PIC Teclado Matriz

[Lucas Pereira de Souza]

Opa pessoal, recentemente estou trabalhando e um projetinho, para isso eu desenvolvi uma biblioteca para um teclado 4x4, o funcionamento do mesmo para um digito funciona que e uma beleza, entre tanto, eu nao consegui elaborar um código que eu aplique mais de um digito como por exemplo o valor 563. Se alguém puder ajudar ficaria grato xD.

Segue o código abaixo.

Não analisei o programa mas a opção de mostrar 456 no display é algo como a cada pressionada desloque a posição de impressão no display. Algo como (chute)
 

//...
unsigned char i=1;
//...
Lcd_Out(2,i++,txt2);//ESCREVE NO LCD SEGUNDA LINHA

Consulte o help da sua função lcd_out pra ver a função dos argumentos

Muito obrigado ajudou muito, achei duas soluções para o problema, a primeira foi da maneira que você falou, vai atribuindo valores e pula para segunda coluna, sendo assim depois desse processo basta ler o LCD através do microcontrolador, habilitando o modo leitura do LCD. O segundo método, nao precisa ter um LCD para atribuir os dígitos sequencialmente, basta  usar um laço while e atribuir cada digito em uma posição do vetor e depois juntar ambas partes veja:

 

while(RE1_bit == 0)
     {
     char txt1[] = "PRIMEIRO DIGITO";
     Lcd_Out(1,1,txt1);//ESCREVE NO LCD PRIMEIRA LINHA
     teclado();
     soma[0] = digito*10;
     }
     
     delay_ms(500);
     Lcd_Cmd(_LCD_CLEAR);// Clear display
     delay_ms(500);
     
     while(RE1_bit == 0)
     {
     char txt1[] = "SEGUNDO DIGITO";
     Lcd_Out(1,1,txt1);//ESCREVE NO LCD PRIMEIRA LINHA
     teclado();
     soma[1] = digito;
     }
     delay_ms(500);
     valor = soma[0] + soma[1];
     delay_ms(500);

     }
