2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Kab lus no yog kev taug qab ntawm kuv yav dhau los, tsab xov xwm muaj txiaj ntsig zoo txog kev tsim lub chaw tshaj xov xwm ntau yam, raws li thaum xub thawj ntawm Raspberry PI nrov heev tab sis tom qab ntawd, vim tsis muaj HEVC, H.265 thiab HDMI 2.2 ua raws, nws tau hloov mus rau Hardkernel's Odroid C2:

www.instructables.com/id/Advanced-Multimed…

Hauv tsab xov xwm dhau los, kuv tau sim npog tag nrho cov kauj ruam xav tau, pib los ntawm kev siv tshuab, hluav taws xob thiab thaum kawg SW uas xav tau kom tuaj yeem siv nws ntawm nws lub peev xwm tag nrho.

Raws li koj paub, kev hloov pauv hauv ntiaj teb no yog nrawm heev, thiab cov ntaub ntawv uas raug thiab hloov tshiab tuaj yeem dhau mus sai heev. Software feem ntau cuam tshuam, tab sis kuj HW cov laug cam tau tsim sai heev.

Nrog tso tawm SBC muaj zog tshaj plaws raws li lub sijhawm sau ntawv, Odroid N2 tau dhau los ua neeg nyiam ntawm Kodi (Kodi = Qhov zoo tshaj plaws qhib qhov chaw tshaj tawm xov xwm), tshwj xeeb tshaj yog pab pawg CoreELEC tau khaws nws thaum ntxov thiab muab kev txhawb nqa ua ntej pawg thawj coj tseem tau tshaj tawm rau pej xeem coob. Raws li kuv xav tau kov nrog lub ntiaj teb uas tau hloov pauv tas li, kuv tau xaj nws sai thiab ua rau muaj kev xav tsis thoob, txawm hais tias cov duab CoreELEC uas twb muaj lawm tseem nyob hauv "sim" theem, yuav luag txhua yam ua haujlwm ntawm lub npov.

Dab tsi txawv ntawm Odroid C2? Ntau heev:

• nws muaj 4k thiab HDR txhawb nqa, uas C2 tsis muaj
• USB 3.0 vs USB 2.0 chaw nres nkoj. Vim qhov no, nws zoo dua los tuav ntau lub USB TV tuners, dua li C2
• 4 GB RAM vs 2GB
• muaj zog dua CPU (nws yog tsim raws li Amlogic S922 CPU tshiab) vs Amlogic S905, muaj peev xwm khiav cov plugins uas xav tau kev nkag mus thiab yuav tsum siv SW rendering (Netflix, piv txwv) ntawm kev daws teeb meem HD, piv rau 720p, uas cov khoom siv yav dhau los ua kabl
• muaj qis zog hom
• muaj niaj hnub 4.xx kernel piv rau qhov qub heev 3.14.x uas yog ib qho ntawm qhov tsis zoo ntawm C2. Vim qhov no, nws tau sib xws nrog kho vajtse niaj hnub, zoo li USB tuners, game controllers, thiab lwm yam.

Kauj Ruam 1: Teeb Khoom Siv Hluav Taws Xob thiab Hluav Taws Xob

Raws li koj tau pom hauv kuv tsab xov xwm dhau los, txhawm rau kom muaj lub chaw tshaj xov xwm uas zoo nkaus li lub tsev tsim ua ib qho, Kuv tau siv lub qhov rooj qub ntawm STB qub los tuav cov khoom sab hauv. Txawm li cas los xij, dhau sijhawm kuv tau ua ntau yam kev hloov pauv rau kev teeb tsa thiab lub thawv ntawv tau dhau los ua tawg.

Nrog lub rooj tsav xwm tshiab no, kuv tau los xaus tias nws zoo dua los siv lub thawv ntawv tshiab.

