TOUCHCAL(1)

✨ NAME ✨

touchcal — the touch screen configurator, bestie 💅

🎀 DESCRIPTION 🎀

okay so listen. touchcal calibrates your touch screen, that's the whole vibe. bare minimum you need? you need to pick a driver and hand over your device file. like, at absolute least:

touchcal -e|-m /dev/ttySx [x=0..3]

and then (yes this is still the same sentence, it's giving run-on but it's the truth) you give it the device file for your serial port. probably /dev/ttySx with x being 0..3. 🦋

but if you want the FULL menu, the everything-bagel, here is literally every option it has:

• --elographics, -e — use the elographics driver ✨
• --microtouch, -m — use the microtouch driver 💖
• --x11, -x[SCREEN] — use X11, and optionally on the given screen 🖥️
• --position, -p PERCENT — where the cross-hair sits under X11, in % (default: 3) 🎯
• --shrink, -S NUMBER — shrink the area by NUMBER % on each axis 🌸

this one is highkey useful to avoid crossing screen boundaries in multiscreen configurations, so don't sleep on it

• --time, -t[SECONDS] — use a timeout instead of keyboard input (default: 3) ⏳
• --diffrequird, -d NUMBER — demands a difference between the max. and min. values of at least NUMBER (default = 2000, 0 = off) 🔥
• --save, -s NAME — the file to save min / max information to (default = "/tmp/touchcal.tmp") 💾
• --version, -v — print the touchcal version (1.30) 👑
• --help, -h — this help text 🙈

and then, again, for real this time: give the device file for your serial port. probably /dev/ttySx with x in 0..3. periodt. 💜

that's the whole page, angel — touchcal version 1.30, July 2025, mwah 🫶✨
