Senior Management and Product Marketing teams all now want TFT displays on their products, showing content rich user interfaces full of colour and graphics.

Monochrome displays are slowly going out of style. Not only have prices for colour TFTs now dropped to levels on par with STN displays, but TFTs also offer more options with respect to the display of information.

So, why do many engineers still hesitate when it comes to adding colour to their products? One reason is integrating conventional TFTs into existing systems is usually a complex process. After all, colour displays require more data and hence more memory at a higher rate than monochrome displays. Depending on the display’s level of integration, data must often be continuously updated. Basically, a high-performance processor becomes necessary…………..or does it?

IDS have introduced a range of UART TFTs from AMPIRE, a manufacturer specializing in displays for industrial applications,and for their longevity of product. These TFTs have been developed as an intelligent display solution that unburdens the main processor and is easier to drive at the same time. With integrated µC logic and memory, as well as a UART interface, these intelligent displays offer a nearly complete plug-and-play solution. Our small to medium-sized UART TFT platforms are integrated with touch screen, driving electronics and backlight drivers.

The modules can be configured as UART, RS-232 or USB versions and feature a wide input voltage range from 4.6VDC to 26VDC. With a brightness of up to 500cd/m² and resolution ranging from VGA to WVGA, the displays are well suited for many different applications. The modules are OS agnostic, working with any host operating system, or even without a host OS.

IDS have designed a complementary UI software tool to enable rapid and simple implementation of a GUI which is then stored within the on-board flash memory.Once you have installed the drivers for the USB UART to UART Display & the UART Windows software on your PC you are ready to start connecting your display (RS232/USB) and uploading your images.

Manipulate specific parts of the screen by overlaying text, or images, even create scrolling effects by shifting regions of the display. Very quickly you will get an idea of how your designs will look on the display, and how you might trigger them with simple command line instructions.

The integrated fonts and basic character/draw functions, such as text, pixel, line, right angle and circle, permit an attractive GUI to be up and running within a short amount of time. Images or graphics can be stored in 65,000 colours in the internal Display Flash, to be displayed when needed.Data is exchanged between the UART system, (UART, RS232, or USB) and your microcontroller - enabling real time interaction, and animations in high resolution,on a TFT from a few simple lines of code.

The large amounts of data that usually need to be transferred from the host system each time a TFT display updates are held on-board, dramatically reducing the strain on the CPU workload.

Featuring simple, low-overhead mechanical and technical integration, these displays are suited for the first time user or experienced display integrators.

IDS have produced a range of UART kits making it even easier to be up and running within minutes, containing a display, power supply, cables, software and example code and images.

In electronics world today, Arduino is an open-source hardware and software company, project and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Arduino board designs use a variety of microprocessors and controllers. The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (‘shields’) or breadboards (for prototyping) and other circuits.

The boards feature serial communications interfaces, including Universal Serial Bus (USB) on some models, which are also used for loading programs. The microcontrollers can be programmed using the C and C++ programming languages, using a standard API which is also known as the “Arduino language”. In addition to using traditional compiler toolchains, the Arduino project provides an integrated development environment (IDE) and a command line tool developed in Go. It aims to provide a low-cost and easy way for hobbyist and professionals to create devices that interact with their environment using sensors and actuators. Common examples of such devices intended for beginner hobbyists include simple robots, thermostats and motion detectors.

In order to follow the market tread, Orient Display engineers have developed several Arduino TFT LCD displays and Arduino OLED displays which are favored by hobbyists and professionals.

Although Orient Display provides many standard small size OLED, TN and IPS Arduino TFT displays, custom made solutions are provided with larger size displays or even with capacitive touch panel.

ST cooperates with Riverdi because we believe that such partnership brings value to our joint customers. On top of this, we also discovered that we shared some business visions about how to make it easier and faster to go from the initial stages of designing a product embedding a graphical user interface to a production ready product. The conclusion was that combining the STM32 High performance microcontrollers, with the free STM32 graphics toolchain and Riverdi displays + PCB and then merge all of this into a board support package ready to run TouchGFX, would be a compelling offering.

