Problems solved by technology

[0004] 1. The sensing signal must be converted by the indicator module, and then transmitted to the system side by the embedded microcontroller for subsequent actions, which makes the data processing process too complicated, so the data processing must take a long time
[0005] 2. The indicator module must have a microprocessor, random access memory and read-only memory to perform data conversion. Therefore, the indicator requires a high cost
[0006] 3. Under the structure of traditional indicator processing data, the embedded microcontroller only provides the function of transferring data, and has no other purpose, which wastes the resources of the embedded microcontroller itself

Embodiment Construction

[0046] figure 2 It is a block diagram of an indicator data processing system according to an embodiment of the present invention. Please refer to figure 2 , the indicator data processing system 200 includes an indicator 210 , an embedded microcontroller 220 and a transmission interface 240 . The pointer 210 is electrically connected to the embedded microcontroller 220 and communicates with the embedded microcontroller 220 through the transmission interface 240 . And the pointer 210 has a sensing element 211 for receiving the first sensing signal.

[0047] Therefore, when the user uses the pointer 210 , the sensing element 211 will receive the first sensing signal and store the first sensing signal in the pointer 210 . The embedded microcontroller 220 then reads the first sensing signal stored in the pointer 210 through the transmission interface 240 and converts the first sensing signal into a second sensing signal.

[0048] In this embodiment, the pointer 210 uses a reg...

Abstract

A data processing system of indexer is prepared for receiving a sensing signal by sensing element in indexer and storing received signal in said indexer, receiving said sensing signal by embedded microcontroller and using embedded microcontroller to transmit converted signal to system end after said sensing signal is converted to be signal being able to be received by system end.

Description

technical field [0001] The present invention relates to an indicator data processing system and method, and in particular to an indicator data processing system and method for processing data and converting formats through an embedded microcontroller. Background technique [0002] Due to the rapid development of the electronic industry, portable electronic devices are becoming more and more popular. However, since input devices such as a mouse and a keyboard cannot be carried conveniently, a pointer (Touch Pad) has been developed as an input device. figure 1 System block diagram for data processing of traditional indicators. figure 1 It includes an indicator module 110 , an embedded microcontroller (EC: embedded controller) 120 , a system terminal 130 , a first transmission interface 140 and a second transmission interface 150 . The indicator module 110 includes a sensing element 111 , a processor 112 , a RAM 113 and a ROM 114 . When the sensing element 111 in the pointer...
