本例程实现了msp430afe系列30位ad的采集，已实验通过。

程序对一张24位的bmp图加入油画效果，然后生成新的bmp图。（注：必须是24位的bmp图才能做运行！）

bmp图片24位转32位

将24位BMP文件转换成8位灰阶图像 机器视觉开发

将24位彩色bmp转为灰度图的C程序源代码，编译后即可执行。 使用方法：（假设编译后可执行文件命名为bmp_utils） bmp_utils -h <打印帮助> bmp_utils -p bmp_file <打印图像信息> bmp_utils -c bmp_file <转换为灰度图>

24位BMP图片转565格式16位数组C文件代码，生成的代码用于嵌入式程序代码中图片文件显示，BMP图片以数组的形式保存并读取

4-Channel, Low Noise, Low Power, 24-Bit, Sigma-Delta ADC with PGA and Reference
