ASR M08-B设置软件 V3.2 arduino 2560+ASRM08-B测试程序 arduino UNO+ASRM08-B测试程序语音控制台灯电路图及C51源码(不带校验码) 继电器模块设置。 ASR M08-B是一款语音识别模块。首先对模块添加一些关键字,对着该模块说出关键字,串口会返回三位的数,如果是返回特定的三位数字,还会引起ASR M08-B的相关引脚电平的变化。【测试】①打开“ASR M08-B设置软件 V3.2.exe”。②选择“串口号”、“打开串口”、点选“十六进制显示”。③将USB转串口模块连接到语音识别模块上。接线方法如下:语音模块TXD --> USB模块RXD语音模块RXD --> USB模块TXD语音模块GND --> USB模块GND语音模块3V3 --> USB模块3V3(此端为3.3V电源供电端。)④将模块的开关拨到“A”端,最好再按一次上面的大按钮(按一次即可,为了确保模块工作在正确的模式)。⑤对着模块说“开灯”、“关灯”模块会返回“0B”、“0A”,表示正常(注意:0B对应返回值010,0B对应返回值010,返回是16进制显示的嘛,设置的时候是10进制设置的)。

mp3设计程序资料,采用c语言编写。 README file for yampp-3 source code 2001-05-27 This is the current state of the yampp-3 source code, 2001-05-27. This code is intended to run on Rev. B of the yampp-3 PCB, but can ofcourse be used on compatible systems as well. It still uses the "old" song selection system as the yampp-2. However, the disk handling routines has improved a lot and the obviosly, the new VS1001 handling has been put in. The codesize is almost at it s maximum at 1F40 bytes. A .ROM file is included if you don t have the compiler set up. For now, the documentation is in the code

【下载说明】这里提供的是《》一书的CHm格式电子书下载。【内容简介】Ruby has been readily adopted by programmers in Japan and has had much documentation written for it in Japanese. As programmers outside of Japan learn about the benefits of Ruby, there is a growing need for documentation in English. The first book I wrote for O Reilly, Ruby Pocket Reference, was in Japanese. Since then Ruby has changed significantly. To meet the needs of non-Japanese programmers, we translated, updated, and expanded Ruby Pocket Reference into Ruby in a Nutshell.
