2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Nov yog thawj qhov sib txawv ntawm MCU/Qhov sib xyaw ua ke hauv ASSIMILATE SENSOR HUBS: tus tswv uas khaws cov ntaub ntawv pov tseg los ntawm I2C ASSIMILATE SENSORS qhev.

Qhov kev tsim no siv Wemos D1 Mini, tshaj tawm cov ntaub ntawv pov tseg los ntawm ASSIMILATE SENSORS mus rau MQTT server. Nws muab tsheb npav 3V3 I2C rau lub ntsuas cua. Txoj kev tsheb nqaj hlau 5V tseem tau muab tab sis tsis muaj lub logic qib hloov pauv rau 5V I2C thiab nws yuav tsis ua haujlwm raws li xav tau. Qhov no yuav raug xa mus rau yav tom ntej lub ntsej muag-teeb tus ntxhais-pawg hloov pauv rau qhov uas tau nthuav tawm ntawm no.

Yog tias koj tsis tau ua li ntawd, lub plhaub txheej sab nrauv yuav tsum tau muab sib dhos.

Kauj Ruam 1: Cov Ntaub Ntawv thiab Cov Cuab Yeej

ICOS10 (IDC) Plhaub Nqi Khoom Siv

10. 4G x 15mm Khawm taub hau tus kheej tapping screws (2)
11. 4G x 6mm tus kheej tapping countersunk screws (~ 20)

Kauj Ruam 2: Kev Npaj MCU

Hauv qhov kev tsim no peb tab tom siv Wemos D1 Mini. Yog tias koj tau ua yav dhau los D1M WIFI BLOCK, koj tuaj yeem siv qhov ntawd rau cov khoom siv kho vajtse hloov pauv. Yog tias tsis yog, yam tsawg kawg liab qab ua raws seem tom ntej.

Muag lub taub hau PINS ntawm MCU (siv tus lej PIN JIG)

Yog tias koj tsis tuaj yeem luam tus lej PIN JIG tsuas yog ua raws cov lus qhia thiab tsim kho: qhov siab (offset) ntawm tus lej PIN JIG yog 6.5mm.

1. Luam/tau tus PIN JIG los ntawm nplooj ntawv no.
2. Pub cov kab taub hau hla hauv qab ntawm lub rooj tsavxwm (TX sab xis-sab laug) thiab rau hauv cov laug cam.
3. Nias tus pin nqes mus rau qhov tiaj tiaj.
4. Nias lub rooj tsavxwm nqes mus rau lub jig.
5. Ua tus kav 4 lub ces kaum pins.
6. Reheat thiab rov ua haujlwm pawg thawj coj/tus pin yog xav tau (pawg thawj coj lossis tus pin tsis sib dhos lossis cov kav dej).
7. Solder tus so ntawm tus pin.

UPLOADING LUB FIRMWARE

GIST rau txoj cai nyob ntawm no (5 cov ntaub ntawv) thiab zip yog nyob ntawm no. Cov lus qhia rau kev siv Arduino IDE rau kev suav sau/xa tawm cov cai nyob ntawm no.

Txhawm rau siv cov cai nrog tsuas yog kev hloov kho me me, peb tab tom siv Joël Gähwiler's shiftr.io ua MQTT broker: nws muaj tus as khauj qhua - yog li thov khaws lub sijhawm ntawm kev tshaj tawm feeb sib nrug. Nws muab kev pom pom ntawm lub hauv paus thiab cov ncauj lus, nrog rau kev txo qis rau cov ntaub ntawv.

Thaum cov cai tau raug thauj mus rau Arduino IDE:

1. Hloov kho tus nqi ntawm _wifi_ssid nrog koj li WiFi SSID.
2. Hloov kho tus nqi ntawm _wifi_password nrog koj tus yuam sij WiFi.
3. Hloov kho tus nqi ntawm _mqtt_clientid nrog qhov koj xav paub Tus Neeg Siv Khoom (tsis xav tau koom nrog).
4. Hloov kho tus nqi ntawm _mqtt_root_topic nrog qhov chaw nyob hierarchy ntawm lub cuab yeej qhov chaw.
5. Compile thiab upload.

Kauj Ruam 3: Kev Npaj Tsev MCU

MCU Vaj Tsev nthuav tawm lub taub hau rau D1 Mini los ntsaws rau hauv thiab lub taub hau rau tus ntxhais-laug cam uas sib txuas lus nrog Lub Qhov (lub ntsuas cua thiab tus ua yeeb yam) Circuit.

HOUSING HEADERS

Qhov no yog ua raws D1 Mini Protoboard, thiab sib cais:

1. Pins rau D1M BLOCK/D1 Mini txuas rau.
2. Kev Ncaj Ncees ncaj qha ntawm 2 kab ntawm kev sib cuag los ntawm D1M BLOCK/D1 Mini. Cov no tsuas yog muaj rau kev yooj yim thaum ua qauv. Nws tau cia siab tias tus ntxhais-laug cam yuav thaiv txhua qhov nkag mus rau cov ntawv no.
3. 4 Kev tawg ntawm cov pins tshwj xeeb uas siv los ntawm tus ntxhais-laug cam. Kuv txiav txim siab tsuas yog rhuav tshem I2C cov pins tshwj xeeb tab sis kuv twb muaj qhov siv-siv rau lwm tus pin (qis-qis pw tsaug zog hloov pauv), yog li kuv tsoo RST, A0 thiab qee qhov lwm yam pins tsuas yog hauv rooj plaub.

