<p>In VS Code I installed platform IO and connected my ESP32. The code was written to connect to wifi, grab the data from the web server and display it to the eink. I gave it a title and a progress bar with percentage to clearly show how much I have completed. I also added a Last Updated time stamp and logic to put the ESP to deep sleep and only update each morning after my typical workout time slot.</p>

<p>I later decided it made more sense to show todays date at the botton my the page, making it double as a basic daily calender.</p>
<p>One of the greatest challenges was my desicion to include an image. An easier option would have been to buy an ESP32 with a micro SD card slot to give me an easier way of storing the image. Wanted to make this work without buying anything new I decided to stream the image from my Caddy server directly ro the display. With some AI magic I had a bash script that would convert any image I gave it to a resized monochrome bitmap suitable for the basic eink display. The great thing about using this approach is it makes changing the image for a different future challenge much easier.</p>
