说明：  ds1302时钟驱动程序，已在quartus上验证可以是直接使用(DS1302 clock driver, which has been verified on quartus, can be used directly)

1、FSMC全称是静态存储控制器，用来高速操作外部SRAM，NOR，NAND等，广泛用来驱动LCD MCU的FSMC配置在fsmc_nor.c，你也可以查阅相关资料。 2、此例程通过读写外部M29W128，熟悉FSMC的配置以及操作。(1, FSMC stands for static memory controller for high-speed operation of external SRAM, NOR, NAND, widely used to drive the LCD MCU FSMC configuration in fsmc_nor.c, you can also access to relevant information. This routine by reading and writing external M29W128 familiar with the configuration and the operation of the FSMC.)
