ATtiny404 code upload and board installation guide

Customer:

How do I upload code to the ATtiny404? There aren’t many tutorials for these newer ATtiny microcontrollers. Could you provide instructions on how to install the ATtiny board and how to upload code using Arduino or dasduino, or create a tutorial if possible?

Pozdrav, zanima me kako uploadati kod na attiny404, nema nešto previše tutoriala za ove nove attiny microcontrollere. Ako nije problem može upute kako instalirati attiny board i kako poslati kod preko arduina ili dasduina ili ako nije problem napraviti tutorial.

Hvala!

Explore the “Arduino as ISP” method for uploading code - this uses another Arduino (or dasduino) to help transfer code to the ATtiny. Here’s a useful reference: How to Program an Attiny85 Using a Arduino Uno : 7 Steps - Instructables

For board definitions (how to install the ATtiny board), I recommend megaTinyCore: GitHub - SpenceKonde/megaTinyCore: Arduino core for the tinyAVR 0/1/2-series - Ones's digit 2,4,5,7 (pincount, 8,14,20,24), tens digit 0, 1, or 2 (featureset), preceded by flash in kb. Library maintainers: porting help available! · GitHub - check the Installation.md file and the “manual installation” section. You can also install it more easily via the board manager URL, though that link isn’t working at the moment.

putem korisničke podrške ti ne mogu napisati detaljan tutorial, ali evo nekih korisnih smjernica:
Istraži “Arduino as ISP” način uploada koda, ovo uključuje drugi Arduino (ili dasduino) koji ti pomaže prenijeti kod na ATTINY, evo jedan koristan link How to Program an Attiny85 Using a Arduino Uno : 7 Steps - Instructables Za board definitione (kako instalirati ATTINY board) preporučujem megaTinyCore: GitHub - SpenceKonde/megaTinyCore: Arduino core for the tinyAVR 0/1/2-series - Ones's digit 2,4,5,7 (pincount, 8,14,20,24), tens digit 0, 1, or 2 (featureset), preceded by flash in kb. Library maintainers: porting help available! · GitHub - pogledaj Installation.md i “manual installation” - inače se može puno lakše instalirati preko board manager URL-a ali taj link za sada ne radi i otvorio sam im GitHub issue za to da poprave
