Qhov chaw nres nkoj infrared yog siv los tsim kev sib txuas lus ntawm ob qho khoom siv los ntawm kev siv hluav taws xob nyob ntawm qhov chaw deb. Xws li cov cuab yeej tso cai, piv txwv, siv cov chaw taws teeb tswj kom tswj hwm lub computer thaum saib cov yeeb yaj kiab lossis mloog cov nkauj. Qhov chaw nres nkoj infrared tuaj yeem tau yuav hauv cov khw tshwj xeeb lossis ua koj tus kheej hauv tsev.
Cov Lus Qhia
Kauj ruam 1
Siv cov pob qub qub hauv computer ua cov chaw nres nkoj me me. Txhawm rau ua qhov no, koj xav tau tus nas, hauv cov xov hlau txhawm rau txuas rau lub khoos phis tawm muaj plaub lub xov tooj: RTS, Rx, Tx thiab GND. Xaws cov xov hlau los txiav txim lawv lub npe. Lo nplaum lub khawm txuas rau ntawm daim yas.
Kauj ruam 2
Muag lub infrared LED thiab photodiode choj, thiab tseem coj 2-7 kOhm resistor: qhov siab dua qhov ua hauj, qhov loj dua qhov hluav taws xob ntawm IR qhov chaw nres nkoj yuav. Muag lub infrared LED rau Tx hlau, tom qab txuas hauv cov kab nrog cov tsis kam uas tseem txuas rau hauv av, uas yuav mus tib seem rau LED. Qhov Circuit Court no txuas nrog rau cov xaim Rx hlau thiab soldered rau cov txuas txuas 1 thiab 3 ntawm photodiode choj, tom qab ntawd RTS hlau txuas nrog qhov nruab nrab txuas.
Kauj ruam 3
Nruab WinLirc software ntawm koj tus kheej lub khoos phis tawm, uas ua haujlwm nrog IR ports. Khiav daim ntawv thov. Cov lus tshaj tawm tias qhov kev teeb tsa tsis tau zoo thiab koj yuav tsum tau kho ntxiv.
Kauj ruam 4
Txuas lub infrared chaw nres nkoj mus rau lub computer thiab tshawb xyuas qhov chaw nres nkoj twg nws txuas nrog los ntawm cov ntawv qhia zaub mov "Ntaus Tus Thawj Tswj". Qhib IR software. Qhia kom meej tus lej chaw nres nkoj hauv "Port" hauv daim teb, tawm ntawm "Speed" hauv daim teb tsis hloov. Txij li IR IR tau txuas rau Rx hlau, qhia kom meej RX cov cuab yeej hauv "Tau txais hom", thiab TX hauv "Transmitter nqis" teb.
Kauj ruam 5
Tom qab nkag mus rau hauv qhov tsis, nias "Raw Codes", nqa cov chaw taws teeb tswj xyuas kom tau txais thiab nias lub khawm ntawm nws. Yog tias qhov tshwm sim, nws txhais tau tias qhov sib txuas yog lawm. Yog tias tsis yog, kos seb tus soldering puas muaj tseeb. Qhib cov ntawv qhia "Kawm" los qhia qhov kev zov me nyuam kom paub txog cov chaw taws teeb tswj hwm ntawm chaw nres nkoj infrared. Teeb rau qhov yuav tsum tau ua thiab txuag lub chaw ua haujlwm.
