Problemy

Na ake najmensie napatie to este pracuje? Bude modra LED svietit? Minimalizuj prudovu zataz.
Ked budu programovacie piny obsadene LED alebo tlacitkom tak moze byt problem, trocha sa tomu venuju tuto: https://www.kanda.com/avr-isp-circuits.html
- Alternativou moze byt UPDI Unified Program and Debug Interface (UPDI) programator, ktory pouziva len jeden pin - podobne ako DebugWire.
- Taky programator sa da spravit z Arduino Nano napr. https://daumemo.com/diy-updi-usb-programmer-which-can-be-made-with-cheap-hardware/
- Zakazat RESET (aby bol k dispozicii dalsi pin) nema zmysel, pretoze bez RESETu sa neda cip preprogramovat inak ako v HV programatore

1. Program na jednoduché blikanie LEDkou

Program v grafickom jazyku Blockly (TinkerCAD).

AVR CArduinoAssembler

##define F_CPU 8000000UL  // toto je lepsie vlozit do parametrov pre kompilator

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

#define LED1  PB2  // pripojena dioda 

int main(void)
{
    DDRB |= (1 << LED1);  // set pin as OUTPUT	
	
    while(1)
    {
         PORTB |=  (1<<LED1);          // ... tak rozsviet LED, t.j. set PB5 na log. 1 
	     _delay_ms(200);
         PORTB &= ~(1<<LED1);         // zhasni LED, t.j. clear PB5 na log. 0
	  	 _delay_ms(2000);
    }
}

#define LEDpin 4  //aby nekolidovalo s programatorom, takto sa da trvale nechat pripojeny

void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LEDpin, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LEDpin, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(100);                       // wait for a second
  digitalWrite(LEDpin, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}

2. Tlačítko a LED

Program v grafickom jazyku Blockly (TinkerCAD).

ArduinoAVR CAssembler

#define LED1 2

void setup()

  pinMode(LED1,OUTPUT);
}

void loop()

      digitalWrite(LED1, HIGH);
  else 
      digitalWrite(LED1, LOW);
  
}

#define set_bit(ADDRESS,BIT) (ADDRESS |= (1<<BIT))
#define clear_bit(ADDRESS,BIT) (ADDRESS &= ~(1<<BIT))


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

#define LED1  PB2  // pripojena dioda 
#define SW1   PB1  // pripojene tlacitko

int main(void)
{
    DDRB |= (1 << LED1);  // set LED1 pin as OUTPUT	
	DDRB &= ~(1<<SW1);    // set SW1 pin as INPUT (not necessary, default)
	PORTB |= (1<<SW1);    // SW1 pull-up ON
	
    while(1)
    {
      if ( bit_is_clear(PINB, SW1) )   // ak je stlacene tlacitko SW1
 	    set_bit(PORTB,LED1);           // LED1 = log.1
      else                             // inak
	    clear_bit(PORTB,LED1);         // LED1 = log.0
