Description
Technical field
The utility model belongs to electronic technology field, relates to controller, especially relates to a kind of touch screen controller.
Background technology
Along with social progress and development in science and technology, human lives's present stage, most people is not only satisfied with safety to the demand of inhabitation and life area, comfortable, clean and tidy basic function is supporting, more wishes that residing environmental energy experiences fashion, edifying and the enjoyment of the artistic breath of aestheticism, and can have a small and exquisite exquisiteness at the gold starting point within reach 86 box height on wall, the air-conditioner controller that does not lose again brief fashion is that no one is ready to refuse substantially.On wall, air-conditioner controller is along with the introducing of capacitance touch technology, make us realize the perforate on front panel that is confined to of having broken away from mechanical key on original function basis, expose keycap and pressed, on the complete panel of a monoblock, realize all demonstrations and operation, and need not worry the life-span of mechanical key and the water proof and dust proof of tapping.On the smooth panel of a monoblock, we also more easily place element attractive in appearance, design the brief air-conditioner controller of atmosphere.For this reason, people have carried out long-term exploration, have proposed various solutions.Although also designed various touch screen controllers, mostly exist complex structure, communication interface is difficult to the technical matterss such as satisfied use is required, and job stability is not good.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, simple in structure, the touch screen controller of good operating stability.
For achieving the above object, the utility model has adopted following technical proposal: this touch screen controller, it is characterized in that, this controller comprises core CPU circuit, on core CPU circuit, be connected with conduct electricity road, infrared receiving circuit, capacitance touch button circuit, external EEPROM, backlight and buzzer drive circuit, JTAG of communicating circuit, temperature and turn SWD circuit and display interface circuit, on described external EEPROM, be connected with reserve battery, described core CPU circuit is connected with power circuit.
In above-mentioned touch screen controller,, described power circuit comprises DC-DC lowering and stabilizing blood pressure output module and LDO lowering and stabilizing blood pressure output module.
In above-mentioned touch screen controller, described communicating circuit comprises independently RS485 communicating circuit of two-way, is connected with TVS protection structure and UART interface on RS485 communicating circuit.
In above-mentioned touch screen controller, described capacitance touch button circuit comprises the sample circuit of 10 spring buttons, and described capacitance touch button circuit is connected with core CPU circuit by SPI interface circuit.
Compared with prior art, the advantage of this touch screen controller is: reasonable in design, simple in structure, there is highly versatile, rich interface, the feature such as job stability is high, and antijamming capability is strong.
