UART help(LPC1114)

Anthony Serra

Is it possible for me to send a C file over a UART connection to an LPC1114 mcu? The C file has configurations for the mcu, if it is possible how can I do so using C# in Visual Studio.

    So heres the interrupt on the firmware side

    void UART_IRQHandler(void) {
        static NetworkLayerState networkState = Network_Idle;
        unsigned int interruptId = LPC_UART->IIR;

        while((interruptId & 1) == 0)
        {
                switch((interruptId >> 1) & 0x07)
                {
                        case 0x02: //Receive Data Available
                        case 0x06: //Character time-out indicator (buffer flush)
                                networkState = NetworkStateMachine(LPC_UART->RBR & 0xFF, networkState);
                                break;

                        case 0x03: //Receive Line Status interrupt
                                break; //Not handling frame errors
                }

                interruptId = LPC_UART->IIR;
        }
}

    And now I want to send for example

    WriteRegisterOpt(8, 1, 0x03249249, 0);


    WriteRegisterOpt is a function within the mcu that I have coded.

    I am still fairly new when it comes to how exactly the mcu and computer interact so I'm confused as to how I can take data I send and then code firmware to utilize it.
