Step 6Program the AVR Tiny Microcontroller
The AVR is programmed using STK500 in High Voltage Serial Programming (HVSP) mode. The fuse settings are as shown here. The C code is short and sweet:
#include<avr/io.h>
volatile uint8_t i=0;
int main(void)
{
DDRB=0b00001000;
PORTB=0b00000000;
while(1)
{
PORTB=0b00000000;
for(i=0;i<254;i++);
PORTB=0b00001000;
for(i=0;i<254;i++);
}
return 0;
}
#include<avr/io.h>
volatile uint8_t i=0;
int main(void)
{
DDRB=0b00001000;
PORTB=0b00000000;
while(1)
{
PORTB=0b00000000;
for(i=0;i<254;i++);
PORTB=0b00001000;
for(i=0;i<254;i++);
}
return 0;
}

I was wondering why you used HVSP to program this with the STK500 and not using the SPI (SCK, MISO, MOSI) on PB0-2?
