3.2 lcd touch screen in stock

I needed a reasonable size LCD display for my Rpi 3B+ so that I could display the range data coming from my Slamtec RPLidar A1M8 in real time. I was going to use the recommended Adafruit LCD Display for the project, but decided on the Waveshare LCD Display because it had higher resolution, I could get it sooner, and I saved $14.

The LCD Display Module attached easily to my Rpi 3B+ GPIO bus and then I proceeded to follow the Waveshare Wiki guide for installing the software. After downloading the software onto my Rpi 3B+, using SSH, I don"t recommend installing it from the SSH CLI as the installation process will disconnect the SSH window from the Rpi. Therefore it is best to attach a monitor, keyboard, and mouse to your Rpi to complete the installation per the Waveshare Wiki guide using the Buster Desktop terminal.

After a reboot, the Waveshare LCD Display Module software functioned as expected. The Display was crisp and clean without any dot bleed over and the touch screen functioned as advertised.

If you are an experienced user of the Rpi, I would highly recommend this LCD Display Module if you need a LCD Display Module to go with an Rpi project. That being said, Rpi beginners may have some difficulty with the software installation.

※ 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-TFT032-2 is 240x320 dots 3.2 " color tft lcd module display with ILI9320 controller and optional 4-wire resistive touch panel,superior display quality,super wide viewing angle and 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 and hand-held equipment which requires display in high quality and colorful image.It supports 8080 16-bit parallel interface. .FPC is soldering type,there is no need for zif connector.Lanscape mode is also available.

Fully assembled 3.2inch display with 320x240 pixels TFT LCD and a resistive touch overlay. Just plug it on top of ODROID-C1. 2x13 tall female header is already soldered on the PCB.

This 3.2″ TFT LCD is a full color display with a resolution of 240 x 320 pixels or 320 x 240 pixels depending on how it is oriented.  It uses the ILI9341 controller with SPI interface.  It also includes a resistive touchscreen with built-in XPT2046 controller.

These full color displays are large enough for many applications even when using touch.  The supplied stylus is helpful when using smaller touch targets.

These are interesting modules to work with since they have full color and graphical capability with good library support and the touch capability adds a new dimension of usefulness.

I’m also using the Teensy 4.1 because it is currently the fastest Arduino compatible board (600MHz 32-bit vs Uno 16MHz 16-bit) and this example application of calculating Mandelbrot fractals and updating the LCD can take a long time on an Uno (77-105 seconds) and only takes about 1.25 seconds on the Teensy 4.1.  If using a 3.3V Arduino like a Due, hookup will basically be the same.

The program below is a modified version of the Mandelbrot example program that gets installed with the Adafruit_ILI9341 library.  It was pruned down in size and basic touch added.  The program just calculates the Mandelbrot set and draws it to the screen pixel-by-pixel as it is calculated.  The math is fairly intense for each pixel, so it is a good judge of the power of the MCU.  The display update speed is thus limited by the MCU that is doing the calculations and is not limited by the display itself.

After drawing the first screen, it waits until the touchscreen is touched and then it zooms in slightly and redraws the screen.  It also reports the touch location information out to the Serial Monitor window and also reports how long it took to calculate that screen.  If you want to evolve the program as an exercise, it would be interesting to use the touch coordinates to center the new zoom.
