Sveiki visi,
gal galite padeti. Ant arduino noriu pasileisti rato laiko laikroduka. Programos kodas "skolintas" ir siektiek pritemptas prie mano idejos. Programa kaip ir veikia, bet nesualvoju kaip padaryti kad skaiciuotu tukstantasias sekundes dalis. Gal kas paprotins kaip padaryti. Yra du mygtukai, vienas paleidzia ir sustabdo, o kitas reset i 00:00:00
P.S. programuoti nemoku, vairuoti geriau sekasi. Irenginukas veikia bet norisi patobulinti.
Atsiprasau uz diletantiskus klausimus

Realiai tai jau viskas padaryta, ir darau sofware update tik  tik realybeje as naudoju I2c LCD moduliuka kad maziau laiduku butu. O pavyzdyje taip pakoriagaves kad galeciau pasitikrinti ant TINKERCAD simuliatoriaus ar kaip ji pavadinti.
Aciu, uz koda. pameginsiu pasigilinti ir pritaikyti |

sveiki, vel atejo ikvepimas programinti Pataisiau kaip noreciau kad veiktu isvedimas ir koks butu tikslumas ( tukstantoji sekundes dalis )
Irasius programulke i arduina, viskas veikia, taciau ka cia skaiciuoja nerealus laikas yra. Manau kad cia tickClock su funkcija milis ta "tika" apraso ir kas kiek laiko jis buna. Bet nzn kaip cia patvarkyti kad "tikas" butu kas 1ms.

| tai paprastai valdiklis tau tiksliai 1ms neislaikys. nes vykdant programa uztrunka tam tikra kieki laiko. tau reiketu TIMER pradėti naudoti, kuris sustoja vykdyti programa ivykdo kas yra timer aprasyta (pvz laikas++; prideda 1 ms) ir toliau sukasi programa. |

Gal galetumete issamiau papasakoti, as programuoti visai nemoku. Tiesiog rasta programa pritempti noriu iki man norimo varianto.
Siaip jei skaiciuoja programa, tik desimtasias ir simtasias viskas OK . Bet kai dadejau kad skaiciuotu ir tukstantaja dalį sekundes veikia jau kreivai.
Tikslumas yra toks
10 s realaus laiko yra 00:00:600 mano laikmacio
Tiksliai veikianti programa skaiciuojanti simtasias ir desimtasias sekundes dalis yra pirmame poste. |
