V današnjem članku želim z vami deliti nov projekt. Tokrat gre za stikalo na dotik s stekleno ploščo. Naprava je kompaktna, dimenzij 42x42 mm (standardne steklene plošče imajo dimenzije 80x80 mm). Zgodovina te naprave se je začela že davno, pred približno enim letom.
Prve možnosti so bile na mikrokrmilniku atmega328, na koncu pa se je vse končalo pri mikrokrmilniku nRF52832.
Del naprave na dotik deluje na čipih TTP223. Oba senzorja ima ena prekinitev. Napajanje z baterijo CR2477 preko ojačevalnega pretvornika na čipu TPS610981 | .
Naprava izvaja izklopno vezje z uporabo tranzistorjev z učinkom polja. Po pritisku na gumb mikrokrmilnik sam prestreže krmiljenje moči in nato lahko gumb uporabimo za servisne načine (v mojem primeru je to seznanjanje z drugimi napravami, izklop napajanja in ponastavitev na tovarniške nastavitve).
Obstajata 2 rgb LED za prikaz stanj in servisnih načinov. Dodan je bil tudi piezo oddajnik za simulacijo klika ob dotiku gumbov na dotik in zvočno indikacijo servisnih načinov. LED diode in piezo oddajnik se lahko vklopijo in izklopijo po lastni presoji uporabnika. To poteka prek krmilnika pametnega doma s pošiljanjem ukazov tehničnim senzorjem, uporabnik pa lahko spreminja tudi intervale pošiljanja napolnjenosti baterije in nivo signala prav tako prek krmilnika pametnega doma. V mojem primeru je .
Poraba v načinu oddajanja je 7mA (250kbit, 10ms), poraba v mirovanju je 40µA, poraba v izklopljenem stanju je manjša od 1µA (=poraba ojačevalnega pretvornika v načinu “idle”). Rx, tx, swd konektor za programiranje je na voljo. Uporabljen je miniaturni konektor 2x3p s korakom 1.27. Za programiranje je izdelan poseben adapter.
Kot vedno, delovanje naprave temelji na protokolu . To stikalo na dotik je predvideno za uporabo v sistemu za upravljanje rolet. Toda na splošno je uporaba omejena le z vašo domišljijo. Moj sin (7 let) je na primer že naredil 3 naročila za različice stikala: za prižig in ugasnitev luči v WC-ju s kadjo (montirana bo nizko od tal), za prižig luči v dolg in temen hodnik, ko potujete do stranišča s kadjo, in še eno kot posteljno omarico, da hitro prižgete luč v svoji sobi, da pošasti zbežijo.
Ohišje je bilo tradicionalno natisnjeno na tiskalniku SLA, naprava je miniaturna, ohišje se je izkazalo za majhno, uporaba te tehnologije tiskanja je upravičena.

Magneti so prilepljeni v ohišje in pokrov predala za baterije.
