U-Mudita ukhululiwe nge-blog post esithathe isinyathelo sokukhulula ikhodi yomthombo ye ipulatifomu yeselula I-MuditaOS, esekelwe ohlelweni lokusebenza lwe-FreeRTOS ngesikhathi sangempela futhi elungiselelwe amadivayisi anezikrini ezakhiwe ngobuchwepheshe bephepha likagesi (i-e-ink).
Inkundla ekuqaleni yayiklanyelwe ukusetshenziswa kumafoni amancane anezibonisi ze-e-paper ezingasebenza ngaphandle kokushajwa kabusha ibhethri isikhathi eside.
I-kernel yesistimu yokusebenza ngesikhathi sangempela I-FreeRTOS isetshenziswa njengesisekelo, lapho kusebenza khona i-microcontroller ene-64 KB ye-RAM eyanele. Ukuze uthole ukugcinwa kwedatha, uhlelo lwefayela olubekezelela iphutha lubandakanya ama- littlefs, athuthukiswe inkampani ye-ARM yohlelo lokusebenza lwe-mbed OS.
Uhlelo luthobela i-HAL (Isendlalelo se-Hardware abstraction) kanye ne-VFS (I-Virtual File System), eyenza ukuqaliswa kokusekela kwamadivayisi amasha nezinye izinhlelo zamafayela kube lula. Ukuze uthole ukugcinwa kwedatha okusezingeni eliphezulu njengencwadi yamakheli namanothi, kusetshenziswa i-SQLite DBMS.
Ezicini ze-MuditaOS, singaqokomisa okulandelayo:
- Umsebenzisi obonakalayo olungiselelwe ngokukhethekile izibonisi ze-monochrome ngokusekelwe ephepheni le-elekthronikhi. Ukuba khona kwesikimu sombala "omnyama" ongasikhetha (izinhlamvu ezikhanyayo kungemuva elimnyama).
- Izindlela ezintathu zokusebenza: ungaxhunyiwe ku-inthanethi, ungaphazamisi futhi uxhumeke ku-inthanethi.
- Ibhuku lamakheli elinohlu loxhumana nabo abagunyaziwe.
- Isistimu yemiyalezo ephuma esihlahleni, izifanekiso, okusalungiswa, i-UTF8, nokusekelwa kwe-emoji.
- I-MP3, WAV ne-FLAC isidlali somculo esihambisanayo esiphatha amathegi e-ID3.
- Isethi ejwayelekile yezinhlelo zokusebenza: isibali, ithoshi, ikhalenda, iwashi le-alamu, amanothi, isiqophamazwi, nesofthiwe yokuzindla.
- Ukuba khona komphathi wohlelo lokusebenza ukuphatha umjikelezo wempilo wezinhlelo kudivayisi.
- Umlawuli wesistimu oqalisa ekuqaliseni kokuqala futhi aqalise isistimu ngemva kokunika amandla kudivayisi.
- Ingabhangqwa namahedfoni e-Bluetooth nezipikha ezisekela i-A2DP (Iphrofayili Yokusabalalisa Umsindo Ethuthukisiwe) kanye ne-HSP (Iphrofayili Yezifakwakhanda).
- Ingasetshenziswa kumafoni anama-SIM khadi amabili.
- Imodi yokulawula ukushaja okusheshayo kwe-USB-C.
- Ukusekela i-VoLTE (Izwi nge-LTE).
- Ikhono lokusebenza njengendawo yokufinyelela ukusabalalisa i-inthanethi kwamanye amadivaysi nge-USB.
- Ukwenziwa kwasendaweni kwesixhumi esibonakalayo sezilimi eziyi-12.
- Ukufinyelela ifayela nge-MTP (Media Transfer Protocol).
Ngesikhathi esifanayo, ikhodi ye uhlelo lokusebenza ledeskithophu Isikhungo se-Mudita, esihlinzeka ngemisebenzi yokuvumelanisa ibhuku lamakheli kanye nesihleli sekhalenda nohlelo olumile, faka izibuyekezo, landa umculo, finyelela idatha nemilayezo esuka kudeskithophu, dala izipele, thola ukwehluleka, futhi usebenzise ifoni njengezindawo zokufinyelela.
Uhlelo lubhalwa kusetshenziswa iplatifomu ye-Electron futhi luza emihlanganweni yeLinux (AppImage), macOS, kanye neWindows. Ngokuzayo, kuhlelwe ukuvula izinhlelo zokusebenza ze-Mudita Launcher (umsizi wedijithali yesikhulumi se-Android) kanye ne-Mudita Storage (isitoreji samafu nohlelo lokuthumela imiyalezo).
Kuze kube manje ukuphela kwefoni esekelwe ku-MuditaOS i-Mudita Pure, okuhlelwe ukuthi iqale ukuthunyelwa ngoNovemba 30.
Izindleko ezimenyezelwe zedivayisi ngu-$369 futhi ifoni inikwa amandla yi-microcontroller ye-ARM Cortex-M7 600MHz enememori engu-512KB TCM futhi ifakwe isikrini se-E-Ink esingu-2.84-intshi (isixazululo esingu-600 × 480 kanye nemithunzi engu-16 empunga), 64 MB SDRAM, 16 GB eMMC Flash. Isekela i-2G, 3G, 4G / LTE, Global LTE, UMTS / HSPA +, GSM / GPRS / EDGE, Bluetooth 4.2 ne-USB Type-C (ukufinyelela kwe-inthanethi ne-Wi-Fi ngo-opharetha weselula akutholakali, kodwa idivayisi ingasebenza njengemodemu ye-USB GSM), isisindo esingu-140 gr., Ilinganisa u-144x59x14,5 mm, ibhethri ye-lithium-ion eshintshwayo engu-1600 mAh ngokushajwa okugcwele emahoreni angu-3 futhi ngemva kokuyivula, isistimu iqala kumasekhondi angu-5.
Kulabo abathanda ikhodi ye-MuditaOS, kufanele bazi ukuthi ibhalwe ku-C/C ++ futhi ishicilelwe ngaphansi kwelayisensi ye-GPLv3. Ungathintana ne inothi kusixhumanisi esingezansi.
