Workflow using a wired mouse: LED (light-emitting diode) – optical lens – desktop – an optical sensor (SENSOR) – a master control chip (MCU) – a USB interface – Computer monitor Coordinate
When the mouse moves, the optical sensor constantly collects each point on the desktop; the collected points are sent to the master control chip for memory, and the bit difference is compared to the next point; the master control chip compares the signal converted into the corresponding interface information transmitted to the computer, allowing the cursor to move up and down.
LED (light) – desktop – optical lens – optical sensor (SENSOR) – master control chip (MCU) – RF IC – antenna sending – antenna receiving – RF IC – USB master chip – USB cord – Screen coordinates on a PC.
When the mouse moves, the optical sensor continuously collects each point on the desktop, sends the collected point position to the master control chip for memory, and compares the next point of the big difference, the master control chip compares the displacement signal converted to the corresponding interface information through the RF IC modulation into a wireless carrier signal through the wire transmit out, and the receiver receives the corresponding wireless carrier sign. The necessary interface information is sent to the USB master control chip, which converts it into a USB signal and sends it to the computer through the USB cable, allowing the cursor to move up and down.
