BAUD RATE CHANGE

I am using mkw01z128 boar. It has default baud rate on uart0,1,2 - 115200. But I need another baud rate. How to change it ?

Hello Odilbek

In App.c file you can find the App_init function (line 208) in which serial interface is initialized:

    /* Initialize the serial terminal interface so that we can print out status messages */
    Serial_InitInterface(&interfaceId, APP_SERIAL_INTERFACE_TYPE, APP_SERIAL_INTERFACE_INSTANCE);
    Serial_SetBaudRate(interfaceId, gUARTBaudRate115200_c);
    Serial_SetRxCallBack(interfaceId, UartRxCallBack, NULL);

Serial_SetBaudRate function does configure baud rate, if you want to change baud rate, you should replace gUARTBaudRate115200_c parameter by anyone of followings:

typedef enum{
    gUARTBaudRate1200_c   =   1200UL,
    gUARTBaudRate2400_c   =   2400UL,
    gUARTBaudRate4800_c   =   4800UL,
    gUARTBaudRate9600_c   =   9600UL,
    gUARTBaudRate19200_c  =  19200UL,
    gUARTBaudRate38400_c  =  38400UL,
    gUARTBaudRate57600_c  =  57600UL,
    gUARTBaudRate115200_c = 115200UL,
    gUARTBaudRate230400_c = 230400UL
}serialUartBaudRate_t;

Save changes and re-compile the project.

I hope this can help you!
