Ds1621 Proteus 样本驱动程序

在嵌入式LINUX下，利用QCOP在进程间通信的实例。通过该实例你可以熟悉QCOP进程间通信机制。-In the embedded LINUX, the use of in-process communication QCOP example. Through the examples you can familiar with the inter-process communication mechanism QCOP.

嵌入式设备使用的FFT算法。基于2基的库里-图基础。 以数据类型，以s32替换float。 误差可控。有误差范围的宏定义决定。 在STM32F103系列CPU上，以72MHz运行，256点，需要不足5ms时间。 算法在数据转移方面还有进一步的优化空间。若使用大型的固定值的查找表，大概还能节省1ms左右。

一个arm7实验板上音频控制测试程序，此音频控制测试程序由c语言编写。-a arm7 experiment on-board audio control test procedures, this test program from the audio control c language.

Perfect Example for Embedded-C begineers Explaining use of Data types, Storage class specifiers. The following code will not immediately run. After being debugged, you are to run this code in the MPLAB environment as outlined in the procedure. This code, when working, will be a very simple program that initializes two variables, runs a loop, and stops. The variables are Fahrenheit and Celsius representing the two common units of Temperature. The loop walks Fahrenheit through all integers between -212.0 and +212.0 while setting the respective Celsius value each step of the way.-Perfect Example for Embedded-C begineers Explaining use of Data types, Storage class specifiers.
