  1. Burning bootloader [DISCLAIMER: If fuse is already burned, ATtiny can be programmed only with 12V programmer]
  2. 1. Awesome video tutorial: https://www.youtube.com/watch?v=FI3s4d2I1eQ
  3. 2. Go to: https://github.com/micronucleus/micronucleus to grab your self bootloader [we will move it to newfolder]
  4. 3. My own 100% working bootloader: https://uloz.to/!tksqJt9EcIo3/t85-100-working-hex [we will move it to new folder]
  5. 4. Use arduino UNO (others can be used to) as arduino ISP programmer.
  6. a. Load ArduinoISP program on arduino
  7. b. Upload program to arduino [in this case UNO]
  8. 5. Connect ATtiny85 with arduino
  9. Arduino +5V -> ATtiny VCC
  10. Arduino GND -> ATtiny GND
  11. Arduino Pin 10 -> ATtiny P5 [reset pin, If you already burned fuse, you have to use 12V programmer]
  12. Arduino Pin 11 -> Attiny P0
  13. Arduino Pin 12 -> ATtiny P1
  14. Arduino Pin 13 -> ATtiny P2
  15. 6. Tools -> Board -> ATtiny25/45/85 [depends on your ATtiny board]
  16. 7. Tools -> Processor -> Attiny85
  17. 8. Tools -> Clock -> Internal 16MHz
  18. 7. Tools -> Programmer -> Arduino as ISP
  19. 8. Open -> Basics -> Blink
  20. 9. Change every "LED_BUILTIN" to "1" [ATtiny board does not have built in led. Instead it is using pin1 for blink]
  21. 10. Click "Upload"
  22. 12. If your ATtiny85 starts to blink, you are good to go [if not, there is a mistake somewhere]
  23. 13. Find your Arduino folder [folder where Arduino IDE is installed]
  24. 14. My case: O:\Program Files (x86)\Arduino [in reality my case is: O:\Windows\Plocha\Arduino\arduino\hardware\tools\avr/bin/avrdude -CO:\Windows\Plocha\Arduino\arduino\hardware\tools\avr/etc/avrdude.conf -v -pattiny85 -cstk500v1 -PCOM7 -b19200 -Uflash:w:O:\Windows\Plocha\Arduino/t85_100%_working.hex:i -U lfuse:w:0xe1:m -U hfuse:w:0xdd:m -U efuse:w:0xfe:m]
  25. 15. Copy "Arduino" folder to your desktop [becuase we dont want any spaces in address]
  26. 16. Find in "Arduino" file called "averdude.exe" and copy its path -> C:\Desktop\Arduino\hardware\tools\avr\bin\averdude.exe [you might have different address]
  27. 17. Open CMD and type path to averdude: [change \avr\bin\averdude.exe to \avr/bin/averdude]
  28. C:\Desktop\Arduino\hardware\tools\avr/bin/averdude
  29. 18. Dont hit entre and continue typing: " " "-C""C:\Desktop\Arduino\hardware\tools\avr/etc/averdude.conf"
  30. C:\Desktop\Arduino\hardware\tools\avr/bin/averdude -CC:\Desktop\Arduino\hardware\tools\avr/bin/averdude.conf
  31. 19. Dont hit enter.We still need to add some other commands:" -v -pattiny85 -cstk500v1 -PCOM7 -b19200 -Uflash:w:C:\Desktop\Arduino/t85_100%_working.hex:i -U lfuse:w:0xe1:m -U hfuse:w:0xdd:m -U efuse:w:0xfe:m"
  32. C:\Desktop\Arduino\hardware\tools\avr/bin/averdude -CC:\Desktop\Arduino\hardware\tools\avr/bin/averdude.conf -v -pattiny85 -cstk500v1 -PCOM7 -b19200 -Uflash:w:C:\Desktop\Arduino/t85_100%_working.hex:i -U lfuse:w:0xe1:m -U hfuse:w:0xdd:m -U efuse:w:0xfe:m
  33.  
  34. a. Change PCOM to port which arduino UNO is connected to
  35. b. Move your downloaded bootloader to "Arduino" folder
  36. c. Rename "t85_100%_working.hex" to name of your downloaded bootloader
  37. 20. Hit enter
  38. 21. If everything goes well, you should see this in CMD:
