task id: drawing-tablet-experiments2024-07-08 14:38: Play with Carsten's drawing tablet #drawing-tablet-experiments
2024-07-08 14:40: It works out of the box #drawing-tablet-experiments
2024-07-08 15:13: Initial polling program working! #drawing-tablet-experiments
X max: 21600, Y max: 13500, Physical units: 8.5 x 6 inches,
Along the Y-axis, this evenly comes too 2250 pixels/inch. The X axis is about 2541.1764. Huh.
2024-07-09 08:22: Drawing tablet experiment vs demo #drawing-tablet-demo #drawing-tablet-experiments
There is a bit of overlap here. I want the end of the "drawing tablet experiments" to have sound, and the "drawing tablet demo" to build up from that initial demo, tuning the sound better, and adding an abstraction that will make it easy to go between tablets.
2024-07-09 09:00: Some experiments with the wacom. #drawing-tablet-experiments #timelog:00:36:51
2024-07-09 09:01: What model is this Wacom Tablet? #drawing-tablet-experiments
Wacom Intuos PT M 2, according to dmesg. Researching.
More specifically: CTH-690 [Intuos Art (M)] (using product/vendor ID lookup).
Super cheap to buy on ebay.
2024-07-09 09:25: I have to learn about the finger tracking information here #drawing-tablet-experiments
Is it multi-touch?
2024-07-09 09:39: ABS_MT_SLOT keeps track of multi-touch points I think. #drawing-tablet-experiments
I'm counting 10 points multitouch.
X axis resolution: ~2143 (2150?), Y axis resolution: ~1333
2024-07-09 09:49: Time to make some noise. #drawing-tablet-experiments #timelog:01:07:40
2024-07-09 09:54: gotta build libsoundio on this device to get jack backend #drawing-tablet-experiments
2024-07-09 09:57: voxboxOSC builds and runs. now to extract the relevant bits. #drawing-tablet-experiments
No need for the OSC bits, but the sound and DSP are a good start.
2024-07-09 10:13: time to get the code tablet hooked up #drawing-tablet-experiments
udev permissions are in order.
2024-07-09 10:33: Only set pitch when pen is down. #drawing-tablet-experiments
2024-07-09 10:47: It works. Gotta place with this thing now. #drawing-tablet-experiments
2024-07-09 10:54: Adding files and committing. #drawing-tablet-experiments
2024-07-09 19:04: Troubleshooting xp-pen tablet. #drawing-tablet-experiments #timelog:00:23:34
2024-07-10 12:02: Trying out my new x-pen #drawing-tablet-experiments
2024-07-10 12:06: It works #drawing-tablet-experiments
32767 both directions. which potentially poses a problem if you want the aspect ratio.
Just measured. 4x3 inches. so 4:3 ratio.
In theory, it's 15 bit resolution, which is great considering the size. But is it actually 15-bit? or just upsampled.
2024-07-10 12:11: udev rules to use without sudo #drawing-tablet-experiments
Also wondering: how to get max resolution automatically of touchpad?
Ah, yes it does <<misc/libevdev_get_abs_maximum>>
2024-07-10 12:20: Disabling the tablet from sway. #drawing-tablet-experiments
Note to self: I gotta organize this script better.
2024-07-10 12:24: Hook-up to singer #drawing-tablet-experiments
2024-07-10 12:38: Tongue shape control. #drawing-tablet-experiments
2024-07-11 08:35: Officially concluded. #drawing-tablet-experiments
Now onto demo
Can it work on linux okay? I can I use libevdev with it?
