2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24

Ib nrab vim yog kuv txoj kev txaus siab ua qee yam zoo li no, thiab ib nrab vim yog kuv qhov kev txaus siab hauv Codesys Kuv tau muaj nws nyob hauv kuv lub siab ib pliag tam sim no los sim thiab txuas txuas qhov txuas Network Network thib ob rau Raspberry Pi. Yog li thaum ua lwm txoj haujlwm kuv tau xav, nyeem, sib piv, npaj thiab yuav khoom kom kuv thaum kawg tuaj yeem ua ntej thiab tsim qee yam.

Yog - Kuv paub.. muaj qee qhov "tig -qhov tseem ceeb" npaj mus rau cov kab ke muaj nyob qhov twg yuav ua dab tsi zoo ib yam, tab sis tiag tiag tsis muaj leej twg txaus siab txaus los cais kuv ntawm kuv cov nyiaj.

Hauv qhov tseeb, kuv muaj qib qis ntawm kev paub thiab kev paub ntawm Raspberry Pi thiab Linux / Raspberry Pi IOS (Raspian) (Kuv ua tau zoo dua hauv Windows thiab Android ntiaj teb), tsis muaj kev paub tob txog Networking (Kuv tuaj yeem ua haujlwm tau zoo) thiab tsim cov tes hauj lwm, tab sis dhau ntawd kuv nyob ntawm kuv lub taub hau me ntsis), thiab kuv tsuas yog nyuam qhuav pib ua Circuit Boards. Kom paub meej, Kuv tsis yog tus programmer.

Thaum kawg kuv txiav txim siab txav mus rau tom ntej nrog lub tswv yim ntawm kev tsim ib yam dab tsi, thiab xaiv los siv WIZ820io / USR -ES1 tus qauv, uas yog raws li Wiznet - W5500 integrated Circuit. Cov qauv no tuaj yeem sib tham nrog Raspberry Pi (thiab lwm yam MCUs) siv tus qauv tsheb npav SPI. Ib qho ntxiv, nws tawm ntawm 3.3 VDC, yog li nws ua rau Xoom puas tsuaj rau kuv li Raspberry Pi.

Ntawm kev tsim cov phiaj xwm hluav taws xob, kuv tau xaiv los tsim nws hauv qhov tsim nyog "HAT" teeb tsa (cov duab thiab lub peev xwm), thiab ntxiv rau ntxiv cov phiaj xwm hluav taws xob rau "WIZ820io module Kuv kuj tau ntxiv qee qhov ntawm lwm yam khoom uas tsis siv hauv qhov no phiaj xwm sib tham, tab sis qhov kuv tuaj yeem thiab yuav siv rau lwm txoj haujlwm yav tom ntej.

Pawg thawj coj kuv tsim / tsim muaj cov khoom hauv qab no ntawm nws.

1 - Lub qhov (socket) los tuav Wiznet - WIZ820io - Ethernet chaw nres nkoj module (Kuv tau ua tus cai Eagle hneev taw rau qhov no).

2 - 30 mm - 5 VDC txias kiv cua rau Raspberry Pi CPU (Kuv tau ua tus cai Eagle hneev taw rau qhov no).

3 - A "CAT24C32" Memory Chip kom tswj tau HAT qhov yuav tsum tau ua (qhov no tseem tsis tau tsim los ntawm kuv) (Kuv tau ua tus cai Eagle Design Block rau qhov no).

4 - Mini MAX3232 - UART - TTL rau RS -232 Theem Hloov Chaw txuas nrog UART0 (Kuv tau ua tus cai Eagle hneev taw rau qhov no).

5 - Lub Liab LED (GPIO24), Lub Daj LED (GPIO23) thiab Lub Ntsuab LED (GPIO22) kom siv rau Kev Teeb Tsom Teeb - Python cov phiaj xwm ua haujlwm.

6 - Green LED (GPIO18) thiab Green LED (GPIO27) - rau kev ua haujlwm thiab ua haujlwm daws teeb meem.

7 - Tactile Hloov txuas nrog GPIO25 - rau kev ua haujlwm lub cev thiab daws teeb meem (Kuv tau ua tus cai Eagle Hneev taw rau qhov no). Nco tseg tias GPIO no tseem yuav siv nrog WIZ820io.

Yog li raws li kuv tau sau tseg yav dhau los, Cov Lus Qhia no tsuas yog cuam tshuam nrog Yam #1 ntawm cov npe no. Txhua lwm yam khoom uas kuv tau ntxiv rau ntawm lub rooj tsavxwm muaj lwm qhov laj thawj tsis cuam tshuam nrog qhov haujlwm Network Interface.

