The design puts forward a multi - channel SPI Flash Controller which use STM32F103ZET6 as nuclear microprocessor and which use GPIO pins to simulate eight groups SPI timing to control reading, writing and erasing of eight Flash chip at the same time , and have a man - machine dialogue through the graphical user interface. The experimental results show that the design can be used to control eight Flash chips effectively.%提出了一种以STM32Fl03ZET6为核心微处理器的多通道SPI Flash控制器,采用GPIO口模拟8组SPI时序控制8个flash芯片同时进行读、写、擦除,并通过图形用户界面进行人机对话.实验结果表明该设计可实现对8个Flash芯片的有效控制.
