Aktuálna revízia z 19:15, 23. február 2023
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
- Programovanie napr. cez USBtiny ISP
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

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