Txhawm rau ntxiv D1M Cov Neeg Tiv Thaiv rau HOUSING HEADER:

1. Saib tus muag khoom siv Lub SOCKET JIG video.
2. Pub cov kab taub hau hla hauv qab ntawm lub rooj tsavxwm (TX sab laug-sab laug rau sab saum toj).
3. Pub jig hla lub taub hau yas thiab qib ob sab.
4. Tig jig thiab sib dhos dua thiab nias lub taub hau ncaj qha mus rau qhov tiaj tiaj.
5. Nias lub rooj tsavxwm nqes mus rau lub jig.
6. Solder 4 lub kaum tus pin uas siv cov laug me me (tsuas yog ua ntu zus ntawm tus pin).
7. Reheat thiab rov ua haujlwm pawg thawj coj/tus pin yog xav tau (pawg thawj coj lossis tus pin tsis sib dhos lossis cov kav dej).
8. Solder tus so ntawm tus pin.
9. Tshem tawm jig.
10. Txiav pins tawm saum cov laug.

Txhawm rau ntxiv Daughter-board Breakouts:

1. Txiav 4 tawm 9P Poj niam lub taub hau.
2. Nyob rau sab saum toj, ntxig 9P Lub Taub Hau raws li qhia, thiab muab tshuaj txhuam tso rau hauv qab.

Txhawm rau ntxiv Direct Breakouts:

1. Txiav 2 tawm 8P Poj niam lub taub hau.
2. Nyob rau sab saum toj, ntxig rau 8P Lub Taub Hau raws li qhia, thiab muab tshuaj txhuam tso rau hauv qab.

Txhawm rau txuas lub taub hau, hauv qab nrog TX tus pin taw qhia nce:

1. Lw thiab solder los ntawm RST tus pin hla 4 tus pin.
2. Lw thiab solder los ntawm tus pin A0 hla 4 tus pin.
3. Lw thiab solder los ntawm D1 tus pin hla 4 tus pin.
4. Lw thiab solder los ntawm D2 tus pin hla 4 tus pin.
5. Lw thiab solder los ntawm D6 tus pin hla 4 tus pin.
6. Lw thiab solder los ntawm D7 tus pin hla 4 tus pin.
7. Lw thiab solder los ntawm GND tus pin hla 4 tus pin.
8. Kab thiab kab laug sab los ntawm 5V tus pin hla 4 tus pin.
9. Kab thiab kab laug sab los ntawm 3V3 tus pin nqes 45 ° hla 4 tus pin.

TSEV KAWM NTAWV TSHAJ PLAWS

Lub HOUSING HEADERS tau txuas rau MCU HOUSING thiab qhov no tau txuas rau BASE PLATE.

1. Nrog rau sab ntev ntawm HOUSING HEADERS taw tes rau lub qhov, ntxig D1M KEV TIV THAIV rau hauv qhov qhib hauv MCU HOUSING thiab thawb dej ntws tawm.
2. Ntxig MCU mus rau MCU CONTACTS thaum sib txuas kom ntseeg tau tias ua kom raug.
3. Muab lub taub hau TEEB sab saum toj ntawm cov khoom sib dhos ua ke thiab txuas nrog 2 ntawm 4G x 16mm ntsia hlau.
4. Muab cov khoom sib dhos ua ke nrog lub qhov taw qhia rau sab luv thiab sau nrog 4G x 6mm ntsia hlau.

Kauj Ruam 4: Tsim 3V3 I2C Daughter-board

Qhov no muab IDC Header rau SOCKETS CIRCUIT thiab txuas rau MCU, ntxiv kev rub tawm ntawm kab I2C. Qhov no tau muab los ua tus ntxhais-pawg thawj coj kom yog tias koj xav tau 5V kev hloov pauv qib kev xav, koj tsuas tuaj yeem sib pauv lub rooj tsavxwm no nrog ib qho uas muab txhua txoj haujlwm xav tau. Cov kab AUX thiab GND tau tawg tawm rau cov kev cai tshwj xeeb (zoo li cov chaw qis qis thaum lub sijhawm pw tsaug zog). Cov txheej txheem tau piav qhia los ntawm sab hauv thiab sab nraud: ntawm lub rooj tsavxwm xaiv ib sab uas zoo li siv sab hauv; qhov tseem ceeb yog IDC Header yuav tsum nyob ntawm ntug taw tes tawm.

1. Nyob sab hauv, ntxig rau 2P 90 ° Txiv Neej Lub Npe (1), 3P 90 ° Txiv Neej Lub Taub Hau (2), thiab muab tshuaj txhuam tso rau sab nraud.
2. Ntawm sab hauv, ntxig rau 1P Txiv Neej Header (3), 2P Txiv Neej Headers (4), thiab muab tshuaj txhuam tso rau sab nraud.
3. Sab nraud, ntxig IDC Header (5), thiab muab tshuaj txhuam tso rau sab hauv.
4. Ntawm sab hauv, taug qab cov xaim dub los ntawm BLACK1 rau BLACK2 thiab cov laug.
5. Ntawm sab hauv, taug qab cov xaim dub los ntawm BLACK3 rau BLACK4 thiab cov laug.
