Cov cim LCD cov ntxaij vab tshaus uas nthuav qhia cov ntaub ntawv yog cov ntaub ntawv nrov. Lawv ib txwm tswj hwm los ntawm qhov chaw nres nkoj sib luag, lub hnab ntim chaw nres nkoj, lossis hnab ev USB (ntau dua). Cov lus qhia no qhia peb qhib qhov chaw ethernet network LCD hnab ev khoom. LCD tswj cov haujlwm zoo li LCD Smartie (Windows) thiab LCDproc (Linux) tuaj yeem siv ethernet LCD lub hnab ev ib yam li cov lej thiab USB yam, tab sis dhau ntawm lub network. Nws muaj txiaj ntsig zoo rau kev saib xyuas ib qho system los ntawm txhua qhov chaw ntawm lub network: tso LCDs qhov uas koj tsis tuaj yeem tso lub computer, lossis saib xyuas lub khoos phis tawj uas nyuaj mus cuag. Peb siv nws los txheeb cov ntaub ntawv xov xwm, RSS txau, playlists, email tshiab, Folding@Tsev stats, thiab lwm yam kom deb ntawm lub PC. Cov vis dis aus no qhia nws hauv kev nqis tes ua, LCD tau txais cov ntaub ntawv los ntawm LCD Smartie hla lub ethernet network. Hauv kab lus no peb qhia koj yuav ua li cas thiaj li rov qab tau LCD Smartie tso tawm los ntawm cov chaw nres nkoj txuas mus rau lub hnab ev LCD. Nov yog ntu 2 ntawm txoj haujlwm network LCD hnab ev khoom, nyeem ntu 1 ntawm no. Pom Studio muaj ob peb qhov sib dhos #twatch ethernet LCD ntim rau $ 45, suav nrog kev xa khoom thoob ntiaj teb. Saib kab ntawv no nrog thawj qhov kev teeb tsa ntawm Dangerous Prototypes blog. Concept cov ntsiab lus Lub lim tiam dhau los peb tau tshaj tawm Twitter scrolling nta ntawm lub hnab ev LCD. Nws kuj tseem muaj TCP server ntawm chaw nres nkoj 1337 uas lees txais Matrix Orbital formatted commands. Matrix Orbital hnab ev khoom muaj kev txhawb nqa dav, LCD Smartie thiab LCDproc yog qhib qhov kev xaiv. Cov kev tswj hwm feem ntau tsav LCDs los ntawm cov chaw nres nkoj sib luag thiab ob peb kab ntawv lossis USB hnab ev khoom. Network TCP cov zis tseem tsis tau muaj kev xaiv. Peb siv tus choj txhawm rau xa mus rau LCD Smartie qhov chaw nres nkoj txuas mus rau lub network LCD hnab ev khoom.

Kauj ruam 1: Kho vajtse thiab Firmware

Peb tau qhia PIC 18F67J60 ethernet LCD lub hnab ev khoom kho vajtse lub lim tiam dhau los. Txheeb tawm tsab xov xwm dhau los kom ntxaws ntxaws txog kev kho vajtse rub tawm cov ntaub ntawv tshiab tshaj plaws los ntawm qhov haujlwm Google Code nplooj ntawv thiab tsim koj tus kheej. Koj tseem tuaj yeem yuav cov cuab yeej sib sau ua ke rau $ 30 ($ 45 w/LCD), suav nrog kev xa khoom thoob ntiaj teb, kom txog rau lub Cuaj Hlis 23, 2009. FirmwareA TCP server mloog ntawm chaw nres nkoj 1337 rau Matrix Orbital-style LCD txib. Cov khoos phis tawj tuaj yeem xa cov lus txib mus rau qhov chaw nres nkoj no ib yam li nws yog lub hnab ntim hauv LCD. Peb ua raws Matrix Orbital lub hnab ev ntawv vim tias feem ntau cov cim LCD tswj cov kev pabcuam txhawb nws. Real-sijhawm Twitter txau scroll ntawm LCD kom txog thaum TCP server tau txais cov lus txib uas tso tus cursor ntawm txoj haujlwm 0. Thaum tau txais cov lus txib no, Twitter hloov tshiab kawg thiab TCP neeg rau zaub mov siv tag nrho kev tswj hwm ntawm LCD. Peb ntxiv ob qhov tsis yog-tus qauv txib rau Matrix Orbital teeb. 153 qhia tus IP chaw nyob raws li muab los ntawm DCHP, thiab 154 rov pib dua Twitter hom. Tsis muaj cov neeg siv tam sim no siv lawv.

