Detailed description

No detailed description exists yet for this component

Examples

The CAN component works together with the injector component to allow you to decode a CAN message ID into a meaningful command.

Example File CAN_Example1 When a key on the keypad is pressed the CAN components transmits a CAN packet.

The CAN packet is decoded by the injector component to give us a meaningful log on the console window.

High Level CAN Data Console

Low Level CAN Data Console

Reference from CAN Injector to ID decode file, $(srcdir) refers to the current project directory.

Demo CAN ID file File:CANID.csv

Macro reference

GetConsoleHandle

	GetConsoleHandle
Gets the handle to the console allowing data displaying on the panel etc.
- BYTE	HandleIndex
Selects which console handle to obtain - 0=ID/Data 1=ID Meanings
- HANDLE	Return

InitialiseInjector

	InitialiseInjector
Sets up the injector ready to receive commands or send data
- STRING	InjectorName
Name of the console that will be created
- BYTE	Return

RxByte

	RxByte
Attempt to receive a byte back from the injector 0 - 255 = Valid data 256 = RX timeout no data available
- UINT	Return

TxByte

	TxByte
Puts a byte onto the comms channel. CAN packet is inserted into injector like this: ID3, ID2, ID1, ID0, D7, D6, D5, D4, D3, D2, D1, D0, \n
- BYTE	DataByte

- VOID	Return

Property reference

	Properties
	CAN Injector Settings
	Circular Buffer Size
Number of bytes that can be held in the injector's circular buffer
	Termination Character
Used to signify the end of a message, in the case of CAN it will end a specific identifier message
	CSV ID File
Location of comma seperated ID description file. e.g. ID,Description 1,Door Open 2,Door Closed 3,Window Open 4,Window Closed 1023,System Disable 1024,System Enable
