<p></p> <p><b>New page</b></p><div>== Synopsis ==<br /> '''Name:''' SetCallBack<br /> <br /> '''Minimum usb8x version:''' 0.11<br /> <br /> Sets the system callback address<br /> <br /> === Inputs ===<br /> * DE: Address of callback routine<br /> <br /> === Outputs ===<br /> * ''None''<br /> <br /> === Destroys ===<br /> * BC, HL<br /> <br /> == Notes ==<br /> If you are using [[../AutoSetup|AutoSetup]] or any of the internal driver initialization routines (e.g. [[../Mouse/MouseInit|MouseInit]]) you do not need to use this routine because those routines will set the callback address for you. However, if you are setting up the device manually using [[../SetupInPipe|SetupInPipe]], then you should use this routine to setup a callback to handle incoming data.<br /> <br /> If you are accessing usb8x from an application, the callback routine must be located in RAM. If you initialized the U_CALL interface using U_CALL_INIT, then a callback wrapper to call the routine you passed to U_CALL_INIT has already been created for you. You can reference it as ''USBDriverCall+offCallBack''.</div>
