[En-Nut-Discussion] HOW TO USE SPI UART FUNCTIONS

[zzzdh]

I am a Nut/OS beginner, could you give me some examples about how to use SPI UART functions below:
    UartSpiInput (NUTDEVICE *dev) 
     UartSpiOutput (NUTDEVICE *dev) 
     UartSpiFlush (NUTDEVICE *dev) 
    UartSpiIOCtl (NUTDEVICE *dev, int req, void *conf) 
     UartSpiInit (NUTDEVICE *dev)
