Author : X.PONCET
Version : 1.00
Description : This class manage the USBtin CAN gateway.
- Serial connexion management
- CAN connexion management, with some basic command.
- Receiving CAN Frame and switching then to appropriate CAN Layer
- Sending CAN Frame with writeframe, writeframe is virtualized inside each CAN Layer
Supported Layer :
* MultiblocV8 CAN : Scheiber sp�cific communication

History :
- 2017-10-01 : Creation by X.PONCET

- 2021-04-03 : Increse m_USBtinBuffer size from 15 frames to 128 frames to avoid frame loss of Can frames
