¶ 📝 Process
- Users can connect to the device using the "PLUG IN" button.
- Users can choose to either “Stream Video” or "Capture Image".
- Upon selecting "Stream Video," users can set the video resolution from the available options. There are two resolutions available for this particular video: 320240 and 640480.
- Click on the "Start Streaming" button to stream the video.
- Along with the video streaming process, users can change the features of the video by changing the parameters available just below the stream video button, such as brightness, contrast, saturation, EV, etc.
- Users can use the "Stop Streaming" button to stop the video streaming process.
- “Reset Defaults” will reset the setting to the system default values.
- The "Capture Image" process can be performed in a similar way as above.

¶ 📑 Frequently Ask Questions
Q1: What are the key interface considerations when integrating the QCIOT Arducam Mega IoT SPI Camera with Renesas RA Cortex‑M MCUs?
A: Ensure that the SPI signal levels match the MCU’s I/O specifications. Follow the recommended PCB layout guidelines to maintain signal integrity at high SPI speeds and verify that the SPI clock polarity and phase settings (CPOL/CPHA) are configured to match the camera’s datasheet. Additionally, ensure that proper power sequencing and decoupling are in place to stabilize the sensor during operation.
Q2: What troubleshooting steps should I follow if the camera fails to capture images as expected?
A: Start by verifying that the MCU firmware correctly initializes the SPI interface and that the sensor’s configuration registers are set according to the Arducam documentation. Check physical connections (cabling, solder joints) and measure supply voltages. Use a logic analyzer or oscilloscope to monitor SPI communication for protocol errors or mis-timed signals. Also, confirm that the sensor’s power and clock signals are stable throughout the initialization process.
