Remove debounce on IR Sensor

[zr125]

How do i remove debounce? it is not a swtich debounce. my source code are as follow.

unsigned int IR1,IR2;

void main(){

TRISA = 0xFF;
ADCON1 = 0x00;
TRISD = 0x00;
UART1_Init(9600); // Initialize UART module at 9600 bps
delay_ms(100); // Wait for UART module to stabilize

for(;{
IR1 = Adc_Read(1);
IR2 = Adc_Read(2);

if (IR1<930){
PORTD.F2 = 1;
delay_ms(200);
UART1_Write_Text("a");}

else if (IR2<930){
PORTD.F1 = 1;
delay_ms(200);
UART1_Write_Text("b");}

else {
PORTD = 0x00;
delay_ms(200);}}}

its about ir sensor, when then sensor is trigger, it sends data thru uart. it supposed to be in sequence, either IR1-->IR2 or IR2-->IR1.

my problem is when sensor trigger, it send bounce data like i want it to send "a" then "b" but instead, it send double or triple "a" then "b". how do i set it to send "a" once only, then "b" and vice versa.

Either your ir sensor is keeping output the same value than u expected or ur adc buffer keeps the same value when u come to the loop again. have more delay or limiit ir sensing output or clear the adc buffer....
