9 years ago @nathan-wu I have tried one whole day switching between dtoverlay=waveshare35a and dtoverlay=ads7846 in config.txt. I have follow exactly on setting up the waveshare35a as stated in the link but no luck. So sad! My touch screen just doesn't respond. I have check my debug log as attached and it seem the waceshare35a are loaded correctly. Is there anything that I set wrongly? One funny senerio that I notice from my setting is only when i issue startx command then my display will transfer from HDMI to the LCD screen. I have chance the setting from fb0 to fb1 but somehow there is nothing display on my LCD until i issue startx.

Good News!!! My luck have finally come. Thanks so much nathan.!!! :-) The problem with me is the flex cable problem. I have take out the flexcable and then put it back to try my luck and it just work perfectly... One last question from me, I have problem with cursor that flip whcih mean I pen down on left but cursor go to right. After I do a calibration, it work fine. The calibration screen ask me to save the section to /etc/X11/xorg.conf.d/99-calibration.conf to make it permanent. I have created the file but the problem is after reboot then the setting will gone. Do you encounter that ? Thank you very much. :-)

8 years ago Can someone please help me?
I also have the waveshare 3.5 spotpear and I have followed all of the advice here (thanks to everyone!).
I am using the retropie image and it boots fine, but I am still only getting the emulationstation to show on HDMI despite changing settings to FB1.
When my device boots, the screen initializes from bright white to black, but I dont see anything. If I console in and startx then I get the retropie console showing on the LCD, but still no emulationstation.
Here is the wall of text from DMESG, can anyone tell me whats going on? I really need the system to boot to LCD.

8 years ago Hello guys,
First thank you for discussing this topic and @notro for the amazing work on fbtft!
I've bought one of these chinese LCDs, named KeDei, on AliExpress.
The problem is the same of almost everyone: the screen works only wih their kernel image (which they call driver) or full raspbian image. My setup requires updated linux kernel version (4.1+) because of the other drivers I'm using and also because I want to use Ubuntu Mate, not Raspbian.
In their page, they say that the pin assignment is the same described by @sudobrew
1,17 - 3.3V
2,4 - 5V
3,5,7,8,10,12,13,15,16 - NC
6,9,14,20,25 - GND
11 - TP_IRQ (Touch Panel interrupt)
18 - LCD_RS (Instructions / Data Register Selection)
19 - LCD_SI / TP_SI (SPI data input)
21 - TP_SO (SPI data output)
22 - RST (Reset)
23 - LCD_SCK / TP_SCK (SPI clock)
24 - LCD_CS (LCD chip selection)
26 TP_CS (Touch Panel chip selection)But even after trying everything here and on other threads I'm still not able to setup the LCD by using FBTFT. Other people commented on the selling page saying that it is possible, without any other information about how. Some commented that the ILI9341 driver should work.
I've already tried also to find by lsmod and dmesg what drivers they use on the custom raspbian kernel image, but it seems that they are using another driver, still using ILI9341.
In fact, the only three posts that give some tips are listed below, although none of them have helped me in setting up the LCD correctly.
Could you please give me some advice in how to solve this? I think that if we can find the right way to setup the modprobe could lead us to a solution. Maybe something like the code @fergie4000 created for @sudobrew
modprobe flexfb width=320 height=480 regwidth=16 init=-1,0xb0,0x0,-1,0x11,-2,250,-1,0x3A,0x55,-1,0xC2,0x44,-1,0xC5,0x00,0x00,0x00,0x00,-1,0xE0,0x0F,0x1F,0x1C,0x0C,0x0F,0x08,0x48,0x98,0x37,0x0A,0x13,0x04,0x11,0x0D,0x00,-1,0xE1,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0xE2,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0x36,0x28,-1,0x11,-1,0x29,-3
modprobe fbtft_device debug=3 rotate=90 name=flexfb speed=16000000 gpios=reset:25,dc:24Thank you in advance and hope you guys could help me!

