Hello,
Newly I just trying to make something with PIC.
I have some newbie question, I hope I can get the solution from you all. 
Do anybody here know how to upload code (like in the Arduino) to PIC18F452?
I only have PIC2 Programmer and both MPLAB and PicKit2 software in PC, can I upload the code to the PIC18F452 only in breadboard?
Or do I need other tools?
Thank you.
That`s all I use for my projects most of the time too 
although I Do use GCBasic for almost all of my PIC programming.
in MPlab, assuming you have a program to upload, you simply go into Configure and pick from the list what Chip you are using, then you choose what programmer you`re using in "select programmer".
click on Quick Build, then click Program.
a few seconds later if all goes well it`ll be programmed!
this is an example I did here: http://www.element14.com/community/people/YT2095/blog/2012/04/13/surprisingly-simple-pic-development
Thank you, now I can make a led blink at least 
But I actually want to use a servo, so I uploaded the source code successfully but there is no response from the connecting servo.
I connect to servo to RD0 and RD1
Here is a bit of my code that I suspected contain the errors.
void main(void)
{
//Set I/O ports
TRISD = 0x00;
//Clear Output Ports
PORTD = 0x00;
void InterruptHandlerHigh() // Declaration of InterruptHandler
{ //This gets run when either timer overflows from FFFF->0000
if(INTCONbits.TMR0IF) //check if TMR0 interrupt flag is set
{
WriteTimer0( 0x3CAF ); //Reset Timer0 for 20mS Delay
WriteTimer1( 0xFC77 ); //Reset Timer1 for 1mS Delay
count = 0; //Reset Timer1 Interrupt Counter
INTCONbits.TMR0IF = 0; //Clear TMR0 Flag
}
if(PIR1bits.TMR1IF == 1 && PIE1bits.TMR1IE == 1)
{ //If Timer1 interrupts, do your thing...
count++; //Increment Timer1 Interrupt Counter
switch(count){ //Choose which servo to modify:
case 1: PORTD = 0x01;
WriteTimer1( servo0 ); //Right Eyebrow
break;
case 2: PORTD = 0x02;
WriteTimer1( servo1 ); //Left Eyebrow
break;
case 3: PORTD = 0x00;
WriteTimer1( 0 );
break;
}
And here is the whole code.
