sainsmart 3.2 tft lcd display raspberry pi 2 factory

I have a older shield for the mega, want to make it work the the due. how can i do this, mine the display is soldered on the shield, and there are surfacemount resisters, i can get to the resisters with a soldering iron if need be.

I"be been using both the CTE class and the UTFT class on a Digix and both are flawless, The CTE shield and class being noticeably faster compared to the class Mr Karlsen wrote last year. Screamer fast)

Apparently when he rewrote the class to better encompass the Arm Avr and Pic processors he changed a substantial amount of code. I have had.. some code for the class written early last year and the speed differences are substantial... One of the Very few times I"ve "Donated" to a project and really got my $0.50"s worth.. The Manuals... "Manuals"? who ever heard of actually supplying manuals with Arduino code...? The manuals are an encyclopedia compared to the Arduino Manuals? and are actually useful.

If you use Mr Karlsen"s code a donation would be a sign that you appreciate what he has done and how much it"s made your own work easier. FWIW I own 3, 3.2" displays (5 if you cound 2, 4D Systems 3.2" displays and an Itead 4.3 which was junk defective out of the box (randomly shows a silver screen and the postage to return it is more than the "thing" is worth) and a CTE 4.3 which is beautiful.

The data pins are routed to PC1-8 (lower 8 bit) and PC12-19 (higher 8 bit), so you probably need to shift your lower 8 bit to the right<<1, and higher 8 bit to the right <<12, and then you can strobe the WR pin. So you will need 3 arduino command for one WR strobe.

Please help me. I have Arduino DUE + 7" SSD1963 LCD 800 x 480 + shield for arduino due. I downloaded the UTFT library and try the example but the display did not run. I tried with Mega 2560 + shield for mega 2560 the same result.

You could elaborate where you downloaded the UTFT library from? If you downloaded it from this thread, it is a modified version with unofficial modifications.

Your best bet is download the official version of the UTFT suite of libraries from the author"s own website. Electronics - Henning Karlsen If these are not the libraries you already have, delete the ones you have now!!

Did you read the documentation for your TFT shield? Did you change the example sketches to use the pins of YOUR shield? Did you use an external AC/DC power supply since 7" panels require more power than USB can supply? Did you try google and see the 5 or 6 different threads on this forum where I have already made these suggestion many times before.....

I tried many times with UTFT library from http://www.henningkarlsen.com without any result. The pins are configured for my LCD type and an external 9V/3A power supply is plugged in. I red a lot of threads and I am thinking about purchasing a new one. I think this one i damaged or defective one.

I needed a display for a new project that I am working on and saw that the 3.5 RPI Display Board was on sale and decided to pick one up. I"ve previously used mini OLED displays before, but they"re pretty limited by its size and the colors that it can display. This is a 480x320 resolution device that is designed to affix right onto the Raspberry Pi (RPi) GPIO pins. The installation is simple as you"d imagine:

For the project I had in mind, I do not need a fancy GUI nor the use of the touch controller. The display will be used to show console statistics and accessing the device using SSH.

I am using a vanilla Raspbian lite and no additional drivers were required to get this working. All we need to do is configure some boot scripts and introduce some new configuration files. It"s possible to do this manually, but thankfully LCD-Show automates the process for us.

It would have been nice if I could have mirrored the HDMI output and the LCD panel at the same time, but I could not figure out how to do this or if it was possible at all.

Secondly, it allows a remote user to connect to an existing SSH session. If I were to kick off a Tmux session on user log on, I am be able to connect to the same session from a remote computer. This means that I should connect to the session that is being shown on the physical display and interact with it as if I was seated in front of it.

The LCD is compatible with both the Raspberry PI Zero and its big brother variants so these same instructions can be applied to get them both running.

I have the same LCD as you do. i was wondering if you could help me with the pinout of the LCD… valdodov has a different lcd and his schematic doesn’t transfer well to the one you have i think. is there a schematic that you could post or tell me where BL_CNT is connected from the 4094s to the LCD?

