Hi,
I'm new here and in C18... So, i was trying to do a clock, and here's my code:
How can I connect a keypad-phone to my code and print at the display the numbers that the user choose on the keypad? Assuming that my keypad is conected on PORTB. :|
Thanks for any help.
I'm new here and in C18... So, i was trying to do a clock, and here's my code:
Code:
#include "stdlib.h"
#include "p18f46k20.h"
#include "delays.h"
#include"stdio.h"
int x,z;
int unidadesegundo, dezenasegundo, unidademinuto, dezenaminuto, unidadehora, dezenahora;
Code:
unsigned int convert_7s(int num){
int vector[11] = {0b01000000, 0b11111001, 0b00100100, 0b00110000, 0b00011001, 0b00010010, 0b00000010, 0b11011000, 0b00000000, 0b00011000};
return vector[num];
}
Code:
unsigned int habilit_port(int display){
int vector[6] = {0b00100000, 0b00010000, 0b00001000, 0b00000100, 0b00000010, 0b00000001};
return vector[display];
}
Code:
void habilit_port_number(unsigned int port, int num){
switch(port){
case 1:{
PORTA = convert_7s(num);
break;
}
case 2:{
PORTB = convert_7s(num);
break;
}
case 3:{
PORTC = convert_7s(num);
break;
}
case 4:{
PORTD = convert_7s(num);
break;
}
}
}
void habilit_port_habilit(unsigned int port, int display_habilit){
switch(port){
case 1:{
PORTA = habilit_port(display_habilit);
break;
}
case 2:{
PORTB = habilit_port(display_habilit);
break;
}
case 3:{
PORTC = habilita_port(display_habilit);
break;
}
case 4:{
PORTD = habilita_port(display_habilit);
break;
}
}
}
Code:
void desabilit_port(unsigned int port){
switch(port){
case 1:{
PORTA = 0x00;
break;
}
case 2:{
PORTB = 0x00;
break;
}
case 3:{
PORTC = 0x00;
break;
}
case 4:{
PORTD = 0x00;
break;
}
}
}
Code:
void reset_numbers(int *num1, int *num2, int *num3, int *num4, int *num5, int *num6){
*num1=0;
*num2=0;
*num3=0;
*num4=0;

Code:

habilit_port_habilit(port2, 5);
if((*num5)==10){

}

desabilit_port(4);
}
}
Code:
void main(void){
TRISC= 0x00;
TRISD= 0b00000000;
PORTC=0xFF;
PORTD= 0b00000000;
reset_numbers(&unidadesegundo, &dezenasegundo, &unidademinuto, &dezenaminuto, &unidadehora, &dezenahora);
while(1){
int i;
for(i=0;i<40;i++){
write_display(&unidadesegundo, &dezenasegundo, &unidademinuto, &dezenaminuto, &unidadehora, &dezenahora, 3, 4);
desabilit_port(4);
if(i==39){
unidadesegundo++;
}
}
}
}How can I connect a keypad-phone to my code and print at the display the numbers that the user choose on the keypad? Assuming that my keypad is conected on PORTB. :|
Thanks for any help.
