*** Tsis txhob rub qhov kev qhia no, tsuas yog nyem rau kauj ruam tom ntej yog OK. ***
Kauj Ruam 1: Cov Xeem thiab Cov Vuam
Koj tuaj yeem pom cov cim/daim ntawv lo ntawm PCB tiag qhia qhov twg mus rau qhov twg, thiab qhov kev taw qhia yuav tsum yog. yog tias koj xav tau kev siv ntau ntxiv ntawm txoj hauv kev tso cov khoom, ntawm no yog thawj daim duab
Muaj 3 qhov chaw smd, uas tau siv ua ntej xa khoom, lwm qhov koj yuav tsum tau muab nws txuas nrog hlau thiab qee qhov sib txuas rau lub leds, vim tias cov pins coj los nyob ze ib leeg, koj zoo dua muaj qee qhov ntws
1. Siv cov leds ua ntej VFD raj, qhov ntev tshaj plaws coj tus pin nkag mus rau hauv lub duab plaub los ntawm qhov.
2. Qhov "fais fab" txuas nrog ob txoj hauv kev xav tau txuas/luv
3. MCU (U17) muaj qhov program hauv nws, nws yuav ua haujlwm thaum fais fab tuag.
4. U9 thiab 5B16 qhov chaw raug tshem tawm thiab tsis tas yuav siv tshuaj yaj yeeb raws li qhia hauv daim duab.
5. Txiav 1-10mm qhov ntev tsis sib xws ntawm VFD raj tus pin yuav pab yooj yim ntxig rau tus pin qhov.
6. Cov ntu 1N5819 thiab 1N4007 zoo ib yam tab sis qhov sib txawv hauv qhov chaw sib txawv.
7. Tus pin ntev tshaj plaws ntawm tus coj mus rau hauv lub qhov rooj.
8. Lub 4 tus pin header tsis suav nrog thiab tsis xav tau cov laug, lawv tsis siv.
Kauj ruam 2: Ua ntej Power Up… Txheeb Xyuas
-Koj xav tau lub zog 5V1A, 5V0.5A tsis ua haujlwm. 5V2A yog maxium.
-Txheeb nrog daim duab qhia saum toj no yuav pab tau yooj yim dua.
-Cov cim "lub zog" ntawm PCB Kuv ua nws txuas nrog raws li daim duab zaum kawg.
-Qhov ntu 1N5819 thiab 1N4007 zoo ib yam tab sis sib dhos hauv qhov chaw sib txawv.
-RP1 txog RP6 muaj qhov dawb, xav tau ua kom haum rau qhov sib npaug ntawm qhov sib luag
Kauj Ruam 3: Cov Chaw Taws Teeb
Txhua lub khawm ua haujlwm
Roj teeb yuav tsis suav nrog vim huab cua xa khoom
hloov tshiab:
5 hloov YYMMDD MMDDYY DDMMYY
6 hloov Celsius/Fahrenheit
7 hloov 12/24 Teev
Ntawm lub tswb teeb tsa hom, los ntawm txhaj rau 200+ khawm, qhib/tua lub tswb
- Tswb tawm
CA tswb nyob
Kauj Ruam 4: Cov Haujlwm
Qee yam yuav pab kom paub zoo dua ntawm lub moos
--Cov ds39b20 lossis ds18b20 yog qhov ntsuas kub, koj tuaj yeem muab nws txuas nrog kab txuas txuas ntawm lub moos kom tsis txhob muaj PCB thiab coj lub teeb sov.
- Cov leds tsis tuaj yeem yaj nrog cov cua sov ntau dua 350 ° C lossis 662 ° F
Kauj ruam 5: Tsis muaj Case?
Kuv tswj kom muab lub moos nyob ze rau tom qab dawb, coj lub teeb ci rau ntawm phab ntsa tsim kom pom kev zoo, yog li nws tsis tsim nyog rau rooj plaub yog tias koj tau muab tso rau tom qab dawb.
Kauj Ruam 6: Teeb Meem Q&A
Kev coj ua haujlwm, kev ua haujlwm nyob deb, tab sis lub raj tsis pom lossis tsis pom cov ntawv
Txheeb xyuas lub tshuab hluav taws xob loj nyob rau sab laug hauv qab, nws yuav tsum muaj 24-28 Voltage ntawm lub zog, lossis nws yog teeb meem ntawm U11 thiab L1, U11 hloov pauv 5volt rau 2x volt. Yuav tsum tau kuaj xyuas ob zaug yog tias lawv nyob hauv qhov raug, lossis pom ib feem twg muaj cua sov ntau dhau.
Yog tias ib yam saum toj no zoo, sim tshem MCU thiab lub zog ntawm lub moos, lub raj yuav tsum tso ib tsab ntawv 8.
Ib qho ntawm VFD raj tsis ua haujlwm, lossis ib nrab ua haujlwm
Sim hloov ULN2803APG thiab SN74HC00N qab nws, los ntawm kev sib pauv nrog lwm lub raj
Kuj pom yog tias muaj qhov txuas txuas sab hauv lub raj