Khoom siv

Raspberry Pi - Kuv siv Raspberry Pi 3B qub. Tsis muaj dab tsi txhaum nrog qhov ntawd.. Kuv muaj qhov chaw nres nkoj HDMI tuag, yog li kuv siv nws "tsis muaj hau" siv TeamViewer nkag mus rau nws. Nws ua haujlwm. Kuv xav tias qhov feem ntau ntawm Raspberry Pi's yuav ua haujlwm nrog Cov Lus Qhia no uas lawv tuaj yeem ua haujlwm ntau dua tam sim no ntawm Raspberry Pi IOS (Raspian).

Ua ntej pib txhua qhov no, Kuv tau hloov kho qhov kev ua haujlwm:

sudo apt-tau hloov tshiab

sudo apt-tau hloov tshiab

WIZ820io / USR -ES1 - Cov ntaub ntawv rau qhov no muaj nyob online los ntawm OEM

PC Board - Kuv tau siv Autodesk Eagle los tsim PCB nrog, thiab tsim cov ntaub ntawv Gerber tsim nyog rau JLCPCB los tsim lub rooj tsav xwm nrog. Raws li tau sau tseg yav dhau los, Kuv kuj tau ntxiv "CAT24C32" Memory Chip kom tswj tau HAT qhov xav tau sib xws.

Kauj Ruam 1: Raspberry Pi 3b

Raws li rau Raspberry Pi, Kuv tau ua qhov haujlwm no siv tus qauv Raspberry Pi 3b, nrog rau qhov hloov tshiab kawg ntawm Raspberry Pi IOS (Raspian) uas kuv tuaj yeem rub tawm thiab teeb tsa.

Tsis muaj dab tsi tshwj xeeb nyob ntawd. Kuv tau yog tus tswv ntawd ob peb xyoos, thiab nws tau ua haujlwm zoo rau kuv (zoo - HDMI cov vis dis aus tso tawm yog li kuv thiaj yuam kom khiav tsis siv lub TeamViewer). Koj yuav tsum tsis tas yuav ua qhov no.

Kuv xav tias ib qho RPi yuav tsum tuaj yeem txuas rau WIZ820io / USR -ES1 - Wiznet W5500 thiab ua haujlwm no, nrog rau ntau lwm hom lag luam sib tw hauv tib lub khw (Beagle Bone, Orange, Tinker, thiab lwm yam) thiab siv qhov zoo sib xws qauv Linux raws OS.

Kuv muaj ZERO kev paub nrog ib qho ntawm cov ntawd. Kuv muaj kev paub me me nrog Raspberry - saib qhov twg tau txais kuv:)

Kauj Ruam 2: Sib cuam tshuam Wiznet WIZ820io Module rau Raspberry Pi GPIO Bus

Txheeb xyuas cov duab txuas.

Wiznet WIZ820io module muab ob kab ntawm 6 tus pin txhua tus los cuam tshuam rau.

Cov kab ntawv tau sau tias "J1 thiab" J2 "feem.

Cov Ntaub Ntawv Cov Ntaub Ntawv lawv muab muaj cov xim xim zoo nkauj heev ntawm txhua tus pin. Daim duab no txhais tau tias yog pab koj txuas cov pins no mus rau koj li Raspberry PI GPIO pins. Lawv zoo nkauj heev NAME rau NAME sib tw.

Raspberry Pi pinout nws tuaj yeem pom ntawm no: pinout.xyz

Kuv txuas cov pins raws li hauv qab no (saib daim duab txuas):

Tau kawg, txij li kuv tau ua lub rooj tsav xwm hauv Circuit tiag, txhua Pawg (GND) tau txuas ua ke. Tib yam mus nrog rau 3.3V tus pin - kuv lub rooj tsav xwm sib txuas nrog cov ua ke.

Qee qhov ceeb toom..

1st - J2 Pin #5 - RSTn - Kuv txuas qhov ntawd rau RPi GPIO #17 (Pin #11) - Qhov ntawd tau ceev faj. Kuv tsis ntseeg tias nws tau siv.

2nd - J1 Pin # 6 - INTn - Qhov ntawd txuas nrog GPIO25 (Pin # 22). Qhov no xav tau, txij li hauv Raspberry Pi IOS txheej txheem teeb tsa, peb yuav xa mus rau qhov no.

