Touch screen problem on PiCore (bug/ just some tslib setting?)

[harashoo]

Yeah, you are right paul.
1) I did correctly, that's not it.
2) Here turned out to be the problem. I edited jivelite.sh via SFTP on windows. When I opened the file in the terminal, it turned out that "^M" was automatically added to each line. Now everything works as it should. Thank you!

Just be aware that pcp_startup will get over written during upgrades.

nothing looks wrong with what you posted, so the go to answers are
1). Script is not marked executable.
2) you edited the script on a windows machine and did not change it to linux line endings when you uploaded.

[harashoo]

Thank you paul for answer. I try diffrent, for example:

#!/bin/sh


EVENTNO=$(cat /proc/bus/input/devices | awk '/wch.cn USB2IIC_CTP_CONTROL/{for(a=0;a>=0;a++){getline;{if(/mouse/==1){ print $NF;exit 0;}}}}')

# Define custom JogglerSkin size
export JL_SCREEN_WIDTH=800
export JL_SCREEN_HEIGHT=480
#export JL_SCREEN_WIDTH=1024
#export JL_SCREEN_HEIGHT=600

export JIVE_NOCURSOR=1
export SDL_VIDEODRIVER=fbcon
export SDL_FBDEV=/dev/fb0
export TSLIB_TSDEVICE=/dev/input/$EVENTNO
export SDL_MOUSEDRV=TSLIB

## Just debugging info

while true; do

sleep 3
done​

Copy of original etc. and jivelite does not want to run. But when I edited pcp_startup.sh now everything work well:

if [ "$JIVELITE" = "yes" ]; then
    echo -n "${BLUE}Starting Jivelite...${NORMAL}"
    eventno=$( cat /proc/bus/input/devices | awk '/wch.cn USB2IIC_CTP_CONTROL/{for(a=0;a>=0;a++){getline;{if(/mouse/==1){ print $NF;exit 0;}}}}')
    if [ x"" != x"$eventno" ]; then
        export JIVE_NOCURSOR=1
        export TSLIB_TSDEVICE=/dev/input/$eventno
        export SDL_MOUSEDRV=TSLIB
        export SDL_MOUSEDEV=$TSLIB_TSDEVICE
    fi​

Please post the output of

cat /proc/bus/input/devices

and the contents of your j custom jivelite script.

Hi, guys.
I'll link to the topic. I have 7" HDMI 1024x600 display. After connecting and installing jivelite, the image displays normally. The touch works but unfortunately not quite correctly. The cursor is shifted and presses in a different place. I ran the calibration and then the test and it looks ok. Unfortunately, after creating custom jivelite.sh (executable) in /mnt/mmcblk0p2/tce/ and backup changes, Jivelite does not want to run. Even though it is the copied original file from /opt/jivelite/bin/jivelite.sh. Any idea what's wrong?

[kjansik]

Hi Izocad,

did you solve the problem?

[kjansik]

I didn't, and it works, so negative.

[Izocad]

Hi,

try to set in jivelite.sh joggler resolution to 800x480:



and custom resolution:



Can be set in Tweaks Web GUI also. I would do it in any case!

Afterward select Joggler skin or 800x480 skin.

Do I also need to tweak the config.txt to that resolution?

[kjansik]

Izocad,

try to set resolution to Joggler 800x480, as in my post higher....

Concerning the calibration: if you doubt it is OK, do ts_test.

[Izocad]

Yes you are going to want to match the resolution against an available skin 1024x600 is a good resolution.

As for you jivelite.sh script. The awk command in the EVENTNO line is a search command, so you need enough text to match the line from /proc/bus/input/devices.
Also make sure your frame buffer is set to the right device. Also, "#" at the beginning of a line is a comment, which doesn't get executed, so make sure those are gone too where you need to set a value.

EVENTNO=$(cat /proc/bus/input/devices | awk '/QDtech/{for(a=0;a>=0;a++){getline;{if(/mouse/==1){ print $NF;exit 0;}}}}')
export JIVE_NOCURSOR=1
export SDL_FBDEV=/dev/fb0
export SDL_MOUSEDRV=TSLIB​
export TSLIB_TSDEVICE=/dev/input/$EVENTNO

while true;
do /opt/jivelite/bin/jivelite
sleep 3
done

I'm using the Grid skin 1280x800 so that resolution matches.
Are there any other things I need to be aware of?

And are the values I'm getting during calibration correct? The left and right one seem to be the same value.

tc@woonkamer:~$ sudo TSLIB_FBDEVICE=/dev/fb0 TSLIB_TSDEVICE=/dev/input/event0 /usr/local/bin/ts_calibrate

Is it really so easy? I read many posts about issues... but i will try in few days when i'll receive the display and let you know.

Yes, pCP is setup to use the official screen by default. About the only thing you have to do is flip the screen 180 depending on how you case is configured. Which that is an option on the tweaks page.

[kjansik]

Because I have this screen: https://www.aliexpress.com/item/1005004530893933.html
Skin is Grid 1280x800

With these options, have tried any combination on and off but touch is never accurate

export JIVE_NOCURSOR=1
export SDL_FBDEV=/dev/fb0
export SDL_MOUSEDRV=TSLIB​
export TSLIB_TSDEVICE=/dev/input/$EVENTNO​

Have also tested with only this in the script, which give me the same result:

while true;
do /opt/jivelite/bin/jivelite
sleep 3
done​

I've tested them all on and off but no combination seems to work without issue.
What do you have in your script?

Hi,

try to set in jivelite.sh joggler resolution to 800x480:

# Define custom JogglerSkin size
export JL_SCREEN_WIDTH=800
export JL_SCREEN_HEIGHT=480

and custom resolution:

# Set custom screen resolution
usr/sbin/fbset -xres 800 -yres 480

Can be set in Tweaks Web GUI also. I would do it in any case!

All you need to do is install Jivelite from the pCP web interface. Everything should then work automatically.

[Paul Webster]

Is there a project which can be a guide to use the official raspberry 7 inches display with pCP ?

Check the resolution... Why 1280x800? what skin is set?
