4.3. Refreshing Content
Content on the e-paper displays is refreshed through the ESL Waveshare Cloud Platform. This platform allows you to upload new images or data, which are then transmitted wirelessly to the displays via the ESL-Gateway-AP Base Station.
- Prepare Content: Create or select the image/text content you wish to display. Ensure it is formatted correctly for the 3.5inch display (384 x 184 pixels resolution).
- Upload to Cloud Platform: Use the cloud platform interface to upload your prepared content.
- Assign to Displays: Assign the uploaded content to specific e-paper displays or groups of displays.
- Initiate Refresh: Trigger the refresh command from the cloud platform. The base station will then transmit the new content to the assigned displays.
Note: The e-paper displays only consume significant power during the refresh process. Once the content is displayed, they require no power to maintain the image.
