4.6 USB Host

Hardware Setting

¾Check if 2,3 of J-USB- and J-USB+ short

¾Connect with a USB mouse

Flowchart

The following flowchart illuminates the procedure to implement USB host function, which can catch the position of a USB mouse, it is not a certain flow of a function, but provides a clue to study and understand the sample code.

	Start
SystemInit ( )	Initialize system	Enumeration	USB_Handler ( )
SystemInit ( )	Initialize system
	clock

main ( )	Initialize timer	Mouse data	USBF_Handler ( )
	Initialize timer	process	USBF_Handler ( )
		process	get_mouse_data ( )
			get_mouse_data ( )
minihost_init( )	Init USB host	Display mouse
	Init USB host	data
		data
			Main()

Usage

1)Make the hardware setting

2)Enable definition “Debug” in the code

3)Run the code.

4)Move the USB mouse, and watch the mouse position in the terminal IO window as following figure. (Debug viewer window in Keil IDE)