8 years ago Hello, I have a Waveshare Spotpear 3.5 Zoll Display. My R-Pi2 Runs Raspbian. if i try:
sudo modprobe flexfb width=320 height=480 regwidth=16 init=-1,0xb0,0x0,-1,0x11,-2,250,-1,0x3A,0x55,-1,0xC2,0x44,-1,0xC5,0x00,0x00,0x00,0x00,-1,0xE0,0x0F,0x1F,0x1C,0x0C,0x0F,0x08,0x48,0x98,0x37,0x0A,0x13,0x04,0x11,0x0D,0x00,-1,0xE1,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0xE2,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0x36,0x28,-1,0x11,-1,0x29,-3 sudo modprobe fbtft_device debug=3 rotate=90 name=flexfb speed=16000000 gpios=reset:25,dc:24
my display work and i can use startx, but after reboot its only white. i added in /etc/modules and /boot/cmdline.txt

8 years ago I'm new to the RPi business, running RPi 2 and clean Raspbian Jessie. Thanks to all the advices in that thread, following juhovh's blog entry http://futurice.com/blog/id-like-to-have-some-lcd-on-my-pi, notro's wiki https://github.com/notro/fbtft/wiki#make-it-permanent-debian-jessie-arch-linux-systemd and this discussion https://github.com/notro/fbtft/issues/365 I managed to make 3.5 Spotpear work.
The only issue I had was that all the colors were off (pink leaves, and stuff) and the image was fuzzy. The solution was to set speed=8000000, but I'm wondering if that's the only workaround or if there is a way to leave the speed at 16000000 while having colors right and image crisp and clear.

8 years ago I have a 3.5" Waveshare LCD as well. Currently using the manual modprobe / systemd method in rc.local to get it working. However, it would be nice to have official overlay support. Is there any progress on this part?

8 years ago Hi! I did everything that was suggested by @sudobrew and it works great (still have to see if I can get the touch working). For some reason though I have to explicitly run sudo modprobe fbtft_device debug=3 rotate=90 .... I have checked and this along with the definition for the device flextb is in my /etc/modules but it doesn't load. I also see that dmesg | grep graphics doesn't return anything whatsoever. I have the Rasbpian Jessie Lite and had to install LXDE manually. Maybe this has something to do with all this though using the image provided by the manufacturer allows me to even not load the UI and stick to the terminal which I can see on the screen without any issue (obviously touch is not working there :P). Any advice what I'm doing wrong?
@root42 will it be a problem if you share what exactly you did with rc.local?

8 years ago I tried what someone suggested for my WaveShare 4" LCD screen, here's my results.
After doing everything in proper order I am stuck on a black screen on my LCD, but apparently my touchscreen decided to be somewhat nice and work (although the controls are inverted). I have the Raspberry Pi 3 B+ so that's been my main testbed. I have been playing with the speed on line:
modprobe fbtft_device name=flexfb debug=3 rotate=0 speed=16000000 gpios=reset:25,dc:24
Any tips?

8 years ago Thanks @notro and @sudobrew followed all kinds of instructions and I am sure I am missing something simple. With Sudobrew steps to get his working works like a charm(testing) BUT cannot seem to figure out this Step 6 #Add to file /etc/modules was able to create fbtft.conf under modprob.d and such... Is there something different for the adding flexfb width=320 height=480 regwidth=16 init=-1,0xb0,0x0,-1,0x11,-2,250,-1,0x3A,0x55,-1,0xC2,0x44,-1,0xC5,0x00,0x00,0x00,0x00,-1,0xE0,0x0F,0x1F,0x1C,0x0C,0x0F,0x08,0x48,0x98,0x37,0x0A,0x13,0x04,0x11,0x0D,0x00,-1,0xE1,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0xE2,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0x36,0x28,-1,0x11,-1,0x29,-3 to a conf ...where would a person add this?
FYI using most recent Raspian/Jessie and did the rpi-update, etc.
Dooh! RTFM lol, anyways... https://github.com/notro/fbtft/issues/365 and https://github.com/notro/fbtft/wiki#make-it-permanent-debian-jessie-arch-linux-systemd All working as it should, glad to get it running on the newest raspian and now to conquer other distros.