Designing and developing a product with an embedded user interface (GUI), can be complex, as it involves many building block and disciplines, which all requires expert knowledge. Riverdi offer is covering a lot of them, allowing the customer to focus on the most important part of the development, the GUI Application itself. And remember that this is the face of your product. Choosing such solution, the customer does not need to worry about sourcing components like the display, microcontrollers, memory, etc. or even writing low-level drivers, development the board support package or porting TouchGFX. Its all ready done. What makes cooperation with Riverdi unique is that Riverdi has been able to drive a 1280*800 display resolution in high colors, with a STM32H7 microcontroller and a TouchGFX application showing a smart home UI. This shows that Riverdi is well aware of how to exploit all the capabilities of the STM32 Graphics offering combining hardware and software in a unique solution. From the first business meetings, it was clear that we shared visions of the market for embedded GUIs. And Riverdi proved that they can go from an idea and concept to actual working hardware, very fast.

This note will discuss the considerations made when choosing a microcontroller that will work for your display. A few requirements need to be met depending on the display’s features, interface, and size. These can also be determined by the embedded IC in the display. An overview of the considerations when choosing a microcontroller can be seen below. It should be noted that these items are separated for definition but may serve the same purpose and be interconnected in the ecosystem of the controller.

Application and display specific peripheral requirements. I2C, SPI, UART, Parallel, MIPI, LVDS, HDMI etc. Determines pin connections and required architecture of the device.

Flash and RAM memory requirements. Minimum frame buffer memory is dependent on the size andresolution of the display. Location of memory (external or internal) can restrict interface speed and must becompatible with the chosen interface.

Communication speed requirements defined by the interface and intended application. Refresh rateis determined on the size of the display and location of memory. This will indicate which processors arecompatible.

A displays embedded IC can offer resources such as internal RAM, clock generators and power control.This can save resources otherwise needed to be provided externally. Check the datasheet of the display’s ICcontroller for device function specifics.

Availability of resources for programming and debugging the microcontroller. Online resources andexampleprograms to leverage from can a lot of save time. Compatibility with a familiarprogramming environment isadditionally beneficial.

The interface selection is dependent on the intended application of the display. Each display has a different interface or different choices for a connection interface. For smaller displays a 3/4-wire serial interface would be sufficient. For larger display’s with high resolution a faster interface should be chosen. A parallel RGB interface is capable of high-speed data transmission however requires many pin connections. If the intended application for the display is video a MIPI, LVDS or HDMI connection would be a good choice.

The available memory of a microcontroller often becomes a highlighted issue when determining which microcontroller to select. The microcontroller needs a minimum amount of RAM to hold the frame buffer of the display. Even small displays require more RAM than a typical microcontroller possess. To verify that your microcontroller will have enough memory, it is important to calculate the frame buffer.

The minimum RAM required for the frame buffer in this example would then be 768kB. It is important to note that external RAM can be provided for the frame buffer if the microcontroller does not provide it internally. Clocking speed should be verified if using external RAM as the microcontroller cannot access external RAM as quickly. The clock frequency constrained by external RAM sometimes does not meet the minimum requirements of some very high-speed interfaces (ex. DSI-MIPI). Additionally, the display can contain some form of RAM depending on the IC controller inside the display. This can be verified on the specification sheet of the IC.

The speed of the microcontroller is heavily dependent on the interface used in the application. The minimum and maximum of the clock frequency is specified in the datasheet of the display and in the specification sheet of the display’s controller IC. The frame rate is typically around 50-60Hz, which is the median oscillation frequency to refresh the display to maintain an image. The display will often provide an internal high frequency clock that can be initialized to certain frequencies.

It is important to verify in the controller data sheet which resources are provided by the internal IC of the display. Some key information to look for would be: Does the display have sufficient RAM or does this need to be provided? Does the display have an internal oscillator for clock generation for the interface chosen? An additional graphics controller can be used to interface the display with the microcontroller to meet these requirements. Features like these can be utilized to avoid additional cost, space, and memory of your application.

After a brief consideration of intended application and interface of the display you can get some idea of which microcontroller processor and architecture you will need. There are a few different microcontroller processors to choose from. The main choices are ARM, AVR, PIC, and 8051. The difference between them is the bit size of the processor, 8-bit, 16-bit, 32-bit or 64-bit data . The data bit width is the amount of data that can be sent at a time. This determines the speed of data transfer and thus compatible applications and interfaces.

