Detailed Description
As shown in fig. 1 and fig. 2, a circuit compatible with 2.4G remote control and infrared remote control includes a 2.4G remote control receiving module, an infrared receiving module, and a switch Q1, wherein a first input end of the 2.4G remote control receiving module is connected to an antenna, a second input end of the 2.4G remote control receiving module is connected to an output end of the infrared receiving module, an output end of the 2.4G remote control receiving module is connected to an input end of an FB-IR network and is connected to a main control GPIO chip through the FB-IR network, an input control end of the switch Q1 is connected to a control end of the 2.4G remote control receiving module, a first end of the switch Q1 is connected to an output end of the infrared receiving module, a second end of the switch Q1 is connected to an input end of the FB-IR network, and an input control end of the switch Q1 controls connection between the first end and the second end.
The transistor Q1 is a transistor, a base of the transistor is an input control terminal of the transistor Q1, an emitter of the transistor is a first terminal of the transistor Q1, and a collector of the transistor is a second terminal of the transistor Q1.
The 2.4G remote control receiving module comprises a 2.4G remote control receiving chip U1 adopting the model of AK801AE-S1 and peripheral circuits thereof.
The infrared receiving module adopts an infrared receiving head IR1 with the model number of ARM-583A-L-M and a peripheral circuit thereof.
In this embodiment, the FB _ IR network is connected to a main chip GPIO, and the switching transistor Q1 selectively switches data received by the infrared receiver IR1, so as to implement GPIO sharing and solve the problem of data collision when GPIO is shared by 2.4G remote control and infrared remote control.
Specifically, the 2.4G remote control receiving chip U1 receives a 2.4G remote control signal through the antenna ANT1, decodes the signal therein, and outputs a remote control command through the 6 pins, and when no remote control command is output, the 6 pins are at a high level.
The infrared receiving head IR1 receives 38KHz infrared light and amplifies the signal internally, when there is 38KHz carrier signal, it outputs low level at 1 pin, otherwise it is high level state.
IR _ H is the data output of IR1, high when IR1 has no data output, and is connected to pin 12 of 2.4G remote control receiver chip U1. When the infrared receiving head IR1 receives data, there is a falling edge as the start signal, and the 2.4G remote control receiving chip U1 will determine whether it is outputting 2.4G remote control command after receiving the falling edge. When the 2.4G remote control receiving chip U1 is not outputting the 2.4G remote control command at this time, the pin 8 of the 2.4G remote control receiving chip U1 outputs a high level to turn on the transistor Q1, otherwise, the pin 8 of the 2.4G remote control receiving chip U1 outputs a low level to turn off the transistor Q1. When the triode Q1 is turned on, the data of the infrared receiving head IR1 can be sent to the GPIO of the main control chip, and when the triode Q1 is turned off, the infrared remote control data are cut off, so that normal 2.4G remote control data receiving cannot be influenced.
When the 2.4G remote control receiving chip U1 needs to output the decoded remote control command, it is first determined whether the IR receiving head IR1 is receiving data at this time. If the IR receiver IR1 is receiving data at this time, the 2.4G remote control receiving chip U1 will delay outputting the remote control command at pin 6 and keep pin 8 outputting high level, otherwise, the transistor Q1 will be turned off at pin 8 outputting low level, so as to avoid being interrupted by the IR receiver IR1 when the 2.4G remote control receiving chip U1 outputs the remote control command.
In the embodiment, the 2.4G remote control and the infrared remote control can be shared by only using one master control chip GPIO, the problem that the master control chip GPIO is not enough is solved, the conflict of data receiving between the master control chip GPIO and the infrared remote control can be avoided, the same set of coding rules of the 2.4G remote control and the infrared remote control can be realized, and software upgrading is not needed.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
