I-ZSWatch, i-smartwatch yoyilo lwasimahla esekwe kwi-Zephyr OS

Isanda kukhutshwa kwayeNdivule uphuhliso lweprojekthi yeZSWatch, oluluphuhliso lwewotshi ehlakaniphile esekelwe kwi-Nordic Semiconductor nRF52833 chip, exhotyiswe nge-ARM Cortex-M4 microprocessor kwaye iyahambelana neBluetooth 5.1.

Kuyakhankanywa ukuba I-smartwatch-specific-specific software and hardware ziphuhliswa ngokukodwa kwiprojekthi, ukusukela kuyilo lweskim kunye nePCB (kwifomathi ye-kicad) inikezelwe kwindawo yokugcina kwaye iyafumaneka ukukhuphela, kunye nemodeli yoshicilelo lwetyala kunye nesikhululo sokumisa kumshicileli we-3D.

Isoftware isekwe kwiZephyr RTOS evulekileyo exhasa ukudityaniswa kwee-smartwatches kunye nee-smartphones ezisekwe kwiqonga le-Android.

Amaqhosha amathathu anikezelwa ukulawula, kwaye ikristale yesafire isetyenziselwa ukukhusela isikrini. Okwesibini, imodeli ephuculweyo nayo iyaphuhliswa, ihlukaniswe ngokusetyenziswa kwe-nRF5340 chip esebenza ngakumbi esekwe kwiprosesa ye-ARM Cortex-M33 kunye nobukho besikrini sokuchukumisa.

Kwicala le isoftwe, ibhalwe ngolwimi C kwaye isebenza phantsi kwenkqubo yokusebenza ngexesha lokwenyani (RTOS) track .iphuhliswe kwizixhobo ze-IoT phantsi kwenkxaso ye-Linux Foundation ngegalelo elivela kwi-Intel, i-Linaro, i-NXP Semiconductors/Freescale, i-Synopsys, kunye ne-Nordic Semiconductor.

Undoqo weZephyr eyilelwe ukusebenzisa izixhobo ezincinci (ukusuka kwi-8 ukuya kwi-512 KB ye-RAM). Inye kuphela indawo yeedilesi ekwabelwana ngazo kwihlabathi jikelele (i-SASOS) ebonelelweyo kuzo zonke iinkqubo.

Isicelo-ikhowudi ethile idityaniswe ne-kernel ethile yesicelo ukwenza i-monolithic ephunyeziweyo eya kulayishwa kwaye iqhutywe kwi-hardware ethile. Zonke izixhobo zenkqubo zimiselwa ngexesha lokuqokelela kwaye kuphela ezo mpawu zekernel ezifunekayo ukuqhuba isicelo zibandakanyiwe kumfanekiso wenkqubo.

Kukwafanelekile ukukhankanya ukuba malunga nongqamaniso kunye nezixhobo ze-Android, kukhankanyiwe ukuba kukho i-app egqwesileyo ye-Android ebizwa ngokuba yiGadgetBridge ephethe yonke into efunekayo kwifowuni, njengolawulo lwesaziso, ulawulo lomculo kunye nokunye okuninzi.

I-ZSWatch ngoku ithi enye yee-smartwatches ezixhaswayo kwiGadgetbridge, ilandela i-API efanayo.

Kwicala le izixhobo zehardware ezenza Iprojekthi ikhankanya oku kulandelayo:

• Iimpawu zehardware kwiZSWatch v1
• nRF52833 BLE chip (u-blox ANNA-B402 imodyuli).
• 1,28″ 240×240 TFT IPS isikrini sesetyhula esinomlawuli weGC9A01.
• I-Accelerometer yokubala inyathelo, njl. (LIS2DS12TR).
• Ukusetyenziswa kwe-pulse oximetry kunye nesantya sentliziyo (MAX30101EFD).
• Imotor yeVibration ene-haptic controller ukunika ulawulo olungcono lokungcangcazela (DRV2603RUNT) .
• I-8MB isibane sangaphandle (MX25R6435FZNIL0).
• Itshaja yebhetri kunye nokujonga ibhetri (MAX1811ESA+ ithebhu, TLV840MAPL3).
• Amaqhosha ama-3 okukhangela (ngaphambili/elilandelayo/ngena)
• 220 mAh Li-Po ibhetri.
• Ikristale yeSapphire ukukhusela isikrini.

Kwaye inxalenye yeIimpawu eziphambili zesoftware kule projekthi kugqame oku kulandelayo:

• Ukusebenzisana ne-smartphone kunye nolawulo ngeGadgetBridge yesicelo se-Android.
• Ujongano lomzobo onokubonisa iwotshi, umhla, intlawulo yebhetri, uqikelelo lwemozulu, amanyathelo athathiweyo, inani lezaziso ezingafundwanga, kunye nesantya sentliziyo.
• Inkxaso yezaziso ezivelelayo.
• Imenyu eyandiswayo enesetingi.
• Ujongano lokukhetha isicelo. Kweenkqubo, kucetywa umququzeleli kunye newijethi yolawulo lokudlala umculo.
• I-pedometer edibeneyo kunye nomsebenzi wokubeka iliso kwizinga lentliziyo.
• Inkxaso yeBluetooth Direction Ukufumana iteknoloji ukumisela isalathiso isignali yeBluetooth, ikuvumela ukuba usebenzise iwotshi njengethegi elandelwa yiyo nayiphi na ibhodi ye-u-blox ye-AoA.

Ukususela kwinxalenye yezicwangciso zexesha elizayo zokuphuhliswa kweprojekthi kukhankanyiwe ukuba kucetywayo ukubandakanya isicelo sokubetha kwentliziyo, ukuhlaziya inkqubo yokubhanqa yeBluetooth kunye nohlengahlengiso lwecasing yegraphic ngendlela yesicelo sokutshintshwa.

Gqibela kwabo banomdla kuphuhliso lweprojekthi, kufuneka bazi ukuba oku kuhanjiswe phantsi kwelayisenisi ye-MIT kwaye banokubonisana nayo yonke into malunga nayo eli khonkco lilandelayo.