3rd - J1- Pin # 5 - SCNn - Qhov ntawd txuas nrog Raspberry Pi "CS0" (Pin # 24). Ua tau zoo uas muab cov qauv no rau qhov chaw nyob ntawm "Module 0" ntawm RPi SPI Bus. Ib zaug ntxiv, hauv Raspberry Pi IOS txheej txheem teeb tsa, peb yuav hais txog qhov no.

Kauj Ruam 3: Kuv Lub Rooj Tsav Xwm

Txuas nrog yog Eagle "Point to Point" schematic Kuv tau tsim thiab nrog uas kuv tsim cov ntaub ntawv Gerber.

Kuj txuas nrog yog cov duab yog "Circuit Board" Kuv tau ua tiav rau txoj haujlwm no.

Pawg thawj coj no yuav lees paub ntau tus Wiznet cov khoom sib txawv ntawm WIZ820io style.

Kauj Ruam 4: Raspberry Pi IOS (yav dhau los Raspian) Kev teeb tsa - Nkag mus rau hauv "khau raj" Folder

Rau Raspberry Pi kom "pom" qhov tshiab teeb tsa WIZ820io module ntawm nws lub tsheb npav SPI, IOS yuav tsum tau ua kom paub, yog li nws tuaj yeem cuam tshuam nrog nws thaum "BOOT Up".

Txhawm rau ua qhov no, peb yuav yooj yim ntxiv ob kab rau:../../boot/config.txt

Ua ntej.. Siv Terminal pane / window ==> ls

cd../boot, coj koj txoj hauv kev mus rau../boot thiab sau (ls) cov npe

Siv cov duab txuas.. Muaj koj yuav tsum nrhiav thiab lees paub tias muaj ob qhov nkag nkag - Kuv tau ncig lawv liab.

Ib qho yog cov ntaub ntawv npe: "config.txt"

Qhov thib ob yog daim nplaub tshev npe: "kev sib tshooj"

== == == ==

Thaum koj tau lees paub tias muaj ob qho ntawm cov ntawv no, koj tuaj yeem txuas ntxiv mus rau theem tom ntej

Kauj Ruam 5: Raspberry Pi IOS (yav dhau los Raspian) Kev teeb tsa - Nkag mus rau hauv "kev sib tshooj" Cov Npe

Hloov Cov Ntawv Teev Npe rau "kev sib tshooj" cov npe"

Hom: cd overlays

Tom qab ntaus tus "nkag" tus yuam sij, uas yuav coj koj mus rau "kev sib tshooj" nplaub tshev (saib cov duab txuas nrog).

Sau cov ntsiab lus ntawm phau ntawv teev npe.

Laj: ls

Tom qab ntaus tus "nkag" tus yuam sij, koj yuav tsum pom cov npe ntev ntawm cov ntsiab lus ntawm cov npe ntawd. Cov npe tej zaum yuav yog tus lej.

(saib cov duab txuas (2 ntawm)). Daim ntawv ceeb toom tias yuav luag tag nrho cov ntaub ntawv muaj npe txuas nrog: *.dtbo koj kuj tseem tuaj yeem pom ob peb lub npe nrog kev txuas ntxiv ntawm: *.dtb

Cov no yog TXHUA "Device Tree" overlay files

Koj yuav tsum tau lees paub tias muaj ob daim ntawv "overlay" (saib cov duab txuas nrog).

1st - cov ntaub ntawv npe: anyspi.dtbo (rau qhov no, koj yuav xav tau siv kab ntawv nyem rau ntawm sab xis ntawm lub qhov rais kom rov qab mus rau sab saud thiab pom cov ntawv sau ua piv txwv anyspi.dtbo).

2nd - cov ntaub ntawv npe w5500.dtbo

== == ==

Yog tias koj tuaj yeem lees paub tias ob qho ntawm cov ntaub ntawv no muaj, tom qab ntawd koj tau zoo thiab tuaj yeem rov qab mus rau../boot directory.

Hom: cd../ tom qab ntaus tus yuam sij ENTER, koj yuav tsum raug coj rov qab mus rau / phau ntawv teev npe.

Sau cov npe kom paub meej: hom: ls thiab ntaus ENTER qhov tseem ceeb

Kauj Ruam 6: Raspberry Pi IOS (yav dhau los Raspian) Kev teeb tsa - Kho Cov Ntaub Ntawv Npe: Config.txt

Hauv qhov../boot directory, tam sim no peb tuaj yeem ua haujlwm ob peb qhov kev kho me me rau cov ntaub ntawv npe: config.txt

Peb yuav xub hu rau "nano" tus kws kho mob ua "super user" (sudo)

sudo = 'superuser' cov

nano yog cov ntawv sau uas peb yuav siv

thiab raws li tau sau tseg, config.txt yog cov ntawv peb xav hloov.

