在深入了解Flash存储器的基础上,采用单片机自动检测存储器无效块。主要通过读取每一块的第1、第2页内容,判断该块的好坏,并给出具体的实现过程,以及部分关键的电路原理图和C语言程序代码。该设计最终实现单片机自动检测Flash坏块的功能,并通过读取ID号检测Flash的性能,同时该设计能够存储和读取1GB数据。 Abstract: On the basis of in-depth understanding the Flash chips,this paper designs a new program which using the SCM to detect the invalid block.Mainly through reading the data of the first and second page to detect the invalid block.Specific implementation procedure was given,and the key circuit schematic diagram and C language program code was introduced.This design achieved the function of using the MCU checks the invalid block finally,and increased the function by reading the ID number of Flash to get the performance of the memory.And the design also can write and read1GB data

自制51编程器 I have build my own programmer. This device can program the AT89C51 and works with it. So it can easily be adapted to programming other devices by itself. The Atmel Flash devices are ideal for developing, since they can be reprogrammed easy, often and fast. You need only 1 or 2 devices in low cost plastic case for developing. In contrast you need 10 or more high cost windowed devices if you must develop with EPROM devices (e.g. Phillips 87C751).

FLASH文件系统的源码,Flash memory is a nonvolatile memory, which allows the user to electrically program (write) and erase information. The exponential growth of flash memory has made this technology an indispensable part of hundreds of millions of electronic devices. Flash memory has several significant differences with volatile (RAM) memory and hard drive technologies which requires unique software drivers and file systems. This paper provides an overview of file systems for flash memory and focuses on the unique software requirements of flash memory devices.

The W78E58B is an 8-bit microcontroller which has an in-system programmable Flash EPROM for firmware updating. The instruction set of the W78E58B is fully compatible with the standard 8052. The W78E58B contains a 32K bytes of main ROM and a 4K bytes of auxiliary ROM which allows the contents of the 32KB main ROM to be updated by the loader program located at the 4KB auxiliary ROM 512 bytes of on-chip RAM four 8-bit bi-directional and bit-addressable I/O ports an additional 4- bit port P4 three 16-bit timer/counters a serial port. These peripherals are supported by a eight sources two-level interrupt capability. To facilitate programming and verification, the ROM inside the W78E58B allows the program memory to be programmed and read electronically. Once the code is confirmed, the user can protect the code for security

Among the many features built into Microchip’sEnhanced FLASH Microcontroller devices is the capability of the program memory to self-program. This very useful feature has been deliberately included to give the user the ability to perform bootloading operations.Devices like the PIC18F452 are designed with a designated“boot block”, a small section of protectable program memory allocated specifically for bootload firmware.
