sainsmart 3.5 tft lcd raspberry pi made in china

SainSmart 3.5 inch TFT LCD module is a special design for Raspberry Pi for portable application. It features a 3.5 "display with 320x480 16bit color pixels and resistive touch screen. The LCD is well mated with Pi board and interface with Pi via the high speed SPI port, and support console, X windows, displaying images or video etc. It therefore Provides 4 press buttons for user defined functions.

RPi LCD needs to use a SPI interface, but in the original image file of Raspberry Pi, the displayer is driven via a HDMI port. So the original image is not applicable for RPi LCD, and you should install the LCD driver to your Pi or use the Ready-to-use image file provided by Sainsmart,click here.

Download the LCD driver and extract it to your Raspbian OS (e.g. copy the driver to your Pi by sftpor using U disk). Then run the following command via putty:

This LCD can be calibrated using a program called xinput_calibrator which is pre-installed on the offer image. However, it was not pre-installed on original Raspbian OS. So in this case, you should get and install the program manually with

After running these commands, there will be a prompt for four-point calibration shown in the LCD screen. Click the points one by one to finish the touch calibration. Then, the new calibration data will be displayed in the terminal, as shows below. Please get these data for future use.

3.5inch RPi LCD (A) and 3.5inch RPi LCD (B) are hardware compatible with each other (uses different driver), and can be mutually substituted in most cases. (A) for low cost ver. while (B) for IPS ver. with better displaying.

Key information: This device"s controller is an ILI9486, which is compatible with ILI9481. The driver for ILI9481 was already in my Raspberry Pi. Here"s what I did to make it work:

The second command sets the console (tty1) to map its output to the framebuffer (buffer 1). That"s why the parameters are 1 1. You can map any tty to the LCD.

I don"t care about the touch-screen, so I didn"t set it up. All I need this is to show me the IP address of the Raspberry Pi so I can connect through SSH. (This is an issue you may encounter only if you find your RPi connecting to WiFi where you cannot control the IP address assignments and with ridiculously short lease times.)

3.5inch RPi LCD (A) and 3.5inch RPi LCD (B) are hardware compatible with each other (uses different driver), and can be mutually substituted in most cases. (A) for low cost ver. while (B) for IPS ver. with better displaying.

Why the LCD doesn"t work with my Raspbian?To use the LCD with the Raspberry Pi official image, driver (SPI touch interface only) should be installed first. Please refer to the user manual.

However, for the first testing, you may want to use our image directly (if provided).Why the LCD still doesn"t work with the Waveshare provided image?Make sure the hardware connection is correct and connects fine.

The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact.Which power supply should I use?It is recommended to use a 5V/3A power adapter for the Raspberry Pi other than USB connection, otherwise the Pi may failed to start up because the PC"s USB port might have not enough power.

Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They"re usually some poor copies of our early hardware revisions, and comes with none support service.

STONE intelligent TFT LCD module with a Cortex-M4 32-bit CPU can be controlled by any MCU via simple Hex Instruction through the UART port. STONE TFT LCD module consists of a CPU, TFT drives, flash memory, UART port, power supply, etc. STONE also provides a basic control program and powerful design software (STONE TOOL Box).

In the previous article, I described the steps needed to install an LCD touchscreen on the Raspberry Pi. In this article, I will show you how to adjust the screen rotation of the LCD to landscape mode, and will show you how to calibrate the touchscreen pointer for optimal accuracy. Just follow the steps below to compete the process of setting up your Raspberry Pi LCD touchscreen:

1. First we need to change the setting for screen rotation in the /boot/cmdline.txt file. This setting is called fbtft_device.rotate=X. By default, this is set to X=0, which results in a portrait mode screen orientation. In order to switch the orientation to landscape mode, change fbtft_device.rotate=0 to fbtft_device.rotate=90. Enter sudo nano /boot/cmdline.txt at the command prompt. There should only be one line in this file. Go to the end of it and you will find the fbtft_device.rotate=X setting. Change the value from 0 to 90:

However, if you try to touch the screen now, you will find that the pointer movement does not correspond to your finger movement. This is because the LCD screen driver and the touchscreen controller driver have separate settings for screen rotation. We need to change the rotation of the touchscreen controller driver to match the rotation of the LCD screen driver.

After the Pi finishes rebooting, you should notice that when you move your finger across the touch screen, the pointer should follow correctly in both axes. If you are using the Raspberry Pi 2 Model B, you will need to complete the calibration steps below before the pointer follows your finger correctly (and make sure that you have enabled startx to load automatically – see step 6 in this article).

You can rotate the screen 90 degrees (as we did in this tutorial) and the power connector will be at the bottom of the screen, but you can also rotate it 270 degrees so that the power connector is at the top of the screen. To do this, simply enter fbtft_device.rotate=270 in the /boot/cmdline.txt file. Then change the DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 0 1 line in the /etc/X11/xinit/xinitrc file to DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 1 0. All you need to do is switch the values of the 0 and 1 at the end of this line.

Now that we have our LCD touchscreen up and running, the final step in the installation is the calibration of touch control. This will make the pointer much more accurate and easier to use.

This is kind of a long process, but it is well worth it if you want to get the LCD touchscreen set up properly. So if you have any trouble setting this up or have anything to say, please leave a comment below. Also, if you found this article useful, please share it with your friends!

I am sure that many people are trying to make their Raspis to display video to a nonHDMI/nonCOmposite LCD screen using its SPI port, so I hope this thread will help all of us seeking expertise with the SSD1289 controller.

LCD Screens with SSD1289 controller sold in eBay for less than 10$. They include a touch screen film and an SD card reader. For the video, the screen needs 16pins for 16bits of data + 4-5 controll pins.

