Mini touch switch kalawan panel kaca on nRF52832

Dina artikel dinten ieu abdi hoyong bagikeun sareng anjeun proyék anyar. waktos Ieu mangrupakeun switch touch ku panel kaca. Alatna kompak, ukuranana 42x42mm (panél kaca standar ukuranana 80x80mm). Sajarah alat ieu mimiti lila pisan, kira-kira sataun katukang.

Pilihan kahiji aya dina mikrokontroler atmega328, tapi tungtungna sadayana ditungtungan ku mikrokontroler nRF52832.

Bagian touch tina alat dijalankeun dina chip TTP223. Duanana sensor dilayanan ku hiji interupsi. Powered by batré CR2477, via converter dorongan dina chip TPS610981 | lembar data.

Alatna ngalaksanakeun sirkuit pareum nganggo transistor pangaruh lapangan. Saatos mencét tombol, mikrokontroler sorangan nyegat kontrol kakuatan teras tombolna tiasa dianggo pikeun modeu jasa (dina hal kuring, ieu dipasangkeun sareng alat anu sanés, mareuman kakuatan sareng ngareset kana setélan pabrik).

Aya 2 rgb LED pikeun nunjukkeun kaayaan sareng modeu jasa. A emitter piezo ogé geus ditambahkeun kana simulate a klik nalika noel tombol touch sarta indikasi sora tina modeu layanan. LEDs sareng piezo emitter tiasa dihurungkeun sareng mareuman ku kawijaksanaan pangguna. Hal ieu dilakukeun ngaliwatan controller home pinter ku ngirim paréntah ka sensor teknis; pamaké ogé bisa ngarobah interval pikeun ngirim muatan batré jeung tingkat sinyal ogé ngaliwatan controller home pinter. Dina hal kuring éta MAJORDOMO.

Konsumsi dina modeu ngirimkeun nyaéta 7mA (250kbit, 10ms), konsumsi nalika bobo 40µA, konsumsi dina kaayaan pareum kirang ti 1µA (=konsumsi konverter dorongan dina modeu "dianggurkeun"). Rx, tx, konektor swd pikeun programming disadiakeun. Konektor miniatur 2x3p kalayan pitch 1.27 dianggo. A adaptor husus dijieun pikeun programming.

Sakumaha biasa, operasi alat dumasar kana protokol MySensors. switch touch ieu rencanana dipaké dina roller sistem kontrol buta. Tapi sacara umum, aplikasina ngan ukur ku imajinasi anjeun. Contona, putra abdi (7 taun) geus nyieun 3 pesenan pikeun versi switch: ngahurungkeun jeung mareuman lampu di toilet jeung bak mandi (eta bakal dipasang low ti lantai), ngahurungkeun lampu dina koridor panjang tur poék lamun iinditan ka WC kalayan bak mandi, sarta séjén salaku bedside, pikeun gancang ngahurungkeun lampu di kamar anjeun ku kituna monster kabur.

Kasus ieu sacara tradisional dicitak dina printer SLA, alatna miniatur, kasusna tétéla leutik, panggunaan téknologi percetakan ieu diyakinkeun.

Témbongkeun modél dicitak

Magnét dipasang dina wadah sareng panutup kompartemen batré.
