# Sixth Lichuang Electric Competition# Offline voice control infrared remote control based on CI-1122

* 1. Introduction to project functions

The PWM port of the module is designed to be connected to an external speaker, microphone, infrared transmitter and receiver circuit, and the voice commands are burned into the chip through self-set voice commands to control the work of each module with voice.

*2. Project attributes

This project is made public for the first time and has not participated in other competitions or been used for school defense.

* 3. Open source agreement

Use GPL 3.0 agreement, not for commercial use

Please fill in during the competition stage↓

*4. Hardware part

The application circuit is divided into main control chip circuit, power input circuit, night light interface circuit, infrared receiving and transmitting circuit, microphone interface, and speaker interface circuit;

Pay attention to adding protective capacitors and resistors in the 5V voltage network, and use voltage division to make each component work within the appropriate voltage range; pay attention to adding diodes in the microphone and speaker interface circuits to prevent reverse connection.

PCB design pays attention to the placement of components and the integrity of the network. For paths carrying large currents, increase the line width appropriately.

Note: It is recommended to use Lichuang EDA . If you choose other EDA tools, please upload schematics in PDF format, PCB drawings in PDF format, and PCB files in Gerber format in the attachments. Here you can explain in detail your project implementation principles and mechanisms, precautions, debugging methods, testing methods, etc. It is recommended to introduce your ideas to others in the form of pictures and texts.

*5. Software part

First, follow the tutorial to set the wake words and command words, as well as the corresponding instructions, and replace the language model, acoustic model, etc. in the template; and use the eclipse development kit equipped with the Qiyin Tai Lun CI1112 module to modify the template code ; After compilation, generate firmware and burn it to realize voice control.

*6. BOM list

*7. Video demonstration

Due to the problem that the firmware cannot be burned, the demonstration cannot be performed temporarily. It will be added after the problem is solved.
