Hi everybody !

I'm new in dsPIC, I wrote a program, very simple, this is my code :

#include <30F2020.h>
#device *=16
#FUSES NOPROTECT, NOWDT, FRC
#use fast_io(d)

void main ...

I solved this problem.

The problem is timer 0 overflow too fast, so encoder pulse can't increase. After that, I increase prescaler of timer 0 to 256 and it worked ok.

Hi everybody !

I want to control a DC motor. I use PWM module and timer 0 and timer 1 :

+ Timer 0 : Used to calculate timer.
+ Timer 1 : Used to read pulse from encoder to calculate speed of m ...

Many thanks bkamen !

I didn't know the statement "#pin_select", I'be tried it, it's ok.

Your nick name seem you're in Viet Nam, I learning in HUT, nice to meet u ;)

Hi everybody !

I use dpPIC33FJ12MC202 to control DC motor, I want to use QEI module of this MCU, but in CCS, I can't find which function can define pins for QEI module. The function available is : ...

Looking at the PCB though. What is the component left of the PIC, with just four pins?.
Assuming this part isn't doing anything silly, then it looks 'possible'. I'd say the most likely proiblems were ...

Hi everybody !

I have a pickit, and I've tested RS232 module on that, it's ok, but when I design my printed circuit, it doesn't work. I tried it 3 times Mad

I use max232 (product of maxim) a ...

Hi everybody !

I want to use capture module in PIC16F887, this is my simple code :

#include <16f887.h>
#use delay(clock = 4000000)
#fuses LP,XT,EC_IO,INTRC,NOWDT,WDT,NOPUT,PUT
# ...

I've already tested it in real circuit, It works well, no matter, the problem is simulator software !!!

Thanks for reply !

Hi everybody !

I want to test PWM on CCP1 pin of PIC16F887A, this is my code :

#include <16F887.h>
#device *=16,ADC = 8
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay ...
