I purchased an LPC2106 board from olimex with a 14.7456 MHz crystal.
I'm having a very difficult time getting the serial port to work and output to the screen.
I'm trying to transmit at 57600,8,1,n.
The mcu osc is set up for 4 times the crystal.
I programmed the board with a precompiled uart program that echos characters back, and it worked fine, so the connections are good and the uc works.
 
Here is the code:
 
#include <C:\GNUARM\bin\lpc210x.h>
 
int main(void);
void Init(void);
void Delay (unsigned long a); 
 
int main(void)
{
 Init();     //Initialize clock
  IODIR=0x000000080;           //P0.7 is output(LED)
     
  //Setup UART
  PCONP &= 0x08;
  UART0_IER = 0x00;
  UART0_LCR = 0x80;
  UART0_DLL = 0x20;
  UART0_DLM = 0x00;
  UART0_LCR = 0x03;
  UART0_FCR = 0x07;
 while (1) 
    {
  // flash LED
   IOCLR |= 0x00000080;                    //LED on
      Delay(100000);
      IOSET |= 0x00000080;                     //LED off
      Delay(100000);           
   
  // Transmit Hi
  while((UART0_LSR & 0x40) == 0){}
   UART0_THR = 'H';
  while((UART0_LSR & 0x40) == 0){}
   UART0_THR = 'i';
 } 
}

void Init(void)
{
 // Init PLL
    PLLCFG=0x23;                 // P=2, M=4, PLLfreq = 235,9296 Mhz, CCLK = 58,9824 Mhz
    PLLFEED=0xAA;     // 14.7456MHz
 PLLFEED=0x55;   
    PLLCON=0x01;                 // Enable the PLL
    PLLFEED=0xAA;
 PLLFEED=0x55;
    while(!(PLLSTAT & 0x0400)){}  // Wait for PLL to lock
    PLLCON=0x03;                 // Connect PLL as clock source
    PLLFEED=0xAA;
 PLLFEED=0x55;   
    //Init MAM & Flash memory fetch
 MAMTIM=0x07;
 MAMCR=0x00;
 MAMMAP=0x01;
    VPBDIV=0x01;                 //pclk = cclk
}
void Delay (unsigned long a)
{
    while (--a!=0){}
}
 
 
The code flashes the LED but "Hi" is not sent???
Any help would be greatly appreciated.

It doesn't look like you've set up the UART pins (PINSEL0)

Okay it works now.  Thank you.
