2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31

DMX IO Platform Module yog 4-channel DMX transceiver. Hauv kev tau txais nws tuaj yeem tswj tau txog plaub txoj kab ntawm TTL tam sim no qis (3.3v, piv txwv li, rau servos thiab LEDs me me) lossis siab-tam sim no (12v, piv txwv li, teeb, xa tawm, solenoids, stepper motor, thiab lwm yam) tso tawm. Hauv hom kev xa, nws tuaj yeem xa cov lus txib rau tag nrho DMX ntug (512 raws). Txhua XLR-3 txuas txuas tso cai rau tus qauv ua tus txais lossis xa tawm (tus tswv) node hauv DMX network thiab 9-txoj haujlwm DIP hloov tso cai rau chaw nyob teeb tsa yam tsis hloov pauv firmware. RS-485 kev tsim kho vajtse tso cai rau hloov software ntawm RX thiab TX hom uas tso cai rau cov kws tshaj lij los sim ua haujlwm DMX txais cov haujlwm nrog rau cov ntawv thov txuas mus rau-DMX.

DMX yog dab tsi?

DMX yog cov txheej txheem txheej txheem uas ua haujlwm hla RS-485 kho vajtse txuas. Nws tau xub tsim los tswj cov teeb (Chauvet muaj pawg txias DMX teeb), tab sis nws kuj tseem siv los tswj cov kev pabcuam, LED's, stepper motors, txuas, thiab lwm yam khoom siv (Zoo li DMX Skeleton). Nws yog ib qho yooj yim-rau-siv, muaj zog raws tu qauv uas tso cai rau 1, 500 Feet + cable khiav siv cable pheej yig. Lub DMX network muaj 1 tus tswv cuab, thiab 1 lossis ntau dua cov cuab yeej qhev. 512 txoj kev tswj hwm muaj thiab muaj ntau yam khoom siv qhev siv ntau dua ib qho channel (piv txwv li, lub teeb yuav siv 1 channel rau yias, lwm qhov rau qaij). Txhua txoj hauv kev tuaj yeem txhawb 256 qhov ua tau zoo, txawm hais tias qee cov cuab yeej qhev yuav ua ke 2 txoj hauv kev rau 65, 535 qhov tseem ceeb. Cov txiaj ntsig channel tuaj yeem hloov pauv txog 44 zaug hauv ib pliag, lossis 44Hz.

Txog Cov Qauv no

Koj tuaj yeem ntxiv DMX IO Module rau Propeller Platform, tus tiv thaiv kab mob, lossis txawm tias yog lub khob cij. Kuv yuav tham txog kev siv nws nrog Parallax Propeller lossis Arduino thaum kawg ntawm cov lus qhia no. DMX IO module tau tsim los ntawm Jon Williams thiab tau ntawv tso cai raws li MIT License. Nws tshuaj xyuas DMX (thiab tus qauv no) hauv nws Kaum Ib Hlis Nuts n 'Volts kem, uas koj tuaj yeem nyeem ntawm no (pdf). Koj tuaj yeem rub tawm cov ntawv tsim lossis yuav cov khoom lossis PCB liab qab los ntawm Gadget Gangster. Pre-assembled modules kuj muaj. Lub sijhawm ua haujlwm yog li 45 feeb. Ua kom sov koj cov hlau txuas thiab mus rau theem tom ntej!

Kauj Ruam 24: Siv DMX

DMX yog qhov yooj yim siv:

Rau Propeller

SAWV DAWS

Jon Williams 'Kaum Ib Hlis Spin Zone tsab xov xwm muab ntau yam ntxaws txog DMX thiab nws tsim cov khoom li cas. Nws kuj tau sau ib qho khoom siv yooj yim (jm_dmxin) uas yuav yooj yim nyeem DMX qhov tseem ceeb. Nrog koj cov lej lej, koj tsuas yog xav tau ntxiv lub tsev qiv ntawv; obj dmx: "jm_dmxin" Thaum koj xav tau qhib lub dmx xyuas, pub lub ntsiab dmx.init (24, 16) '24 = tau txais tus pin, 26 = kev ua haujlwm LED kom tau txais tus nqi ntawm cov channel, nws tsis tuaj yeem yooj yim dua; dmx.read (chan) Nrog tus nqi dmx, koj tuaj yeem ua txhua yam koj xav tau - tso saib qee yam ntawm TV saib, tig lub teeb, ua qee qhov pwm rau ib channel, thiab lwm yam. Thaum koj ua tiav nyeem DMX qhov tseem ceeb, koj tuaj yeem free cog nrog; dmx.finalizeJon tau ua tiav qhov txias dua nrog RGB teeb pom kev zoo siv Bit Angle Modulation hauv nws tsab xov xwm.

Xa

Yog tias koj tus DMX IO module yog tus tswv xa xov, tsis txhob hnov qab xaub ntawm lub jumper shunts rau ob leeg dhia. Txog software, muaj DMX xa khoom hauv Propeller Obex uas ua rau yooj yim DMX tso zis. Nov yog qhov piv txwv ntawm yuav siv nws li cas; Ua ntej ntxiv cov khoom mus rau ntu ntu ntawm koj txoj cai tig; obj dmxout: "DMXout" los pib nws; dira [25]: = outa [25]: = 1 'nqa TX pab kom highdmxout.start (26)' pib dmxoutsending dmx qhov tseem ceeb tsis tuaj yeem yooj yim dua - tsuas yog; dmxout. Write (2, 255) 'channel = 2, tus nqi = 255
