A led flashing every half a second, while the other will only be accessed when I send a low level signal to RB0 in the microcontroller, I wanted to know if something is missing, since I did exactly as they asked me and even then, only the polling led is blinking, the interrupt does not occur: here is the code in C:
bit controle;
void interrupt()
{
if(INT0IF_bit)
{
controle = ~controle;
INT0IF_bit = 0;
if(controle) RA0_bit = 1;
else RA0_bit = 0;
}
}
void main()
{
TRISA = 0xFC;
TRISB = 0xFF;
PORTA = 0xFC;
PORTB = 0xFF;
IPEN_bit = 1;
RBIP_bit = 1;
INTCON = 0x90;
INTCON2 = 0x00;
controle = 0;
while(1)
{
// Lógica para fazer LEd piscar por Polling..
RA1_bit = 0x01;
delay_ms(TempoPolling);
RA1_bit = 0x00;
delay_ms(TempoPolling);
// Fim da Lógica
}
