# linuxSmartie
|
|
Alphanumeric LCD controller software for Linux (kind of LCDSmartie for Windows but no GUI, no config file, no plugins, no Windows). Written with C++26 (`-std=c++2c`), will need at least gcc 14 to compile.
|
|
|
|
Hardcoded to work with 4x40 character display because that's what I have and I don't plan on using anything else. Uses Matrix Orbital protocol over serial. Should work with most other display sizes by modifying `src/LCDDisplay.cpp`. Best of luck.
|
|
|
|
Vaguely inspired by suckless software philosophy.
|
|
|
|
## The config is the source code
|
|
Same as plugins. Just write in more features scrub, learn some C++, damn
|
|
|
|
## TODOs
|
|
- Define a "logging library" #define LOG(fmt, param) std::println(fmt, param), only log #ifdef LOGGING
|
|
- Extra screens support perhaps? just halt sensors monitoring thread and print another struct on display if needed, have a semaphore or sth
|
|
- Media playback screen
|
|
- 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 in media screen and GPU power > 80W it switches to main (hwmon) screen
|
|
- Network monitoring would be sick
|
|
- Centering function for the in utils `std::string center(str, len)`;
|
|
- Suspend/resume still broken but also I don't really use it soooo...
|
|
- Try to be C++26, avoid globals, wrap in namespaces, use naming conventions, use classes, avoid pure C way of doing things unless it makes more sense
|
|
|
|
## LCD layout
|
|
It looks something like this
|
|
```
|
|

(on LCDSmartie)
|

|
### 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
|
|

### So what's still missing
|
|
- 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, gpu_metrics doesnt show it?
|
|
- CPU fan, likely impossible, no modules for my current motherboard
