Does installing and running Makie (I saw use of it in the WiringPI repo) give you time to refill your water, make tea, make scrambled eggs, cook rice, smoke a turkey ...?

Per Julia LTS (1.10), you could refill water, make a cuppa tea, and sit back down to continue hacking on the Pi! 🍵 Story is great; Pi 4 only has 4GB RAM. Did expand swap to 2GB (overkill) for compiling but... Not bad. Will share future updates! 🔮 No problems with #Julialang in my non-hobby work. 🤓

I'm not working on that kind of problem now but it sounds like you could model a system on PC, develop a control law in the simulation, then move the control portion in Julia to a Raspberry Pi and test with hardware. Skip the part where you port the control law to micropython or C. Very cool!

Oh that sounds fascinating! What sorts of projects do you tend to work on? I am slowly rediscovering my love of hardware hacking and hardware engineering so would love to hear more!

That was at a previous employer and I'm not doing that now, but my intro to Julia was using the DiffEq tools to develop control algorithms or analyze behavior of long-existing ones, around substitute in medical devices doing things like control of ultrasound actuators, or pressure or vacuum.

So embedded systems running C code to read sensors, implement control law, drive actuators, in a variety of electromechanical systems.

I was wanting to do it all in one place for less translation and porting.

Oh that's not bad at all! I remember either Plots or one of the stripped down DiffEq packages basically taking forever. It churned for an hour or so and I killed it. At the time I was exploring options for prototyping platforms. I was doing simulations on PC but testing on pyboards.
