0.2.0 (2025-03-31)

0.2.0 OS Update Details

New Features

1) New base board

As we introduce our new family member reCamera Gimbal (yay!), reCamera OS now supports new base board that feature CAN as the new interface to control other hardware such as servo motors.

In version 0.2.0, reCamera OS will distinguish between B1 default based board and B4 CAN base board. If B4 board is detected, the associated script and flow json will be loaded to control the gimbal.

2) Reorganize Node-RED palettes

We have reorganize the Node-RED palettes as there are more nodes now for the reCamera series.

1. node-red-contrib-sscma: This palette is the same as the one in the previous version where you can find vision AI associated nodes.

   • camera
   • model
   • preview
   • save
   • stream

2. node-red-contrib-recamera: This palette is separated by 2 categories: reCamera and reCamera Gimbal. Nodes are associated with the hardware interfaces of the device.

   • light
   • set motor angle
   • set motor speed
   • get motor angle
   • get motor speed
   • angle to CAN
   • CAN to angle

3. node-red-contrib-seeed-canbus: This palette is for the CAN bus communication. You can use it not only in reCamera Gimbal, but also in other devices that use general CAN bus communication.

   • CAN read
   • CAN write

3) Update pop-up window

We have added a pop-up window to notify users about the update. The window will appear when the device is connected to the internet and the update is available.

Bug Fixes

1) Switch auto detecting nearby device to manual detecting

We have switched from auto detecting nearby reCamera devices to manual discovery due to device hardware limitations. Continuous auto-detection of nearby devices consumes a great amount of CPU, which can cause lag in the device's functionality. Considering this feature's usage frequency, switching to manually discover will ensure the stability and performance of the device.

2) Loading animation only shows on workspace and dashboard tab.

In this way, you can access basic web settings such as network or terminal when the device is ready. No need to wait for Node-RED to get started.

3) Use browser to acquire update information instead of the device itself.

4) Minor UI fixes.

reCamera Gimbal Details

All gimbals will be installed 0.2.0 by default from the factory.

1) Default gimbal dashboard

This gimbal dashboard gives you a plug&play experience of the gimbal. You can control the gimbal by using the joystick, sliders to control the yaw and pitch angle or speed manually. You can also select one of the targets in the dropdown list to ask gimbal to track. There are also 4 shortcut buttons to control the gimbal in different ways. You can also adjust the PID parameters on the second tab to tune the gimbal's performance.

2) Gimbal dashboard flow

The above dashboard is based on the flow below. You can follow the flow to understand the logic of gimbal nodes and twist them to your own needs.

To view each node's details, you can click the node and click the info button on the upper right side of the node to see how to use the nodes.

0.1.5 (2025-01-22)

3. Camera node:

• Enhanced error feedback for camera hardware dropping.

c) Pre-installation of Node-RED Palettes

Two Node-RED palettes, @flowfuse/node-red-dashboard and node-red-contrib-os, are pre-installed to facilitate the construction of a web demo for the dashboard.

d) Default Flow for Node-RED

The dashboard flow is pre-installed as the default flow in Node-RED. This allows users to immediately preview the camera feed processed by AI upon opening and simplifies subsequent debugging procedures. *Please note that if you previously have content in your flow, we will not overwrite your flow with this default flow. You can visit GitHub or SenseCraft to view the dashboard flow content and integrate it with your project to let your project have an interactive interface on smart devices.

e) 4. Node-RED Palette Management

The functionality to add and delete Node-RED Palette has been enabled for Palette Management, enabling seamless integration with other palettes within the community.

f) Node Information Added

2) Web Update to 1.1

a) Web Restructuring

ip_address/#/dashboard is the default page when entering ip address in the browser. It is the dashboard made by node-red.

ip_address/#/workspace is the workspace to edit node-red flow.

ip_address/#/init is the original web interface. Now serve as the basic weeb for essential functions such as Wi-Fi, security, system update, terminal, and credential. Additionally, it is now framed within the default dashboard flow.

b) SenseCraft Integration

The reCamera dashboard/workspace can now be accessed via SenseCraft, unlocking powerful capabilities like application management and auto-saving.

c) Auto-saving in SenseCraft

Applications can now be automatically saved on SenseCraft every 15 seconds once you logged in, ensuring data integrity and ease of use.

d) Credential Management

e) Workspace UI Changes

The workspace UI has been updated to provide a more intuitive and user-friendly experience.

3) Update Instructions

1. Ensure that your reCamera is connected to a stable network and has an adequate power supply.
2. The camera will automatically detect the available OTA update. Go to tab "System" and hit the button "check" to pull the update.

3. During the update, it is crucial not to turn off the camera or disrupt the process in any way. The update may take several minutes to complete, depending on various factors such as network speed and the size of the update.
4. Once the update is successfully concluded, the interface will show the "restart" button. Wait for the reboot process to finish before attempting to use the camera again.

4) Troubleshooting

a) Update Failure

If the update fails, first check your network connection. Ensure that you have a stable and reliable connection. If possible, try switching to a different Wi-Fi network or troubleshooting your current connection. If the problem persists, please contact our support team at techsupport@seeed.io or join our Discord. Provide detailed information about the error message (if any) and the steps you have taken prior to reaching out.

b) Node-RED Flow Preservation

If you have previously developed with Node-RED and configured a custom flow for your specific task, this update will not overwrite your existing flow with the dashboard demo flow. After updating to version 0.1.4 and attempting to visit 192.168.42.1, you may encounter an error indicating that you cannot access the dashboard due to the absence of the dashboard flow. In such a case, please visit GitHub to download the default dashboard flow or clone it from SenseCraft. You can directly import the dashboard flow to your device or integrate it with your own custom flow as per your requirements.
