BOOTSEL+ NYOMÓGOMB bekötése, használata.
Erre azért van szükség, hogy ne kelljen az USB portot folyamatosan a raspberry pi pico-n ki-be dugdosni, huzogatni.
  • BEKÖTÉSE:
  • HASZNÁLAT:
    • megnyomni a NYOMÓGOMB-ot majd a picon a BOOTSELgombot, aztán felengedni a NYOMÓGOMB-ot majd a BOOTSEL gombot 
  • ezután megjeleni a pico meghajtó ahova bemásolhatjuk az elkészített. UF2 fájl-t
