Could also just use some of the RN modules (I think the RN-131 comes to mind) from Microchip.
has Analog and GPIO -- all over WiFi (or Bluetooth and I think Xigbee) if you wanted.

Yeesh, I just looked up those rn-131 chips from Digikey.ca....about $50 ! and of course you need some 'other stuff' to make them work...my simple, easy solution is to use HC-12 modules for $6 each, as I pointed out 2 pages ago...once the 'RS232 code is running (PIC to PIC), simply add the HC-12s and the project is finished.

Good night ...
I'll use the HC12 module
But the question is and how can I improve this code to make it work with RS 232 communication? Is open for suggestions.
| Code: | #include<16f628a.h>
#FUSES NOWDT //No Watch Dog Timer
#FUSES INTRC_IO //Clock <=4Mhz
#FUSES PUT //Power Up Timer
#FUSES NOPROTECT //Code not protected from reading
#FUSES NOBROWNOUT //No brownout reset
#FUSES NOLVP //No low voltage prgming, B3(PIC16) or B5(PIC18) used for I/O
#FUSES NOCPD //No EE protection
#use delay(clock=4000000) // clock internal
#use rs232(baud=9600, xmit=PIN_B2,rcv=PIN_B1)
#define RF_OUTPUT PIN_B1 // O receptor RF é conectado
#define RF_INPUT PIN_B2 // O Transmissor RF é conectado
#define botao_incremento PIN_B0
#define botao_decremento PIN_B4
#define botao_start PIN_A3
#define led_ligado PIN_A2
int cont,ligado,tempo;
void main()
{
setup_ccp1(CCP_OFF);
setup_timer_2(T2_DIV_BY_4,249,1);
setup_vref(FALSE);
ligado=0;
cont=0;
tempo=10;
while (true)
{
// botão start
if ((input(botao_start)) && (ligado==0))
{
output_high(led_ligado);
ligado=1;
while (input(botao_start)){};
delay_ms(tempo);
}
if ((input(botao_start)) && (ligado==1))
{
output_low(led_ligado);
ligado=0;
cont=0;
while (input(botao_start)){};
delay_ms(tempo);
}
// botão incremento
if ((input(botao_incremento)) && (ligado==1))
{
if ((cont>=0) && (cont<=249))
{
cont++;
}
if (cont>=249)
{
cont=249;
}
delay_ms(tempo);
}
// botão decremento
if ((input(botao_decremento) && (ligado==1)))
{
if ((cont>=1) && (cont<=249))
{
cont--;
}
if (cont<=0)
{
cont=0;
}
delay_ms(tempo);
}
// Controle do PWM
if (ligado==1)
{
set_pwm1_duty(cont);
}
if (ligado==0)
{
set_pwm1_duty(0);
}
}
