Hello again.I found that i can adjust the pwm duty cycle from 40% to 80% If i choose 30% i get a dc level signal.If i set for 20% duty cycle i get 80%.What seems to be the problem.Do i have an overfl ...

First of all thank you Ttelmah for your help.I tested it and i got a 50% duty cycle.So i will have to make a matrix that will contain the appropriate values so i can get the duty cycle range that i wa ...

OK. I want to have 1 KHz Pwm frequency and to be able to change the duty cycle, by loading the appropriate value to the CCPR1L:CCP1CON<5:4 registers, from 20% to 100% . So with the 3276800 Hz cryst ...

Hello. I am working on a project with a PIC 18F2520 chip. I am using its PWM. I have an external crystal of 3276800 Hz. I am having trouble to achieve the desired PWM freq. If I choose PR2 with 255 v ...

thank you bkamen for the help. I think i will go to the 18fxx option .

I read some datasheets already but it is too much data.Gues i will have to choose the best of them.I agree this is a CCS forum sorry.Ok then as for the PIC part of my project is it possible to use the ...

Hello. I am new to gsm modules. I wanted to ask some general questions:

1)I want to control a Gsm module (Samed Hilo NC) from my PC through RS232 adapter but in the same I want to be able to send A ...

Ok sorry. I guess I have to read more carefully. 1k-Bit and not 1 Kbyte as I thought. Embarassed

Ok lets say I want to write some bytes in the address 700. How can I do that if the write_byte command takes an input address with range 0-127 ?

Ok then. But how can I load the page I like before I set the address?

I don't want to open a new thread so I am writing my question here. First of all I can't get any access to the full datasheet of DS2432, I believe that in there I can solve many of my wonderings. Maxi ...

Thank you FvM for solving my confusion about this matter. It's always good to learn new things.

PCM Programmer the problem was the #use fast_io directives. I let the set_tris directives and the PORTx=0; instructions and it works. I also changed back the output_float(TOUCH_PIN) instruction in the ...

Ok I have put the init_ds2432 as the first instruction in main. When the while loop executes for the first time the touch_present function gives a TRUE result but when it executes again it gives FALSE ...

I use the touch_present function for a simple debug. Here is the code:

#include "C:\SotirasLcd\18F2520.h"
//INTRC_IO
#fuses INTRC_IO ,PROTECT,NOLVP,PUT,NOPBADEN,NOBROWNOUT,MCLR//B ...
