※Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule.

ER-OLEDM032-1B is the 256x64 blue pixels OLED display with adaptor board that simplifies your design,diagonal is only 3.2 inch.The controller ic SSD1322, communicates via 6800/8080 8-bit parallel and 3-wire/4-wire serial interface. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast,extremely wide viewing angle and extremely operating temperature.Please refer to below interfacing document for how to switch to different interface. The default interface is 8-bit 8080 parallel.

It"s easily controlled by MCU such as 8051,PIC,AVR,ARDUINO,ARM and Raspberry Pi.It can be used in any embedded systems,industrial device,security,medical and hand-held device.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" We prepared the interfacing documents,libraries and examples for arduino due,mega 2560,uno,nano and for raspberry pi or raspberry pi zero.For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and Development Kit at the bottom of this page.

We have an alternative solution for Raspberry Pi compatible HDMI display; the 3.2 inch Resistive TFT Touch Screen Display, which uses SPI Protocol (serial peripheral interface) to communicate with the main processor. It can be mounted directly to the GPIO pins and it doesn’t require any external power source. In here we have detailed explanation on how to install LCD drivers in a custom Raspbian image. The standard version of Raspbian does not include drivers for LCD touchscreens, so we will have to install and configure them manually.

After that, configure the fbturbo video driverto divert the RPi display out from HDMI bus to the SPI bus. Enter the below given code in command prompt,

After a reboot there wont be any output on HDMI screen. To input further commands in terminal window we will have to use the SSH method for remote connection with the Raspberry Pi board.Click here for details on how to setup the remote connection.

Currently, the kernel module for Raspberry Pi’s Broadcom processor snd-bcm2835 is set to load automatically. Add this code below the snd-bcm2835 line to support fbtft_device and ads7846_device modules:

Note:“Starting from fb_ili9340 to the end of the line, ‘-3′, should be entered ALL IN ONE LINE !!!” fbtft_device denotes the kernel module of LCD and ads7846_device denotes the kernel module of touchscreen. ads7846 is the touchscreen controller chip used in the Waveshare 3.2″ LCD and many other touchscreen displays.

Now we need to edit the /boot/cmdline.txt file, which is the RPi’s boot-up configuration file. Use the following code in command prompt to open the file.

I assume you can split the LCD board from the Arduino shield at the 40 pin connector. For compactness, we"ll want to discard the shield if we can, so please confirm that you can split the display off the shield.

2) 50mm on a side is tight for a 40 pin connector, but I think we can pull it off. To fit both connectors in, we"ll need to have the 40 pin connector overhang the Rasperry Pi SD card by about 7 or 8 mm. My thought is the display will sit directly above this, so that should provide a nice fit with the SD just protruding from a slot in a case (I assume you have your own ideas in the area of casing). This approach won"t fit in a standard Pi case, but I"m struggling to imagine an of the shelf case that would accomodate the LCD anyway.

3) To minimise thickness, I suggest we use what is called a bottom entry surface mount 40 pin connector. This will allow the LCD display to sit directly on top of the adapter board. The whole assembly will be no more than the height of the yellow audio connector on the Pi plus the thickness of the LCD display itself. In other words, the adapter we create will nestle down beside the audio connector and itself add no height to the assembly at all. Let me know if you have trouble visualising it and I"ll send you a sketch.

4) The Pi has limited IO. 17 GPIO"s to be exact. To talk to the LCD display in 8 bit mode requires 12 signals, maybe 11 if we"re lucky. To talk to the touch screen we need another 4. That"s 15 or 16 GPIO"s used up. This does not leave much room for other functions.

6) There may be room add some "insurance" onto the PCB design in the form of a programmable logic chip like this: https://github.com/Guzunty/Pi/wiki (Disclosure: I curate the Guzunty GitHub site). The actual chip we would use would be physically much smaller than the one shown on the Guzunty web page, the one shown there is designed for easy home assembly. What I suggest is that we design the board so that we don"t have to populate the place for the chip unless we find that video performance isn"t good enough, or we are short of inputs etc. If necessary, the logic chip can then be soldered in later and programmed to accelerate the video display or provide some IO expansion or whatever. That is why I call it "insurance". If we find we never need it then great, it didn"t cost us anything (unlike real world insurance :-) ). Just a set of pads on the PCB.

