Bluetooth is a technology that can achieve short-distance wireless transmission. Today, Bluetooth technology has been widely used in: car Bluetooth devices, Bluetooth eye massagers, etc. In addition to these products we often use, Bluetooth audio chips are also widely used in: It is also gradually widely used in fitness equipment, children’s toys, consumer electronics and other fields.

In today’s electronics market, Bluetooth voice chips have been widely used in various fields. Bluetooth is a technology that can achieve short-distance wireless transmission. Today, Bluetooth technology has been widely used in: car Bluetooth devices, Bluetooth eye massagers, etc.; In addition to these products that we often use, Bluetooth audio chips are also widely used in fitness equipment, children’s toys, consumer electronics and other fields.

Among them, the GY8001-16P series voice chips have attracted much attention due to their excellent performance and diverse functions. In particular, its serial port control modes: pulse counting, key press, one-line serial port, two-line serial port, bring significant advantages to various application scenarios. This article will delve into the application advantages of these serial port control modes.

GY8001-16P is a compact new high-quality plug-in card MP3 module independently developed by Dongguan Geyuan Electronic Technology Co., Ltd. Using GY8001 Bluetooth serial port as the main control chip, it can support dual decoding of MP3 and WAV formats. The module has a built-in TF card holder, which can be inserted into the card to change the voice content; it can also be connected to an external U disk or USB data cable to a computer to change the TF content. This module has a built-in 3W power amplifier and can directly drive 3W speakers, making it more convenient to use.

Product Features

Supports MP3 and WAV high-quality audio format files with beautiful sound.
24-bit DAC output, dynamic range supports 90dB, and signal-to-noise ratio supports 85dB.
Supports one-to-one trigger playback of 15 segments of voice,
The 310 port hardware has 8 trigger modes to choose from, making it more widely used.
Supports UART asynchronous serial port control: supports play, pause, up and down songs, volume increase and decrease, song selection playback, advertising insertion, etc. Built-in volume, track, and EQ
power-down memory functions.
Equipped with a TF (Micro SD) card holder, the card can be inserted to change the voice content, and the maximum support is 32G memory card. Supports reading U disk, up to 32G; you can also directly
replace the contents of TF through USB data cable.
It comes with a 3W power amplifier, which can be directly connected to an external speaker to complete the playback: customers can also connect an external single or dual-channel power amplifier.
Standard 2.54mm pitch DIP16 pin header package, compact and beautiful.

Button trigger instructions

This module has five trigger 0 ports and supports up to 15 segments of button one-to-one trigger playback. Eight control modes can be selected through three 10 ports through a 3.3K resistor connected to ground or not, suitable for a variety of applications.
The resistor for setting the control mode is on the front of the module, marked with ABC characters. The module default value is 010, which can be modified by the customer when they return.
The serial port control protocol GY8001 has a built-in standard UART asynchronous serial port interface, which is a 3.3VTTL level interface. It can be converted into RS232 level through GYX3232 chip. The communication data format is: start bit: 1 bit: data bit: 8 bits: parity bit: none: stop bit: 1 bit. To use the computer serial port debugging assistant, you need to set the serial port parameters correctly.

Audio storage order and naming rules

The sorting in the SD card is based on the order of storage, so make sure the order of saving to the SD card from the computer is correct. So how do we ensure that the storage order is correct? First, we should name and sort the audio files on the computer (modifying the sorting in the SD card is invalid). You can name the audio as 0001XXX.MP3, 0002XXX.MP3, 0003XXX .MP3; then copy and paste the entire selection into the SD card. Be especially careful not to drag it in with the mouse, because this is related to the operating system of the computer. Whichever song the mouse arrow is on will be stored in the SD card first, so it is easier to mess up. This is very important.

Application areas

Industrial control field: industrial, control equipment;
Intelligent transportation equipment: toll stations, parking lots, and in-car voice prompts;
Advertising industry: advertising slogan broadcast;
Access control, attendance: voice prompts such as the door is open;
