I am running WaveForms on my Linux (ARM 64-bit) PinePhone (with the optional Keyboard Case and docking bar), and I absolutely love it! The PinePhone is perfect for 90% of the use cases where I use the AnalogDIscovery2. It makes the whole thing much more portable and bench-top friendly.
I couple things I would ask the WaveForms group to consider;
A) Better touch gesture handling. (I use a tiny Bluetooth mouse right now, without that, it's painful to use WaveForms with touch-only).
B) A way to collapse/shrink the real estate at the top to make more useful pixel space for the traces.
C) Make a 'pacman' package for Manjarno Linux and the like. I installed on Manjarno Linux from the Debian package by coloring outside the lines a little bit. It runs great, very responsive, no issues so far other that what I've mentioned above!
I love this setup very much!
Thanks for the great tools!
