round tft lcd module code supplier

A wide variety of round lcd module options are available to you, such as original manufacturer, odm and agency.You can also choose from tft, ips and fstn/cstn round lcd module,

LCD, or Liquid Crystal Displays, are great choices for many applications. They aren’t that power-hungry, they are available in monochrome or full-color models, and they are available in all shapes and sizes.

Waveshare actually has several round LCD modules, I chose the 1.28-inch model as it was readily available on Amazon. You could probably perform the same experiments using a different module, although you may require a different driver.

Once you have everything hooked up, you can start coding for the display. There are a few ways to do this, one of them is to grab the sample code thatWaveshare provides on their Wiki.

The Waveshare Wiki does provide some information about the display and a bit of sample code for a few common controllers. It’s a reasonable support page, unfortunately, it is the only support that Waveshare provides(I would have liked to see more examples and a tutorial, but I guess I’m spoiled by Adafruit and Sparkfun LOL).

Open the Arduino folder. Inside you’ll find quite a few folders, one for each display size that Waveshare supports. As I’m using the 1.28-inch model, I selected theLCD_1inch28folder.

Once you do that, you can open your Arduino IDE and then navigate to that folder. Inside the folder, there is a sketch file namedLCD_1inch28.inowhich you will want to open.

When you open the sketch, you’ll be greeted by an error message in your Arduino IDE. The error is that two of the files included in the sketch contain unrecognized characters. The IDE offers the suggestion of fixing these with the “Fix Encoder & Reload” function (in the Tools menu), but that won’t work.

The code is pretty basic, I’m not repeating all of it here, as it consists of several files.  But we can gather quite a bit of knowledge from the main file, as shown here.

You can see from the code that after loading some libraries we initialize the display, set its backlight level (you can use PWM on the BL pin to set the level), and paint a new image. We then proceed to draw lines and strings onto the display.

Unfortunately, Waveshare doesn’t offer documentation for this, but you can gather quite a bit of information by reading theLCD_Driver.cppfile, where the functions are somewhat documented.

After uploading the code, you will see the display show a fake “clock”. It’s a static display, but it does illustrate how you can use this with the Waveshare code.

This library is an extension of the Adafruit GFX library, which itself is one of the most popular display libraries around. Because of this, there isextensive documentation for this libraryavailable from Adafruit.  This makes the library an excellent choice for those who want to write their own applications.

Here is the hookup for the ESP32 and the GC9A01 display.  As with most ESP32 hookup diagrams, it is important to use the correct GPIO numbers instead of physical pins. The diagram shows the WROVER, so if you are using a different module you’ll need to consult its documentation to ensure that you hook it up properly.

The TFT_eSPI library is ideal for this, and several other, displays. You can install it through your Arduino IDE Library Manager, just search for “TFT_eSPI”.

There is a lot of demo code included with the library. Some of it is intended for other display sizes, but there are a few that you can use with your circular display.

A great demo code sample is theAnimated_dialsketch, which is found inside theSpritesmenu item.  This demonstration code will produce a “dial” indicator on the display, along with some simulated “data” (really just a random number generator).

In order to run this sketch, you’ll need to install another library. Install theTjpeg_DecoderLibrary from Library Manager. Once you do, the sketch will compile, and you can upload it to your ESP32.

The Animated Eyes sketch can be found within the sample files for the TFT_eSPI library, under the “generic” folder.  Assuming that you have wired up the second GC9A01 display, you’ll want to use theAnimated_Eyes_2sketch.

The GC9A01 LCD module is a 1.28-inch round display that is useful for instrumentation and other similar projects. Today we will learn how to use this display with an Arduino Uno and an ESP32.

WF0128BTYAA4DNN0 is a round IPS TFT-LCD screen with a 1.28-inch diameter display with resolution 240x240 pixels. This round TFT display comprises an IPS TFT-LCD panel built with a GC9A01 driver IC that can communicate via SPI interface.

WF0128BTYAA4DNN0 is adopted IPS panel, which has the advantage of higher contrast, true black background when the display or pixel is off and wider viewing angle of Left:80 / Right:80 / Up:80 / Down:80 degree (typical), contrast ratio 1,000:1 (typical value), brightness 400 nits (typical value), anti-glare surface panel. If customers require Capacitive Touch Panel, please choose model No. WF0128BTYAA4DNF10.

The power supply voltage of LCM is from 2.7V to 3.3V, the typical value of 2.8V. It can be operating at temperatures from -20℃ to+ 70℃ and storage temperatures from -30℃ to +80℃. The display modules are suited for compact devices like smart gauges, wearable devices, and meter applications. They are also ideal for home automation products, white products, and video systems.

This 4D Systems Display Module Pack for the Arduino (and variants) is made up of a uLCD-220RD 1.38" Round TFT LCD Display Module and an 4D Arduino Adaptor Shield to easily connect an Arduino to the 4D Systems Display.

This Display Module Pack enables an Arduino user to quickly connect the 4D Arduino Adaptor Shield to their Arduino, connect the 5 way cable between the Adaptor and the Display Module, and be connected in seconds to start programming their new 4D Systems Display.

The uLCD-220RD can be configured in a number of ways using the 4D Systems Workshop4 IDE. There are 4 programming Environments to choose from, to enable the widest range of options possible and to suit a wide range of Users and projects alike.

For a detailed listing of the capabilities of the display module in this Arduino Pack, please refer to the datasheet for the display itself, available from the Product Page of the uLCD-220RD.

Raystar is a global leading LCD panel supplier and specialized in producing TFT LCD Panel, including Color TFT, Monochrome TFT Display and bar type TFT Display. Raystar Color TFT displays are available in various resolutions and offers a wide product range of small to medium-sized TFT-LCD modules from 0.96” to 12.3". The interface options are in MCU / RGB / SPI / UART / 8080 / LVDS. TFT Panel with control board or TFT LCD Panel with micro controller are also available.

This is a 2.2” TFT LCD Display Module with an input voltage of 3.3V~5.5V, which is used to display colorful patterns and characters. The fastest screen refresh speed is about 256ms. The module is able to display multiple patterns in a cycle and realize dynamic display effect. At present, there are 19 common defined colors in the library, and users can also customize16-bit color codes. If we take the central point of the display as the origin of coordinates, the maximum absolute value of the positive and negative axis will be 64.
