Hi everyone,
I am using a PIC16F628A, and a sparkfun serial LCD,,
Well, I have a problem in displaying. Sometimes, the LCD works well, others it prints some strange characters such as Omega Symbol ...

Thank you

Hello,
I am using a serial LCD as the following one :

#include <18f2455.h>

#FUSES HS,NOLVP,NOPROTECT,NOWDT,PUT
#USE DELAY(clock=16M)
#include "Flex_LCD216.c"

...

Hi,
I used PIC18F2455 Crystal is 16MHz,
I used an ultrasonic range finder such as this one :
https://www.sparkfun.com/products/9491
it's very obvious that I can use 3 ways to get the reading,

Question ::

When the x-axis in the sensor points to the North,
what should the output be ?
I Have changed the display type to be :

fprintf(COM_LCD,"%Lu, %Lu, %Lu ", compass.x ...

Thank you guys for your help.
I believe there was no mistake in my program.
I could find out that the mistake was Hardware mistake.
Thank you for your replies

I have written this program :

#include <18F2455.H>
#device PASS_STRINGS=IN_RAM
#FUSES NOWDT,HS,NOBROWNOUT,NOLVP
#USE delay(clock=16M)
int counter = 0 ;

#int_EXT

Ok,
As I have been reading about the interrupts. I found out the following.
First I have to write the function in which the interrupts should do.
In my situation I should write the following pro ...

Thank you for letting me notice about the pin
and Yes
I have checked the datasheet.
B0 refers to External Interrupt 0
B1 refers to External Interrupt 1
B2 refers to External Interrupt 2

how can I set interrupts at any port in the PIC ?
I need to set also a counter that counts up when the interrupt goes from h_to_low and then goes from low to high.

I started to call some interru ...

PCM programmer...
I got confused about how to calculate the Duty. I used the CCS help and figured out the following :
1- when writing setup_ccp1(CCP_PWM)
Time = (1/clock) * 4 * 16 * (period+1)
In ...

Ok thanks, but I have another question. How can I turn the PWM off and use the port as Digital output ???

Thank You so Much.
^_^
just as I wanted.

Ok, Thank you .

I also want to be sure that I used the right pins. and if it helps. I'm using DC motors
PIC 18F2455
C2 for PWM1
C1 For PWM2
....
trying now

Ok,
here is what you should do.
