Saludos amigos, mi pregunta va directo al grano, cual es el comando en mickro C, para enviar un mensaje cuando este este listo, me explico teno un programa que con 2 lcd estas envie y reciven datos siul=taneamente, pero quiero que solo envie cuando le de al enter me explico, ? adjunto dejo el programa..... ...
Código:
unsigned short rec,kp, cnt, oldstate = 0;
char txt[6];
// Keypad module connections
char keypadPort at PORTD;
// End Keypad module connections
// LCD module connections
sbit LCD_RS at RB4_bit;
sbit LCD_EN at RB5_bit;
sbit LCD_D4 at RB0_bit;
sbit LCD_D5 at RB1_bit;
sbit LCD_D6 at RB2_bit;
sbit LCD_D7 at RB3_bit;
sbit LCD_RS_Direction at TRISB4_bit;
sbit LCD_EN_Direction at TRISB5_bit;
sbit LCD_D4_Direction at TRISB0_bit;
sbit LCD_D5_Direction at TRISB1_bit;
sbit LCD_D6_Direction at TRISB2_bit;
sbit LCD_D7_Direction at TRISB3_bit;
