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.
Before I start, I want to mention that I did not write this code. This is a PORT from the mcufriend’s arduino code, which can be found HERE. I merely made some changes, so that it can be used with the CubeMx with a little modifications.
Now comes the part for setting up the Pins for the display. As, we are using the parallel connection, there are 8 DATA Pins and 5 CONTROL Pins. It would be really easy, if you connect all the data pins to thesame PORTand in the same order.
According to the Setup, the LCD_D2 is connected to the PA15. So if I want to write the DATA to the LCD_D2 pin, first I will select the 2nd bit of the data (d & (1<<2)), and than shift this by 13 using <<13. This will be like adding 2 with 13 to make a total of 15, and that’s where the LCD_D2 is connected to.
I have a small 3.5 in TFT LCD display from a Chinese manufacturer. It doesn"t have an integrated LCD controller. The documentation claims it is a "16 bit RGB/parallel interface" and it uses a Renesas R61581B0 driver chip.
These types of displays are very common and cheap. They sell for less than $15 a pop on Alibaba.com, but I don"t really have a high esteem for these manufacturers since they do not provide any good / consistent documentation, and their English is riddled with mistakes! But I did get the display, and the product looks and feels like it will do the job!
My question now is, how do I get started ? I have looked on the internet and cannot find a good starting point. I have a 32MHz microcontroller in mind, but I am stumped on how to interface it with the LCD.
Most display projects online that I"ve seen assume that the LCD module comes with an integrated controller , so the MCU"s job becomes pretty simple.. Provide image updates when necessary, and the controller will do the job of refreshing the LCD module at the required 60hz (or so)
This LCD module that I have has raw data lanes that I need to drive myself at 60hz. Are there any good documents on how to interface an MCU directly with such an LCD module?
I"ll be happy with any info that points me in the right direction, whether it be an answer on stackexchange or a reference to any good documentation online.
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.
This guide is about DWIN HMI Touch Screen TFT LCD Display. HMI Means Human-Machine Interface. DWIN is specialized in making HMI Touch screen displays that are compatible with all microcontrollers like Arduino, STM32, PIC, and 8051 families of Microcontrollers.
This is a Getting Started tutorial with 7-inch DWIN HMI TFT LCD Display. We will see the architecture, features, board design, components, and specifications. We will also learn about the TTL & RS232 interfaces. Using the DGUS software you can create UI and with SD Card you can load the firmware on display memory.
You can change the TTL Interface mode or RS232 mode from here. Just solder these two terminals as shown here to enable TTL Interface. By default, the module is in RS232 Interface.
One of the method to load the firmware to the T5L DWIN LCD Display is by using the SD Card. An SD Card of up to 16GB can be used to download the firmware files. We can easily insert the Micro SD card into the SD Card slot on the backside.
After copying the file, remove the SD Card from your computer and insert it into the SD Card slot of DWIN LCD Display. Then power the display using the USB Cable. The firmware downloading process will start automatically.
The next part of this tutorial includes creating UI and interfacing DWIN LCD Display with Arduino. For that you can follow the DWIN LCD Arduino Interfacing Guide.
The ST7789 TFT is a color display that uses SPI protocol. This display is an IPS display, it comes in different sizes (1.3″, 1.54″ …) but all of them should have the same resolution of 240×240 pixel.
The ST7789 display module shown in project circuit diagram has 7 pins: (from right to left): GND (ground), VCC, SCL (serial clock), SDA (serial data), RES (reset), DC (or D/C: data/command) and BLK (back light).
The ST7789 TFT display works with 3.3V only (power supply and control lines). The display module is supplied with 3.3V that comes from the AMS1117 3V3 voltage regulator, this regulator steps down the 5V into 3.3V (supplies the display controller with regulated 3V3).
To connect the PIC18F46K22 with the display module, I used voltage divider for each line. This means there are 4 voltage dividers. Each voltage divider consists of 2.2k and 3.3k resistors, this drops the 5V into 3V which is sufficient.
If the display module has a CS pin (Chip Select) then it should be connected to the PIC18F46K22 microcontroller through another voltage divider (for example connecting it to pin RD2).
In this project SPI1 module is used with SCK1 on pin RC3 (#18) and SDO1 (MOSI) on pin RC5 (#24). SCK1 and SDO1 pins of the PIC18F46K22 MCU are respectively connected to SCL and SDA pins of the ST7789 display module.
The default connection setting of the mikroC ST7789 TFT library is hardware SPI1 module (SPI1 module must be initialized before initiating the display). Instead of hardware SPI1 module, software SPI or hardware SPI2 module can be used.
If TFT data pin (TFT_DIN) and clock pin (TFT_SCK) are defined in the main code (before #include “ST7789.c”) then the library will automatically use software SPI.
If the display module has a CS pin uncomment its related lines (#define TFT_CS and #define TFT_CS_DIR) and connect it to RD2 pin of the microcontroller through voltage divider.
