Yn it artikel fan hjoed wol ik in nij projekt mei jo diele. Dizze kear is it in touch switch mei in glêzen paniel. It apparaat is kompakt, mjitten 42x42mm (standert glêzen panielen hawwe ôfmjittings 80x80mm). De skiednis fan dit apparaat begon in lange tiid lyn, sawat in jier lyn.
De earste opsjes wiene op 'e atmega328 mikrocontroller, mar op it lêst einige it allegear mei de nRF52832 mikrocontroller.
It touch diel fan it apparaat rint op TTP223 chips. Beide sensoren wurde betsjinne troch ien ûnderbrekking. Oandreaun troch in CR2477 batterij, fia in boost converter op de TPS610981 chip | .
It apparaat ymplementearret in power-off circuit mei fjildeffekttransistors. Nei it drukken op de knop, ûnderskept de mikrocontroller sels machtkontrôle en dan kin de knop brûkt wurde foar tsjinstmodi (yn myn gefal is dit keppeljen mei oare apparaten, it útskeakeljen fan 'e macht en weromsette nei fabriekynstellingen).
D'r binne 2 rgb LED's foar it oanjaan fan steaten en tsjinstmodi. In piezo-emitter is ek tafoege om in klik te simulearjen by it oanreitsjen fan touchknoppen en lûdsindikaasje fan tsjinstmodi. De LED's en piezo-emitter kinne wurde yn- en útskeakele nei it ynsjoch fan de brûker. Dit wurdt dien fia de smart home controller troch it ferstjoeren fan kommando's nei technyske sensoren; de brûker kin ek de yntervallen feroarje foar it ferstjoeren fan batterijlading en sinjaalnivo ek fia de smart home controller. Yn myn gefal is it .
Konsumpsje yn ferstjoermodus is 7mA (250kbit, 10ms), konsumpsje yn sliep is 40µA, konsumpsje yn 'e út-status is minder dan 1µA (= konsumpsje fan' e boostkonverter yn "idle" modus). Rx, tx, swd-ferbining foar programmearring wurdt levere. In miniatuer 2x3p-ferbining mei in pitch fan 1.27 wurdt brûkt. In spesjale adapter is makke foar programmearring.
Lykas altyd is de wurking fan it apparaat basearre op it protokol . Dizze touch-switch is pland om te brûken yn it kontrôlesysteem foar rollerblinden. Mar yn 't algemien wurdt de applikaasje allinich beheind troch jo ferbylding. Bygelyks, myn soan (7 jier âld) hat al 3 oarders makke foar skeakelferzjes: it ljocht yn in húske mei in badke oan en útsette (it sil leech fan 'e flier wurde monteare), it ljocht yn in lange en tsjustere korridor as jo reizgje nei in húske mei in bad, en in oar as bedside, foar fluch ynskeakelje it ljocht yn dyn keamer sadat de meunsters rinne fuort.
De saak waard tradisjoneel printe op in SLA-printer, it apparaat is miniatuer, de saak blykte lyts te wêzen, it brûken fan dizze printtechnology is rjochtfeardige.

Magneten wurde gelijmd yn 'e saak en it deksel fan it batterijfak.
