BONISA USETYENZISO
Ukusebenzisa kunye neRaspberry Pi, kufuneka ufake umqhubi
- Bhala umfanekiso weRaspberry Pi OS kwikhadi leTF nguRaspberry Pi Imager onokukhutshelwa kwiRaspberry Pi esemthethweni webindawo.
- Faka ikhadi le-TF kwibhodi yeRaspberry Pi. I-LCD iya kubonisa emva kokuqalisa, kwaye emva koko ungene kwi-terminal ye-Raspberry Pi, (Kusenokufuneka uqhagamshele ibhodi yezitshixo kunye ne-HDMI LCD ku-Pi yokuhlohla umqhubi, okanye ungene ukude nge-SSH)
- Emva koko vula i-terminal ye-Raspberry Pi ukufaka umqhubi.
git clone https://github.com/waveshare/LCD-show.git-cdLCD-show/
I-Raspberry Pi kufuneka iqhagamshelwe kwinethiwekhi kuyo yonke inkqubo
Isikrini siya kusebenza emva kokuqalisa kwakhona.
Amanqaku:
- Ukwenza uphuculo lwe-apt-fumana kuya kubangela ukuba i-LCD ingasebenzi kakuhle. Kulo mzekelo, kufuneka uhlele i-config.txt file kwikhadi le-SD kwaye ucime esi sivakalisi: dtover-lay=ads7846.
- Ukusebenzisa ngeRaspbian-lite, umyalelo wofakelo lomqhubi kufuneka ube:
UQHAGAMSHELO
Phawula: Qhagamshela i-interface ye-GPIO, i-Raspberry Pi ikhokelela kwi-40 GPIO izikhonkwane, kwaye isikrini sikhokelela kwizikhonkwane ezingama-26, nikela ingqalelo kwizikhonkwane zesikrini ezihambelanayo kunye nezikhonkwane ze-Raspberry Pi xa udibanisa.

FAQ
Q: Kutheni le nto i-LCD ingasetyenziswa ngokuqhelekileyo xa usebenzisa umfanekiso weRaspberry Pi onikezwe yi-waveshare?
A: Ekubeni umfanekiso weRaspberry Pi kunye noguqulelo luhlaziywa rhoqo, ukuba uhlangabezana nemeko apho i-LCD ayinakusetyenziswa ngokuqhelekileyo, nceda ukhuphele uguqulelo lwamva nje lomfanekiso olunikezwa sithi okanye kwigosa. webindawo yeRaspberry Pi kwaye ufake umqhubi wamva nje onikezelwe sithi.
- Qinisekisa ukuba uqhagamshelwano lwehardware luchanekile kwaye umfowunelwa ulungile.
- Qinisekisa ukuba inkqubo yekhadi leTF iqhelekile.
- Xa iRaspberry Pi iqala ngokuqhelekileyo, ukukhanya kwe-PWR kuhlala kuvuliwe, kwaye ukukhanya kwe-ACT kukhanya. Ukuba kufunyaniswe ukuba zombini izibane zihlala zikhanya, kusenokwenzeka ukuba ikhadi leTF alicwangciswanga ngempumelelo kumfanekiso okanye ikhadi leTF linxibelelana kakubi neRaspberry Pi.
- Kucetyiswa ukuba usebenzise i-5V 2.5A iadaptha yamandla kwiRaspberry Pi. Ukuba iRaspberry Pi inikwe amandla yi-USB port yePC, iRaspberry Pi ayinakukwazi ukuqala ngokuqhelekileyo ngenxa yombane ongonelanga.
Kutheni i-LCD ingasetyenziswa ngokuqhelekileyo xa usebenzisa umfanekiso osemthethweni onikwe yiRaspberry Pi?
I-LCD kufuneka ibenomqhubi ofakelweyo ukuze asetyenziswe njengesiqhelo. Ngeenkcukacha, nceda ujonge kwintshayelelo efanelekileyo kwincwadana yomsebenzisi.
Yintoni ubushushu bokusebenza kwe-3.5inch RPi LCD (B)?
Ibakala loRhwebo (0 ~ 70 degrees Celsius).
