ASR M08-B設置軟件 V3.2 arduino 2560+ASRM08-B測試程序 arduino UNO+ASRM08-B測試程序語音控制臺燈電路圖及C51源碼(不帶校驗碼) 繼電器模塊設置。 ASR M08-B是一款語音識別模塊。首先對模塊添加一些關鍵字，對著該模塊說出關鍵字，串口會返回三位的數，如果是返回特定的三位數字，還會引起ASR M08-B的相關引腳電平的變化。【測試】①打開“ASR M08-B設置軟件 V3.2.exe”。②選擇“串口號”、“打開串口”、點選“十六進制顯示”。③將USB轉串口模塊連接到語音識別模塊上。接線方法如下：語音模塊TXD --> USB模塊RXD語音模塊RXD --> USB模塊TXD語音模塊GND --> USB模塊GND語音模塊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對著模塊說“開燈”、“關燈”模塊會返回“0B”、“0A”，表示正常(注意：0B對應返回值010，0B對應返回值010，返回是16進制顯示的嘛，設置的時候是10進制設置的)。

The PCA9549 provides eight bits of high speed TTL-compatible bus switching controlledby the I2C-bus. The low ON-state resistance of the switch allows connections to be madewith minimal propagation delay. Any individual A to B channel or combination of channelscan be selected via the I2C-bus, determined by the contents of the programmable Controlregister. When the I2C-bus bit is HIGH (logic 1), the switch is on and data can flow fromPort A to Port B, or vice versa. When the I2C-bus bit is LOW (logic 0), the switch is open,creating a high-impedance state between the two ports, which stops the data flow.An active LOW reset input (RESET) allows the PCA9549 to recover from a situationwhere the I2C-bus is stuck in a LOW state. Pulling the RESET pin LOW resets the I2C-busstate machine and causes all the bits to be open, as does the internal power-on resetfunction.

Atheros無線芯片AR-6000系列wince 6驅動源代碼(這東西我也沒用過別問我,我是搜別的wince資源搜到的) AR6K SDIO support. Requires firmware 1.1 on SD13 cards. readme: Atheros Communications AR6001 WLAN Driver for SDIO installation Read Me March 26,2007 (based on k14 fw1.1) Windows CE Embedded CE 6.0 driver installation. 1. Unzip the installation file onto your system (called installation directory below) 2. Create an OS design or open an existing OS design in Platform Builder 6.0. a. The OS must support the SD bus driver and have an SD Host Controller driver (add these from Catalog Items). b. Run image size should be set to allow greater than 32MB. 3. a. From the Project menu select Add Existing Subproject... b. select AR6K_DRV.pbxml c. select open This should create a subproject within your OS Design project for the AR6K_DRV driver. 4. Build the solution. 轉自Tony嵌入式,原文地址：http://www.cevx.com/bbs/dispbbs.asp?boardID=4&ID=11762&page=1
