Taw qhia

"NHL Light" yog rau cov kiv cua hockey uas xav ua raws lawv pab neeg, tab sis tsis tuaj yeem saib txhua qhov kev ua si. Nws yog qhov zoo tshaj plaws yog tias nws ua piv txwv lub hom phiaj nrog lub hockey hockey (kev cai rau koj pab neeg), thiab lub teeb.

Ntxiv rau lub suab hockey thiab lub teeb, "NHL Light", muaj cov duab uas muab tam sim no, lossis qhov kev ua si tsis ntev los no cov qhab nia, sijhawm ua si lossis sijhawm ntawm kev ua si tom ntej, thiab hnub tim thiab sijhawm tam sim no.

"NHL Lub Teeb" sau rau ntawm cov npe yooj yim ntawm cov khoom, uas yooj yim rau sib dhos cov khoom siv hluav taws xob, thiab cov cai uas muaj pub dawb.

Nta

1. Lub vev xaib raws kev teeb tsa rau xaiv koj pab neeg thiab wifi
2. Ua lub teeb thiab suab nrov thaum koj pab pawg sib tw (txawm tias thaum koj yog pab neeg nyob deb)
3. Plays suab tshaj tawm pib ntawm qhov kev ua si
4. Plays lub suab tshaj tawm qhov xaus ntawm qhov kev ua si
5. Muab sijhawm thiab hnub tim ntawm kev ua si tom ntej, yog tias tsis muaj kev ua si game.
6. Qhia tawm lub sijhawm tam sim no thiab sijhawm, yog tias kev ua si tseem tab tom ua.
7. Qhia hnub tim thiab sijhawm tam sim no.

Kauj Ruam 3: Kauj Ruam 3: Txheej Txheem Txheej Txheem Txheej Txheem Software

1. Npaj Raspberry Pi W.

   1. Rasberry pi yuav tsum tau khiav qhov tsis ntev los no ntawm Raspbian (lossis lwm yam Debian).
   2. Pom zoo kom ua raws cov lus qhia no:
   3. Nco ntsoov suav nrog wifi wpa_supplicant file.
   4. Muab cov ntaub ntawv ssh tso rau hauv sdcard kom tso cai ssh nkag mus.

2. Npaj cov software thib peb:

   1. Kuv tau siv cov txheej txheem no kom rub tag nrho cov cuab yeej xav tau thib peb, tab sis xav tias dawb los ua cov haujlwm no, thiab tshuaj xyuas kom paub tseeb tias tsis muaj cov kauj ruam ua tsis tiav.
   2. Rub tawm thiab khiav cov ntawv hauv qab no:

Nov yog kev rhuav tshem dab tsi ntawm cov ntawv teeb tsa rau teeb tsa lub operating system ua. Nws yog qhov zoo tshaj los khiav cov kab no ntawm tus kheej, yog li koj tuaj yeem saib rau qhov ua yuam kev.

Kauj Ruam 4: Kauj Ruam 4: Hloov kho JSON Configuration

Teeb koj cov ntaub ntawv teeb tsa JSON rau pab pawg koj nyiam, thiab lwm yam. Cov ntaub ntawv no nyob hauv /opt /nhl GO CAPITALS! config JSON cov ntaub ntawv

Lub software siv JSON cov ntaub ntawv los teeb tsa kho vajtse thiab pab pawg koj tab tom ua. Pab pawg tuaj yeem teeb tsa los ntawm lub vev xaib uas yuav ua haujlwm, tab sis kev teeb tsa kho vajtse xav tau teeb tsa tus kheej:

Nov yog kev piav qhia ntawm txhua tus nqi tau:

• myteam: qhov no yog 3 tsab ntawv ntawm pab pawg koj xav ua raws
• debug: Qhov muaj peev xwm ua tau yog 1 (tseeb) lossis 0 (cuav), thiab yuav tswj hwm kev txiav tawm ntau npaum li cas.

• cov zis: qhov no yog cov txheej txheem uas cov qhab nia/cov ntsiab lus yuav tsum tau qhia. Qhov tseem ceeb yog:

  • lcd: qhov no yog 2004 lcd
  • console: qhov no yuav sau tsuas yog rau lub davhlau ya nyob twg (rau kev ua kab hais kom ua)
  • oled: txhawb nqa rau SSD6404 oled zaub

• teeb: muaj ob hom teeb pom kev zoo

  • tswb: qhov no yuav tsav ib zaug GPIO rau kev qhib/tua lub transistor
  • multi-led: txhawb nqa ntau xim, lossis ntau leds
  • tsis muaj: tsis muaj lub teeb txuas
• amp: qhov no yog GPIO uas tsav lub transistor rau lub amp
