How to configure the serial port

Selection of serial port number

Due to the design compatibility of software and hardware, the serial number of the software may be different from the serial number identification on the hardware. The specific correspondence is as follows:

• Z11 series platform

• Z6 series platform

• A33 series platform

Serial port baud rate configuration

1. Configure the baud rate when creating a new project

   

2. Project properties to modify the baud rate Right-click the project, select the Properties option in the pop-up box, and the following properties box will pop up

   

Serial port open and close

Open the source path jni/Main.cpp; we can see that the serial port is opened and closed when the program is initialized and destroyed.

void onEasyUIInit(EasyUIContext *pContext) {
    LOGD("onInit\n");
    // Open the serial port
    UARTCONTEXT->openUart(CONFIGMANAGER->getUartName().c_str(), CONFIGMANAGER->getUartBaudRate());
}

void onEasyUIDeinit(EasyUIContext *pContext) {
    LOGD("onDestroy\n");
    // Close the serial port
    UARTCONTEXT->closeUart();
}
