ZigBee厂商对ZigBee通信模块Jennic JN5139的实例…

本文纤细的介绍了IIC总线原理。并介绍了嵌入式linux驱动的层次结构 -This article introduced the delicate Principle IIC bus. And introduced the embedded linux-driven hierarchical structure

KeilC编译测试通过STM32F103单片机实现的步进电机加减速算法

这是一个可以将OPENcv移植到DSP上的库函数包括CV库等等，比如可以将这个库运用到CCS5.1上，自动生成库LIB也就是EMCV库，这样就可以直接在DSP上直接使用OPENCV函数了，非常方便使用~当然这个库要自己在CCS平台上进行编译

T-Ker测试synchronization_communicationsemaphore部分的tk_cre_sem,tk_del_sem, tk_sig_sem, tk_wai_sem, tk_ref_sem在移植的uT-Engine上运行是否正常。 api的返回值正确与否，在ads上设断点观察，同时用Lpc2104上的LED显示（如果正确，则程序中设定的LED就闪亮）nel中的flag小实验程序-T- Ker test synchronization_communication tk_cre_sem part of the semaphore, tk_del_sem. tk_sig_sem, tk_wai_sem. tk_ref_sem transplantation in the UT-Engine running normal. Api return to the correct value, based on the ads breakpoint observation, Lpc2104 using the LED display (if correct, procedures were set on the flashing LED) nel flag of the small experimental procedure

1）能够输出锯齿波，三角波，正弦波，脉冲波. （2）能根据键盘命令进行波形之间的切换. （3）能对输出的波形频率进行调节。 -1) can output sawtooth, triangle wave, sine wave, pulse wave. (2) according to the keyboard command to switch between waveforms. (3) can adjust the output waveform frequency.

这是单机测试串口发送和接收数据的程序,很简单啊!完成基本的串口工作-This is the single test of transmitting and receiving serial data procedure is very simple ah! Completed the basic work of the serial
