PostForum: General CCS C Discussion   Posted: Thu Dec 25, 2014 11:06 pm   Subject: @PCM programmer
My PIC external Crystal frequency is 20Mhz and I am using PIC18F2550. Since I was not sure whether PIC could be used for such a high non-standard baud rate so, I have used Freescale Microcontroller fo ...

I think,I have mentioned in summary of my findings regarding PWM and Timer2 settings that

PR2=Period=Middle Value = 79

Ok let me revisit the links provided by PCM Prgrammer.

Actually,I need ...

PCM programmer thank you for your reply. I have been able to deduce following the formulas from the post whose link you have shared :

1. PWM Period = 1/(Clock Frequency)*4*t2div*(Period+1)

Ttelmah,the code that you have posted does not work either as it gives error for "NOPDADEN "

The actually working code that I have tried is given below

Here is the simple code for character loop back in CCS for PIC Compiler Version 5.015:



// character loop back test

#if defined(__PCM__)
#include <18F2550.h>
#fuses NOWDT,INTX ...

I am using CCS C Compiler version 5.015

I have tried following configurations and fuses settings for oscillator:

#fuses NOWDT
#use delay(internal=8MHz)

but these settings didn't work

I ha ...

Hi,

I am new to CCS Compiler, previously I used to use mikroC for PIC.

I want to operate my PIC18F2550 at 8MHz with internal oscillator.
what fuses and configuration bits I need to set for this ...