7 years ago @jor3l my most sincere apologies...i realized that i expanded the file system before freezing the image and i'm using a 32GB micro SD - I figured uploading a 32GB file won't make any sense. I'll work on an 8GB image within the next few days and drop the download link. I attached an image of my success so you guys know it's real :D

7 years ago Got it working, this is what I did on a fresh install of Jessie:
Update firmware with:
sudo rpi-update
Enable SPI in raspi-config
sudo raspi-config
Then go to advanced, SPI and enable it
sudo nano /etc/rc.local
and add:
sudo modprobe flexfb width=320 height=480 regwidth=16 init=-1,0xb0,0x0,-1,0x11,-2,250,-1,0x3A,0x55,-1,0xC2,0x44,-1,0xC5,0x00,0x00,0x00,0x00,-1,0xE0,0x0F,0x1F,0x1C,0x0C,0x0F,0x08,0x48,0x98,0x37,0x0A,0x13,0x04,0x11,0x0D,0x00,-1,0xE1,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0xE2,0x0F,0x32,0x2E,0x0B,0x0D,0x05,0x47,0x75,0x37,0x06,0x10,0x03,0x24,0x20,0x00,-1,0x36,0x28,-1,0x11,-1,0x29,-3
sudo modprobe fbtft_device debug=3 rotate=90 name=flexfb speed=16000000 gpios=reset:25,dc:24To edit the boot process:
sudo nano /boot/cmdline.txt:
change everything to:
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait fbtft_device.custom fbtft_device.name=flexfb fbtft_device.gpios=dc:24,reset:25 fbtft_device.bgr=1 fbtft_device.speed=16000000 fbcon=map:10 fbcon=font:ProFont6x11 logo.nologo dma.dmachans=0x7f35 console=tty1 consoleblank=0 fbtft_device.fps=50 fbtft_device.rotate=0
Then run:
sudo nano /usr/share/X11/xorg.conf.d/99-fbturbo.conf:
in fbturbo change fb0 to fb1 and then run:
sudo nano /boot/config.txt
here add this line: (or search for dtoverlay and change it)
dtoverlay=ads7846,speed=500000,penirq=17,swapxy=1
then run this to add touch support:
sudo /usr/share/X11/xorg.conf.d/99-calibration.conf
add this to the 99-calibration file:
Section "InputClass"
Identifier "calibration"
MatchProduct "ADS7846 Touchscreen"
Option "Calibration" "3900 240 240 3900"
EndSection@jor3l Oh yay! congrats!

7 years ago K, this has been an incredible forum with tonnes of good info, however after trying everything here for four days straight i am still stuck!
So, at my wits-end i am here to ask for a very large favour:
Would someone with the exact same hardware as me (and who has succeeded in making it all work) be so kind as to put together a disk image for me to copy and use?
If so I'd be very grateful!
Details are as thus: I have a Raspberry Pi 3 B, a Waveshare SpotPear 3.5inch RPi LCD (A) V3 and a SanDisk 32GB microSDHC class 4 memory card. And I wish to install BerryBoot V2.0 with Raspbian Jessie (I'll add other OS's myself later)
If you can get me that far that'd amazing!
Thank you greatly in advance!

7 years ago Ok guys, been reading this post and others. But I have a problem.
I'm running a Pi 3, 32bg SD, Fresh install of RPi-35inch-LCD-Raspbian-160728.img (Raspbian). Its a premade image from waveshare.
Its boots and loads to GUI fine. Everything seems to work great. With one problem. When I use framebuffer copy to FB1 with mplayer or omxplayer I get what seems like 1 FPS. You can almost see the frame building from 1 to the next. Anyone got any ideas?

7 years ago I have the samr! Ialways thought that it is limitation of interface, and that onoy hdmi waveshare displays can go smoother. (i.e. that this class of displays is aimed for control panels na dother low-framerate applications). Will be happy to read if I am wrong and someone has solution that works smoother!

7 years ago Ok, this is my update. When using the premade waveshare image, there us actually a setting missing. In the /boot/config.txt near the bottom you have fbtft_device=waveshare35a and another after it. If you add speed=27000000 after waveshare35a you can crank up the speed.
Now, it's true you'll never get 60fps HDMI quality through your gpio to tft. This can get you to a fairly smooth and watchable experience. I don't know how to clock the fps, but I would say it's around 15fps mark.

7 years ago Has anyone been able to try the 3.5 B? Using the waveshare driver works fine on an RPi 3, including touch (just needing calibration), with the latest Raspbian image. Only issue is that the colours appear inverted :(

7 years ago Hi, I try to replace my squeeezeboxplayer using raspeberry pi 3, picore player (tinycore linux) and my waveshare 3.5. I tried all procedure I known but I still have a white screen (the HDMI is working correctly). do you have a procedure for tiny core ( kernel 4.4.39) that I could use without having X11 installed? thanks for your help

7 years ago I am using a Waveshare 3.5inch RPi LCD (A) touchscreen display on an RPi3 for this project. It has worked perfectly with Jessie Lite 2016-11-25 and rpi-update until the kernel was bumped to 4.9.y (about 21 Feb 17). After the kernel update, the display does not get loaded during boot, although the touch sensor still works. dmesg reports: "fb_ili9486: probe of spi0.0 failed with error -22" It works perfectly again after a kernel rollback to 4.4.50. Grateful for any suggestions. Dave

7 years ago Reference my post above about problems loading the Waveshare 3.5inch RPi LCD (A) touchscreen display with kernel 4.9.y. I traced it to the fact that I was trying to load the waveshare touchscreen overlay and the touchscreen driver overlay. What I did not realise is that the waveshare overlay already includes the touchscreen driver. Kernel 4.9.y seems to handle this differently to kernel 4.4.50 and throws a fatal error. I cured the problem by commenting out the duplicate touchscreen overlay. Dave

7 years ago Thanks dave, It seems that I need to create a new tft file depending on the kernel version. I will try to create a development environment with a virtual box and find a procedure to create my tft file. If some one has the procedure it would help me a lot ( I never did it). ElBoz

Hello, I have been attempting to set up a Waveshare 3.5 Spotpear , but all I have been getting is a blank bright white screen. I'm was hoping someone with a bit more experience would have more insight.
http://www.amazon.com/Waveshare-Raspberry-Resistive-Interface-Rapsberry-pi/dp/B00OZLG2YS
From the manufacturer: 1,17 - 3.3V 2,4 - 5V 3,5,7,8,10,12,13,15,16 - NC 6,9,14,20,25 - GND 11 - TP_IRQ (Touch Panel interrupt) 18 - LCD_RS (Instructions / Data Register Selection) 19 - LCD_SI / TP_SI (SPI data input) 21 - TP_SO (SPI data output) 22 - RST (Reset) 23 - LCD_SCK / TP_SCK (SPI clock) 24 - LCD_CS (LCD chip selection) 26 TP_CS (Touch Panel chip selection)
I have tried a few variations of: sudo modprobe fbtft_device custom name=fb_ili9341 speed=48000000 gpios=dc:18,reset:22 bgr=1 rotate=270 width=480 height=320
But so far all I get is the HDMI to freeze and the LCD remains bright white.
I was following this forum: https://github.com/notro/rpi-firmware/issues/6 but the solutions provided don't seem to work with this different display. I have the image provided from the manufacturer, but I would rather use the standard Raspian image.