I am an experienced C, C++, Java developer. I"ve built MAME from source on the Pi but I have never dug in under the hood. We may have to get on some of the MAME forums to enlist some help in this area. There are three areas we need to address: input/output, video and sound. The first has been done, I just need to go find it again. I"m not aware of any work done to stream MAME video to alternate display devices, but it can be done, I"m sure.

That leaves sound. What did you have in mind here? MAME without sound would be like apple pie without icecream. :-) Pi has the yellow headphone connector. I haven"t listened to it, but I"ve heard its not great compared to the digital audio the Pi produces through the HDMI connector. Taking sound from the HDMI connector would (IMHO) be rather clumsy. One less obvious (and more ambitious) alternative is to add J5 onto our PCB and create traces for an audio codec and a small audio amplifier. Some of the pins on J5 can carry an I2S digital audio stream.

The TFT isn’t ‘plug & play’ with the Raspberry, a patch has to be applied to the kernel to be able to interface via SPI with the ST7735R controller chip on the TFT. Once working, the display will act as a framebuffer device.

As it takes over three hours to compile the kernel on the PI, I will show how to cross compile from another Linux PC. In my case, it is Ubuntu 12.10 running within VMWare on a Windows 7 Quad core PC. Kernel compile time is 15 mins.

-Copy config from the Raspberry Pi to the Ubuntu box using SCP. Replace ‘raspberrypi’ below with the IP address of your Raspberry Pi if hostname lookup fails.

If you are planning on displaying the console on the TFT, then enabling these options in .config will allow you to change the font size and rotate the display later on.

To enable parallel processing for a faster compile. If you have a dual core processor add -j 3 to the end of the command below. If you have quad core, add -j 6

The last step below is to SCP the files from from Ubuntu to the Raspberry Pi. If you have trouble SCPing into your Ubuntu box you may need to install open SSH on Ubuntu with sudo apt-get install openssh-server. This step also copies the files from my home folder ‘mark’… yours would be different.

If you build the st7735 driver pair as built-in, add these options to the end of the line in /boot/cmdline.txt. This will display the console on the TFT.

Since the Pi doesn"t have a 3.2 inch display, at the very least a clue to where you got it from would help. Asking those who supplied it would probably be a better idea than posting here. A lot of these things have propitiatory drivers built into their images and nobody here could help anyway.

It won"t work if you type in capitals. If its a propitiatory image, theres no guarantee any standard Raspbian stuff will work. It may have started life as Raspbian but god knows what has happened to it since. If you did update it, it might kill the display anyway.

Alas I didn"t achieve what I wanted, but I feel I have made SOME progress in that although I can"t swap back to the LCD screen, I can at least SSH into it and re-establish the HDMI output if needed.

2: i can use the raspbian that came with the lcd but the pics are to big for the screen and nothing can fix it i tryed the normal stuff it seems to spill off the right and bottom even editing boot/config.txt does nothing at all ;/

You just need to know that the names given on the piece of paper are wrong, and just log in as pi. Then you can muck about and SUDO things as needed.

and what i was saying with the ssh is YES i can ssh into the one where the lcd works BUT ONLY with passwords as it will NOT accept keys period i have done every walk though change permissions as pi / raspberry / root / took owership (made the key AS that user on that pi and still nothing) it just says " server has rejected our key"

the only file i can edit that does anything is in root where i can force the screen size however if i change it AT ALL the sceen just go"s black in some areas the the pictures turns to fuzzy nothing OR i lose a chunk of screen (say i use 200,200 i will just blank out the left over area (and still nothing fits )

so i"m not allowed to use it and thus i need to fix it another way (pref ssh ) but seeing how ssh refuses to work on the (lcd firmware) id prefer to just use a fresh rasbian install and put the lcd drivers in to it

Somewhere in all of that you will see white numbers appear on the LCD. The are the character height and width of the window. I think the biggest for the display is about 40 x 16.

LCD4-SYS-DISPLAY but sadly it seems no matter what i enter nothing changes it just reboots and is "stuck" i can post some pictures if you need them but they would all be almost identical