Hom: sudo nano config.txt thiab ntaus ENTER.

Qhov no yuav coj tus kws kho mob, thiab tso saib cov ntsiab lus ntawm cov ntaub ntawv config.txt. Yog tias tus kws kho mob tsis qhib, lossis qhib qhov khoob, tom qab ntawd tawm (yog tias nyob hauv nano) thiab ob zaug xyuas koj cov ntawv sau.

Yog tias txhua yam mus tau zoo, koj yuav tsum pom qee yam zoo li hauv daim duab thib ob. "nano" yuav nthuav tawm "sab saum toj" heev ntawm cov ntawv. koj yuav tsum tau nqes mus rau hauv qab heev.

Hauv qab ntawm cov ntawv, ntxiv ob "dtoverlay nqe lus" hauv qab no:

dtoverlay = anyspi, spi0-0, dev = "w5500", ceev = 30000000dtoverlay = w5500

Ua ob zaug txheeb xyuas txhua qhov kev sau ntawv, thiab yog tias nws sib xws, nias ob lub yuam sij "Ctrl-x" kom tawm mus.. thiab teb kom tsim nyog kom txuag thiab tawm.

== == == ==

Ntawm qhov khau raj tom ntej (thiab rau txhua qhov boot-ups tom qab yog tias ob nqe lus tseem nyob ntawd) cov txheej txheem ua haujlwm tam sim no tseem yuav hu rau cov npe "anyspi" thiab cov npe "w5500".

Cov txheej txheem "anyspy" npaj cov txheej txheem ua haujlwm siv SPI0-0 lub npav (uas yog qhov uas yav dhau los peb txuas lub cev WIZ820io rau. #J1-6 rau RPi GIPO "CEO" (Pin #24).

Cov txheej txheem "w5500" qhia txog kev ua haujlwm yuav ua li cas nrog W5500 kev sib koom ua ke nyob hauv WIZ820io module. Nws tseem txhais kom siv RPi GPIO25 (Pin #22) ua INTn teeb liab. Rov nco txog ib zaug ntxiv uas peb yav dhau los tau ua qhov kev sib txuas no.

Cov ntaub ntawv zoo li no tuaj yeem pom hauv ntau cov ntaub ntawv, zoo li qhov piv txwv no pom ntawm GITHub.

== == ==

Lub sijhawm rov pib dua RPI, thiab ua kom txhua qhov no siv tau.

Kauj Ruam 7: Peb tau rov pib dua. Kuv vam tias koj luag ntxhi

Yog tias txhua yam mus tau zoo, koj li RPi yuav tsum tau rov pib dua ib txwm muaj. Luag.

Lub sijhawm los tshuaj xyuas yog tias IOS thauj khoom ob daim ntawv tshiab, thiab yog tias nws lees paub qhov txuas WIZ820io module.

Ib zaug ntxiv qhib lub qhov rai "Command".

Lub sijhawm no ntawm qhov hais kom sai, ntaus ifconfig (lossis siv qhov tshiab "ip" hais kom ua), thiab ntaus qhov Enter.

Tej zaum koj yuav tau txais cov lus teb ntev, yog li koj yuav tsum tau rov qab mus rau saum.

Rov qab rau saum, nrhiav ob ntu:

Ib lub npe hu ua eth0, thiab lub npe thib ob: eth1 - saib cov duab txuas nrog.

Hauv kuv qhov kab ke, eth0 yog Ethernet chaw nres nkoj ntawm RPI. eth1 yog WIZ820io Ethernet Port tshiab.

== == ==

Yog tias koj pom ob lub chaw nres nkoj, ces yog RPI. Daim ntawv ceeb toom hauv daim duab txuas, eth1 tau xa cov ntawv ntim, thiab tsis muaj qhov yuam kev.

Kuv tau sim qhov no los ntawm kev txuas lub xov tooj qub chaw nres nkoj, thiab siv qhov browser mus rau YouTube thiab lwm lub vev xaib.. Nws ua haujlwm. Kuv kuj tau "ping'd" nws los ntawm ob peb lub cuab yeej sib txawv thiab nws ua haujlwm.

== == ==

Yog tias koj tsis pom eth1 (lossis qee yam zoo sib xws) - tsis yog eth0 ntawm RPI3 lossis RPi4, tom qab ntawd sim rov qab mus thiab txheeb xyuas ob zaug tias cov config.txt raug kho kom raug thiab raug cawm. Ua kom paub tseeb tias ob qhov kev sib tshooj nyob hauv qhov chaw, thiab sau ntawv raug (tsis muaj cov tsiaj ntawv loj uas kuv tsis muaj - cov tsiaj ntawv tseem ceeb hauv cov kab ke no).

