How to send data to pc incontinuously via HID?

Song Kevin

I study the KEIL HID demo for MCB2300, the demo is fine but not fit me.

My project need read data from LPC23xx if the data is prepared. but the demo always continously send report to PC even the data does not prepare.

I dont know how to modify the code to implement this function.

I test the MOUSE and KB,the mouse moving data are sent to PC incontinuously via HID(the data just send when the mouse is moving or clicking). but the KB is continously send data to PC(the data send even no key is pressed).

Can anyone give me some advice ? in MCB2300,if I press the key INT0, the HID send data to PC otherwise no data send.

Thanks
