How to use fbtft for TFT01-2.2S LCD? #428

Closed rezaee closed 6 years ago

rezaee commented 8 years ago

Hi I have an arm-based board(nanopi m1)that has 40 pins GPIO similar to raspberry pi and Debian Jessie OS. also I have this display: http://www.elecfreaks.com/wiki/index.php?title=2.2S%22_TFT_LCD:_TFT01-2.2S and want to connect it directly to my board. May you help me how can I do that?

notro commented 8 years ago

That display is mentioned in the wiki: https://github.com/notro/fbtft/wiki/More-LCD-Modules#tft01-22sp Check that your kernel supports fbtft:

$ modinfo fbtft
filename:       /lib/modules/4.9.0-rc5-v7+/kernel/drivers/staging/fbtft/fbtft.ko
license:        GPL
srcversion:     3EFDADD511D35BFEE3B20A7

parm:           debug:override device debug level (ulong)

fbtft was added to linux in 4.10.

Hi notro and very thank you for reply. But I am newbie in linux and don't know how to check fbtft support? Are armbian or raspbian OS in they last version support that? If yes, I want to download and trying them on my board if it's possible!

rezaee commented 8 years ago

this is my OS information and I think there is no support for fbtft: Linux FriendlyARM 3.4.39-h3 #76 SMP PREEMPT Wed Sep 7 13:46:05 CST 2016 armv7l GNU/Linux

notro commented 8 years ago

This command will tell if you have fbtft support: modinfo fbtft_device The fbtft module can be builtin, but fbtft_device is most likely not. This will show which drivers are enabled if any:

$ zgrep CONFIG_FB_TFT /proc/config.gz
CONFIG_FB_TFT=m
<snip>

AFAICT this is the tree they build the kernel from, and it does have fbtft: https://github.com/friendlyarm/h3_lichee/tree/master/linux-3.4/drivers/staging/fbtft

I don't know which defconfig is used, but this one for instance have only 2 drivers enabled: https://github.com/friendlyarm/h3_lichee/blob/97e1a057000511abe8ed85adee6c6474398a427c/linux-3.4/arch/arm/configs/sun8iw7p1smp_defconfig#L2870

This is the resault of modinfo fbtft: modinfo: ERROR: Module fbtft not found.

But after checking the files, I found this file here: /lib/modules/3.4.39-h3/kernel/drivers/staging/fbtft

And this is the resaults of modinfo fbtft_device

And unfortunately I have no 'config.gz' :zgrep CONFIG_FB_TFT /proc/config.gz gzip: /proc/config.gz: No such file or directory

I only have 'config-3.4.39-h3.new' in /boot directory that it's an empty file I think!

rezaee commented 8 years ago

What's the meaning of these lines?

    Add to drivers/video/fbdev/Kconfig:   source "drivers/video/fbdev/fbtft/Kconfig"
    Add to drivers/video/fbdev/Makefile:  obj-y += fbtft/

I have no Kconfig and Makefile in that location!

alidaf commented 8 years ago

@rezaee Have a look at my wiki for using the SSD1322.

https://github.com/alidaf/raspberryPi/wiki/SSD1322(SPI)---notro's-fbtft-framebuffer-driver

It's a different display but I've tried to consolidate all of Notro's guides into a single page that should work for any display by changing the references to the actual module. I had to work through it all empirically and this is what worked for me in the end. There is a section that deals with those two lines but it depends on whether you use the staging location or not. I chose not to because I determined that the Kconfig and Makefile were different in different locations and this is how I ended up understanding it all.

notro commented 8 years ago

And unfortunately I have no 'config.gz'

Maybe the config is available as a module: sudo modprobe configs Or just look in the folder to see which drivers are available: /lib/modules/3.4.39-h3/kernel/drivers/staging/fbtft/

If some fbtft drivers are built into the kernel image/binary, they would show up here: /sys/bus/spi/drivers and here: /sys/module/ (a module registers a driver).

I have no Kconfig and Makefile in that location!

They were used before fbtft was added to staging, so some kernel trees have fbtft in that place.

rezaee commented 8 years ago

The result of sudo modprobe configs is modprobe: FATAL: Module configs not found. In this path: /lib/modules/3.4.39-h3/kernel/drivers/staging/fbtft/ there is only one file named fbtft_device.ko.

In this path: /sys/bus/spi/drivers there are three folders: fb_st7735s , fb_st7789s , spidev . And inside this path: /sys/module/ there are many folders that spidev is one of them!

rezaee commented 8 years ago

There are two folders in: /lib/modules : 3.4.39-h3 and 3.18.1+ In this path: /lib/modules/3.18.1+/kernel/drivers/video/fbdev/fbtft/fbtft I have fb_ili9341.c

notro commented 8 years ago

I guess your options are either to build your own kwernel with the driver enabled, or lobby to get the drivers enabled in the defconfig used to build your kernel. I looked at fb_st7735s and fb_st7789s, and they can't be made to work with your display. fbtft_device is quite flexible so it can override the init sequence, but the set_var() function sets a different value to the 0x36 register which controls mirror/flip/rotation.

rezaee commented 8 years ago

So, how can I make working my display? I am newbie in linux and don't know which solution is better! May you tell me what do I should do step by step to make it working?

notro commented 8 years ago

As I said, you need to build a new kernel with the driver enabled. If adafruit22a is the one that works with this display, you need the fb_ili9340 driver. http://lxr.free-electrons.com/source/drivers/staging/fbtft/fbtft_device.c#L338

I have no experience with nanopi. http://nanopi.io/support.html

rezaee commented 8 years ago

If I chnge my OS to armbian, will the problem be solved? As I asked in their forum, it has fbtft support in all the kernels!

rezaee commented 8 years ago

I have changed my OS to Armbian and now I have the kernel support of fbtft. So what's the next step?

