[SOLVED] PIC16f1527 configuration bits doubt

[ragav4456]

How to 16f1527 configure bits?

__CONFIG(1, FOSC_HS & PWRTE_ON & BOREN_OFF & WDT_OFF & MCLRE_ON & CP_OFF & CLOCKOUT_ON & IESO_OFF & FCMEN_OFF);
__CONFIG(2, WRT_OFF & VCAPEN_OFF & LVP_OFF & LPBOR_OFF & BORV_OFF & STVR_ON);

Kindly help me

Simple LED On/Off program only?

Hi,

You need to say what oscillator your are using, its currently set for a high speed external crystal, is that what you want - more usual to use the internal oscillator.

Also it has Mclre configured as ON, so you must connect that pin to VDD via a 10k resistor or the program will not run.

Thr rest of the parameters should be ok.

To use the internal oscillator change the FOSC_HS to FOSC_INTOSC ; INTOSC oscillator: I/O function on CLKIN pin
This has a default speed of 500khz but you can change it up to 16mhz in your code by using the OSCCON instruction -see the datasheet page 62

I joint this header file in my program.
How to edit the header file ?

[example] I am using HS oscillator, how to select the FOSC?

Can i delete FOSC other options?

 

[bigdogguru]

No, you should not edit the device specific header file.

Only use in for reference to select the proper Configuration Bit Masks for the Config() compiler directives:

__CONFIG(1, FOSC_HS & PWRTE_ON & BOREN_OFF & WDT_OFF & MCLRE_ON & CP_OFF & CLOCKOUT_ON & IESO_OFF & FCMEN_OFF);
__CONFIG(2, WRT_OFF & VCAPEN_OFF & LVP_OFF & LPBOR_OFF & BORV_OFF & STVR_ON);

For example the Oscillator offers eight possible configuration options which can be used in the top Config() directive, FOSC_ECH, FOSC_ECM, FOSC_ECL, FOSC_INTOSC, FOSC_EXTRC, FOSC_HS, FOSC_XT or FOSC_LP.

Only one bitmask of a particular category can be include in the Config() directive at a time.

// Oscillator Selection
// ECH, External Clock, High Power Mode (4-20 MHz): device clock supplied to CLKIN pin
#define FOSC_ECH             0xFFFF
// ECM, External Clock, Medium Power Mode (0.5-4 MHz): device clock supplied to CLKIN pin
#define FOSC_ECM             0xFFFE
// ECL, External Clock, Low Power Mode (0-0.5 MHz): device clock supplied to CLKIN pin
#define FOSC_ECL             0xFFFD
// INTOSC oscillator: I/O function on CLKIN pin
#define FOSC_INTOSC          0xFFFC
// EXTRC oscillator: External RC circuit connected to CLKIN pin
#define FOSC_EXTRC           0xFFFB
// HS Oscillator, High-speed crystal/resonator connected between OSC1 and OSC2 pins
#define FOSC_HS              0xFFFA
// XT Oscillator, Crystal/resonator connected between OSC1 and OSC2 pins
#define FOSC_XT              0xFFF9

I use this PIC16f1527.h file.

#include <htc.h>
#include "sci.h"
#include "definitions.h"
#include "PIC16F1527.h"

include this PIC16f1527.h file in my program. But i got the following error
