Rychly zoznam projektov a stranok k programovaniu ATtiny (vid aj projekty DTV)
- Pighixxx Pinout diagram https://pighixxx.tumblr.com/image/93202369320
- ATtiny Core library for Arduino https://github.com/SpenceKonde/ATTinyCore
Strasne vela navodov je na strankach Roba Ulbrichta https://www.arduinoslovakia.eu/
Napriklad:
- Blik
- Tlacitko
- PWM na LEDky
- Generator zvukov
- ATtiny85 a displej TM1637
- 10-bitové PWM
- Jednoducha hracka
Nelineárna citlivosť ľudského oka
SparkFun
- ATtiny Guide
- Quick Reference Sheet - vytlacit na cvika
- RGB sviecka - blikajuce 3 RGB
- Detektor pretecenia vody na baterku CR3202 aj s modifikaciami programu
Technoblogy
- Zoznam
- Push-Button On/Off Switches
- Playing Notes on the ATtiny85
- I2C
- InfraRed Remote
Dalsie:
- Da sa programovat v Blockly cez simulator v TinkerCADe
- Vseobecne
- http://homemadehardware.com/guides/programming-an-attiny85/
- Vseobecne
- SPI Master aj Slave
- I2C Master aj Slave !!!
- RGB demo
- Power save rezimy su dobre opisane (aj s projektom na casovac s pipakom): http://www.technoblogy.com/show?KX0
- Sapien IR CTRL Palov projekt s USB aj IR
Problemy
- 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
Fuses

Program na jednoduché blikanie LEDkou
#include <avr/io.h>
/* Pripojenie periferii k vyvojovej doske Arduino: */
#define LED1 PB5 // zabudovana dioda
#define SW1 PB4
int main(void)
{
/*** ToDo ***/
return 0;
}
#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
}
