Hello to all, can someone please help me to convert the following code from ATTiny85 to Pic 12f657?

------------------------------------------------

void setup() {
// initialize the digital pin as an output. We are using Pin 2 on the Attiny85 microcontroller

pinMode(2, OUTPUT);

digitalWrite(2, HIGH);// blink LEDs once to signal power on
delay(2000);
digitalWrite(2, LOW);
delay(7200000); // Wait 2 hours
}

void loop() {
digitalWrite(2, HIGH); // set the LED on
delay(1000); // wait for a second
digitalWrite(2, LOW); // set the LED off

delay(600000); //Wait 10 minutes
}

It not that hard give it a try.
pinMode(2, OUTPUT); would be TRISO = 0x0;
digitalWrite(2, HIGH); would be GPIO = 0x3;

so setup would look like
Rich (BB code):
void setup()
{
   CMCON = 0X7;  'turns off the comparator
   ANSEL = 0x0;    ' turns off the ADC
   TRISO = 0x0;    ' set's GPIO to outputs.
}
Now you add the config and the main code ok ? if you can't try to any way and I'll show you the rest and read this to http://ww1.microchip.com/downloads/en/devicedoc/41190c.pdf

Oh and one more thing you sure you don't have a 12f675 theres no 12f657 ?

Thanks! You were very helpfull!

Now I get a different problem with error: "Argument is out of range"

This is for:

Delay_ms(7200000);

It accepts only until 50000 for 4Mhz. I don't mind the timming but even i change it.. it's proportional with limits, and nothing really changes.

Is there any solution to that? can I change limits somehow?

Not really. You can put Delay_ms( ) into a loop to get the delay you wish or you can write your own delay function using unsigned long integers.

If you would tell me what compiler your using I could help you better

Here a little more code to look at.

Rich (BB code):
#include <xc.h>
void setup()
{
   CMCON = 0X7;  //turns off the comparator
   ANSEL = 0x0;  //turns off the ADC 
   TRISIO = 0x0; //set's GPIO to outputs   
}

void time_H()
{
	unsigned long int x;
	for(x=0;x<7200000;x++)  // the numbers will need to be based on clock
    {
	if ( x == 7200000 )
	break;
	}           
} 
void time_M()
{
	unsigned long int x;
	for(x=0;x<100000;x++)  // the numbers will need to be based on clock
    {
	if ( x == 100000 )
	break;
	}

           
} 
void main ()
{
 ; //user code here
}

Sure!, I use the:
---------------------------------------------
mikroC, mikroElektronika C compiler
for Microchip PIC microcontrollers
Version: 8.1.0.0
---------------
and the Easypic3 board
------------------------------------------------

I drop the timing for battery saving reasons to 0.3MHz.

The problems are the long delays,

Delay_ms(6600000); should be 2 hours

and

Delay_ms(300000); should be 5 minutes



I placed the setup above and this is the code i have so far without errors..

void setup()
{
CMCON = 0X7; //turns off the comparator
ANSEL = 0x0; //turns off the ADC
TRISIO = 0x0; //set's GPIO to outputs
}

void time_H()
{
unsigned long int x;
for(x=0;x<7200000;x++) // the numders will need to be based on clock
{
if ( x == 7200000 )
break;
}
}
void time_M()
{
unsigned long int x;
for(x=0;x<100000;x++) // the numders will need to be based on clock
{
if ( x == 100000 )
break;
}


}

void main() {

GPIO = 0xFF;
Delay_ms(100000);
GPIO = 0;
Delay_ms(50000);
GPIO = 0xFF;
Delay_ms(200000);
GPIO = 0;


Delay_ms(6600000);


do {
GPIO = 0xFF;
Delay_ms(20000);
GPIO = 0;
Delay_ms(100000);
GPIO = 0xFF;
Delay_ms(20000);
GPIO = 0;



Delay_ms(300000);

} while(1);
}
