adafruit tft lcd display model 1480 brands

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 or compatible) can display full 18-bit color (262,144 shades!). And the LCD will always come with the same driver chip so there"s no worries that your code will not work from one to the other.

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!

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!

Playing piano often takes years to learn. These three Cornell undergraduates embedded LEDs into the keys of a play-along keyboard and used a PIC32 as the interface to guide users note by note through songs. Sheet music for the songs was shown on a TFT display.

The piano requires years of practice to master, but with our play-along keyboard, the bar to entry is much lower! We used a PIC32 microcontroller, some LEDs, and an off-the-shelf keyboard to make a tool that helps people learn to play classic and recognizable tunes on the piano. The finished keyboard is shown in Figure 1. We embedded LEDs into the keyboard and designed software to guide the user, note by note, through each song. The LEDs on the correct keys illuminate, while a thin-film-transistor (TFT) screen displays the sheet music. When the user presses the correct notes, the set of illuminated LEDs and the sheet music advance. Experienced users can simply read the displayed sheet music, whereas those who have never played piano before can start playing and working through songs of their choice. This interface makes this play-along keyboard a good learning tool for users at all levels of experience.

The core of our project consists of an Alesis Melody 32 commercial 32-key keyboard and a PIC32 development board Figure 2[1] containing several peripheral devices. The heart of the development board is the PIC32MX250F128B microcontroller. The MCU is connected to an MCP23S17 port expander [2] for extra input/output pins, and an Adafruit Model 1480 TFT LCD display. The development board also contains headers connected to every pin of the PIC32, a power connector, and a reset switch. The TFT display and port expander communicate with the microcontroller over a serial peripheral interface (SPI).

Using a standard format such as MIDI initially seemed appealing for storing and representing song files; however, our desire to display the songs as sheet music made most standard formats difficult to use. We decided for this reason to use our own format and wrote a Python script to translate between a format that is easy to write and a data structure that is easy to work with in code.

On reset, the TFT display presents the main menu with a list of song choices and the Freeplay mode option. The user navigates within the menu and makes a selection, using the three leftmost keys on the keyboard. If the user selects Freeplay mode, no music is displayed; instead, when a key is pressed, the associated LED illuminates. We added this mode for debugging purposes but retained it as a feature. If the user selects a song in the main menu, the TFT display shows the first two measures of the song (with the current note and chord highlighted in red), and the LEDs for the keys required to play those notes illuminate. When the user presses all the lit keys at the same time, the next set of keys lights up, and the next note on the sheet music is highlighted. This process of pressing the highlighted keys continues until the song is finished, at which point, after a brief delay, the keyboard returns to the main menu. The user can also press the reset switch at any point to exit the current song and return to the main menu.

We modeled and 3D printed an enclosure and mount for the TFT display. We originally planned to mount the display in the center of the keyboard but settled on the left side closer to the PIC32 board, due to the wire length. We cut a hole in the keyboard’s case using a Dremel tool to allow the display cable to pass through and then attached the display enclosure with hot glue and electrical tape.

For the reset switch, we soldered two wires to the existing reset switch on the development board and passed them through a hole in the keyboard case. Then we soldered those wires to an external switch, which we taped to the back of the case. Since the keyboard case matched the electrical tape we were using, we were able to quickly attach the switch and display enclosure without sacrificing too much in terms of aesthetics.

Why do we need a port expander? The PIC32 has only 19 GPIO pins, five of which are used by the TFT display. Since we need six GPIO pins to drive the LED circuit and another 13 pins for detecting key presses, (discussed later), we need the port expander for the additional GPIO pins. The port expander, itself, uses an SPI interface that requires four GPIO pins, and two for interrupts, but effectively gives us another 16 in return—enough inputs/outputs for this project.

The code for our project is available for download [4]. Our software contained a few important data structures and modules to interface with the hardware and the display. We controlled the LEDs through our software’s led.h module. This module stored the state of the LEDs as a 32-bit integer. It provided two functions to our main method—one to initialize the LEDs and one to set them. This allowed us to simply pass a 32-bit integer representing the status of the 32 LEDs into the leds_set function and let the led module handle the rest.

A more complex player module manages to play a song and display the sheet music. This player module exposes two functions: song_start, which starts playing a song, and player_update, to update the currently playing song. The player_update function must be called often if the player is expected to be responsive; it manages writing to the display, polling the keys, and updating the LEDs a single time. The fact that our player module depends on an outside source consistently calling player_update to function properly is not a great modular design choice, but it worked for our needs. Were we to continue work on or extend this project, we could refactor this module to remove this dependency.

Originally, we chose to leave the TFT blank during our Freeplay mode, but to ensure that the TFT was working during this mode, we decided to display a placeholder background trapezoid. We are very proud of how easily our modular design allowed elegant implementation of our Freeplay mode. We simply call the leds_set function with the keys_poll function as the argument. In one line of code, the LEDs are set to reflect exactly what keys are pressed, in real-time. We had originally implemented this to test that both the keys and the LEDs were mapped correctly, but we also thought that it could be a fun feature for the user.

We gave careful consideration to how we represented the music in software. Some musical background is needed to understand why we made these choices. We will go over some of the basics here but have also added articles about musical notation in the resources section. We wanted to do two things for each song: display the notes on the piano, and display the sheet music (Figure 8) on the TFT.

Given this background, we decided we needed a format in which, at a specific time, we could simultaneously represent the notes in both the chord and melody. Melody notes were represented with their letters and octave numbers, and the chord was represented as a group of notes. We did not have space in the sheet music to display the individual notes in the chords, so we decided to display the sheet music for the melody only, and to display the chord name above the music (Figure 9). The individual keys for the chord are still displayed on the keyboard. Representing chords in this way is common in sheet music.

We “wrote” our songs to a text file delimited by line breaks. The first three lines were the song title, the beats per minute (currently unused), and the octave number. The octave number indicated to shift the sheet music representation by one or more octaves. This allowed a wider range of notes to fit in the limited height of the TFT display.

All the information that we needed to display the proper keys and the sheet music was thus provided. With a simple sheet music graphic library that we wrote, we could display flats, sharps, and all types of notes by using the information we had from each quanta. However, for musicians reading this, the system had limitations. We defaulted to writing all the music in the treble clef, in 4/4 time, and with no key signature. We also did not have support for rests, since many basic beginner songs do not need them. Although most of these things could be readily handled with the format we have set up, we felt it was still important to acknowledge the limitations.
