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

本项目的目标设计微控制器操作的架子鼓和吉他，只包括鼓棍，脚踏板，并选取。这是通过执行连接到单片机的加速度计。由摇摆的棍子和在空气中挑选吉他你可以玩鼓和吉他演奏。我们还实施了回放功能你可以记录声音和稍后听听它。摇滚乐 ！

L298N是ST公司生产的一种高电压、大电流电机驱动芯片。该芯片采用15脚封装。主要特点是：工作电压高，最高工作电压可达46V；输出电流大，瞬间峰值电流可达3A，持续工作电流为2A；额定功率25W。内含两个H桥的高电压大电流全桥式驱动器，可以用来驱动直流电动机和步进电动机、继电器线圈等感性负载；采用标准逻辑电平信号控制；具有两个使能控制端，在不受输入信号影响的情况下允许或禁止器件工作有一个逻辑电源输入端，使内部逻辑电路部分在低电压下工作；可以外接检测电阻，将变化量反馈给控制电路。使用L298N芯片驱动电机，该芯片可以驱动一台两相步进电机或四相步进电机，也可以驱动两台直流电机。-L298N is produced by ST a high-voltage, high current motor driver chip. The chip uses 15-pin package. Main features are: high voltage, the maximum working voltage up to 46V output current, instantaneous peak current up to 3A, continuous operating current of 2A rated power of 25W. Contains two H-bridge high-voltage high-current full-bridge driver can be used to drive DC motors and stepper motors, relay coils and other inductive load using standard logic level signal control has two enable control terminal, input signal without affecting the case to permit or prohibit the device work a logic supply input, so that part of the internal logic circuits at low voltage work can be an external sense res

有了内核的代码，但是天哪，都太大了，有什么工具才可以迅速下载到目标板呢，tftp就有这个功能，运行在pc上！-with kernel code, but alas, too, what tools can quickly download it to the target board, tftp have this feature, running on the pc!
