Principle of work is:

The U1 chip be with realize a plurality of USB interface can both be independently and the PC USB interface to carry out the I/O communication be purpose.It is a kind of latest model high speed USB controller, and that select here is the CY7C65013 that 48 pin Surface Mount CYPRESS companies produce, and it uses the 12M crystal oscillator.Insert when 4 USB expansion interfaces have peripheral hardware, by the data of D-, D+, when clock line enters controller, program can be carried out it timesharing, classification, difference ground with it by the PC USB interface data communication of serial, high speed.The C1 here, C2, C11, C12, C13, C14, C15 are that filter capacitor, resistance R 17～R32 are control D-, D+ current potential and current-limiting resistance.USBCON0 is the USB interface that links to each other with PC, and USBCON1～4 are the USB interface that links to each other with peripheral hardware.

The U2 chip is to gather, to judge because D-, D+ mouth and the U1 of the serial data that the signal saltus step that three optoelectronic switch D1, D2, D3 and three button S1, S2, S3 change generation produces by USBCON11 carries out a kind of USB controller that communication is a function.Here we also select the another kind of new controller CY7C63722 that CYPRESS company produces.Here D1, D2, D3 are that optoelectronic switch, each switch produce the signal of two variations.Represent two opposite directions.Utilize the rotation number of light tooth to produce the variables corresponding number, and carry out the variation of cursor position.Three button S1, S2, S3 control the variation of three keys in left, center, right respectively.Here resistance R 4～R9 plays clamping action, and R2, R3 play metering function to luminotron, and when the optoelectronic switch conducting, corresponding input pin current potential is high, drags down because of R4～R9 resistance eutral grounding when closing.

The effect of U3 chip mainly be to 4 Flash store, delete, operation such as format.It is controlled and operates U5, U6, four Flash of U7, U8 by control line CLE, R/B, WP, PRE and address wire A12～A15, and 8 data lines are also linked on the U4 chip when connecting 4 Flash, carry out exchanges data respectively.Because that we select for use is the Flash of 4 2Gbit, so 4 data that Flash can store 1Gbyte.Here we select for use U3 is 8051 single-chip microcomputers.The function of U4 chip is that 8 parallel bit data are converted into the serial data that can carry out quick communication.USBD+, USBD-mouth and U1 by USBCON21 carry out data communication.We select for use U4 is the PDIUSBD12 controller that Philips company produces.Its transmission speed is faster, and the D1 light emitting diode is the control pilot lamp.When data were carried out communication, it did not stop flicker, when bright and when not dodging for treating mode of operation.Chip U9 is a level transferring chip, transfers 5V to 3.3V and power supply is provided for CPU and Flash.SW1 and SW2 are the toggle switchs for selecting different storage spaces to be provided with, and when SW1, SW2 change, according to the judgement of CPU program, and select the number of Flash, and capacitor C 1, C2, C5, C7, C8, C15, C16 strobe here.R1, R2, R3, R4 play voltage clamp position and current limliting.8051 adopt the electrification reset mode, and C6 is a reset capacitance.
