Detailed Description

For a further understanding of the present invention, reference will be made to the following detailed description taken in conjunction with the accompanying drawings and examples. It is to be understood that the examples are illustrative of the invention only and are not limiting.

Example 1

As shown in fig. 1, the present embodiment provides a smart projector, which includes:

the ATJ229R2 main control chip is used for data acquisition and control;

the WIFI chip is used for inputting and outputting data;

the voltage reduction circuit is used for converting the external 5V voltage into the voltage 3.3V required by the chip;

the audio acquisition module is used for converting analog audio acquired by an MIC from the outside into digital signals and outputting the digital signals to the ATJ229R2 main control chip for processing;

the storage module is used for storing programs and data;

a speaker for outputting sound;

the DLP module is used for displaying operation contents; accessing and putting the content to be displayed from NORFLASH to a DLP optical machine for displaying;

the control detection IO module is used for being connected with various external interfaces;

WIFI chip, step-down circuit, audio acquisition module, storage module, loudspeaker, DLP module and control detection IO module all are connected with ATJ229R2 main control chip.

In this embodiment, the WIFI chip is RTL 8188.

In this embodiment, the WIFI chip, the voltage reduction circuit and the ATJ229R2 main control chip are all located on an M229R2 core board.

In this embodiment, the speaker includes two audio output interfaces, standard IIS digital audio and analog audio. This facilitates the connection output to various audio interfaces.

In this embodiment, the control and detection IO module includes a standard TTL level IO interface, an ADC input interface, a UART, a SIRQ interrupt interface, and an IIC interface. This facilitates interfacing with various external interfaces.

In this embodiment, the storage module includes norstack and TFCARD.

After the power-on, the voltage reduction circuit can convert 5V voltage from the outside into 3.3V voltage required by each chip, the ATJ229R2 main control chip can initialize each peripheral after being started, after NORFLASH enables the modules to work normally, the ATJ229R2 main control chip loads a program stored on NORFLASH into a built-in DDR, the operation and the execution are carried out, and after the power-on network is connected, all data are input and output through a WIFI chip.

The ATJ229R2 main control chip obtains audio data through the audio acquisition module, caches to built-in DDR, reaches a certain amount after, and ATJ229R2 main control chip sends the recording data to the server through the WIFI chip and handles, and the server returns different audio files according to gathering different pronunciation, and when ATJ229R2 main control chip broadcast audio file, broadcasts the audio through loudspeaker.
