CML公司语音压缩Codec CML7261 G.729A编码部分驱动代码cmx7261_G.729A

1、基于stm23f103c8t6的开发板开发，外接rc522读卡板。 2，实现让windows系统把设备认成hid键盘，当刷M1卡时，把4字节的卡号以键盘输入的形式上送到电脑。 3，已在xp，win7系统上测试。把鼠标放在文本输入框中，刷卡，卡号即可显示在文本框中，并回车换行。(1, based on the stm23f103c8t6 development board development, external rc522 read card board. 2, to achieve the windows system to recognize the device as HID keyboard, when you brush the M1 card, the 4 byte card number in the form of keyboard input to the computer. 3, has been tested on the XP, win7 system. Put the mouse in the text input box, swipe the card, the card number can be displayed in the text box, and enter the line feed.)

采用stm32内部TIM编程 实现对输入信号的计数测频 可测0HZ—65536HZ的频率(TIM programming using the internal stm32 Count the input signal to achieve frequency measurement Can be measured 0HZ-65536HZ frequency)
