Hello guys,
I have problem with my new ATmega168. I bought new chip with no arduino bootloader and, create circuit and followed steps as described here:
http://www.micahcarrick.com/tutorials/avr-microcontroller-tutorial/getting-started.html
(schema is too atached).
I tried too blink sketch compiled with arduino ide, and manually compiled and uploaded this:
#define F_CPU 1000000UL
#include <avr/io.h>
#include <util/delay.h>
int
main (void)
{
DDRB |= _BV(DDB0);
while(1)
{
PORTB ^= _BV(PB0);
_delay_ms(500);
}
}
Everything seems to by fine. Chip was programmed and verified correctly (i try to use avrdude and avrstudio).
Output here:
avrdude -p m168 -c avrispmkII -P usb -e -U flash:w:blik.hex

avrdude done. Thank you.
But after reset no led blink on any pin. Where can be problem? I changed the fuse bits to this values (disable bootloader):
lfuse: 0x62, hfuse: 0xdf, efuse:0xfe.
Can anybody help me please? I check circuit 3x. Thanks a lot... Some files attached
