Request PICMICRO codes here (C Only)

Pa edit naman po ako ng C code ko para sa sumobot ko kasi yung pins r0-r3 ndi nya narearead as input .. output sya kc nakakabit yung proximity ko dun tapos yung indicator na led naka on kahit walang object tapos di nya din finefetch yung input ng sensor port b lang po gamit ko yung prox ko nasa rb2 po tapos ung rb1 at rb3 ay line sensor .. pag naka onn po xa forward lang sya pahelp po thanks!

#include <pic.h>
//configuration fuses
__CONFIG(XT & WDTDIS & PWRTDIS & UNPROTECT);
void delay(void) //this is a delay function
{
unsigned int i;
for(i=0;i<0xFFFF;i++) //FOR loop does nothing, just
; //increment variable i from 0
} //to 65535
void main ()
{
TRISB = 0b00001111; //RB7-4 are output pins
if (TRISB2 = 0)
{
PORTB = 0b10100000; //forward
}
else

while(1) //infinite loop

delay(); //invoke delay() function
}

heto ang gamit ko, macro tsaka bit operators and shifts

//PWM output pin
TRISC2 = 0;

//disable interrupts
PEIE = 0;
GIE = 0;

//enable PWM
TMR2ON = 1;
}



tanong ko lang po, pano gamitin yong pwm.h at pwm.c?
kasi po may gagawin kami na project may part na kelangan icontrol ung RPM ng motor..
diba ichange lang ang duty cycle nyan? pano ko po gagamitin ung pwm.h at .c para magawa yon? TIA

mga master, hindi ko tlga makuha sa PIC to PIC Tx to Rx, transfer po sana ako ng 1word character.. baka meron po kayo smple program in mikroC po baka pwd po makahingi, kahit ung pinaka simple lang po, basta matransmit niya ung word then e display ng receiver PIC sa LCD, nahihirapan po ako mag program ng uart, paki check na lang po if may mali sa mga connections ko po.. tnx po tlg, ..

eto po ung image

TX

   unsigned char _data = 0x41;
   unsigned char _data1 = 0x42;
   unsigned char _data2 = 0x43;
   unsigned char _data3 = 0x44;
void main(){
  UART1_Init(9600);               // Initialize UART module at 9600 bps
  delay_ms (2000);
 
  do {
  UART1_Write(_data);
  delay_ms(1000);
  UART1_Write(_data1);
  delay_ms(1000);
  UART1_Write(_data2);
  delay_ms(1000);
  UART1_Write(_data3);
  delay_ms(1000);
  } while (1);
}

I know matagal na ito, pinag practisan lang..
Very basic po ito using mikroC.
