It's been a few weeks since the last update, but this project is still very active...

• I wasn't happy with the display positioning, and it looked even worse in the enclosure. So I modified the circuit board, and now the display is "perfectly" centered.
• I discovered too late I couldn't use GPIO2 as an input. Unfortunately, I routed one of the new pushbuttons to this GPIO, so the button was non-functional. I modified the circuit board and routed it to GPIO16 instead (last free GPIO remaining...).
• The first enclosure had a few issues so I re-designed / re-printed it. It is now fitting perfectly.
• I replaced the yellow / blue display with a blue one. I now have 16 pixels more for graphics, charts...

About the software part :

• The analog monitor is now fully usable (I used it on the field already). It still needs some custom settings
• I wrote the digital monitor, and it is also working very well. Now, I'm trying to find a way to capture / show very fast data (kind of slow signal analyzer). Right now I could sample at 1000Hz reliably, but showing it in a 128x64 graph is not easy...
• I improved the Octoprint 3D printer monitor to better handle connection issues (while roaming)
• I'm actually trying to write the serial monitor code, but this one is giving me headaches...

I'll show pictures and maybe a video in the next build log (paint is still drying).
