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.

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

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