ArduCam OV2640 Mini 2MP SPI Kamara A Rasberi Pi Pico

GABATARWA

A matsayin madadin Arduino, Rasberi Pi Pico ba shi da ikon sarrafawa, ƙwaƙwalwa, da ƙirar CSI, wanda ya sa ba zai yiwu Pico ya yi aiki tare da jami'in ko kowane nau'ikan kyamarar MIPI CSI-2 ba. Abin godiya, Pico yana da zaɓuɓɓukan I/O masu sassauƙa waɗanda suka haɗa da SPI, wanda ke ba da damar kyamarar Arducam SPI don aiki tare da Pico.
Yanzu, ƙungiyar Arducam ta warware dacewar kyamarar mu ta SPI tare da Rasberi Pi Pico. Samu kyamarar tana aiki don demo Detection Mutum!

HANYAR HANKALI

NOTE: Arducam Mini 2MP module na kyamara shine mafita na gaba ɗaya wanda ya dace da dandamali da yawa, sun haɗa da Arduino, ESP32, Micro: bit da Rasberi Pi Pico da muke amfani da su. Don wring da software akan wasu dandamali, don Allah koma zuwa shafin samfur: https://www.arducam.com/product/arducam-2mp-spi-camera-b0067-arduino/
Idan kuna buƙatar taimakon mu ko kuna son keɓance wasu samfuran kyamarar Pico, jin daɗin tuntuɓar mu a support@arducam.com

SAFTWARE SETUP

Don sauƙaƙe kwafa, da fatan za a koma zuwa shafin doc: https://www.arducam.com/docs/pico/arducam-camera-module-for-raspberry-pi-pico/spi-camera-for-raspberry-pi-pico/
Za mu ci gaba da sabunta labaran kan layi gaba daya.

1. Samu direba: git clone https://github.com/ArduCAM/PICO_SPI_CAM.git 
2. Yadda ake samun damar Kamara SPI ta amfani da C.
   Kamara mai goyan bayan direba
   • Tsarin OV2640 2MP_Plus JPEG
   • Tsarin OV5642 5MP_Plus JPEGTattara ɗakin karatu na direba
     Lura: Koma zuwa littafin jagora don yanayin ci gaba: https://www.raspberrypi.org/documentation/rp2040/getting-started/#getting-started-with-c Zaɓi demo kuma shigar da lambar da ke bi don tara ta. (tsoho shine Arducam_MINI_2MP_Plus_Videostreaing)
     Gudun .uf2 file
     Kwafi PICO_SPI_CAM/C/gina/Examples/Arducam_MINI_2MP_Plus_Videostreaing/Arducam_mini_2mp_plus_videostreaming.uf2 file zuwa Pico don gudanar da gwajin.Bude HostApp.exe a ƙarƙashin PICO_SPI_CAM/HostApp file hanya, saita lambar tashar jiragen ruwa, sannan danna Hoton zuwa view hoton.
3. Yadda ake samun damar Kamara ta amfani da Python (akan Windows)
   1. Saukewa kuma shigar da software mai tasowa Thonny Koma zuwa littafin jagora: https://thonny.org/
   2. Sanya IDE: Koma zuwa littafin aikin hukuma: https://circuitpython.org/
   3. Run Thonny
      • Kwafi duk files banda boot.py a ƙarƙashin PI-CO_SPI_CAM/Python/ file hanyar zuwa Pico.
      • Buɗe software na Thonny-> Zaɓi Mai Fassara-> Zaɓi Circuit Python (na kowa)-> Danna Ok
      • Buɗe Mai sarrafa Na'ura don bincika Ports (COM & LPT) na Pico sannan saita lambar tashar jiragen ruwa na Circuit Python (na kowa)
      • Kwafi duk boot.py file karkashin PICO_SPI_CAM/Python/ file hanyar zuwa Pico.
      • Sake yi Pico sannan duba sabon lambar tashar jiragen ruwa a ƙarƙashin Ports (COM & LPT), ana amfani dashi don sadarwa ta USB.
      • Bude shirin sarrafa kyamarar na'urar CircuitPython ta hanyar buɗewa file da Thonny
      • Danna Run, kuma ya bayyana [48], KamaraType shine OV2640, SPI Interface OK yana nufin cewa ƙaddamarwar kyamarar ta ƙare. Lura [48] tana nufin adireshin na'urar I2C na kyamarar OV2640.
      • Bude HostApp.exe a ƙarƙashin PICO_SPI_CAM/HostApp file hanyar, zaɓi lambar tashar jiragen ruwa da aka yi amfani da ita don sadarwar USB, sannan danna Hoton zuwa view hoton.

Idan kuna buƙatar taimakon mu ko cikakken bayanin API, jin daɗin tuntuɓar mu.
