can use the getDescription method of the error event to get more information.
OVERRUN	Hex: 0x1002 Dec: 4098	Sample Overrun	Sampling overrun. Some samples were lost in firmware because the queue filled up. This error is exclusive to Phidget InterfaceKits.
PACKETLOST	Hex: 0x1003 Dec: 4099	Packet Lost	One or more packets were lost. This error is often an indication that your event handlers are not executing fast enough. Try to remove slow processes like GUI updates or user input from your handlers.
WRAP	Hex: 0x1004 Dec: 4100	Wrap-Around	Variable has wrapped around. A variable has wrapped. For example, the encoder position can wrap from 2,147,483,647 to -2,147,483,648 because of an integer overflow.
OVERTEMP	Hex: 0x1005 Dec: 4101	Over-Temperature	Over-temperature condition detected. You can use the getDescription method of the error event to get more information.
OVERCURRENT	Hex: 0x1006 Dec: 4102	Over-Current	Over-current condition detected. You can use the getDescription method of the error event to get more information.
OUTOFRANGE	Hex: 0x1007 Dec: 4103	Out of Range	Out of range condition detected. You can use the getDescription method of the error event to get more information.
BADPOWER	Hex: 0x1008 Dec: 4104	Bad Power	Power supply problem detected. You can use the getDescription method of the error event to get more information.
SATURATION	Hex: 0x1009 Dec: 4105	Saturation	Saturation condition detected. A sensor's value has reached the maximum or minimum of its sensing range. For example, a 1000 lux light sensor will throw this error event when a value greater than 1000 lux is detected.
OVERVOLTAGE	Hex: 0x100b Dec: 4107	Over-Voltage	Over-voltage condition detected. Occurs in power-providing Phidgets when the output voltage exceeds the set value. You can use the getDescription method of the error event to get more information.
FAILSAFE	Hex: 0x100c Dec: 4108	Failsafe	Failsafe condition detected.
VOLTAGEERROR	Hex: 0x100d Dec: 4109	Voltage Error	Voltage error detected. A voltage error occurs when a Phidget that provides a voltage output has the value drop below what what specified. This can happen if the device being powered draws too much current, which causes a voltage drop. Stay within output current specifications to avoid voltage errors.
ENERGYDUMP	Hex: 0x100e Dec: 4110	Energy Dump	Energy dump condition detected. An energy dump occurs when a power-providing Phidget needs to dissipate its extra energy. See the User Guide for your device for more information.
MOTORSTALL	Hex: 0x100f Dec: 4111	Motor Stall	Motor stall detected. Occurs when a dangerous motor stall is detected. You can use the getDescription method of the error event to get more information.
