Error messages

This is a list of the possible error messages and their meanings. All error messages begin with the text ERROR_ and then some terse descriptor of the error. In most cases, the input that triggered the error message is returned. A single “:” is used as the delimiter when the input is appended.

ERROR_AI_PIN_NOT_AVAILABLE:input

The specified pin number is not available for analog input on this hardware.

ERROR_AI_PIN_NOT_WATCHED:input

The specified pin number was not set up for averaging. Need to call !ai:mean pin 1 to enable averaging on this pin.

ERROR_BINARY_RANGE:input

The value must be either 0 or 1.

ERROR_BI_PIN_NOT_AVAILABLE:input

The specified pin number is not available for binary (digital) input on this hardware.

ERROR_BO_PIN_NOT_AVAILABLE:input

The specified pin number is not available for binary (digital) output on this hardware.

ERROR_BUFFER_OVERFLOW

Too many characters were received before the line terminator. All characters received so far will be discarded.

Some Arduinos do not have much available RAM. The current buffer length is 40 characters.

ERROR_COMMAND_FORMAT:input

All commands must have at least one space separating the baseCmd from the pin number. This command is generated when no space is detected in the input.

ERROR_DIGITAL_PIN_NOT_AVAILABLE:input

The specified binary (digital) pin number is not available on this hardware.

ERROR_PIN_NOT_PWM:input

The specified pin is not supported for PWM on this Arduino hardware. This is determined by calling the Arduino system macro digitalPinHasPWM(pin) which is defined for each different type of Arduino hardware variation.

ERROR_NOT_IMPLEMENTED_YET:input

The command specified has not yet been implemented.

ERROR_PWM_RANGE:input

The PWM value must be between 0 and 255, inclusive. This error is reported for any value outside this range.

ERROR_TOO_MANY_ARGUMENTS:input

The general form for input commands is baseCmd pin [value] where baseCmd is given in the table above, pin is an integer appropriate for the chosen hardware interface, and value is only used for “!” (set) commands.

At this time, if value is specified for a “?” (read) command, it is ignored. In the future, this will generate an error message.

ERROR_UNKNOWN_COMMAND:input

The input was not recognized as a valid command. One reason for this might be the use of upper case. Other possibilities exist.