Kauj ruam 2: Choj Serial Port mus rau TCP Server

LCD cov phiaj xwm tswj hwm feem ntau ua haujlwm nrog qhov chaw nres nkoj sib luag, ntu, thiab USB LCDs. Network TCP tseem tsis tau muaj kev xaiv. Nqe lus no qhia yuav ua li cas xa mus tom ntej LCD Smartie cov ntaub ntawv chaw nres nkoj mus rau ethernet LCD lub hnab ev. Peb siv Windows, yog li peb tau rub tawm cov dawb software ntawm Virtual Serial Port Emulator, qhov chaw nres nkoj yooj yim hloov pauv. Yog tias koj muaj Linux lossis OSX cov lus qhia, thov tso lawv rau hauv cov lus lossis lub rooj sab laj.

Kauj Ruam 3: Tsim Virtual Serial Port

Ua ntej, peb teeb tsa lub chaw nres nkoj sib txuas virtual. Qhov kev tswj hwm LCD (LCD Smartie) yuav txuas rau ib qho ntawm cov chaw nres nkoj no, lwm qhov txuas rau TCP tus neeg siv khoom peb teeb tsa tom qab. Nyem txuas ntxiv. Xaiv tus lej rau txhua qhov chaw nres nkoj. Tus lej chaw nres nkoj yuav tsum pub dawb ntawm koj lub cev. Peb teeb nws rau COM7 thiab COM8. Peb tau txheeb xyuas tus nqi baud, txawm hais tias nws yuav tsis tsim nyog. Nyem OK.

Kauj Ruam 4: Tsim TCP Client

Tom ntej no, tsim TCP tus neeg siv los txuas qhov chaw nres nkoj mus rau lub hnab ev khoom TCP server. Nyem txuas ntxiv. Qhov chaw nyob TCP server zoo ib yam li tus IP chaw nyob ntawm LCD ntawm lub zog-rau. Tus neeg rau zaub mov mloog ntawm chaw nres nkoj 1337. Uncheck DTR/RTS nyob ntawm qhov xwm txheej sib txuas, peb tsis xav tau kev tswj ntws. Peb txuas TCP tus neeg siv khoom rau COM 8, thiab teeb tsa nws rau 115200bps, 8/N/1. Nyem OK. Qhov chaw nres nkoj mus rau TCP server choj yuav tsum ua haujlwm. TcpClient xwm txheej yuav nyeem OK yog lub ethernet LCD lub hnab ev tau teb ntawm IP chaw nyob

Kauj Ruam 5: Kho Khoos Phis Tawm Tswj LCD

Kauj ruam kawg yog teeb tsa koj li kev tswj hwm LCD kom siv lub network txuas. Kho nws kom siv qhov kawg pub dawb ntawm cov chaw nres nkoj sib txuas virtual (COM7 hauv peb qhov piv txwv). Teem qhov nrawm kom phim qhov chaw teeb tsa virtual (115200bps). Koj yuav tsum tau rov pib dua los siv qhov chaw tshiab. Kho lub khoos phis tawj LCD kom pom RSS txau, ceeb toom email, sijhawm ping server, PC stats, thiab lwm yam; qee qhov muaj plugins ntxiv thiab. Cov txiaj ntsig yuav dhau los ntawm qhov chaw nres nkoj virtual mus rau lub network hauv zej zog, thiab tso tawm ntawm LCD. Cov vis dis aus no qhia nws hauv kev nqis tes ua, LCD tau txais cov ntaub ntawv tso tawm ntawm lub network ethernet.

Kauj Ruam 6: Xaus & Yuav Tau Qhov Twg

LCD Smartie thiab LCDproc tau qhib qhov chaw, yog li leej twg tuaj yeem ntxiv qee qhov kev txhim kho rau ethernet LCD hnab ev khoom. Nws yuav zoo yog tias lawv tuaj yeem tswj hwm lub hnab ev LCD ncaj qha hla TCP, tsis muaj tus choj.

Feem ntau cov kev tswj hwm LCD tuaj yeem ua rau cov nyees khawm. Ob lub nyees khawm tuaj yeem txuas nrog lub hnab ntawv lub programing header, lossis PCB tshiab tuaj yeem ua nrog ntau khawm txuas. Matrix Orbital cov lus txib teeb tsa txhawb kev sib piv software, uas yuav pab tau zoo rau cov nyob deb ntawm LCDs. Qhov no tej zaum yuav ua tiav los ntawm kev siv mem tes-dav tes taws los piav rau tus lej hloov pauv. Ethernet LCD lub hnab ev khoom tuaj yeem hloov kho dua hauv lub network, saib ntu 1 rau cov lus qhia. Peb yuav txuas ntxiv txhim kho firmware thiab ntxiv cov yam ntxwv tshiab. Txheeb xyuas txoj haujlwm Google Code nplooj ntawv thiab lub rooj sab laj rau qhov rub tawm zaum kawg. Tau txais ib Seeed Studio muaj ob peb qhov sib dhos #twatch ethernet LCD ntim rau $ 45, suav nrog kev xa khoom thoob ntiaj teb. Tau lawv thaum lawv kawg vim tias peb yuav tsis ua sai sai.
