This was another Attiny micro that I had in the tool box, so I decided to create a simple DIY development board (more on that later) and create some basic examples to play around with
Not a very exciting example, just the usual flashing LED example with a couple of LEDs connected to our attiny, lets look at the schematic.
Schematic
Code
We wrote this example in Atmel Studio. Fairly basic stuff here, set PORT D as outputs, switch on the LED connected to PD0, then the PD1 LED on, both LEDS on, then switch them off.
#define F_CPU 1000000UL // 1 MHz #include <avr/io.h> #include <util/delay.h> // int main(void) { // LEDs are on portD 0 and 1 DDRD = 0xff; while(1) { PORTD = 0x01; _delay_ms(500); PORTD = 0x02; _delay_ms(500); PORTD = 0x03; _delay_ms(500); PORTD = 0x00; _delay_ms(500); } }
