Hello,

I'm looking for a specific header so that I can access the camera data in my custom driver but I do not see it in https://gitlab.com/voxl-public/voxl-sdk/core-libs/libvoxl-cutils. Where can I find camera_image_metadata.h? Thanks.

// ---------------- Save Camera Feed (if enabled) -----------------
if (camera_pipe_fd != -1 && FD_ISSET(camera_pipe_fd, &rfds)) {
    camera_image_metadata_t meta;
    ssize_t ret = read(camera_pipe_fd, &meta, sizeof(meta));
    if (ret == sizeof(meta)) {
        if (img_buffer.size() < meta.size) {
            img_buffer.resize(meta.size);
        }
        ret = read(camera_pipe_fd, img_buffer.data(), meta.size);
        if (ret == (ssize_t)meta.size) {
            cv::Mat image(meta.height * 3 / 2, meta.width, CV_8UC1, img_buffer.data());

            char filename[128];
            snprintf(filename, sizeof(filename), "/data/img_%s_%lld.jpg", TARGET_CAMERA_NAME.c_str(), (long long)meta.timestamp_ns);
            cv::imwrite(filename, image);
        }
    }
}

Hello,

I’m working on a project involving the CubePilot Orange+ flight controller (which acts as an I2C master), and I’d like to know if it’s possible to establish an I2C connection to the VOXL 2 as the slave using the J10/J3 or J19 connectors?

From the VOXL 2 connector documentation, I understand that J10 is labeled as an "External SPI" port, but I’ve read that some SPI interfaces on VOXL 2 can be reconfigured for I2C.

1. Can the J10 connector be repurposed or reconfigured to support I2C communication?

2. If yes, which specific pins on J10 correspond to I2C SDA and SCL?

3. Are there any device tree overlays or configuration changes needed in VOXL 2’s software to enable I2C on J10?

4. Is level shifting required, or is J10 already 3.3V I/O compatible with the CubePilot Orange+?

5. Can https://docs.modalai.com/voxl-i2c-io/ be used or would a custom driver need to be written?

Thanks in advance for the clarification.

I am following the tutorial for connecting the VOXL2 to the local wifi network using the purchased wifi adapter below but I'm unable to successfully connect.

Illegal usage
Description:
        Configure the Wi-Fi mode.

Usage:
  voxl-wifi getmode
        Print the current mode (softap of station)

  voxl-wifi softap <ssid>
        Set Wi-Fi to Access Point mode.
        Password defaults to '1234567890'

  voxl-wifi station <ssid> [password]
        Set the Wi-Fi to station mode and connect to the AP with provided SSID
        and (optional) password.  Note: if your password has special characters
        surround it with quotes.

  voxl-wifi -f
        Set the Wi-Fi to Access Point mode and SSID to 'SSID'
        Password defaults to '1234567890'

voxl2:/$ voxl-wifi station "Alpha Bravo" "Password"
Cannot find device "wlan0"
Device "wlan0" does not exist.
Cannot find device "wlan0"

I have read the documentation on https://docs.modalai.com/voxl-tflite-server/. Is there additional documentation available?

I'm interested in if we can use a test image that we can deliver to the VOXL2 chip (instead of using the cameras) to test the image segmentation logic.
