Create a workflow for developing an information dashboard for sports events on e-paper displays. The workflow should include: 1) Identifying key data points users need (e.g. schedule, results, rankings); 2) Designing minimalistic display layouts optimized for e-paper; 3) Setting up API connections to fetch live data; 4) Implementing a local application to process and push data to the device; 5) Creating an automatic rotation system for multiple information cards. Provide sample code for the data processing and display generation components.
