MiniSTM32F103 Development Board V3 Version
The purpose of the experiment is:
Learn the use of VS1053 and implement a simple MP3.
Hardware resources:
1, DS0 (connected to PA8)
2. Serial port 1 (baud rate: 9600, PA9/PA10 connected on board USB to serial chip CH340)
3, ALIENTEK 2.8/3.5/4.3/7 inch TFTLCD module (driven by GPIO, connection relationship see lcd.h)
4, W25Q64 (SPI FLASH chip, connected to SPI 1)
5. Keyboard KEY0 (PC5)/KEY1 (PA15)/KEY_UP (PA0, also known as WK_UP)
5, SD card, connected by SPI1
6. The connection relationship between ATK-VS1053 module and STM32 chip is as follows (please connect Mini board and MP3 module according to the following wiring):
ATK-VS1053 Module - ----- STM32 Chip
VS_SCK------------- PA5
