Guhestina mini touch bi panelê camê li ser nRF52832

Di gotara îro de ez dixwazim projeyek nû bi we re parve bikim. Vê carê ew bi panelek cam veguhezek pêçek e. Amûra kompakt e, bi pîvana 42x42mm (panelên cama standard xwedî pîvanên 80x80mm in). Dîroka vê cîhazê demek dirêj berê, bi qasî salek berê dest pê kir.

Vebijarkên yekem li ser mîkrokontrolkerê atmega328 bûn, lê di dawiyê de ew hemî bi mîkrokontrolerê nRF52832 bi dawî bû.

Parçeya destikê ya cîhazê li ser çîpên TTP223 dimeşe. Her du senzor ji hêla yek navberê ve têne xizmet kirin. Ji hêla pîlê CR2477 ve, bi navgînek veguhezkerek bihêz a li ser çîpê TPS610981 ve hatî hêzdar kirin | datasheet.

Amûr bi karanîna transîstorên bandora zeviyê pêvekek hêzê vedike. Piştî pêlkirina bişkojkê, mîkrokontroller bixwe kontrola hêzê digire û dûv re bişkoj dikare ji bo modên karûbarê were bikar anîn (di rewşa min de, ev bi cîhazên din re têkildar e, elektrîkê qut dike û vedigere mîhengên kargehê).

Ji bo nîşankirina rewşan û awayên karûbarê 2 rgb LED hene. Di heman demê de emiterek piezo jî hatiye zêdekirin da ku klîkek dema ku bişkojkên destikê û nîşana deng a modên karûbarê destnîşan dike simule bike. LEDs û emitera piezo dikarin li gorî biryara bikarhêner werin vemirandin û girtin. Ev bi navgîniya kontrolkera xaniyê biaqil bi şandina fermanan ji senzorên teknîkî re tê kirin; bikarhêner di heman demê de dikare navberên şandina barkirina batterê û asta sînyalê jî bi navgîniya kontrolkera xaniyê jîr biguhezîne. Di doza min de ew e MAJORDOMO.

Vexwarina di moda veguheztinê de 7mA (250kbit, 10ms) e, vexwarina di xewê de 40µA ye, vexwarin di rewşa neçalak de ji 1μA kêmtir e (=bikaranîna veguhezkarê zêdeker di moda "bêkar" de). Ji bo bernamekirinê girêdana Rx, tx, swd tê peyda kirin. Têkiliyek piçûk 2x3p bi pileya 1.27 tê bikar anîn. Ji bo bernamekirinê adapterek taybetî tê çêkirin.

Mîna her gav, xebata amûrê li ser bingeha protokolê ye MySensors. Ev guhêrbar tê plansaz kirin ku di pergala kontrolkirina kor a roller de were bikar anîn. Lê bi gelemperî, serîlêdan tenê ji hêla xeyaliya we ve sînorkirî ye. Mînakî, kurê min (7 salî) jixwe 3 ferman ji bo guhertoyên guhêrbar çêkiriye: ronahiyê di tuwaletê de bi serşokê vekin û vemirînin (ew ê ji erdê nizm were çekirin), ronahiyê vekin. Korîdorek dirêj û tarî dema ku hûn diçin tuwaletek bi serşokê, û yekî din jî li kêleka nivînê, ji bo ku zû ronahiya odeya xwe vekin da ku cinawir birevin.

Doz bi kevneşopî li ser çapkerek SLA hate çap kirin, amûrek mînyatur e, kavil piçûk bû, karanîna vê teknolojiya çapkirinê rastdar e.
