Hi
I am testing the UART1 on PIC24FJ128GA006
On the errata say's that 64 pin version don't have flow controll and I =

am try to get this with an extra PIN (LATF6)

I see that the data gets in but never gets sent out.

void UART1Init()
{
    // Set directions of UART IOs
    UART1_TX_TRIS =3D 0;  // INGRESSO =3D 1  - USCITA =3D 0
    UART1_RX_TRIS =3D 1;
   UART1_RTS_TRIS =3D 0;
   //UART1_CTS_TRIS =3D 1;
  =

    U1BRG =3D BAUDRATEREG1;      // Baud Rate
    U1MODE =3D 0;
    U1STA =3D 0;
   U1MODEbits.PDSEL0 =3D 0;     // 8-bit data c/ no parity
   U1MODEbits.PDSEL1 =3D 0;
   U1MODEbits.STSEL =3D 0;      // 1 bit di STOP

   U1MODEbits.RTSMD =3D 0;      // SIMPLEX MODE for RS485
   U1MODEbits.UEN0 =3D 0;       // ALL pins used
   U1MODEbits.UEN1 =3D 0;       // even U1RTS and U1CTS

   U1MODEbits.BRGH =3D 0;       // Baud rate generator (accertiamoci che =

sia a zero) =


#warning:  DEBUG ME DA CONTROLLARE IN SEGUITO U1STAbits.UTXISEL0 =3D 0;
    U1STAbits.UTXISEL0 =3D 0;    // when interrupt occurs
    U1STAbits.UTXISEL1 =3D 0;    // when interrupt occurs
// ******* DA CONTROLLARE IN SEGUITO =

++++++++++++++++++++++++++++++++++++++++++++++++++++

    U1STAbits.URXISEL1 =3D 0;    // E' arrivato qualcosa
    U1STAbits.URXISEL0 =3D 0;    // Non importa se URXISEL1 =E8 a zero

    U1MODEbits.UARTEN =3D 1;
    U1STAbits.UTXEN =3D 1;
   U1STAbits.UTXBRK =3D1;
   U1TXREG =3D 0x0000;
      // reset RX flag
     IFS0bits.U1RXIF =3D 0;
   // IEC0bits.U1RXIE =3D 1;       // recieve INTERRUPT service
   // IEC0bits.U1TXIE =3D 1;       // trasmit INTERRUPT service

}



void  UART1PutChar(char Ch){
    // wait for empty buffer =

      _LATF6 =3D1;
    while(U1STAbits.UTXBF =3D=3D 1);

      U1TXREG =3D Ch;

      _LATF6 =3D0;
}

If I but 2 breakpoints. One on the while function, and one on the _LATF6 =
=3D0;
then data gets out.
Using RF6 for 485 direction controll

Same programm works properly with flow control on PIC24F64GA002

Thank you
