linuxSmartie

Alphanumeric LCD software for Linux (kind of LCDSmartie for Windows but no GUI, no config file, no plugins, no Windows). Written with C++26, should compile with at least C++20.

Hardcoded to work with 4x40 character display because that's what I have and I don't plan on using anything else.

Vaguely inspired by suckless software philosophy.

The config is the source code

Same as plugins. Just write more features scrub, learn some C++, damn

TODOs

In the LCDDisplay lib, reimplement all the features I have in picoSmartie + maybe finally add keypad support for both so I can toggle backlight (?) or change screens if I want any
Screens could be automatic tbh, like if it detects media playing it switches to media screen, if GPU power > 80W it switches to main (hwmon) screen
Gonna need custom chars for sure at some point
Measure execution time of main loop, if it's close enough to 1000ms, add network monitoring
Add more getters in general, CPU temp/clock/power/Vcore would be the big one
GPU is about as done as it's gonna be
Needs bar graphs still
Parse gpu_metrics for GPU metrics

LCD layout

It looks something like this

****************************************
0.4      0    ||09:30:36|         124fps

Ok but what does it all mean

In general left side is CPU/system stuff, right side is GPU stuff

{act core cnt} {whea} {time} {bar/1cpu%}{bar/AllCPU%}{TIME}{gpu%} {xbat} {fps}

{dieAvg}/{cache}/{iod}C {ram}GB  {vram}GB  {edge}/{junction}C

{cpuPpt}W {cpufan}R {wallPow}W {gpufan}R {gpuPpt}/{cap}W {gpuBoard}W

{cpuV}V {avgCpuFreq}MHz {gpuCoreClkCap} {gpuCoreClk}/{gpuMemClk}MHz {gpuV}V

Not all of this will be possible ofc but it's a start

Raw LCD Smartie lines below:

So what's still missing

Tasmota wall power, doable
Average CPU freq, doable
Per-core CPU load, doable but annoying
FPS counter, maybe possible?
Active core count, probably impossible but loadAvg is better?
GPU board power, probably impossible, it was estimated on windows anyway
CPU cache/iod, likely impossible, zenpower doesnt show it
GPU clock limit, probably impossible, amdgpu doesnt show it?
CPU fan, likely impossible, no modules