I did this command: sudo modprobe fbtft_device custom name=fb_ili9341 gpios=reset:25,dc:24,led:18 speed=16000000 rotate=90 bgr=1

And the result of dmesg after that was:

[  361.544784] ---[ end trace 4484803e1c8239d6 ]---

notro commented 8 years ago

The info before end trace is important. Add this option to (maybe) get some more info: debug=7

Ok, gpio_request_one() fails with -EINVAL (-22) somewhere down the line.

Let's try and control the gpio from userspace. This should turn on backlight, run as root:

echo 18 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio18/direction
echo 1 > /sys/class/gpio/gpio18/value
rezaee commented 8 years ago

No, nothing happend!

rezaee commented 8 years ago

This is contents of /etc/modules: 

#gpio_sunxi
#w1-sunxi
#w1-gpio
#w1-therm
#sunxi-cir
fbtft_device custom name=fb_ili9341  gpios=reset:25,dc:24,led:18 speed=16000000 rotate=90 bgr=1

Maybe I must change something here?

notro commented 8 years ago

No, nothing happend!

Nothing in the kernel log?

Try removing the comment in front of gpio_sunxi. See: http://linux-sunxi.org/GPIO#Accessing_the_GPIO_pins_through_sysfs_on_sunxi-3.4

rezaee commented 8 years ago

Nothing in terminal and LCD happend. it made a folder named gpio18 in /sys/class/gpio and a file named value(beside some other files) inside it with number 1 inside the value. I did remove the front comment of gpio_sunxi and reboot my system amd try the commands again but nothing happend!

notro commented 8 years ago

it made a folder named gpio18 in /sys/class/gpio

If you can't control the gpio using this interface, then fbtft won't work. They use the same functions underneath.

rezaee commented 8 years ago

I asked about the problem in armbian forum and hope to find the solution! Very thank you for your help and so sorry I took your time!

rezaee commented 8 years ago

I think I found the problem! they are not same GPIO pins as they are in RaspberryPi3 in Nanopi-M1 (although they say this in they're advertise!!). you can see GPIO pins of nanopi-m1 here: http://wiki.friendlyarm.com/wiki/index.php/NanoPi_M1

I changed the command to this(without changing wiring): sudo modprobe fbtft_device custom name=fb_ili9341 gpios=reset:1,dc:201,led:6 speed=16000000 rotate=90 bgr=1

And the problem changed to new Error:

I am trying to find the problem, and then trying to run the LCD with your help! Thank you again in advanced.

rezaee commented 8 years ago

I checked again these codes with equal pin number in my board(6) and it worked! and turned on my LCD backlight!


echo 6 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio6/direction
echo 1 > /sys/class/gpio/gpio6/value
rezaee commented 7 years ago

I think there is a problem with fbtft code! because I can export and unexport every GPIO pins but when I try to use LCD I get this error:

fb_ili9341 spi0.0: fbtft_request_gpios: gpio_request_one('reset'=200) failed with -16
[  101.058042] fb_ili9341: probe of spi0.0 failed with error -16

I changed gpio pins but the error is the same! but testing gpio pins with export command works!

rezaee commented 7 years ago

I commented again #gpio_sunxi in /etc/modules and the problem solved. I have no errors at this time:

I tried this commands:

sudo mkdir -p /etc/X11/xorg.conf.d/
sudo wget https://gist.github.com/notro/63fc8f563b5f85010d30/raw/5e68d6c6df9471f973b3da5305e73a5017590a69/fbtft.conf -O /etc/X11/xorg.conf.d/fbtft.conf

becauseFRAMEBUFFER=/dev/fb1 startxand con2fbmap 1 1didn't work. but now the main display(HDMI) changed and went to blank screen and also TFT screen doesn't work!

And now I have no screen and I think I must reinstall my OS again! :(

notro commented 7 years ago

This means that for some reason the controller has not received the initialization sequence, or the sequence is not correct. You should get a black backlit display.

[ 78.466083] graphics fb8:

Your framebuffer is /dev/fb8

I find fbcon to be the best and least intrusive way to test if a display is working. In your case: con2fbmap 1 8

rezaee commented 7 years ago

con2fbmap 1 8 doesn't work! I tested it wit con2fbmap 1 (0to8) and non of them worked!

notro commented 7 years ago

No, I understand that. As long as the display is white it won't work. I just pointed to an easy way to test the display, instead of messing around with xorg.

rezaee commented 7 years ago

Very very thank you for your patient and helps! I shame to say but the problem was about incorrect wiring SLK and MISO! because my focus was about GPIO pins I didn't check them.

Now the display works very nice!

I have some questions: when I change the desktop with FRAMEBUFFER=/dev/fb8 startx and then want to go back to HDMI display, I use FRAMEBUFFER=/dev/fb0 startx orFRAMEBUFFER=/dev/fb1 startxbut TFT LCD freezes when display changes. why it happens and can I fix it?

Other question is How can I use touchpanel? does my display have touchpanel support? if yes, how can I activate ir?

notro commented 7 years ago

I can't help you with X, I only use it occasionally to test displays. No touchpanel support on this display.
