did you pay for the compiler?
If you did, just download from mikroe.com website and reinstall everything.

I am using easypic5 board, 20mhz crystal and 18f2550. The lcd_init comand doesn't work, it says: 22 324 Undeclared identifier 'Lcd_Init' in expression 24 324 Undeclared identifier 'Lcd_Cmd' in expression Here's my code: sbit LCD_RS at RB4_bit; sbit LCD_EN at RB5_bit; sbit LCD_D4 at RB0_bit; sbit LCD...

thank you guys, it's certainly helpful.
I have something to work but still not sure about few things. Right now, I'll have to figure out how to get the correct time (multiplying prescaler with tmr etc etc).

I have a simple project using 18f4550. I am using a 16x2 lcd display and I want the display to change 5 minutes later after I pressed a button (doesn't matter what button). During that 5 minutes, I want to still be able to use my pic to do other things (turning on and off led for example) I know I n...

Thanks for the tutorial w7ami, I've been looking for this.
This thread should be moved to the FAQ.

just tested the interrupt part, no problem.

host88

darn it nobody helped :shock:

oh yea, I got it working
I haven't try the interrupt thing, but everything else is working great.

Too tired to write the step now, pm me for more info.
I'll do a write up soon.

no, it's full version.

Here's my code:
(blinking led on portD)

Code: Select all

void interrupt(){
  asm nop
}

void main_tread() {
PORTD = 0;
TRISD = 0;

while(1){
PORTD = ~PORTD;
delay_ms(1000);
}

}

void main () org 0x800 {

   main_tread();
}

I need to use usb bootloader by microchip for my pic 18f4550. I followed the direction here: http://www.mikroe.com/forum/viewtopic.php?t=7370 mlk file : //ROM MEMORY #pragma SetRomSize(32767) #pragma SetPage(PAGE0, 0x000808, 0x7FFF) #pragma SetPage(PAGE1, 0x000800, 0x830) Code: void interrupt(){ asm...

I solved the problem. I need to add INTCON2.RPBU = 0 //All PORTB pull-ups are disabled. I have no idea why I need that, but it works. :lol: Anyway, here's the final code. Somebody might need it. unsigned int flag_RB; void interrupt() { if (INTCON.RBIF == 1) { unsigned short x; x = PORTB; flag_RB = 1...

I changed the code a little bit unsigned int flag_RB; void interrupt() { if (INTCON.RBIF == 1) { unsigned short x; x = PORTB; flag_RB = 1; INTCON.RBIF = 0; } } void main() { TRISB = 0b11111111; CMCON = 7; TRISD = 0b00000000; PORTD = 0b00000000; PORTB=0; INTCON.RBIE = 1; // Port Change Interrupt Enab...

What pull up resistor should I use? 10k? 5k?
tie it to the ground or +5vcc?
