It’s been a while since the last dev blog, although I feel like I didn’t make much progress. I “wasted” a lot of time programming things that in the end I had to redo. The thing is, I had to choose how I wanted to handle the communication between the web app, the phone, the ESP32, and everything else, and there are lots of ways to do it. In the end, I decided to build my own web app that only I can access, because it stores my information. Then I generate an API so the ESP32 can download the picture to display on the e-ink screen. I worked on the logic for that. Basically, I made a script that takes a screenshot of every item and sends one depending on the input. The ESP32 sends the input and the server returns the correct screenshot. The code also automatically generates a C array of the photo for the ESP32. Lastly, I organized the project, because it was getting messy.