The AVR has an 8-bit processor and is a RISC type microcontroller. This type of processor is compatible with low speed interfaces (SPI, I2C) and smaller displays. A common AVR microcontroller board is the Arduino which has the embedded 8-bit ATMEL RISC processors. These processors are widely popular which provide the benefit of numerous online resources and availability. The Arduino processors (ATmega/SAM3X) are typically available in most microcontroller programming environments. Additionally, Arduino offers 32-bit AVR development boards which function closely to the ARM processors.

The AVR microcontrollers are constrained by the low frequency, internal memory availability and power costs. AVR’s cannot use external program memory but some may allow expansion of external SRAM. These microcontrollers alone would be incompatible for high frequency applications such as video, large displays, or capacitive touch panels.

The ARM microprocessors have a RISC architecture. They offer 32-bit or 64-bit processors and are great options for high speed interfaces (Parallel, LVDS, MIPI, HDMI) and high-resolution displays. Common ARM processors can be found from STMicroelectronics and Raspberry Pi. The most common version of the ARM processors is the “Microcontroller” Arm-M group which include the Cortex-M0 and Cortex-M4 series.

The ARM processors are compatible with most displays and connection interfaces. These microcontrollers have become increasingly popular, so the cost has become comparable between the ARM and the AVR types. These processors provide the speed, but it is recommended to verify the available RAM as these boards vary widely on included features.

The Intel MCS-51, more commonly known as the 8051 microcontrollers have a CISC architecture and an 8-bit processor. These processors differ in architecture from the previous and are programmed using a combination of C and assembly languages. The program memory is read only and does not have an on-board ISP. A special programming device is needed to rewrite the EEPROM or flash memory. These processors are typically small, low cost and low powered. This can make them favorable for battery powered devices. These processors are commonly used to initialize TFT displays and are combined with a graphics controller to provide the required resources such as RAM and clock frequency.

Development environments and online resources become considerably valuable when creating an application for your display. A brand new or uncommon microcontroller will have very few resources for reference. Even knowledgeable engineers can find frustrations with the manufacturers programming environments. There are many microcontroller choices that will support your display with similar and overlapping features. Choosing a microcontroller with an available FAQ, application notes or is accessible on a familiar programming platform can save a lot of time.

Raspberry Pi is a Palm Size computer that comes in very handy when prototyping stuff that requires high computational power. It is being extensively used for IOT hardware development and robotics application and much more memory hunger applications. In most of the projects involving the Pi it would be extremely useful if the Pi had a display through which we can monitor the vitals of our project.

The pi itself has a HDMI output which can be directly connected to a Monitor, but in projects where space is a constrain we need smaller displays. So in this tutorial we will learn how we can interface the popular 3.5 inch Touch Screen TFT LCD screen from waveshare with Raspberry pi. At the end of this tutorial you will have a fully functional LCD display with touch screen on top of your Pi ready to be used for your future projects.

It is assumed that your Raspberry Pi is already flashed with an operating system and is able to connect to the internet. If not, follow the Getting started with Raspberry Pi tutorial before proceeding.

Connecting your 3.5” TFT LCD screen with Raspberry pi is a cake walk. The LCD has a strip of female header pins which will fit snug into the male header pins. You just have to align the pins and press the LCD on top of the Pi to make the connection. Once fixed properly you Pi and LCD will look something like this below. Note that I have used a casing for my Pi so ignore the white box.

Step 2: Navigate to Boot Options -> Desktop/CLI and select option B4 Desktop Autologin Desktop GUI, automatically logged in as ‘pi’ user as highlighted in below image. This will make the PI to login automatically from next boot without the user entering the password.

Step 3: Now again navigate to interfacing options and enable SPI as show in the image below. We have to enable the SPI interface because as we discussed the LCD and PI communicates through SPI protocol

Step 7: Now use the below command to restart your Pi. This will automatically end the terminal window. When the PI restarts you should notice the LCD display also showing the boot information and finally the desktop will appear as shown below.

You can also watch the video below to check how the LCD is connected and how it responds to touch. I am pretty much satisfied with its default accuracy so I am not going to do any calibration. But if you are interested you can view the official wiki page from waveshare where they discuss how to calibrate and enable camera view on the LCD screen.

Hope you understood the tutorial and were successful in interfacing your LCD with PI and got it working. If otherwise state your problem in the comment section below or use the forums for more technical quires.
