[ART-Pi] Smart home based on LD3320-662763A

Overview

Nowadays, there are more and more smart homes, and the devices are gradually becoming smarter.

This extended version uses voice interaction to realize the opening and closing of smart curtains or the lifting and lowering of clothes drying racks.

The LD3320 chip is a "speech recognition" dedicated chip.

This chip does not require any external auxiliary chips such as Flash, RAM, etc. It can be directly integrated into existing products to achieve functions such as voice recognition/voice control.

SYN6288 Chinese speech synthesis chip is a mid-to-high-end speech synthesis chip launched by Beijing Yuyintianxia Technology Co., Ltd. with higher cost performance and more natural effect.

SYN6288 receives the text to be synthesized through an asynchronous serial port and implements text-to-sound (TTS) conversion.

L298N can drive DC motors and stepper motors. (L298N is isolated from the power supply of the expansion board).

All references are ordinary IO ports. Except what is necessary. Does not affect secondary development.

Due to insufficient free time, there is no time to fix the display screen and WIFI, so the above functions are realized. LD3320 has a support package in RT-Thread Studio, which can be used after calling it. The voice broadcast is to transmit data through the serial port, step by step The motor is driven by L298N, and the IIC screen displays it. That's basically it. I didn't study RT-Thread in depth enough. I just studied it briefly, but I still support the domestic operating system very much.

If I have time, I will update it slowly and add all the subsequent ones, such as 7-inch screen, WIFI, and 42mm motor, and replace it with a better solution. I am a newbie, still studying hard. . . Come on - little rookie!

About IIC general reading and writing program
I have been studying the reading and writing of IIC bus recently. Taking 24LC64 as an example, I wrote a Verilog routine. There is no problem with byte reading and writing or page reading and writing.
