Problem with the uart PIC 24FJ128GA006
PostPosted: Fri May 28, 2010 10:16 pm     Reply with quote
Hello I use the uart in the PIC24FJ128GA006, but I have this problem:
Quote:

"Undefined identifier PIC_C1"
"Undefined identifier PIC_C2"

This is part of my code:
Code:

.....
#use rs232(UART1,baud=9600,parity=N,bits=8)
...
#define CTS PIN_C1 //Clear to send
#define RTS PIN_C2 //Request to send
.....
// ********** INICIALIZA HOST USB ***************************
void inic_host()  {

   output_high(RTS);
   while(input(CTS));     //espero que el VDRIVE2 busque el pic
   output_low(RTS);       //le envio una respuesta
   
  serial_sendbyte('S'); //envía un SCS (habilitar comandos en modo corto)
   serial_sendbyte('C');
   serial_sendbyte('S');
   serial_sendbyte(0x0D);  //caracter para indicar fin del comando(enter)

}
//**************************************************

//***ENVIA UN CARACTER AL PUERTO SERIE ***********************

void serial_sendbyte(unsigned int8 TXbyte){ //ENVIAR UN CARACTER
   
      while(input(CTS));
      putc(TXbyte);
     
}

I have PCD 4.104. Can anyone help me?

The said chip has no C1 or C2 pin. They are only present with larger package types. Check the datasheet or CCS device file.

Thanks I saw my error, after I posted the problem.
I have other question: I need to especify the RX and TX pins?

PIC24FJ128GA006 has fixed UART pins. Specifying UART1 or UART2 in the #use rs232 statement is sufficient.