Thanks for the schematic, I will try and see if this works. if not, its probably some issue with the kernel. Also, if it is due to the kernel… was the kernel files just supposed to be copy pasted into the specific folders? was i supposed to enter anything in the command-line/terminal to get the display to start working?Just need to overwrite what is on your SD card.

the Spi (MOSI) is buffering 32 bits (when the strobe is off) then the SPI (MOSI) waits for 32 spi cycles (When strobe is on ) . Am i understanding correctly .

That’s great and all, but is there a way to push raw image data (bitmap images, video, etc) to this display without making it an active tty/X display? Something that can run headless and have data pushed to it from a remote ssh session, cron job, etc?

I’m thinking of a Python or C library, or better yet an optimized binary that you can pipe the raw data to from another process to send it to the screen…yes to all the above. You just need to write to the framebuffer

Where did you find the pin out for the sainsmart touch screen? We were looking at the following data sheet and it has different pin assignments. Please help us clear up this confusion. Thank you!!the display in your datasheet uses ILI9325 driver chip for the display.

If you cant display the image or you get the same error, I would recheck the wiring. Are you using a breadboard?No /dev/fb1 is not present. We are using a breadboard and just rechecked all of the wiring. The wiring looks good, but we are missing the filter capacitors (can’t get them till tomorrow) would that be the issue? It looks like a few people had this same issue but there is no definitive solution. What exactly is error -22?

We were following the instructions on github/notro/fbtft/wiki but I think I just realized that that’s a different method. So in order to install the kernel/modules should we use the compiled files on Voldadov’s site? If so, how do I copy those drivers? I extracted them to the desktop then did:

Finally got it working! (Sort of) Must have had a few dead rails on my breadboard because I purchased an new breadboard, and lo and behold, our screen works. We can see the boot information and there are no errors, but it stops at a blinking command prompt, but I cannot type with the keyboard, and it does not boot into the desktop. So we’re kind of stuck at a blank command prompt. Is there any code I can edit to make it boot into the desktop? Or is there any way to make the keyboard work?Do you have the keyboard directly connected to the Pi? Or are you accessing the Pi via SSH from another PC?

sudo mplayer -vo fbdev2:/dev/fb1 -x 128 -y 160 -zoom fileWe have the keyboard directly conneected to the pi. Should we be using SSH? And we can get it to work by deleting the

I am working for several months with the Raspberry and I also know a few experminete performed. Well me too interested this project. I myself already so bought a 3.2 “touchscreen, but I dunno exactly how to wire the. Could you maybe make a wiring diagram. That would be very nice.For example, with http://fritzing.org/

We are following your circuit for interfacing the raspberry pi with touch screen. We have currently wired on a breadboard and currently working on a better consistent solution like having it on a PCB.

hae the boot screen with white lines ….. by starting xbmc screen gets smoothy to white and finish….. think its wrong screen size… how can i set the resolution for all in to 320×240?hm…. can see the boot rows…. sometimes…….

sometimes with blue stripes…. sometimes not all letters only a small stripe….. and agter getting message ???52×21??? screen goes slowly white……I think……. i have killed the display :-p … ok next one…

-What driver?I am using the same chips and TFT as you are using. The driver i am using is Raspbian. I am using a breadboard but i have checked the circuit multiple times using a multimeter to confirm the connections so i am not sure if that is an issue.

Thank you for your help. I found a small connection issues with one of the ribbon cables i was using from the raspberry to the breadboard. Now that it is fixed everything works great without any problems. Thanks.

I have a question about kernel: I install the Rpi version 2014-06-20-wheezy-raspbian, kernel version 3.12.25+ #700 after upgrade, but after apply valdodov, kernel come back to 3.6.11 #41 …

Thanks for the Kernel but on my Pi is nothing to go the Display is not working. I have the Sainsmart 3,2 TFT with the Modul that is in the Video (selfmade) but i find no error in my circuit board it is with 3 74HC4094 and 1 74HC4040 . ? Is there a Kernel that Support this Version with no updates.?

anyone a idea where this vertical flashing lines come from?It has been awhile since I have looked at this version of the display with the above SPI interface.

You can also try and force the 4040 to go faster my connecting it to 5vi found the issue…. above GND is a Pin named “VCC” – it was not connected (and looking at your schematics, it didn’t look like it has to be connected to 5v)