== == ==

Yog tias ob lub chaw nres nkoj nyob tam sim no, tej zaum yuav muaj kev teeb tsa me ntsis ntxiv los ua … nyob rau theem tom ntej ….

Kauj Ruam 8: Raspberry Pi IOS (yav dhau los Raspian) Kev teeb tsa - Teeb IP Chaw Nyob

Nov yog me ntsis ntawm kuv lub tsev log, yog li lub sijhawm no kuv tsis tuaj yeem muab kev qhia.

Tsuas yog paub tias muaj ntau lub vev xaib, YouTube cov vis dis aus, thiab cov ntawv xov xwm uas muab cov ntaub ntawv zoo li no.

tab sis.. koj yuav xav tshuaj xyuas thiab ua qee yam ntawm no.

1 - Ob zaug txheeb xyuas tus IP chaw nyob uas koj qhov chaw nres nkoj tshiab tam sim no muaj. nws puas tau muab los ntawm koj tus neeg rau zaub mov DHP, lossis nws puas yog tus IP qub - qee yam hauv thaj tsam ntawm: 169.254.xxx.yyy? Puas yog lwm yam ??

2- Koj puas xav tau Static (tsau) IP chaw nyob lossis Dynamic IP chaw nyob (muab los ntawm koj li DHCP server).

Txheeb xyuas qhov hloov / router uas koj RPI txuas nrog.. nws puas pom koj qhov chaw nres nkoj tshiab? nws puas tuaj yeem "Ping" nws? (nco ntsoov tshem tawm qhov qub chaw nres nkoj cable yog tias koj ua qhov no - txwv tsis pub RPi yuav dag koj).

Siv ifconfig (lossis tshiab dua "ip" hais kom ua) kom pom tias cov ntaub ntawv los thiab mus tab tom saib "ib txwm" (yog li tham) thiab tsis muaj tus lej yuam kev.

== == ==

Thaum kawg.. Kuv ntseeg tias nws yog w5500.dtbo muab MAC chaw nyob rau WIZ820io / W5500 module.. tab sis kuv tsis tuaj yeem hais meej yog tias qhov ntawd tshwm sim. Kuv tsis tuaj yeem pom cov ntsiab lus tam sim ntawd.

Rau kuv nws zoo li qhov sib txawv MAC chaw nyob tau muab rau txhua lub sijhawm nws khau raj. Kuv tus kheej tsis nyiam qhov ntawd, thiab yog li muaj qee yam uas tuaj yeem ua tiav los teeb tsa Mac Chaw Nyob (qhov program "macchanger" piv txwv lossis teeb tsa nws los ntawm ip / ifconfig cov lus txib). Yog tias ib tus ntawm koj pom "boot-up" / "crontab" daws rau qhov no, Kuv zoo siab tau hnov txog koj yuav ua li cas yog tias koj qhib rau kev sib qhia.

Koj tuaj yeem pom kuv hauv daim duab.. Thaum kuv saib-txog Mac Chaw Muag Khoom rau eth0 ==> b827eb, nws los ua Raspberry Pi Foundation. Tus neeg muag khoom rau eth1 ==> fa9770 los txog li tsis paub, yog li pom tseeb, nws tau tsim ntawm kuv Pi ntawm qee kis.

Kauj Ruam 9: Xaus

Ua tsaug rau kev tshuaj xyuas Cov Lus Qhia no.

Kuv kawm paub ua haujlwm me ntsis los ntawm txoj haujlwm me me no.

Puas yog koj muaj lus nug, lossis yuav txaus siab yuav ib qho ntawm cov laug cam uas kuv tau tsim (muaj neeg nyob lossis tsis), Kuv muaj qee qhov ntxiv uas yog muag thiab uas peb tuaj yeem tham txog.

Hauv txhua qhov xwm txheej, Kuv yaum koj kom tawm lus, qhia kho kom raug (yuam kev lossis cov txheej txheem lossis ??)

Feem ntau-qhov tseeb, yog tias koj ua qhov no rau koj tus kheej, Kuv yuav txaus siab heev kom pom cov duab ntawm qhov koj tau daws nws li cas, thiab koj qhov txiaj ntsig kawg / lub hom phiaj.

Ua tsaug.

PS: Ua tsaug rau tus phooj ywg no rau kev qhia thiab tswv yim.
