2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:29

IOT123 BRICKS yog chav DIY modular uas tuaj yeem sib xyaw nrog lwm IOT123 BRICKS, txhawm rau ntxiv kev ua haujlwm rau ntawm qhov chaw lossis hnav tau. Lawv tau ua raws li lub xwmfab nti, ob-tog protoboards nrog sib cuam tshuam los ntawm qhov.

Ib tug xov tooj ntawm cov BRICKS no yuav tsum yog nyob ntawm ntau lub node (Master MCUs - ESP8266 lossis ATTINY84) ntawm qhov chaw. MCU tsis xav tau kev paub ua ntej txog lub hom phiaj ntsuas lossis software xav tau. Nws ntsuas rau I2C cov nodes tom qab ntawv thov cov khoom pov tseg (cov ntaub ntawv sensor) los ntawm txhua tus qhev. Cov BRICKs muab 5.0V, 3.3V thiab lwm txoj kab AUX uas tuaj yeem tsim kho tau.

Qhov I2C HEARTBEAT BRICK no qhia tias tus qhev ATTINY tseem muaj txoj sia nyob, tseem yog I2C kev mus los, thiab muaj ib lub cuab yeej:

STATUS ("NYOB")

PB1 (dawb) qhia txog ATTINY kev noj qab haus huv.

PB3 (daj) toggles nrog I2C thov los ntawm tus tswv.

PB4 (txiv kab ntxwv) toggles nrog I2C tau txais los ntawm tus tswv.

Qhov dhau los ntawm qhov uas nyob ib sab ntawm ATTINY85 tau tso tseg tsis siv, txhawm rau ua kom tus pogo tus programmer thaum DIP8 tau muab muag rau PCB. Ib qho kev tsis txaus ntseeg ntxiv, ntim BRICKS hauv lub tog raj kheej me uas txuas rau hauv D1M WIFI BLOCK hub, tso tus nqi rau MQTT server, tab tom tsim.

Kauj Ruam 1: Cov Ntaub Ntawv thiab Cov Cuab Yeej

Muaj Daim Ntawv Teev Npe Tag Nrho ntawm Cov Khoom thiab Sourcing.

Kauj Ruam 2: Npaj ATTINY85

NCO TSEG: Yog tias xav kom muaj Crouton kev koom ua ke, thov siv lub tsev qiv ntawv los ntawm no, thiab siv tus piv txwv teeb tsa "attiny_heartbeat"

AttinyCore los ntawm Tus Thawj Saib Xyuas Boards xav tau. Hlawv bootloader "EEPROM khaws cia", "8mHZ Internal" (txhua qhov teeb tsa pom saum toj no).

Qhov chaws khaws cia tuaj yeem pom ntawm no.

ZIP ntawm lub tsev qiv ntawv tuaj yeem pom ntawm no.

Cov lus qhia rau "Ntshuam ZIP Library" ntawm no.

Thaum lub tsev qiv ntawv raug teeb tsa koj tuaj yeem qhib qhov piv txwv "attiny_heartbeat".

Txhawm rau rub cov firmware rau ATTINY85, koj yuav pom cov ntsiab lus ntxiv hauv cov lus qhia no:
