It doesn't say which LCD controller the display uses on that page.
I see the display comes with an image. Isn't that good enough? If they use FBTFT on that image, see if you find a module starting with _fb_ in /sys/module_
LCD shields for the Pi is popping up all over the place now. Seven months ago it was only a handful: https://github.com/notro/fbtft/wiki/Raspberry-Pi-Display-shield-comparison
I have also the old one, but wasnt succesfull getting it to work - to be honest, havnt spent a lot of time. Is it a ssd1289, at least the driver is named that way, probably I have used wrong kernel parameters for the module.
BTW, this is what the manufacturer supplied:
PIN NO. SYMBOL DESCRIPTION 1, 17 3.3V Power positive (3.3V power input) 2, 4 5V Power positive (5V power input) 11 TP_IRQ Touch screen interrupt, low level while the touch screen detects touching 12 KEY1 Key 13 KEY2 Key 15 KEY3 Key 19 LCD_SI/TP_SI SPI data input of LCD/touch screen 21 LCD_SO/TP_SO SPI data output of LCD/touch screen 23 LCD_SCK/TP_SCK SPI clock of LCD/touch screen 24 LCD_CS LCD chip selection, low active 26 TP_CS Touch screen chip selection, low active
Any help whould be appreciated. Thx, Florian
Since there is no DC/RS pin I assume it's using the 3-wire SPI mode, which on this controller means 9-bit SPI. From the top of my head:
sudo modprobe fbtft_device custom name=fb_ssd1289 speed=8000000 buswidth=9 width=XX height=XX
If the width/height of your display differs from 240x320, you have to provide your own init= sequence. The default one assumes this. Panels differ, so you might have to provide one anyway.
Didnt work, but I have done a little more research on these piece of hardware. It is an exact copy of valdodov's circuit and was delivered with the precompiled kernel/modules/configs from his web site.
There was already a ticket in Mai #115 on that matter, is there any chance to get it working ?
Thx, Florian
I can't get it to work either. Unfortunately, my display didn't come with an image.
Cheers.
It is an exact copy of valdodov's circuit ... is there any chance to get it working ?
No plans to support that circuit.
I found a custom raspberrian image for this display on a dutch website here: http://eckstein-shop.de/Plug-and-Play-32-inch-Touch-Screen-TFT-LCD-for-Raspberry-Pi-A-/-B-/-B-_1 NOTE: the archive is password protected (dick move). I've posted on their site to ask for the password. UPDATE: password for archive is "eckstein", will now see if this is the image we seek.
I also emailed the manufacturer, will post again if either of these leads work.
Manufacturer refuses to offer any help:
"It seems like the picture is ours.........
If the reseller bought the LCD from us then resell to you, then they must have the CD, as we have CD for each of this LCD screen. We don't have links for download, all the contents for the LCD are contained in the CD, it should be the resellers problems who did not send the user guide CD to the package.
You can image that if all of the reseller, to whom we have already provided the CD for the products, then they don't send it to customers, then how can we provide the direct services to customers?
Thank you for your understand.

Any news on this topic? I am currently also using one of those displays with the image supplied by eckstein. Although this seems to work fine so far, I would prefer to switch to a more open solution (for more recent kernels, etc).
I copied configuration of the module from that image. It should work but I haven't had the time to try it yet:
I also have Waveshare 3.2inch RPi LCD (B) V3 connected to Raspberry Pi Model B+ http://www.wvshare.com/product/3.2inch-RPi-LCD-B.htm http://www.amazon.com/Waveshare-Raspberry-Resistive-Interface-Rapsberry-pi/dp/B00N0SNVQE
I have found that the initialization string is very close to fb_ili9340 driver, so after few days of testing I found this configuration is pretty stable
1) Use FBTFT drivers built into the kernel
sudo REPO_URI=https://github.com/notro/rpi-firmware BRANCH=builtin rpi-update
sudo reboot
2) After rebooting, check that SPI was created
# dmesg | grep spi

4) To enable console on boot add to /boot/cmdline.txt

5) Also may be useful to add

I've managed to make this work. But has anyone figured out how to make Waveshare 3.2inch RPi LCD work in GUI (startx)? As long as I have a HDMI connected I can see the GUI from an extra screen.
you want to use them separately or simultaneously? maybe fbcp will help https://github.com/notro/fbtft-spindle/wiki/FBTFT-image#fbcp---framebuffer-copy
I treid fbcp. It copies the big screen (connected through HDMI) which is hanging, into the Waveshare 3.2inch RPi LCD (B) V3. So both screens seems like they hang.
But this is how it's to me.
Normally after making the Waveshare 3.2inch RPi LCD (B) V3-screen work, raspbian runs fine with the little screen. As I only boot into console/terminal. But if I'm going to GUI (startx) the tiny screen hangs.
While booting with an extra screen connected on the HDMI-plug. The extra screen hangs, and the tiny one works fine and mentioned.
When I do the "startx"-command, the HDMI-plugged screen is the one working good in GUI. While the tiny screen hangs.
I wanted to make it so that the tiny screen is standalone and possible to run into GUI (startx). I see the use of fbcp, but it's not for my use.
What I want to do, is to make the tiny screen run fine in GUI (startx). And I'm wondering if you have managed to do that :)
Than you for your time :)
I have a 3.2inch RPi LCD (B) V3 from waveshare. It came with their DVK512 which includes a CD with an SD image that makes X work on the LCD. Image is Linux raspberrypi 3.12.25+ with (I guess) their custom command: LCD32-SYS-SHOW-V3 which reboots with x on LCD.
You say the Image is Linux raspberrypi 3.12.25+, so not raspbian customized?
Hmm, do you by any chance have the possibility to upload this anywhere?
It is too big to upload... It must be available somewhere already. Check this out : http://www.raspberrypi.org/forums/viewtopic.php?f=28&t=89127
Thank you! Found this link which have .pdf and the software. So no need for downloading a whole new image into the rasp. pi. Will try this when I have time.
I got my Waveshare 3.2inch LCD working great using the instructions above provided by "imaginal". I now want to be able to turn off the backlight. Has anyone been able to do this? Is the functionality supported?
Does anyone know how can i turn off the backlight? for the Waveshare 3.2inch LCD
I have been googling everywhere and i cant seem to find it...
Notro nevermind im going to buy adafruits one and return this chinese one... Thanks :)
Hiya all.
I have a WaveShare SpotPear V4 LCD with a Raspbian image (unfortunately with loads of excess baggage included, the image is just over 4GB).
I should be able to get it onto the web shortly (give me a few days), I also plan on stripping it back to a very minimal Raspbian with OpenBox and a few utils such as SSH if anybody is interested?

@lunarcms I am very interested, I received my waveshare today and need to use it for first test of my pi b+, I do not have an hdmi monitor.
3.5in rpi LCD (A). Current name of image on the disk: LCD35-14120 So from the instructions on the disc. I believe it is rasbian with display drivers. Now how bad is the bloatware?
I need to format the sd-noob card ( only 4gig card I have) Is it worth losing the noob software and images?
Could someone look into why drivers built into the kernel is the only way that seems to work?
would love to make Kodi 14.1 work with this display have tried different configs but all give me some kind of error ie-can't find file, can't find dir, debends on xbmc-deb, no make etc, any help would be great.
Mike
Okay, I've fiddled around with this stuff. In /etc/modules I have: fbtft_device custom name=fb_ili9340 speed=48000000 gpios=dc:22,reset:27 bgr=1 rotate=270
I added to /boot/cmdline.txt: fbcon=map:10 fbcon=font:ProFont6x11 logo.nologo
The console on startup works just fine, but for some reason, I can't find out how to launch framebuffer applications on the tft display.
I tried su -l pi -c "env FRAMEBUFFER=/dev/fb1 startx &"
, but that resulted in the tft display being cleared and X starting on the HDMI display.
Any ideas?

"I should be able to get it onto the web shortly (give me a few days), I also plan on stripping it back to a very minimal Raspbian with OpenBox and a few utils such as SSH if anybody is interested?"
@lunarcms, that would be wonderful. I had a pretty rough time with setting up a 4" Waveshare display because I only had a 4 GB Micro SD and the manufacturer probably had expended all the available space. Have you set something like that up? I couldn't find drivers or a kernel to make the screen work. Doesn't feel right to have an outdated Raspbian (well, the GUI) with a load of junk installed.
EDIT: Wait, by "V4" did you mean 4 inch or is that unrelated, haha?
That would be super. I would like to use this for a touch screen tool, so a simple distro would help!

ordered this: got the waveshare 3.2 inch http://www.amazon.com/gp/product/B00LGOS00G/ref=oh_aui_detailpage_o06_s01?ie=UTF8&psc=1 amazon hosts image here https://s3.amazonaws.com/lcd32/LCD32-CN.rar

I recently bought the lcd from this site "https://www.crazypi.com/raspberry-pi-products/Raspberry-Pi-Accessories/32-TOUCH-DISPLAY-RASPBERRY-PI".I got a DVD which contain the image file.I am using a B+ board.I burned the image to sd card.But when i power on the board by plugging the display,LCD is completly blank,no backlight ?Please help.I connected a keyboard with raspberry pi through USB port.When i pressed caps lock in keyboard the caps lock light glowed in keyboard.So i think Pi is booting correctly.But LCD is blank.How to check wheather the problem is with SD card,Pi or LCD ?????
Please contact the seller. They know their display and image.
Maybe the images for the Odroid which supports the LCD can help?

Any one has success with Waveshare 3.2inch V4 on Raspberry Pi 2 Model B? I tried with image on CD came with it, but no success. It just show Multi Colored Big Block on the screen that cover 90% of screen. And there no response from raspi at all.
Also Tried with Fresh new image of Raspbian 2015-2-16 and running: sudo REPO_URI=https://github.com/notro/rpi-firmware BRANCH=builtin rpi-update sudo reboot
Get exact same Multi Colored block on initial screen, same as I get with Image from CD.
Any help?
sounds like it is booting in hdmi mode. try pluging a monitor in the hdmi port and rebooting.

Yes, I did that. It was connected with Hdmi, as it was showing that on monitor. Noticed this is the very first thing usually show on monitor for few second befit continue with boot. But not it look like stuck on intial screen and won't continue.

Same problem here , tried several displays and images. after reboot the rasp freezes multicolor on main hdmi output white screen on the tft...
anyone ?

Highly appreciate if possible to have script or something to setup on my own Linux image rather than using image come with LCD.

Have found another TT i'm now setting up...
http://www.circuitbasics.com/setup-lcd-touchscreen-raspberry-pi/

Just check the cable on the back side of LCD display....My display wasn't working....After i correctly plugged in the ribbon cable to the board it worked fine....Hope this will help...
Anyone got it working with splash screen on boot? I tried to follow instruction from https://github.com/notro/fbtft/wiki/Bootsplash
But seems something missing as it does not work for me. Any help?
initramfs is done differently with the current Device Tree kernels. I haven't had time to look into it. There's something in this thread: http://www.raspberrypi.org/forums/viewtopic.php?p=685709&sid=61c7334eb300ad23c03fb28f94e37d7c#p685709 If you make it work and have the time, please update the fbtft bootsplash wiki page.
Notro, I'm not very much experience with RPi, new learner here. If you can point me to some source I can definitely try. Above link has some info but not able to make out much sense out of it as I'm not even sure what initramfs does and why it used other than is loaded initially during boot sequence.
Any pointer would be helpful for me to look for solution.
On Side note: I tried to do BRANH=builtin rpi-update expecting with get kernel with built into it and that might help, but that also got my LCD screen to go back to white blank and when check on hdmi output it stuck with initial Rainbow screen and no progress with boot.
BRANCH=builtin is deprecated. I haven't got time to make it anymore. As soon as we get a SPI DMA driver in the official kernel release, I will stop releasing the BRANCH=master kernel also.
initramfs is loaded very early in the boot process, and at that point you can load the fbtft drivers and plymouth will also start if enabled.
Divide your work into steps, first find out how to make and load an initramfs, then when it works, start filling it. I use google when I don't know how to do something. Usually I get multiple takes an the problem.
I bought the v4 version (http://www.aliexpress.com/item/3-2-LCD-Touch-Screen-Display-Monitor-Case-Heatsinks-for-Raspberry-Pi-B/32235705777.html) and managed to get it working on a pi1 model B with raspbian installed. Does anyone have a GPIO script to control the buttons ? Basically i want to turn the display on/off by pressing a button. I found this: http://www.circuitbasics.com/raspberry-pi-touchscreen-calibration-screen-rotation/#comment-145 but i cant find any command to turn the screen on/off to use it.
Hi when doin the 1st step Touchscreen Setup and Configuration
I get it come up but its empty nothing in it atall
I followed these steps but on reboot it just hung on the following screen
rebuilding rasbian now all I know about my screen is as it says on back 4INCH RPI LCD(A) WAVESHARE SPOTPARE
I kbow the screen works with the supplied image but don't wanna use theres cus i wanna use mine so i can chose to boot rasp or openelec
Is there any support for this display coming up ? http://www.wvshare.com/product/3.2inch-RPi-LCD-B.htm I have btw the previous version (without the B). Erik
