Hello
I try to run Waveshare 7" hdmi (C) on picoreplayer (tinycore) with TSLIB 1.16 compiled for this system.

`tc@piCorePlayer:~$ cat /proc/bus/input/devices
I: Bus=0003 Vendor=0eef Product=0005 Version=0110
N: Name="BYZHYYZHY By ZH851 Mouse"
P: Phys=usb-20980000.usb-1.3.3/input0

`

When I use ts_calibrate with event1, the calibration does not work: crosshair is well displayed, bt when I press top-left corner, it jumps immediately to bottom right or further. at the end the calibration file is not correct ad the touchpad does not work.

`#module_raw input

module_raw waveshare vid_pid=0eef:0005 len=25

module pthres pmin=1

module debounce drop_threshold=40

module dejitter delta=100

module linear

`
I tried the debounce mode, no success.

If i tried module_raw waveshare vid_pid=0eef:0005 len=25 i obtained ts_read bad file descriptor.

I'm stuck completly. Don't know if this is a bug or a wrong config.

Thank you

first of all, please provide the (full) output of either evtest or evemu-record when you do one "tap" on the screen.

what I suspect is that you should use "module_raw input" instead of "module_raw waveshare..."

Hello
I've tried also module_raw input initially, same issue. That's why I change to waveshare.
how an I launch evtest & evemu-record ? is that part of standard tslib binaries ? (I'm using Picoreplayer on tincore)

Hello, by chance evtest is available as a package. Here is the result with one tap. (and module_raw waveshare)

^Ctc@piCorePlayer:~$

evemu-record is not available unfortunately.

I tried with module_raw input (after backup & reboot), here is the evtest output:

I succeed to get a debug-enabled tslib for picoreplayer (Thanks Ralphy).

Here is the logs printed on the screen when launching ts_calibrate.
I observe that on my touchescreen, the Bottom-right corner step was skipped: I didn't press on it, it jumps from Top-right to Bottom left

Hope this helps.

Thank you
