这是我做项目时的一个NX25P40(FLASH)芯片测试程序。相信对做单片机开发需要大容量FLASH的朋友有帮助。该测试程序采用keil51开发，完全通过测试。-This is a project of a NX25P40 (FLASH) chip testing procedures. SCM do believe that the development of large-capacity Flash needs friends h

这是C8051F020单片机读、擦、写串行EEROM芯片M25P40(4M)的驱动程序。全部为自己根据25p40的datasheet编写的，都能够成功使用。M25P40容量大，价格便宜，SPI接口，与8051单片机接口方便。-this is the driver of C8051F serial MCU to the EEROM chip M25P40.

基于C8051f340单片机的Flash芯片25p40存储程序完整版，自己对照pdf手写，测试通过。-Flash-based microcontroller chip 25p40 C8051f340 store the full version of the program, their control pdf handwriting test.
