Rocker bar position detecting circuit, gamepad and game equipment

Abstract

The invention discloses a rocker bar position detecting circuit, a gamepad and game equipment. The rocker bar position detecting circuit comprises a comparison module and an MCU. The first input end of the comparison module is connected with a movable contact of an X-axis potentiometer of a rocker bar. The second input end of the comparison module is connected with a movable contact of a Y-axis potentiometer of the rocker bar. Two X-axis level output ends and two Y-axis level output ends of the comparison module are all connected with the MCU. A voltage across the first input end of the comparison module is compared with two different reference voltages, and results are output to the MCU. A voltage across the second input end is compared with the two different reference voltages, comparison results are output to the MUC. The MUC determines the current X-axis position and Y-axis position of the rocker bar according to level signals output by the two X-axis level output ends and level signals output by the two Y-axis level output ends. According to the technical scheme, the cost of the gamepad adopting the rocker bar position detecting circuit is reduced.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a rocker position detection circuit, a game handle and game equipment. Background technique [0002] In recent years, the game market has become more and more popular. In addition to professional game consoles such as Xbox and PSP, TVs, mobile phones, boxes and other products have also integrated many game platforms to provide users with a variety of smooth playing experiences, followed by games. The accessories are diversified, and the most widely used one is the game controller. The game controllers of Microsoft’s Xbox and Sony’s PSP game consoles are recognized by the industry as two directions of game controller design, so most of them on the market are of this type. Similar designs for both types of gamepads. [0003] At present, all gamepads have joysticks (that is, direction control keys), and most gamepads also have two joysticks, and each joystick has two analog out...

Problems solved by technology

This way of detecting the position of the rocker requires the microprocessor to have multiple interfaces with AD conversion functions. At the same time, the microprocessor needs to have a built-in AD conversion module, which has high requirements for the microprocessor and the high cost of the microprocessor, which leads to higher cost