Raws li ib daim duab qhia ntau dua 1000 lub ntiaj teb, kuv tau suav qee cov duab uas tau thaij thaum kuv tau muab txhua yam ua ke. Cov kauj ruam yog cov hauv qab no:

• Hauv qab ntawm Odroid N2 nta 4 qhov. Kuv tau siv qee qhov chaw yas nrog cov ntsia hlau nyob rau thaum kawg txhawm rau txhim kho nws mus rau hauv qab ntawm lub thawv yas. Nws yog qhov tseem ceeb kom ze li sai tau rau ntawm lub vaj huam sib luag pem hauv ntej, vim nws muaj IR tus txais uas tuaj yeem muaj txiaj ntsig ntawm qee kis, txawm tias kuv tab tom siv usb raws li qwerty remote (hom Airmouse)
• Tom qab ntawd, Kuv tau laum lub qhov rau hauv qab qhov twg 4 tuners (2 sundtek DVB-S2, 1 DVB-C/T2 los ntawm Dvbsky, T330) thiab Xbox ib tuner (kuj rau DVB-C)

• Lub ethernet txuas yog me ntsis ntawm overkill, tab sis kuv tuaj yeem pom tsis muaj dab tsi ntxiv uas tau yooj yim mountable (ncig lub qhov ntau dua li ib lub duab plaub):

• HDMI cable tau tsim los ntawm aliexpress. Yeej nws tuaj yeem yog txhua yam, tsuav nws muaj qee yam muaj peev xwm txuas nws mus rau tom qab vaj huam sib luag:

  www.aliexpress.com/item/Newest-30cm-50cm-6 …

• Lub Hwj Chim: Tsis zoo li Raspberry Pi, lossis Odroid C2, Odroid N2 tau muab los ntawm 12V hloov chaw 5V thiab muaj cov tswj hwm hluav taws xob nyob rau hauv kom muab 5V xav tau rau USB thiab lwm yam khoom siv. Kuv tsis pom lub zog siab tshaj plaws nws tuaj yeem ua tau, tab sis kuv pom tsis muaj teeb meem ua kom lub zog 4 tuners thiab VFD zaub module. Ntawm 40 tus pin header, koj muaj 5 tus pin rau 5V tso zis thiab tseem 3.3V, yog xav tau.
• Fais fab thiab xwm txheej LED: Rau 12V thiab 5V lub zog, Kuv tau siv 2 LEDs (ib qho yog UV LED, lwm qhov ib txwm ntsuab ib txwm). Nco ntsoov tias koj yuav tsum txwv qhov tam sim no, txwv tsis pub koj yuav ua rau LED thiab/lossis lub hwj chim puas. Kuv tau siv 1.2K resistors hauv koob, tab sis raws li hom kev teeb pom kev zoo uas koj xav tau, koj tuaj yeem siv qhov me me, tab sis nco ntsoov xam tias qhov siab tshaj tam sim no yuav tsum tsis pub tshaj 20mA.

• VFD: Kuv tau rov siv tib VFD zaub uas ib qho siv hauv kuv tsab xov xwm dhau los. Nws muaj lub hnab ev i2c, uas tau ntim rau hauv lub thawv dawb uas pom hauv ib qho ntawm cov duab. Koj tuaj yeem txuas nws mus rau i2c chaw nres nkoj ntawm Odroid N2, zoo ib yam li nws tau txuas nrog C2 lossis raspberry pi: 5V (tus pin 2 lossis 4), GND (tus pin 6), SDA (tus pin 3) thiab SCL (pin 5). Saib GPIO header layout ntawm Hardkernel tus vev xaib raug cai:

• Rau VFD thiab 2 xwm txheej LEDs, kuv yuav tsum txiav lub vaj huam sib luag pem hauv ntej. Lub thaiv uas kuv xaiv tso cai kom muaj 2 lub vaj huam sib luag pem hauv ntej. Kuv tau siv cov yas qub los tuav tag nrho cov khoom, thiab nyob rau hauv pem hauv ntej ntawm nws kuv tau siv iav, uas kuv tau txiav nws kom muaj qhov loj ib yam li yas ib ntawm ntawm cov khw hauv ib cheeb tsam uas ua li ntawd yam.

