We wanted to develop a highly accessible and portable augmented reality (AR) system that mimics the natural processes of bats, to localize object distances and to detect disturbances in 3D space. The SER is activated by switching on a power button, which is located on the side wall. By default, the system is in distance measurement mode, and will immediately begin displaying distances on the LCD screen. The mode can be changed by pressing the push button on the side of the SER [1].

The SER is implemented using a Microchip Technology PIC32 MCU, which sends out ultrasonic pulses to an analog amplifier and then to a central speaker module. The PIC32 monitors the ultrasound microphones immediately after emitting pulses, to detect echoes, compute object distances and identify object perturbations. The MCU converts the echo data into distance/perturbation data, which are displayed on the LCD screen.

When engineering the SER, we focused on creating a user interface that would allow for the best possible AR experience, while maximizing the effective range of the system. This was achieved by creating an intuitive visual display for the user, and by creating a physical housing for the circuitry that optimizes ease of use and effectiveness.

To program the AR display, we used a graphics library [5], text and rectangles on the TFT display [6]. For distance-measurement mode, the LCD displays a circle with a radius inversely proportional to the distance of the object. This was implemented in our code by setting the radius size of the circle to be drawn to be a negative linear function of the object distance. To show the object distance on the display, we simply print out the variable corresponding to the object distance to the desired location on the LCD screen. For perturbation mode, the LCD displays a blue circle if it detects a perturbation, and a red circle otherwise, with text indicating whether there is a perturbation.

The physical design of the SER includes secure housing for the electrical components, acoustic isolation of the speakers and microphones, and maximal concentration of the central sound lobe. Acrylic material was laser cut and used for walls (Figure 3). The MCU and circuitry was housed inside the acrylic enclosure. We used a 3D-printed mount to securely hold the TFT against the back wall. Velcro was used to affix the circuit and MCU parts to the walls, and to allow seamless opening and closing of the side walls. The speaker and microphone module were attached to the wall opposite the TFT. We used polyurethane adhesive and 3D-printed support struts to connect the walls and secure the Velcro strips.

To determine if a perturbation is present, the system checks if this number exceeds a threshold. If so, then a perturbation is registered, and the AR display outputs this information. Otherwise, the AR display indicates that there is no perturbation. The threshold is defined in software as a macro that can be changed by the user, depending on the desired sensitivity to surface-normal perturbations.

To conduct this test, we set the SER’s perturbation threshold to a particular value. Then we put the SER in perturbation mode, while a stationary plastic board located 0.60m away was held. We videotaped the AR display output for 30 seconds, and then we rotated the plastic board at a constant rate for another 30 seconds (while the display was being videotaped). We calculated the false-positive rate as the fraction of time when the board was still that the display indicated a perturbation.

Authors’ Notes: We would like to acknowledge the work of Adam Dunkels for developing the Protothreads library. We also used the TFT graphics library, which was developed by Adafruit and modified by Syed Tahmid Mahbub. This project would not have been possible without the work of Rajiv Kommareddy, who helped implement the project but did not take part in the writing of this article. Finally, we would like to extend our gratitude to Prof. Bruce Land [3] of Cornell University for helping us with the project.

This lovely little display breakout is the best way to add a small, colorful and bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available!

The 2.2" display has 320x240 color pixels. Unlike the low cost "Nokia 6110" and similar LCD displays, which are CSTN type and thus have poor color and slow refresh, this display is a true TFT! The TFT driver (ILI9340) can display full 18-bit color (262,144 shades!). And the LCD will always come with the same driver chip so theres no worries that your code will not work from one to the other.

The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. We also had a little space so we placed a microSD card holder so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card. The microSD card is not included.

Of course, we wouldnt just leave you with a datasheet and a "good luck!" - weve written a full open source graphics library that can draw pixels, lines, rectangles, circles, text and bitmaps as well as example code. The code is written for Arduino but can be easily ported to your favorite microcontroller! Wiring is easy, we strongly encourage using the hardware SPI pins of your Arduino as software SPI is noticeably slower when dealing with this size display. Check the example sketches for wiring help until we get a detailed wiring tutorial written!

I recently bought a Raspberry Pi and had bought a (2.2 Inch Serial TFT SPI LCD Screen Module HD 240 x 320 5110 Compatible) display off the web a while ago. I wanted to connect the two together, so not being able to find a specific sample on the web, I wrote my own.

Oldieman has provided details on how to get this working on the  Adafruit PiTFT Mini Kit 320x240 2.8" TFT+Capacitive Touch screen ADA1983. See his comments below...

Adafruit also had a little extra space on the back so there is a microSD card holder for easily loading full-color bitmaps from a FAT16/FAT32 formatted microSD card.

The Adafruit 2.2″ TFT LCD with MicroSD Card also features an EYESPI connector for a simpler connection to the LCD. EYESPI is a single 18-pin FPC used as a quick way to connect displays.

The Adafruit TFT FeatherWing has a touch screen display on the front and a socket for any Feather on the back, including the Particle Argon, Boron, and Xenon. You can find technical information at Adafruit.

This display breakout also features a 18-pin "EYESPI" standard FPC connector with flip-top connector. You can use a 18-pin 0.5mm pitch FPC cable to connect to all the GPIO pins, for when you want to skip the soldering.

As of November 2022 - Adafruit have updated this TFT breakout with a EYESPI connector to make cabling easier with an 18-pin FPC. They also used Adafruit Pinguin to make a lovely silkscreen. The board is otherwise the same size, pinout, and functionality.
