tft display ili9481 4th dimensional innovations supplier

This TFT display is big (3.5″ diagonal) bright and colorful! 480×320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128×64 display, and double our 2.8″ TFT.

As a bonus, this display has aresistive touchscreensensor allowing you to control your application simply by touching any area of the screen. This display has a controller built into it with RAM buffering so that almost no work is done by the microcontroller.

ThisLCDmodule is suitable for a user who requires high resolution and brightness, brilliant and all angle viewable display quality, display quality is as good as standard mobile screens.

The display can be used in two modes: 8-bit or SPI. For 8-bit mode, you’ll need 8 digital data lines and 4 or 5 digital control lines to read and write to the display (12 lines total). SPI mode requires only 5 pins total (SPI data in, data out, clock, select, and d/c) but is slower than the 8-bit mode. In addition, It requires 4 pins for the touchscreen (2 digital, 2 analogs).

This is the larger version of the 2.4″ display designed specifically for the Arduino Mega. This 3.5″ display and is designed to fit directly into the standard headers of an Arduino Mega requiring no additional interface hardware.

I decided to integrate a Cortex M0 MCU with the 640×360 TFT LCD from the Sony U5 Vivaz mobile phone. If you haven’t already done so then you can read all about my prior efforts in reverse engineering that display in this article. The graphical user interface will be supported by an 8Mbit SPI flash device from Spansion.

TFTs always need two voltage inputs, one for the digital interface and one for the analog display driver. If you’re lucky they’re both the same and fit the same range as your MCU. We’re not so lucky with the R61523. The digital interface will take 3.3V but the analog voltage requires 2.8V. That’s no problem, we just drop in this small and cheap regulator.

There’s three words you don’t often see used together. Surely a 1-bit interface is never going to be fast enough for interactive graphics? Well, it is. By running the SPI interface at the fastest 24MHz rate offered by the MCU and utilising DMA to transfer big blocks at once we achieve bursts of 1.5 megapixels/sec. This is more than fast enough to update just the changing parts of the display in real-time.

Assuming the user hits go then the action starts. The PID algorithm will be repeatedly run to select a low-frequency PWM signal for the halogen lamp as the algorithm attempts to track the reflow profile. The actual temperature will be displayed in orange just below the desired temperature. A red-line will plot across the chart to show how the oven is performing.

Here it is switched on. The front panel buttons are illuminated and the control page is being displayed. It’s notoriously difficult to photograph an LCD display and this photograph does little to convey just how bright and colourful it is in reality. The controller box feels very light in the hand, maybe I should glue a brick inside to give it that ‘quality’ feel

Then open a web browser and type in http://192.168.1.1. to display the WiFi configuration page. (This configuration page may also popup automagically.)

After approx 20 seconds, the Clock should now start and display the correct time. The Clock should display time and play the "Pacman" startup audio clip.

Note: the time will not change time zones until the clock is rebooted. Turn power to the clock off for 12 seconds then on again. The correct time for your time zone should now be displayed.

By the way, besides its performance, the large colour display is a good reason to consider purchasing an MSO5000series scope rather than one of its smaller cousins.

for its size. We found the screen pleasant to look at. Although there are settings to adjust trace intensity and graticule brightness, the various other display elements do not

The technology used is called Fused Deposition Modelling (FDM) or Fused Filament Fabrication (FFF). Dimensional accuracy is typically around 0.5mm. Parts can be
