som si spustil s\u00e9riov\u00fa konzolu a prihl\u00e1sil sa cez \u0148u. V\u0161etko fungovalo, tak
som to znova porozp\u00e1jal a pustil to z hlavy. Samozrejme, \u017ee som konzolu
zabudol vypn\u00fa\u0165 a str\u00e1vil som dos\u0165 ve\u013ea \u010dasu zis\u0165ovan\u00edm, pre\u010do mi d\u00e1ta te\u010d\u00fa len
jedn\u00fdm smerom a aj to nie \u00faplne spo\u013eahlivo. Tu \u010fakujem Pavlovi Vymet\u00e1lkovi,
ktor\u00e9mu debug probl\u00e9mu trval asi 1 min\u00fatu (spo\u010d\u00edvalo to v spojen\u00ed pinu 2 a 3 na

Na PC teda pou\u017e\u00edvam Picocom (znova v\u010faka Pavlovi, je to s\u00e9riov\u00fd

si nie som ist\u00fd v akom stave je prenos (vr\u00e1tim sa k tomu nesk\u00f4r). V\u00fdpis nastavenia portu z Picocomu:<\/p>\n\n\n\n
