[linux-sunxi] zet6221 ts driver testing

[alex allss]

Hello, I make open-source driver for Zet6221 Touchscreen ,and have
workable prototype, still buggy at all.
I need testers who have tablets with this IC an can test prototype,
this IC can have different configuration,
firmware, depend screensize, wires connections, etc. It requred
testing on hardware different than I have.

[Francis Mortanian]

I have a tablet with this IC running on a sun4i, I'd love to test your driver. The touchscreen is the last bit on this I need working.

[alex allss]

are you using android or debian ?

2013/3/15 Francis Mortanian <nautilus...@gmail.com>:

[Francis Mortanian]

debian sid or debian squeeze, but if you're asking if I need a single-touch version I don't mind patching my xorg for multitouch if that's what the driver is setup for.

[alex allss]

Firstly you can try insmod this, (for 3.0.62+ kernel) or I have to
build it for other, but costs time.
1) test coordinate mappings
2) fails using
cat /proc/kmsg

2013/3/15 Francis Mortanian <nautilus...@gmail.com>:

[Francis Mortanian]

There's no way this will be compatible with any kernel I'm using, I'll need the source code.  Is there any way you can check this into a github or gitorious repository?

[alex allss]

I on early stage of development, code not cleaned for merge to
linux-sunxi. After I get stable version I send patch to ML, but I need
testings...

What kernel are you using, and what better for you, patch, github repo
with patch merged, or I can simply send you files (zet6221.ko
zet_ts.h) and you have to connect to build system (add lines to
Kconfig/Makefile)

I can give you sources but you have to add

2013/3/15 Francis Mortanian <nautilus...@gmail.com>:

[Francis Mortanian]

I don't mind doing that, I already have the lines there for my own incomplete Zet6221 driver development.  You don't need to be shy about code cleanliness this early in the game.

I'm using the 3.0 branch from Git at the moment.

[alex allss]

core files here:
https://github.com/wingrime/zet6221-ts-drv

you must copy this to drivers/input/touchscreen/
add driver to Makefile/Kconfig

please report testing results and feel free send pull requests

I have a table on A13 (sun5i) with Zet6221 Touchscreen
linux-sunxi-3.0 and linaro rootfs
I copied zet6221.c and zet6221.h to drivers/input/touchscreen/
How add driver to Makefile/Kconfig ?

Not sure if this drive works or is complete. I know wingrime was working
on it, not sure on its status.

[alex allss]

this driver workable (for linaro)

present problems related user-space soft:
debian have problems with Xorg (new mt protocol support?) feel only
touch events, not move
also xfce have problems (window headers )

use this branch in my repo don't forget add to make menuconfig

plase send me original full fex

It look like you fex is invalid
try set

[Francis Mortanian]

I finally got this going on my Q88.  For xorg I had to modify /usr/share/X11/xorg.conf.d/50-multitouch.conf and add a pattern match on "MatchIsTouchscreen" so it would be applied.

(To everybody else, if it registers touch events without coordinates, you probably need this.)

So... confirmed working on the Q88, if nothing else.

I had to edit my fex file to change zet6221-ts to zet6221_ts for the module to load.

Excellent work on this module, it's very well done.  If I find any bugs I'll try to hack up a patch.  If I can't I'll let you know anyway.

Thanks for your hard work alex!

Hello
I need to include ZET6221 driver for 3SC6410 FriendlyArm board.
Can someone send source files ?

[Olliver Schinagl]

I think you confuse linux-sunxi with ZET, so maybe ask them.

As for our RE sources or submitted sources, I'm sure you are able to use
google and find what was posted to this list (which is publicly
archived) and/or check wingrime's git account for his efforts.

Heck even the first few google results for zet6221 yield the proper
results, so do at least SOME homework.

Dear Oliver

Thank You for reply.

I'm experienced in making hardware and PIC ASSEMBLER.
I build my own PCB with 3SC6410 stamp module and I want to use ZET6221 capacitive TSP and AT070TN94 S70 LCD.

My TOTAL LINUX experience is 5 days and 1 day programing in C.So I need to compile my LINUX kernel.

A friend helped me to install compiler and toolchain. I learned how to configure and make zImage, how to add new driver. But when compiling there are some errors. I made corrections and zImage is ready now will investigate what happens if the driver works ...


If You help me to get it working would be fine. I just wanted to get working driver and adapt GPIO to my system. 

Best Regards

ILIAN

Now this is a far more civilized mail.

We received sample code from ZET a long time ago and is uploaded to our
wiki I think and if I'm not mistaken posted on this mailing list, but it
wasn't something you could just drop in and compile.

Wingrime took this code and wrote a sample driver,
http://github.com/wingrime that should work under linux.

The latest lichee kernel from Allwinner actually also has a driver in
their SDK, so should also be useable.

Due to the nature of many touchscreen controllers, it's a hit/miss
thing, sometimes a driver works, sometimes it needs to be
tweaked/configured slightly different, it really depends on the
touchscreen driver IC.

Dear Mikey

The driver is only one of the brunches that you need to get the TSP working.

I'm pretty new to linux and C programing but had a look at lot of files in OS. As you have other platform file names will differ from those I send. Just get this in mind:

0.You have to be sure that TSP pins are properly conected to driver expectations and IO pins definitions in your kernel - /arch/arm/mach-s3c64xx/mach-mini6410.c

1.You have to instantiate I2C device - Documentation/i2c/instantiating-devices

2.Define TS platform device - /arch/arm/mach-s3c64xx/dev-ts-mini6410.c

3.Here is the driver - /drivers/input/touchscreen/zet6221_i2c.c

4.I don't know if this is important - /arch/arm/plat-samsung/include/plat/ts.h

You can try your driver with command modprobe drivername (modprobe zet6221_i2c for my one)

As I did not run my ZET6221 TSP yet because I had another work, will be interesting with your work. Pls, send info. If you have some questions I can try to answer also.

If driver successfully read configuration when starting, and than not see any input, so looks like irq not working , possible cases:

1. Irq pin not connected
2. Irq not configured right way

Did you checkharware connection ? If you can write your own simple program to read GPIO pin you can check if the ZET6221 INT pin is connected to the GPIO you expect. When you touch the TSP INT signal is hold down "0" for a second if I2C not read by CPU.

You should have:

I2C_BOARD_INFO("ft5x06_ts", 0x55),        .irq = IRQ_EINT(4) - this example is for other TSP but
