Hello,

I downloaded UART library where for UART send using function:

void Serial_write( uint8_t portNum, uint8_t send)
{
  if ( portNum == 0 )
  {

  /* THRE status, contain valid data */
  while ( !(UART0TxEmpty & 0x01) );
  LPC_UART0->THR = send;
  UART0TxEmpty = 0;/* not empty in the THR until it shifts out */


  }
....

I must send over UART
this array:

{0x55, 0x00, 0x07, 0x07, 0x01, 0x7A, 0xF6, 0x50, 0x00, 0x11, 0x30, 0x06, 0x30, 0x01, 0xFF, 0xFF, 0xFF, 0xFF, 0x2C, 0x00, 0x9C};

And I change function for send:

void Serial_wChar( uint8_t portNum, char send)
{
  if ( portNum == 0 )
  {

  /* THRE status, contain valid data */
  while ( !(UART0TxEmpty & 0x01) );
  LPC_UART0->THR = send;
  UART0TxEmpty = 0;/* not empty in the THR until it shifts out */

  }....

But when I monitoring data with FT232 on my terminal on computer I get failed data, I get something char.
Uart communication working, when I would like send string send normaly.
