是否需要PIC32 UART溢出错误（OERR）解决方案？

您好朋友，我有一个PIC32 MX795F512L与UART配置通过使用FTDI到PC应用的通信。在我的配置中，我有一个设定的BUAD率100000 BPS的硬件和软件。下面是我在CODRESIGETETABDATUFFER（）上面的代码，在主循环中接收到特定的命令和处理。在上面的配置中，我已经完全发送和接收命令。但是实际问题是假设我已经通过PC命令发送，如{7q05}，{7p5000 }，{7Z05}，{7e5}}，{3uM+}，{3xM+}，{3ZM，{3ZM。+}…同时也接收相同的命令，但是每当UART ORR错误设置时，我错过了上述包{7q05}、{7p5000 }、{7Z05}、{7e05}、{3uM+}、{3xM+}、{3ZM+}中的一个。当Uart Oerr只检测时间的时候，但是当UART ORR没有检测到时，我已经完全收到了所有命令。那么，任何解决UART ORR设置的解决方案，我也必须阅读我的整个缓冲区吗？

    Hello Friends,

   I have a PIC32MX795F512L configure with UART via comunication using FTDI to PC Application.
In My configuration I have a set Buad Rate 1000000bps both hardware and software. Below is My code
#define SYS_FREQ (80000000L)
#define DESIRED_BAUDRATE (1000000) //The desired BaudRate

void TimerandUartInit(void)
{
int pbClk;

    pbClk = SYSTEMConfig(SYS_FREQ, SYS_CFG_WAIT_STATES | SYS_CFG_PCACHE);

OpenUART2(UART_EN |UART_NO_PAR_8BIT | UART_2STOPBITS , // Module is ON
    UART_RX_ENABLE | UART_TX_ENABLE | UART_RX_OVERRUN_CLEAR, // Enable TX & RX
    pbClk/16/DESIRED_BAUDRATE-1); // 1000000 bps, 8-N-1
    UARTSetFifoMode(UART3A, UART_INTERRUPT_ON_TX_NOT_FULL | UART_INTERRUPT_ON_RX_NOT_EMPTY);
    ConfigIntUART2(UART_RX_INT_EN | UART_TX_INT_DIS | UART_ERR_INT_EN | UART_INT_PR1 );
}


CHAR dummy;
void __ISR(_UART_2_VECTOR, ipl1) IntUart2Handler(void)
{
if(IFS1bits.U3ARXIF)
{
        if(U3ASTAbits.OERR != 0)
        {
         SerialGetDataBuffer();
            U3ASTAbits.OERR = 0;
            IEC1bits.U3ARXIE = 0;
            IEC1bits.U3ARXIE = 1;
        }
        else
        {
            if ((U3ASTAbits.FERR != 0) || (U3ASTAbits.PERR != 0))
            {
                dummy = U3ARXREG;
                U3ASTAbits.FERR = 0;
                U3ASTAbits.PERR = 0;
            }
            else
            {
                SerialGetDataBuffer();
            }
        }
        //while (U3ASTAbits.URXDA != 0);
        IFS1bits.U3ARXIF = 0;
}
if(IFS1bits.U3ATXIF)
{
  IFS1bits.U3ATXIF = 0;
}
if(IFS1bits.U3AEIF)
{
  IFS1bits.U3AEIF = 0;
}
} // Uart Handler


in above code SerialGetDataBuffer()  received particular command and processing in main Loop.
in above configuration i have completely send and receive command .

But actual Problem is Suppose i have send through PC command like {7Q50000} ,{7P50000}, {7Z50000},{7E50000}, {3UM+},{3XM+},{3ZM+} ...  And also receive same command but whenever UART OERR error set that time i have miss the one of the above packet   {7Q50000} ,{7P50000}, {7Z50000},{7E50000}, {3UM+},{3XM+},{3ZM+} THIS highlighted command is missing. when Uart Oerr Detect that time only .
but when is UART OERR not detect that time i have received completely all command.

So is that any solution to overcome UART OERR set that time also i have to read my whole buffer?
