1. Skontroluj z\u00e1kladn\u00e9 veci:<\/strong><\/p>\n\n\n\n

\n
USB k\u00e1bel:<\/strong> Uisti sa, \u017ee pou\u017e\u00edva\u0161 kvalitn\u00fd USB k\u00e1bel, ktor\u00fd pren\u00e1\u0161a d\u00e1ta, a nie iba nap\u00e1janie. Sk\u00fas in\u00fd USB k\u00e1bel, ak m\u00e1\u0161 k dispoz\u00edcii.<\/li>\n\n\n\n
Pripojenie:<\/strong> Skontroluj, \u010di je k\u00e1bel pevne zasunut\u00fd do dosky RP2040 aj do USB portu na tvojom po\u010d\u00edta\u010di. Sk\u00fas pou\u017ei\u0165 in\u00fd USB port na po\u010d\u00edta\u010di.<\/li>\n\n\n\n
Nap\u00e1janie:<\/strong> Uisti sa, \u017ee doska dost\u00e1va dostato\u010dn\u00e9 nap\u00e1janie. Niektor\u00e9 dosky m\u00f4\u017eu vy\u017eadova\u0165 extern\u00e9 nap\u00e1janie pre pln\u00fa funk\u010dnos\u0165, hoci pre s\u00e9riov\u00fa komunik\u00e1ciu by zvy\u010dajne malo sta\u010di\u0165 nap\u00e1janie z USB.<\/li>\n<\/ul>\n\n\n\n\n\n\n\n
2. Re\u017eim Bootloader (BOOTSEL):<\/strong><\/p>\n\n\n\n
\n
RP2040 m\u00e1 zabudovan\u00fd bootloader, do ktor\u00e9ho sa d\u00e1 dosta\u0165 podr\u017ean\u00edm tla\u010didla BOOTSEL<\/strong> (alebo podobn\u00e9ho ozna\u010den\u00e9ho tla\u010didla) po\u010das prip\u00e1jania dosky k po\u010d\u00edta\u010du cez USB.<\/li>\n\n\n\n
Podr\u017e tla\u010didlo BOOTSEL<\/strong>, pripoj USB k\u00e1bel a po nieko\u013ek\u00fdch sekund\u00e1ch tla\u010didlo uvo\u013eni.<\/li>\n\n\n\n
Po\u010d\u00edta\u010d by mal rozpozna\u0165 nov\u00e9 zariadenie, \u010dasto ako USB Mass Storage Device (akoby USB k\u013e\u00fa\u010d). Ak sa toto objav\u00ed, je to dobr\u00fd znak. Aj ke\u010f sa neobjav\u00ed s\u00e9riov\u00fd port, t\u00e1to met\u00f3da m\u00f4\u017ee by\u0165 potrebn\u00e1 na nahranie firmv\u00e9ru, ktor\u00fd s\u00e9riov\u00fd port spr\u00edstupn\u00ed.<\/li>\n\n\n\n
<\/li>\n<\/ul>\n\n\n\n
3. Nahranie firmv\u00e9ru:<\/strong><\/p>\n\n\n\n
\n
Doska RP2040 bude fungova\u0165 ako s\u00e9riov\u00fd port len vtedy, ak m\u00e1 nahran\u00fd firmv\u00e9r, ktor\u00fd t\u00fato funkciu implementuje.<\/li>\n\n\n\n
Ak sa ti podarilo dosta\u0165 dosku do re\u017eimu BOOTSEL a po\u010d\u00edta\u010d ju rozpoznal ako \u00falo\u017eisko, sk\u00fas nahra\u0165 jednoduch\u00fd program (napr\u00edklad z Arduino IDE, pr\u00edklad „Blink“ upraven\u00fd pre s\u00e9riov\u00fa komunik\u00e1ciu alebo in\u00fd jednoduch\u00fd s\u00e9riov\u00fd pr\u00edklad) skompilovan\u00fd do form\u00e1tu .uf2<\/code>. Jednoducho pretiahni .uf2<\/code> s\u00fabor na zobrazen\u00fd USB disk. Po nahran\u00ed sa doska re\u0161tartuje a mal by sa objavi\u0165 s\u00e9riov\u00fd port.<\/li>\n\n\n\n
S\u00fabor .uf2<\/code> vytvor\u00ed\u0161 v Arduino IDE cez Sketch -> Exportova\u0165 kompilovan\u00e9 s\u00fabory. Po kompil\u00e1cii n\u00e1jde\u0161 v\u00fdsledn\u00e9 s\u00fabory v zlo\u017eke projektu a podadres\u00e1ri „build“.<\/li>\n<\/ul>\n\n\n\n<\/p>\n","protected":false},"excerpt":{"rendered":" 1.
