Cov neeg pabcuam serial port feem ntau siv hauv Linux

Hauv qab lub tshuab ua haujlwm Linux, kev siv kev sib txuas lus ntawm qhov chaw nres nkoj serial yog ib qho ntawm cov haujlwm uas siv ntau. Txawm hais tias nws yog kev debugging ntawm lub cuab yeej lossis kev xa cov ntaub ntawv, nws yog ib qho tseem ceeb heev uas yuav tsum paub txog cov cuab yeej pabcuam serial port hauv Linux. Tsab xov xwm no yuav qhia txog ntau yam cuab yeej pabcuam serial port uas siv ntau hauv Linux, nrog rau yuav ua li cas rau nruab thiab teeb tsa lawv.

Cov Ntsiab Lus

• 1. Cov neeg pabcuam serial port feem ntau siv hauv Linux
• 2. Cov khoom siv chaw nres nkoj serial Linux
• 3. Kev teeb tsa cov cuab yeej kuaj serial port

1. Cov neeg pabcuam serial port feem ntau siv hauv Linux

Lub Linux system muab ntau yam cuab yeej rau kev sib txuas lus serial port, uas muab faib ua ob hom: command line thiab graphical interface.
(1). Minicom raws li kab hais kom ua: minicom yog ib lub cuab yeej sib txuas lus raws li ntawv nyeem. Nws me me thiab muaj zog, tsim nyog rau cov neeg siv uas nyiam ua haujlwm kab hais kom ua.
(2). Cov duab interface putty (Ceeb toom: xshell tsis muaj Linux version): Txawm hais tias putty feem ntau siv rau hauv Windows ib puag ncig, nws kuj muaj ib qho version rau Linux. Putty muab ib qho graphical interface, ua rau kev ua haujlwm yooj yim dua.
(3). Cutecom uas siv Qt: cutecom yog ib qho chaw pabcuam serial port uas siv Qt library. Nws muab ib lub graphical interface thiab tseem txhawb kev nkag mus sai rau qhov configuration ntawm cov khoom siv serial port.

2. Cov khoom siv chaw nres nkoj serial Linux

Tsis zoo li Windows systems, Linux systems lees paub cov chaw nres nkoj serial ua cov ntaub ntawv khoom siv, feem ntau nyob hauv daim nplaub tshev /dev/. Muaj ob hom khoom siv serial tseem ceeb ntawm Linux systems:
(1). Cov chaw nres nkoj serial ib txwm muaj: xws li ttyS0, ttyS1, thiab lwm yam, sawv cev rau cov khoom siv serial ib txwm muaj. Koj tuaj yeem saib cov ntaub ntawv ntawm cov khoom siv no los ntawm dmesg | grep ttys command.
(2). USB rau cov chaw nres nkoj serial: xws li ttyUSB0, ttyUSB1, thiab lwm yam, cov no yog cov khoom siv serial hloov pauv los ntawm USB. Siv cov lus txib dmesg | grep ttyUSB los saib cov ntaub ntawv ntawm cov khoom siv no.

3. Kev teeb tsa cov cuab yeej kuaj serial port

Kev Teeb tsa Cutecom

1. Ua ntej koj yuav tsum tau nruab Cutecom, koj yuav tsum hloov kho cov ntaub ntawv pob khoom los ntawm kev nkag mus rau hauv sudo apt-tau hloov tshiab los ntawm lub davhlau ya nyob twg.
2. Cov lus txib kom nruab Cutecom yog sudo apt-tau nruab cutecomRau cov kev teeb tsa teb thiab cov chaw ruaj khov, siv a ntsiav tshuaj ruaj khov nrog Windows 11 tuaj yeem muaj txiaj ntsig zoo rau kev nqa mus los thiab kev ua haujlwm ntev.

Kev Teeb tsa thiab Kev Teeb tsa Minicom

1. Nruab Minicom los ntawm cov lus txib hauv qab no: sudo apt-tau nruab minicom.
2. Txhawm rau teeb tsa Minicom, nkag mus sudo minicom -s kom nkag mus rau qhov configuration interface, qhov twg koj tuaj yeem teeb tsa cov kev teeb tsa xws li lub npe ntawm cov ntaub ntawv ntawm lub serial port device. Tom qab ua tiav cov kev teeb tsa, txuag thiab tawm.
3. Thaum siv Minicom, koj tuaj yeem pib nws nrog cov lus txib sudo minicom -c rau, qhov twg -c rau parameter ua rau muaj xim tso tawm.
4. Txhawm rau tawm ntawm Minicom, nias ctrl+x thiab tom qab ntawd xaiv "yog."
   Yog xav tau cov haujlwm suav lej uas ruaj khov dua, xav txog kev siv ib qho Kev lag luam PC nrog GPU los yog ib qho lub computer rackmount ruaj khov.

Kev Teeb tsa thiab Siv Putty

1. Nruab Putty nrog cov lus txib sib xws (cov lus txib tshwj xeeb nyob ntawm koj qhov kev faib tawm Linux).
2. Thaum teeb tsa Putty, qhia tus lej chaw nres nkoj serial thiab baud rate ntawm kev sib txuas, thiab tom qab ntawd nyem "Qhib" hauv qhov kev xaiv "Serial" kom pib kev sib txuas. Rau cov chaw teeb tsa kev lag luam uas xav tau qhov chaw txuag tau, a 1U khib PC tej zaum yuav yog qhov kev xaiv zoo tshaj plaws. Tsis tas li ntawd, Kev lag luam PC Advantech muaj cov kev xaiv txhim khu kev qha rau kev siv tshuab hauv kev lag luam.

Los ntawm cov kauj ruam saum toj no, koj tuaj yeem nruab thiab teeb tsa cov cuab yeej pabcuam serial port hauv Linux system los pab txhawb kev sib txuas lus thiab kev debugging ntawm cov khoom siv serial port. Cov cuab yeej no muaj lawv tus kheej cov yam ntxwv, thiab cov neeg siv tuaj yeem xaiv cov cuab yeej tsim nyog raws li lawv nyiam thiab xav tau. Rau kev siv computer uas yooj yim thiab ruaj khov, tshawb nrhiav cov laptops ruaj khov rau muag kuj muaj txiaj ntsig zoo.
