ArduCAM Mini 2MP User manual

QUICK START GUIDE
SPI Camera On
Raspberry Pi Pico
(Arducam Mini 2MP)
INTRODUCTION
As an alternave to Arduino, Raspberry Pi Pico lacks pro-
cessing power, memory, and a CSI interface, which makes
it impossible for Pico to work with the ocial or any MIPI
CSI-2 camera modules. Thankfully, Pico has a wide range of
exible I/O opons includes SPI, which enables the Ar-
ducam SPI camera to work with Pico.
Now, the Arducam team has solved the compability of
our SPI camera with Raspberry Pi Pico. Get the camera
working for the Person Detecon demo!

SOFTWARE SETUP
To facilitate copying, please refer to doc page: hps://
www.arducam.com/docs/pico/arducam-camera-module-
for-raspberry-pi-pico/spi-camera-for-raspberry-pi-pico/
We will keep online up-to-date connuously.
1. Get the driver
2. How to access SPI Camera using C
2.1 Cameras supported by the driver
• OV2640 2MP_Plus JPEG format
• OV5642 5MP_Plus JPEG format
2.2 Demos provided
2.3 Compile the driver library
Note: Refer to the ocial manual for the development
environment: hps://www.raspberrypi.org/
documentaon/rp2040/geng-started/#geng-started-
with-c
Choose the demo and input the following code to compile
it. (default is Arducam_MINI_2MP_Plus_Videostreaing)
git clone hps://github.com/ArduCAM/PICO_SPI_CAM.git
2.4 Run the .uf2 le
• Copy the PICO_SPI_CAM/C/build/Examples/
Arducam_MINI_2MP_Plus_Videostreaing/
Arducam_mini_2mp_plus_videostreaming.uf2 le to Pico
to run the test.
• Open HostApp.exe under PICO_SPI_CAM/HostApp le
path, congure the port number, and click Image to view
the image.
cd PICO_SPI_CAM
mkdir build
cd build
cmake ..
make
3. How to access Camera using Python
(on Windows)
3.1 Download and install developing soware Thonny
Refer to the ocial manual: hps://thonny.org/
3.2 Congure the IDE
Refer to the ocial manual: hps://circuitpython.org/
3.3 Run Thonny
• Copy all the les except boot.py under PI-
CO_SPI_CAM/Python/ le path to Pico.
• Open Thonny soware->Select Interpreter->Select
Circuit Python(generic)-> Press OK
• Open Device Manager to check the Ports(COM & LPT)
of Pico and then congure port number of Circuit
Python(generic)
• Copy all the boot.py le under PICO_SPI_CAM/
Python/ le path to Pico.
• Reboot Pico and then check the new port number
under Ports(COM & LPT), it’s used to USB communica-
on.
• Open the camera drive program CircuitPython device
via opening le on Thonny
• Click Run, and it appears [48], CameraType is OV2640,
SPI Interface OK means that the inializaon of the
camera is completed. Note [48] refers to the I2C
device address of OV2640 camera.
• Open HostApp.exe under PICO_SPI_CAM/HostApp le
path, select the port number used for USB communi-
caon, and click Image to view the image.
