# SPI 控制5302C


## 硬件设置

	[SPI2 Freq: 80000000]
	[SPI2 CSN PE31]
	[SPI2 SCLK PE27]
	[SPI2 MISO PE28]
	[SPI2 MOSI PE30]
	[HANDSHAKE PIN PZ08]


	USB2UART 打印log
	USB0 枚举 USB CDC ACM
	
## 数据流程
	USB0下发AT指令 --> FIFO --> SPI WRITE REQUEST --> SPI READ STATUS --> SPI WRITE DATA --> PTR5302C
						PTR5302C -- >GPIO EVENT --> SPI READ STATUS --> SPI READ DATA --> USB FIFO --> USB ACM
						
## 运行现象

当工程正确运行后，串口终端会输出如下信息：
