Hello,

this code is from other compiler, i want to change it to use ccs.
In pic18f26j50.
which is the equivalent to this line?
Code:
while(TXSTA.TRMT);    //wait to send data


Code:

void USART_putsRN(char * data)
{
    char  c;
   
    if(data == NULL)
        return;

    do
    {
        putc( *data );
        while(TXSTA.TRMT); //   espera a enviar el dato
        delay_ms(10);
        data++;
    }while( *data != 0);


    return;
}

Just use puts.

Already there as a function. Sends a 'string', waiting for each character to send, and stopping when it reaches the 'null' terminator.

Exactly replaces the whole function, except for the 10mSec delays.

If you need to duplicate it:

Code:

TRMT=getenv("BIT:TRMT")

//then wait with

    while(TRMT)
       ; //   wait for transmitter buffer empty bit
