JQ6500 φωνητική ενότητα MP3 ενότητα MCU σειριακή ανακοίνωση ελέγχου 1 έως 1 5-Way Control Music IC

-This module uses SPI FLASH, is measured in bits, hard disk is measured in bytes, 8bit = 1byte, 16Mbit = 2Mbyte is equivalent to the computer display 2M, please buy customers to distinguish between good capacity

-Function:
1. Support sample rate (KHz): 8/11.025/12/16/22.05/24/32/44.1/48
2. 24-bit DAC output, dynamic range support 90dB, signal-to-noise ratio support 85dB
3. Fully support FAT16, FAT32 file system, large support for 32G TF card, support for 32G U disk, 64M bytes of NORFLASH
4. Multiple control modes, parallel port control mode, serial port mode, AD key control mode
5. Broadcast language interrupt function, can pause the background music being played
6. Audio data sorted by folder, supports up to 100 folders, every other folder can be assigned 1000 songs
7. 30 levels of volume adjustable, 10 levels of EQ adjustable
8. Spi flash can be plugged in, connected to the computer can display the disk of spi flash to update the content
9. You can control the playback of specified music through the serial port of the microcontroller
10. In key mode, you can choose the playback mode: interruptible, non-interruptible, single song cycle, big cycle (interruptible: that is, in the process of playback, press the key will interrupt the current state to perform new; non-interruptible: that is, in the process of playback, press any key is invalid until the end of playback of the current track to be effective)