The problem with pi, is that its SPI does not offer that many GPIOs to "talk" to the screen using parallel mode. Although SSD1289 controller supports serial mode/interface, the LCD screen does not offer this capability. But this guy here: http://spritesmods.com/?art=spitft&page=1 made a nice schematic using a counter and 3 shift registers to get a parallel interface out of a serial. He also gives a kernel patch to enable the ssd1289 driver to use his hardware implementation but unfortunately he made it for Carambola linux platform. His patches include an ssd1289 driver he made from scratch, KConfig patch for adding his shift-registers hardware support to kernel and modifications to the SPI module of carambola.

I do not own a Carambola and I am trying to build the RaspberryPi"s kernel using the patches Spritesmods.com provides after modifying them to match Raspberry"s sources.

Carambola"s patch includes patch for drivers/video/Kconfig and drivers/video/Makefile that I think can be applied easily to Raspi. Then the menuconfig will display an option to select native I/O or the shift registered hardware version.

The difficult part here is to enable the ssd1289 driver from the SPI module (arch/arm/mach-bcm2708/bcm2708.c). I have made some attempts to make SPI "see" the ssd1289 without success.

I used kernel compilation on the Raspi (built once on a usb stick and execute make after each time to only build the changed file) Crosscompiling made the ssd1289 driver to throw a compilation error (I can"t remember the error message).

very nice and helpful entry. I am still at work (16:18 GR time), I will try to post my work on bcm2708.c when I get home later today. What I remember is that only seting the driver name is not enough, I had added includes and defines for the GPIO pins (mosi, miso, reset) (I tried to understand what the Carambola SPI driver did and move the logic to Raspberry).

Just a tip for anyone reading this post. If you compile locally (not cross-compiling) and you spend 6-9 hours to get your first build, backup your build. I had a lot of corrupted filesystem errors and had to re-write my SD card making the kernel build to be lost. I find it easy to mount a usb stick and make the build ON the stick.

I had added includes and defines for the GPIO pins (mosi, miso, reset) (I tried to understand what the Carambola SPI driver did and move the logic to Raspberry)

As I see it, this is not needed. The PI already has SPI available on the P1 header. And there is a SPI driver, but it has to be removed from the blacklist:

However, I connected 3 LEDs to MOSI, SCKL, CS0 of raspi set default framebuffer to dev/fb01 and tried to write something to it and the LEDs were blinking. I assume that commands are writen to SPI through the ssd1289 driver correctly.

My screen is slightly different than the one spritesmods uses. It does not provide a pinout diagram, it has the 40pin connector but does not for e.g. contains a BL_CNT as spritesmodes schema shows.

Anyway, I will try to debug the SPI and the schematic and will post when I have more news. I am trying to find a way to read the data sent from raspi"s SPI to check if the commands for screen init and command data are correct.

also it has a touchscreen...would that be a problem? i am looking forward to building a completely portable Raspberry Pi computer and have it with a minamal footprint that enables me to use it in my hands....

As Les said this cannot be done directly but in this post we try to do this using 4 ICs (a counter and three registers) that would take serial input from raspberry"s SPI and transforming to 24bits for the Screen. If you read my first post you will see another guy implemented that for another linux device the carambola.

So basically the display i posted as the link would work, as it is almost identical to the spritesmods.com one right?? Have you been able to display anything on your display? and would the touch module also work fine with the Pi?

I tried to debug the circuit by counting the voltages of the ICs / and connected 20 LEDs on the ICs data pins and I figured out that the 4094s does not change state while on SPI0 (/dev/fb1). If I change the data input of the circuit to SPI2 (/dev/spidev0.1) - this can be done by simply moving the circuit"s CS input from Raspberry"s CS0 to CS1 on its SPI- and send random data, the CIs respond, and change state (LEDs turn on / off).

It looks like that Raspi"s SPI resets the 4020 before it counts 32 cycles. It seems that an active low comes out of Raspi"s CS on each cycle (which resets the counter).

when you connect the raspi to the power SPI /CS goes HIGH this causes reset of 4020 and its Q5 goes LOW. It is not correct situation for the LCD. You can"t keep it"s /CS LOW forever.

When you write 4 bytes to SPI it"s /CS goes LOW then 4020 counts 32 cycles and its Q5 goes to HIGH then after some little time SPI"s /CS goes HIGH and it causes reset of 4020 so Q5 goes LOW again.

I wish I had an oscilloscope!!! By the way nice pics. Are they taken using real data from the ssd driver? Did you install the driver as this post explains and read these inputs? And if yes, why SPI is always low?

As I didnt have an inverted I tried to make two raspi GPIO pins to simulate an inverter: (if PIN1==low PIN2 set HIGH else PIN2 set LOW) but it did not work either. I assume raspberrypi wiringpi is not fast enough to simulate a real NOT gate.

Also my screen does not have any pinout printing on it, it contains 40 pins without a pinout table or something. I will try to find and buy the screen sprite modes uses.

I"m a tad concerned by the trouble you"ve all been having. Obvious question, but has anyone tried setting the SPI pins on the PI to GPIO mode, and driving them directly (clock included), thus slowing the whole cycle down, and watching what happens.

3. In static int ssd1289_spi_write(struct ssd1289 *item, unsigned short value, unsigned int isdata) you should send 4 bytes not3 like in the SpriteMods"s patch.

It is a bit different than the one valdodov uses (it has 40 pins, incudes an SD card slot, etc). Also my screen does not have the pinout printed on the back. I tried to contact the guy from ebay so he may could send me / hep me with the pinout but without success. I assumed that the pinout would be the same as SSD1289 datasheet or the 40pins schematics I ve found on the internet.
