summary:
WT2003HM04 is a powerful high-quality product Voice module High performance 32-bit processor is adopted, and the maximum frequency can reach 120MHz. It has the characteristics of low cost, low power consumption, high reliability, and strong versatility, and can have a built-in 900 second voice capacity. Flexible control mode: support UART control mode; Support 1-wire serial port and 2-wire serial port control mode; Support key control mode (key control mode requires micro customization). Each control mode has been fixed before delivery, and the sample needs to be confirmed with our business personnel first.
Product features:
1. UART control mode: standard UART communication interface, default baud rate 9600; SPI Flash is supported as storage. It has the functions of file index play, insert, single track cycle, all track cycle, random play, etc. The 32 level volume can be adjusted, and the maximum support for external 128Mbit Flash;
2. One line serial port control mode: voice play, stop, loop play and volume can be controlled through the code sending end; The 8-level volume can be adjusted, and SPI Flash can be used as memory: the maximum external 128 Mbit Flash can be supported;
3. Two wire serial port control mode: voice playback, stop, loop playback and volume can be controlled through the code sending end; The 8-level volume can be adjusted, and SPI Flash can be used as memory: the maximum external 128 Mbit Flash can be supported;
4. Key control mode: the trigger mode is flexible, and any key can be set at will as pulse repeatable trigger, pulse non repeatable trigger, invalid key, level maintaining non recyclable, level maintaining recyclable, level non maintaining recyclable, previous song non recyclable, next song non recyclable, previous song recyclable, next song recyclable, volume+, volume -, play/pause, stop There are 15 trigger modes such as play/stop, and up to 10 keys can be used to trigger the control output;
5. Power on does not play by default; With BUSY status indication, BUSY is low level at ordinary times and high level at play;
6. Support switching audio output mode, sample default SPK output, if DAC output is required, please refer to audio output switching command;
7. It supports high-quality voice audio format, MP3 and WAV format, (audio code rate supports 8kbps~320kbps) and beautiful voice;
8. Working voltage: 2.4-5.2V;
9. Built in 0.5W Class D power amplifier;
10. Two 16 bit asynchronous frequency divider timers;
11. Digital audio stream, IIS supports host and slave modes;
12. An infrared remote control decoder;
13. 16 bit high-precision ADC and DAC;
14. High power IO drive capability, up to 64mA can be directly driven;
15. When a single chip is used (using the built-in capacity), the built-in voice needs to be written before leaving the factory.
16. Support UART update program and voice. It is recommended to reserve UART serial port when drawing board. Please refer to serial port upgrade document for upgrade.
17. M04 module has no burning project, and the burning project version needs to be confirmed before shipment. For details, refer to the following selection table
18. Support SD card/USB flash disk offline upgrade program. It is recommended to reserve an interface when drawing board;
19. If the voice chip needs flash. Flash produced by "Weichuang" must be used. If it is not used for special reasons, it must be handed over to our company and noted. (It will not work because you use the flash of other home without permission)
