利用藍牙低能量無線控制機器人小車

　　最新的藍牙4.2低能量（竹葉提?。?，也被稱為藍牙智能，是為物聯(lián)網(wǎng)（物聯(lián)網(wǎng)）。原生支持藍牙技術(shù)在每一個主要的操作系統(tǒng)，使移動應(yīng)用程序開發(fā)方便。

　　利用PSoC Creator 3.2，Xcode 6和快速應(yīng)用程序開發(fā)環(huán)境，應(yīng)用程序可以用來處理一個簡單的遠程控制汽車使用iPhone，演示了關(guān)貿(mào)總協(xié)定的概況和間隙外設(shè)嵌入式BLE系統(tǒng)開發(fā)使用。汽車是由兩臺電動機和正交編碼器和Cypress半導(dǎo)體psoc4200 BLE設(shè)備H橋

　　The project starts with a simple LED and touch pad control that indicates the state of the connection. The initial CAPSense slider is used to control a red LED， with a blue LED for when the board is not connected.

　　Creating a new project for the PSoC4100 BLE， the components can be added to a simple schematic. The BLE component is added to the graphics design tool and linked to the CapSense component. A PWM is needed to drive the LEDs and because the blue LED is active low the PWM needs to be inverted， so a NOT gate is used from the library.
