24 * @brief The type signature for a function to handle a custom OpenXC command.
26 * @param[in] name - the name of the received command.
27 * @param[in] value - the value of the received command, in a DynamicField. The actual type
28 * may be a number, string or bool.
29 * @param[in] event - an optional event from the received command, in a DynamicField. The
30 * actual type may be a number, string or bool.
31 * @param[in] signals - The list of all signals.
32 * @param[in] signalCount - The length of the signals array.

38 * @brief The structure to represent a supported custom OpenXC command.
40 * @desc For completely customized CAN commands without a 1-1 mapping between an
41 * OpenXC message from the host and a CAN signal, you can define the name of the
42 * command and a custom function to handle it in the VI. An example is
43 * the "turn_signal_status" command in OpenXC, which has a value of "left" or
44 * "right". The vehicle may have separate CAN signals for the left and right
45 * turn signals, so you will need to implement a custom command handler to send
46 * the correct signals.
48 * Command handlers are also useful if you want to trigger multiple CAN messages
49 * or signals from a signal OpenXC message.
