Programming Attiny10 Microcontroller

[gauravkothari23]

Hi all..
I am working on a small project using attiny 10 microcontroller where i need to test the blink program initially.

#define F_CPU 8000000UL			// define it now as 1 MHz unsigned long


#include <avr/io.h>
#include <stdint.h>
#include <util/delay.h>

int main (void) 
{
	
	unsigned int i;
	CCP = 0xD8;
	//  CLKPS[3:0] sets the clock division factor
	CLKPSR = 0;
	
	for(i=0; i<=100; i++)
	{
	PORTB = 0b0000;		// TURN ON LED	
	_delay_ms(50);
	PORTB = 0b1111;		// TURN OFF LED						
	_delay_ms(50);
	}
}

Schamatic Attached.
i am using anduino nano to program attiny chip.
REF: https://junkplusarduino.blogspot.com/p/attiny10-resources.html
what my problem is...
my controller does not start. The LED is not blinking. i have even tried programming 4 to 5 boards, but non of them work.
can anybody please let me know what the problem is

Don't work on simulation ? Don't work on actual circuit ?
And more...you did not specify what compiler you are using.
BTW: You seemingly forgot to configure DDRB register.

Sorry...
i had configured but forgot to mention.

DDRB |= (1 << PB0);
DDRB |= (1 << PB2);

i am using atmel studio. and the it does not work on actual circuit.

Probably not your problem but remember that an embedded app does NOT have an OS to return to when it finishes (although it never should 'finish').
Typically such apps have a main loop that is infinite - typically written as 'while(1){...}'.
I would recommend that you replace the 'for' loop with such an infinite main loop. This way your code will have the proper structure for all future projects.

Hi.
Now I don’t have this chip, but before I did such a project and everything worked
