ASR M08-B設(shè)置軟件 V3.2 arduino 2560+ASRM08-B測(cè)試程序 arduino UNO+ASRM08-B測(cè)試程序語(yǔ)音控制臺(tái)燈電路圖及C51源碼(不帶校驗(yàn)碼) 繼電器模塊設(shè)置。 ASR M08-B是一款語(yǔ)音識(shí)別模塊。首先對(duì)模塊添加一些關(guān)鍵字,對(duì)著該模塊說出關(guān)鍵字,串口會(huì)返回三位的數(shù),如果是返回特定的三位數(shù)字,還會(huì)引起ASR M08-B的相關(guān)引腳電平的變化。【測(cè)試】①打開“ASR M08-B設(shè)置軟件 V3.2.exe”。②選擇“串口號(hào)”、“打開串口”、點(diǎn)選“十六進(jìn)制顯示”。③將USB轉(zhuǎn)串口模塊連接到語(yǔ)音識(shí)別模塊上。接線方法如下:語(yǔ)音模塊TXD --> USB模塊RXD語(yǔ)音模塊RXD --> USB模塊TXD語(yǔ)音模塊GND --> USB模塊GND語(yǔ)音模塊3V3 --> USB模塊3V3(此端為3.3V電源供電端。)④將模塊的開關(guān)撥到“A”端,最好再按一次上面的大按鈕(按一次即可,為了確保模塊工作在正確的模式)。⑤對(duì)著模塊說“開燈”、“關(guān)燈”模塊會(huì)返回“0B”、“0A”,表示正常(注意:0B對(duì)應(yīng)返回值010,0B對(duì)應(yīng)返回值010,返回是16進(jìn)制顯示的嘛,設(shè)置的時(shí)候是10進(jìn)制設(shè)置的)。

neural network utility is a Neural Networks library for the C++ Programmer. It is entirely object oriented and focuses on reducing tedious and confusing problems of programming neural networks. By this I mean that network layers are easily defined. An entire multi-layer network can be created in a few lines, and trained with two functions. Layers can be connected to one another easily and painlessly.
