Fl-artiklu tal-lum nixtieq naqsam magħkom proġett ġdid. Din id-darba huwa touch switch b'pannell tal-ħġieġ. L-apparat huwa kompatt, li jkejjel 42x42mm (il-pannelli tal-ħġieġ standard għandhom dimensjonijiet 80x80mm). L-istorja ta 'dan l-apparat bdiet żmien twil ilu, madwar sena ilu.
L-ewwel għażliet kienu fuq il-mikrokontrollur atmega328, iżda fl-aħħar kollox spiċċa bil-mikrokontrollur nRF52832.
Il-parti touch tal-apparat taħdem fuq ċipep TTP223. Iż-żewġ sensuri huma moqdija minn interruzzjoni waħda. Mħaddma minn batterija CR2477, permezz ta 'konvertitur boost fuq iċ-ċippa TPS610981 | .
L-apparat jimplimenta ċirkwit li jitfi l-enerġija bl-użu ta 'transistors b'effett ta' kamp. Wara li tagħfas il-buttuna, il-mikrokontrollur innifsu jinterċetta l-kontroll tal-qawwa u mbagħad il-buttuna tista 'tintuża għal modi ta' servizz (fil-każ tiegħi, dan huwa tgħaqqad ma 'apparati oħra, itfi l-enerġija u terġa' tiġi ssettjata għall-issettjar tal-fabbrika).
Hemm 2 LEDs rgb biex jindikaw stati u modi tas-servizz. Ġie miżjud ukoll emitter piezo biex jissimula klikk meta tmiss buttuni tat-touch u indikazzjoni tal-ħoss tal-modi tas-servizz. L-LEDs u l-emittent piezo jistgħu jinxtegħlu u jintfew fid-diskrezzjoni tal-utent. Dan isir permezz tal-kontrollur tad-dar intelliġenti billi jintbagħtu kmandi lil sensuri tekniċi; l-utent jista 'wkoll ibiddel l-intervalli biex jibgħat il-ħlas tal-batterija u l-livell tas-sinjal permezz tal-kontrollur tad-dar intelliġenti. Fil-każ tiegħi huwa .
Il-konsum fil-mod ta 'trażmissjoni huwa 7mA (250kbit, 10ms), il-konsum fl-irqad huwa 40µA, il-konsum fl-istat mitfi huwa inqas minn 1µA (= konsum tal-konvertitur boost fil-modalità "idle"). Rx, tx, konnettur swd għall-ipprogrammar huwa pprovdut. Jintuża konnettur minjatura 2x3p b'pitch ta '1.27. Adapter speċjali huwa magħmul għall-ipprogrammar.
Bħal dejjem, it-tħaddim tal-apparat huwa bbażat fuq il-protokoll . Dan is-swiċċ tat-touch huwa ppjanat li jintuża fis-sistema ta 'kontroll roller blind. Iżda b'mod ġenerali, l-applikazzjoni hija limitata biss mill-immaġinazzjoni tiegħek. Pereżempju, ibni (7 snin) diġà għamel 3 ordnijiet għal verżjonijiet tal-iswiċċ: biex jixgħel u jitfi d-dawl f'tojlit b'bathtub (se jkun immuntat baxx mill-art), biex jixgħel id-dawl f' kuritur twil u skur meta tivvjaġġa lejn toilet b'bathtub, u ieħor bħala komodina, biex tixgħel malajr id-dawl fil-kamra tiegħek sabiex il-monsters jaħarbu.
Il-każ kien tradizzjonalment stampat fuq printer SLA, l-apparat huwa minjatura, il-każ irriżulta li kien żgħir, l-użu ta 'din it-teknoloġija tal-istampar huwa ġġustifikat.
