Finally I got it working properly. Reading SDcard was very awesome for me for first time, so I decided to make a library for STM32F4xx devices and post it to my website. It’s basically just communication interface between STM32F4 and FatFS library by Chan. It supports SPI or SDIO communication. Library also supports USB communication, but for that purpose you need USB stack too. USB is available here

stm32f4xx包含启动文件（starup_stm32f4xx.s,system_stm32f4xx.h,system_stm32f4xx.c,system.h)和库函数(stm32f4xx intialize files and library)

自己写的spi_flash的驱动，利用stm32管脚模拟的方式，是学习理解spi总线良好资料，将sd卡挂载的fatfs中的文件（字库）进行读写，并显示到屏幕上，奋斗板的同学试一试(Way the own written spi_flash drive, take advantage of the the stm32 pin analog, to the spi bus good information to learn to understand, read and write to the sd card in mount the fatfs of files (fonts), and displayed on the screen, the students struggled board give it a try)

说明：  MC9S12XEP100整车控制器方案，包含c源文件，原理图，通信协议等，可以进行二次开发。(MC9S12XEP100 vehicle controller scheme, including c source file, schematic diagram, communication protocol, etc., can be secondary development.)

ADI公司的AD4111是具有±10V和0 mA至20 mA输入和明线检测功能的低功耗 24 位 Σ-Δ ADC,集成了模拟前端(AFE),还集成主要模拟和数字的信号调理区快,为每个模拟输入通路配置成八种单独建立图,最大通路扫描速率6.2 kSPS(161 μs),嵌入的2.5V低漂移(5 ppm/℃)能隙基准电压降低了外接元件数量,单电源5V或3.3V工作,工作温度?40℃ 到 +105℃,主要用在过程控制PLC和DCS模块.本文介绍了AD4111主要特性,功能框图以及评估板EVAL-AD4111SDZ主要特性,框图,电路图,材料清单和PCB设计图.(The AD4111 is a low power, low noise, 24-bit, sigma-deltaanalog-to-digital converter (ADC) that integrates an analog front end (AFE) for fully differential or single-ended, high impedancebipolar,10 V voltage inputs, and 0 mA to 20 mA current inputs. The AD4111 also integrates key analog and digital signalconditioning blocks to configure eight individual setups for each analog input channel in use. The AD4111 features amaximum channel scan rate of 6.2 kSPS for fullysettled data.)