Kauj ruam 2: Teeb Software

Qhov no yog qhov txawv me ntsis dua li nws tau piav qhia yav dhau los hauv kab lus txuas thaum pib ntawm cov lus qhia no.

Txog Raspberry PI peb tau siv OSMC cov duab uas tau nthuav tawm tag nrho linux OS uas tso cai rau peb teeb tsa kuj tsim ib puag ncig kom muaj SW qhov tseeb tsim los ntawm cov peev txheej ntau dua li siv ib qho uas tuaj hauv cov chaw cia khoom.

Hmoov tsis zoo, thaum lub sijhawm sau tsab ntawv no, tsis muaj cov duab zoo li no rau Odroid C2, tsis yog N2 tshiab uas muaj tag nrho linux system thiab Kodi tau ua haujlwm zoo rau nws. Tam sim no, kev txhawb nqa zoo tshaj plaws yog ua los ntawm pab pawg CoreELEC, uas yog rab rawg los ntawm LibreELEC. Cov duab no tsuas yog nyeem nkaus xwb thiab Kodi tau teeb tsa mus rau qhov cais cais, hu ua /cia.

Vim li no, cov kab ke muaj zog tiv thaiv lub zog poob ntau dua thiab nyuaj rau tawg, tab sis kuj muaj qee qhov kev txwv: ib tus yuav tsum ua raws li binary SW tau tsim thiab muab los ntawm cov chaw khaws cia lossis tsis raug cai.

Tab sis txawm li ntawd los, ib tus tuaj yeem pom qhov hloov kho tshiab ntawm SW pacakges uas peb xav tau: tvheadend, oscam, lcdproc thiab ntau yam ntxiv rau tsos, nyob tv thiab xov tooj cua.

Ua thawj kauj ruam ua ntej, ua ntej txawm tias txhim kho ib yam dab tsi, daim duab yuav tsum tau hlawv mus rau SD daim npav (lossis EMMC) thiab muab tso rau hauv qhov zoo li qub.

Cov duab ntsuas rau N2 tuaj yeem rub tawm los ntawm no:

discourse.coreelec.org/t/odroid-n2-test-bu…

Tsis txhob ntshai tias nws yog daim duab sim! Nws ua haujlwm zoo kawg nkaus, thiab txawm tias muaj qee qhov teeb meem me me, nws yog qhov tsim nyog rau kev siv txhua hnub. Hlawv cov duab nrog balena ethcer:

www.balena.io/etcher/

thiab yog tias koj tau ua txhua yam sau, tom qab muab daim npav tso rau hauv lub qhov, nws yuav tsum khau raj kom zoo.

Txhawm rau teeb tsa SW cov kev pabcuam (tvheadend, oscam, lcdproc) siv CoreElec qhov chaw cia, Cov Haujlwm thiab Cov Haujlwm Pabcuam.

Txhawm rau teeb tsa tus txheej txheem tas, thov xa mus rau kab lus yav dhau los uas kuv tau sim ua kom nthuav dav txhua qhov.

Kauj Ruam 3: Xaus

Lub Odroid N2 yog pawg thawj coj saib xyuas zoo tshaj plaws uas muaj los yuav ntawm lub sijhawm no. Vero 4k+ yog cov khoom lag luam zoo heev, yog tias koj tsis nyiam tsim koj tus kheej, tom qab ntawd nws yog qhov kev xaiv zoo dua, txawm tias nws muaj thiab qub CPU (S905d). Nws tuaj yeem lis 4K thiab HDR ib yam nkaus, txawm li cas los nws tsis muaj zog txaus los ua hauv SW Netflix ntawm 1080p.

Yog tias nrawm yog qhov tseem ceeb rau koj, tom qab ntawd N2 yog qhov kev xaiv zoo dua yam tsis muaj kev poob siab.

Tsis tas li, CoreELEC tau ua txoj haujlwm zoo hauv kev txhawb nqa lub rooj tsav xwm no txij thaum pib thiab kuv tsuas tuaj yeem ua tsaug rau cov neeg koom nrog hauv qhov no.
