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

Standard 6*8 ascii char dots lib,can be directly used to LCD driver program.

对遥感图像进行大气校正，选择黑暗像元法时需要自动提取黑暗像元，以进行程辐射的计算。同时通过得到的程辐射获得地表真实的反射率。

This is a small program to create indexs for two binary trees and combine them to a new 003 * index tree and output the new tree,the second tree only has the left child tree then 004 * if the first tree has no left child tree,insert the second tree into the first tree as 005 * its left child and if the first tree has the left child tree,then insert the first tree 006 * into the second tree as its left child.
