[0029] Embodiment 2 Pointer device operation process

[0030] Figure 7 is description Figure 5 The flow chart of the operation algorithm of the stored program at the sending end of the anti-collision wireless pointer device. Figure 8 is description Image 6 The flow chart of the operation algorithm of the stored program at the receiving end of the anti-collision wireless pointer device. Operations represented by algorithms are performed in a microprocessor corresponding to image 3 The programming instructions sent to FLASH in advance are shown. Each step or decision indicated in these flowcharts may contain one or more steps in the actually executed procedure, and each step is often a complete subroutine in itself. The programming of these steps is familiar to intermediate programmers, so for the sake of simplicity, they will not be described in detail here. In order for each step or decision to be executed, mechanical sequential conditions are specifically require...

Abstract

The invention relates to a multifunctional anti-collision wireless pointer device. The multifunctional anti-collision wireless pointer device comprises a transmitting end and a receiving end, wherein transmitting end input equipment is used for inputting data or commands to a transmitting end device and comprises eight press keys which simulate upward-moving, downward-moving, leftward-moving, rightward-moving, left, right, upward-rolling and downward-rolling press keys of a mouse; an NRF24L01 wireless interface chip 1 of transmitting end output equipment can transmit data to the receiving end which is bound with a wireless channel through the wireless channel with a unique address; the receiving end comprises receiving end input equipment and receiving end output equipment; an NRF24L01 wireless interface chip 2 of the receiving end input equipment receives data or control command transmitted by the transmitting end from the wireless channel which is bound with the receiving end and has the unique address. The multifunctional anti-collision wireless pointer device can realize a page turning function, also can realize the rolling and clicking functions of the mouse, can quickly start a program, has high responsivity and achieves an anti-collision effect with the accuracy rate up to above 99 percent.

Description

technical field [0001] The invention belongs to the field of computers, in particular to a multifunctional anti-collision wireless interactive pointer device for a teacher and a teaching system controlled by a digital computer. Background technique [0002] With the development of communication and computer technology, automation and intelligence have become a part of countless people's lives. The application of these technologies has greatly improved the efficiency of our study and work and the quality of life. For example, in the past, teachers would stand on the podium, hold chalk in their hands, and write down important points on the blackboard for students to understand. Time-consuming and labor-intensive, the dust that chalk produces also endangers health. Now, most schools are equipped with a modern teaching system. Teachers only need to prepare lessons before class, make slides of the lecture content, and copy them to the computer of the teaching system to give vivi...
