fm, 串口, TE, AC, TI

今天捣鼓了一下串口。
代码：
//-----------------------------------------------------------------------------
// Includes
//-----------------------------------------------------------------------------
#include <SI_EFM8BB1_Register_Enums.h>
#include "retargetserial.h"
#include "InitDevice.h"

//-----------------------------------------------------------------------------
// SiLabs_Startup() Routine
// ----------------------------------------------------------------------------
// This function is called immediately after reset, before the initialization
// code is run in SILABS_STARTUP.A51 (which runs before main() ). This is a
// useful place to disable the watchdog timer, which is enable by default
// and may trigger before main() in some instances.
//-----------------------------------------------------------------------------
void SiLabs_Startup (void)
{
  // Disable the watchdog here
}

//-----------------------------------------------------------------------------
// Main Routine
//-----------------------------------------------------------------------------
void main (void)
{
unsigned char inputcharacter;    // Used to store character from UART

enter_DefaultMode_from_RESET();
SCON0_TI = 1;                      // This STDIO library requires TI to
                                    // be set for prints to occur
while (1)
{
   RETARGET_PRINTF ("\nEnter character: ");
   inputcharacter = getchar();
   RETARGET_PRINTF ("\nCharacter entered: %c", inputcharacter);
   RETARGET_PRINTF ("\n    Value in Hex: %bx", inputcharacter);
}
}
