Kauj Ruam 5: Ua Circuit Court

Hauv cov duab saum toj no koj tuaj yeem pom cov txheej txheem ntawm cov ntawv luam tawm, nco ntsoov thaum koj ua cov no koj tsis luv dab tsi. Kuv xaiv tso T-cobbler, DRV8825 thiab HX711 ntawm poj niam lub taub hau yog li koj tuaj yeem yooj yim pauv lawv yog tias qhov no yuav tsum tsim nyog tab sis koj tsis tas yuav ua qhov no.

Kauj Ruam 6: HX711

Txhawm rau kom tau txais kev ntsuas ntawm lub xov tooj ntawm tes koj yuav tsum siv lub ntsuas qhov hnyav. Kuv siv HX711.

Kev sib txuas rau HX711:

• E+: liab hlau.
• E-: xaim dub.
• A+: xaim dawb.
• A-: ntsuab xaim.
• VCC: 5 V.
• SCK: GPIO 22.
• NTUJ: GPIO23.
• GND: NCO.

Tom qab koj tau txuas txhua yam, koj yuav tsum ntsuas qhov ntsuas ua ntej. Siv chav HX711 thiab tom qab ntawd cov cai hauv qab no:

hx = HX711 (23, 24) hx.set_reading_format ("LSB", "MSB") #hx.set_reference_unit (327) -> qhov no yuav tsum tau hais tawm hx.reset () hx.tare () val = hx.get_weight (5) pw tsaug zog (0.5) hx.power_down () hx.power_up () print (val)

Tam sim no cia tus lej khiav thiab tso qee yam ntawm qhov ntsuas. Xyuas kom koj paub qhov hnyav ntawm nws. Tos kom txog thaum koj zoo li 20 qhov txiaj ntsig thiab tom qab ntawd coj qhov nruab nrab ntawm nws. Tom qab ntawd koj faib tus lej no nrog qhov hnyav ntawm cov khoom koj siv. Tam sim no sau tus lej ntawd mus rau hx.set_reference_unit (tus lej) thiab tsis pom zoo nws. Kuaj nws tawm los ntawm kev muab cov khoom sib txawv ntawm qhov ntsuas.

Kauj Ruam 7: Stepper Motor

Pom tseeb peb xav tau qee cov khoom siv hluav taws xob los ua kom tag nrho cov haujlwm ua haujlwm. Txhawm rau tswj lub stepper lub cev peb xav tau tus tsav tsheb stepper, Kuv xaiv DRV8825.

Kev Sib Txuas rau DRV8825:

• VMOT: +12V (los ntawm DC-DC-hloov pauv).
• GND: GND (los ntawm DC-DC-hloov pauv).

Nco ntsoov tso lub capacitor nruab nrab ntawm ob.

• 2B: liab stepper hlau.
• 2A: xiav stepper hlau.
• 1B: dub stepper hlau.
• 1A: ntsuab stepper hlau.
• FAULT: koj tuaj yeem tso qhov tsis xav tau tab sis tseem tuaj yeem dai nws mus rau 5V.
• GND: GDN (los ntawm Raspberry PI (RPi)).
• ENABLE: tsis xav tau xaim.
• MS1-MS2-MS3: tsis xav tau xaim.
• RESET - SLEEP: txuas rau ib leeg thiab tom qab ntawd rau 3, 3V.
• KAUJ RUAM: GPIO20.
• PIB: GPIO21.

Ua ntej koj txuas txhua yam, tsuas yog txuas VMOT+GND, GND rau Rpi, RESET-SLEEP thiab STEP-DIR. Peb thawj zaug yuav tsum teeb tsa Vref rau tus tsav tsheb. Vref yuav tsum yog ib nrab ntawm qhov tam sim no stepper lub cev muaj zog xav tau. Rau lub cav no nws nyob ib puag ncig 600mV, ntsuas qhov hluav taws xob thiab cov ntsia hlau me me thiab tig nws kom txog thaum nws nyob ib puag ncig 600mV. Tom qab qhov no koj tuaj yeem txuas lwm cov xov hlau.

Txhawm rau thawb cov zaub mov los ntawm cov chaw tso dej mus rau qhov chaw pub mis koj yuav xav tau lub cav no. Rau cov tib neeg uas tsis muaj kev nkag mus rau 3D -tshuab luam ntawv koj ib txwm tuaj yeem siv 3D hub, zoo li qhov no -> HUB

Kauj Ruam 9: Txhim Kho MySQL

Txhawm rau khaws cov ntaub ntawv los ntawm cov kab ke muaj cov ntaub ntawv khaws cia rau hauv. Txhawm rau cia cov ntaub ntawv ua haujlwm peb xub tau teeb tsa MySQL ntawm RPi.

Ntaus cov lus txib hauv qab no hauv koj qhov kev sib txuas Putty:

sudo apt hloov tshiab

sudo apt install -y python3-mysqldb mariadb-server uwsgi nginx uwsgi-plugin-python3

Kuaj yog tias koj MariaDB ua haujlwm nrog:

sudo systemctl xwm txheej mysql

Tom qab qhov no peb yuav tsim ob peb tus neeg siv rau hauv peb cov database nrog cov lus txib hauv qab no:

Tsim tus neeg siv 'project-admin'@'localhost' IDENTIFIED BY 'adminpassword';

Tsim tus neeg siv 'project-web'@'localhost' IDENTIFIED BY 'webpassword';

Tsim qhov project DATABASE;

ZOO TSHAJ PLAWS NTAWV QHOV TSEEB.* Rau 'project-admin'@'localhost' NROG QHOV ZOO TSHAJ PLAWS;

GRANT SELECT, INSERT, Hloov tshiab, Rho tawm ntawm qhov project.* TO 'project-web'@'localhost';

Hloov tshiab mysql.user SET Super_Priv = 'Y' WHERE user = 'project-web' THIAB host = '%';

NTSEEG NTAWV QHOV TSEEB;

Tam sim no cov ntaub ntawv muaj nyob peb tuaj yeem sau cov ntaub ntawv nrog cov ntxhuav uas tsim nyog thiab txheej txheem khaws cia.

Thawj hom:

sudo -i ua

thiab tom qab ntawd:

mariadb

tom qab qhov no, theej cov cai hauv Projectdb.sql dhau los nws rau hauv mariadb.

Yog tias qhov no ua haujlwm ces koj ua tib yam rau lwm peb.sql cov ntaub ntawv thiab koj xaus nrog:

NTSEEG NTAWV QHOV TSEEB;

Yog tias txhua yam mus zoo koj cov ntaub ntawv tam sim no npaj mus!

PS: Yog tias qee yam tsis ua haujlwm, nco ntsoov … Google yog koj tus phooj ywg;-)!

Kauj ruam 10: Txhim Kho Txoj Cai
