Esihlokweni sanamuhla ngifuna ukwabelana nawe ngephrojekthi entsha. Lesi sikhathi isishintshi sokuthinta esinephaneli yengilazi. Idivayisi ihlangene, ikala 42x42mm (amaphaneli engilazi ajwayelekile anobukhulu obungu-80x80mm). Umlando wale divayisi waqala kudala, cishe unyaka odlule.
Izinketho zokuqala beziku-atmega328 microcontroller, kodwa ekugcineni konke kwaphela nge-nRF52832 microcontroller.
Ingxenye yokuthinta yedivayisi isebenza kuma-chips e-TTP223. Zombili izinzwa zinikezwa isiphazamiso esisodwa. Inikwa amandla ibhethri le-CR2477, nge-boost converter ku-chip ye-TPS610981 | .
Idivayisi isebenzisa isekethe yokuvala amandla isebenzisa ama-transistor asebenza endaweni. Ngemuva kokucindezela inkinobho, i-microcontroller ngokwayo ibamba ukulawulwa kwamandla bese inkinobho ingasetshenziswa kumamodi wesevisi (esimweni sami, lokhu kuhlanganisa namanye amadivaysi, ukuvala amandla nokusetha kabusha kuzilungiselelo zasefekthri).
Kunama-LED angu-2 rgb okubonisa izimo nezindlela zesevisi. I-piezo emitter nayo yengeziwe ukuze ilingise ukuchofoza lapho uthinta izinkinobho zokuthinta kanye nenkomba yomsindo yamamodi esevisi. Ama-LED kanye ne-piezo emitter ingavulwa futhi ivalwe ngokubona komsebenzisi. Lokhu kwenziwa ngesilawuli sasekhaya esihlakaniphile ngokuthumela imiyalo kuzinzwa zobuchwepheshe; umsebenzisi angakwazi futhi ukushintsha izikhawu zokuthumela ukushajwa kwebhethri nezinga lesignali futhi ngesilawuli sasekhaya esihlakaniphile. Endabeni yami kunjalo .
Ukusetshenziswa kumodi yokudlulisa kungu-7mA (250kbit, 10ms), ukusetshenziswa ebuthongweni ngu-40Β΅A, ukusetshenziswa esimweni sokucisha kungaphansi kuka-1Β΅A (=ukusetshenziswa kwesiguquli se-boost kumodi "engenzi lutho"). I-Rx, tx, isixhumi se-swd sokuhlela sinikezwe. Kusetshenziswa isixhumi esincane esingu-2x3p esine-pitch engu-1.27. I-adaptha ekhethekile yenzelwe ukuhlela.
Njengokuvamile, ukusebenza kwedivayisi kusekelwe kuphrothokholi . Lokhu kushintsha kokuthinta kuhlelwe ukuthi kusetshenziswe ohlelweni lokulawula i-roller blind. Kodwa ngokuvamile, isicelo sinqunyelwe kuphela umcabango wakho. Isibonelo, indodana yami (iminyaka engu-7 ubudala) isivele yenze ama-oda angu-3 wezinguqulo zokushintsha: ukuvula nokucisha isibani endlini yangasese enobhavu wokugeza (izofakwa phansi isuka phansi), ikhanyise ukukhanya umhubhe omude nomnyama lapho uya endlini yangasese enobhavu, nenye njengendawo yombhede, ukuze ukhanyise ngokushesha isibani ekamelweni lakho ukuze izilo zibaleke.
Icala laliphrintiwe ngokwesiko kuphrinta ye-SLA, idivayisi iyingcosana, icala lavela laba lincane, ukusetshenziswa kwalobu buchwepheshe bokuphrinta kufanelekile.
Buka imodeli ephrintiwe
Omazibuthe banamathiselwe kukesi kanye nesembozo sengxenye yebhethri.
Amavidiyo anokuhlolwa kwale divayisi:
