I2C interface 4.4 STMPE610 Write operations A write is first performed to load the register address into the Address Counter without sending a Stop condition. After the bus master receives an acknowledgement from the slave device, it may start to send a data byte to the register (referred by the Address Counter). The slave device again acknowledges and the bus master terminates the transfer with a Stop condition.

STMPE610 5 SPI interface SPI interface The SPI interface in STMPE610 uses a 4-wire communication connection (DATA IN, DATA OUT, CLK, CS). In the diagram, “Data in” is referred to as MOSI (master out slave in) and “DATA out” is referred to as MISO (master in slave out). 5.1 SPI protocol definition The SPI (serial peripheral interface) follows a byte sized transfer protocol. All transfers begin with an assertion of CS_n signal (falling edge).
PAGE 280
SPI interface 5.1.2 STMPE610 Register write The following steps need to be followed for register write through SPI. 5.1.3 1. Assert CS_n by driving a '0' on this pin. 2. Drive a '0' on the first SCL launch clock on MOSI to select a write operation. 3. The next 7 bits on MOSI denote the 7-bit register address (MSB first). 4. The next byte on the MOSI denotes data to be written. 5. The following transmissions on MOSI are considered byte-sized data.

STMPE610 Touchscreen controller Window tracking The -WDW_X and WDW_Y registers allow to pre-set a sub-window in the touchscreen such that any touch position that is outside the sub-window will be discarded. Figure 10. Window tracking Top right coordinates Active window Bottom left coordinates FIFO FIFO has a depth of 128 sectors. This is enough for 128 sets of touch data at maximum resolution (2 x 12 bits). FIFO can be programmed to generate an interrupt when it is filled to a pre-determined level.

STMPE610 10.2 Touchscreen controller Touch detect delay Touch Detect Delay is an additional method used to compensate for the time it takes for the panel voltage to be pulled high during a non-touch condition. For example, the way it works to detect a touch: X+ is pulled high and Y+ is driven low. After Touch Detect Delay is expired the level of X+ is read. If no touch, X+ is high. If there is a touch, X+ is low.

GPIO controller 12 STMPE610 GPIO controller A total of 6 GPIOs are available in the STMPE610 port expander device. Most of the GPIOs share physical pins with some alternate functions. The GPIO controller contains the registers that allow the host system to configure each of the pins into either a GPIO, or one of the alternate functions. Unused GPIOs should be configured as outputs to minimize power consumption. A group of registers are used to control the exact function of each of the 6 GPIOs.

Overview Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display.
PAGE 326
This shield uses a SPI display - its much easier to use with Mega & Leonardo than our v1 shield. We also include an SPI resistive touchscreen controller or a I2C capacitive touch screen controller so you only need one or two additional pins to add a high quality touchscreen controller. Even with all the extras, the price is lower thanks to our parts sourcing & engineering skillz! © Adafruit Industries https://learn.adafruit.
PAGE 327
The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you'll have it running in under 10 minutes! Works best with any classic Arduino (UNO/Duemilanove/Diecimila). Solder three jumpers and you can use it at full speed on a Leonardo or Mega as well. This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller.
PAGE 331
Pinouts There's two versions of the shield. One has a resistive touch screen, one has a capacitive one. The TFT display and pinouts is the same for both. The microSD card is the same too. The differences come in on the touch screen controller TFT Screen Pins Digital #13 or ICSP SCLK - This is the hardware SPI clock pin. By default its digital #13. By cutting a jumper and soldering another on the back, you can move this line from #13 to the ICSP clock pin.
PAGE 332
screen data Digital #10 - This is the TFT CS (chip select pin). It's used by the Arduino to tell the TFT that it wants to send/receive data from the TFT only Digital #9 - This is the TFT DC (data/command select) pin. It's used by the Arduino to tell the TFT whether it wants to send data or commands Resistive Touch Controller Pins Digital #13 or ICSP SCLK - This is the hardware SPI clock pin. By default its digital #13.
PAGE 333
Digital #4 - This is the uSD CS (chip select pin). It's used by the Arduino to tell the uSD that it wants to send/receive data from the uSD only Using with an Uno Because the TFT is about the same size as an Arduino, we pre-assemble the shield in the factory. To use, simply place it onto your Arduino Uno/Duemilanove/compatible. No wiring, no soldering! Bam! Using with a Mega/Leonardo With just a little effort you can make this shield plug-n-play with the Mega/Leonardo.
PAGE 334
You can then cut the small line in between the #11, #12, #13 pads. This will free up digital #11, 12, and 13 for you to use on the Leo or Mega. That's it! No software or firmware hacking other than that is required. © Adafruit Industries https://learn.adafruit.
PAGE 335
With this mod, the shield uses the ICSP header for data so make sure your duino (or stack of shields) has a ICSP plugged into the socket as above! © Adafruit Industries https://learn.adafruit.
PAGE 336
Graphics Test We have a library with example code ready to go for use with these TFTs. The library is not incredibly fast and optimized but its a good start and can easily be ported to other micrcontrollers. However, we'll assume you're using an Arduino. Our github repository (http://adafru.it/d4d) contains all the code and examples you'll need for driving the TFT. You can download the latest ZIP by clicking the button below Download the Adafruit ILI9341 Library http://adafru.
PAGE 337
Restart the Arduino software. You should see a new example folder called Adafruit_ILI9341 and inside, an example called graphicstest. Upload that sketch to your Arduino! You should see a collection of graphical tests draw out on the TFT. © Adafruit Industries https://learn.adafruit.
PAGE 339
Adafruit GFX library The TFT LCD library is based off of the Adafruit GFX graphics core library. GFX has many ready to go functions that should help you start out with your project. Its not exhaustive and we'll try to update it if we find a really useful function. Right now it supports pixels, lines, rectangles, circles, round-rects, triangles and printing text as well as rotation. Check out the GFX tutorial for detailed information about what is supported and how to use it (http://adafru.
PAGE 340
Resistive Touchscreen Paint Demo This page is for the Resistive Touch Screen version of the Shield! The LCD has a 2.8" 4-wire resistive touch screen glued onto it. You can use this for detecting fingerpresses, stylus', etc. Normally, you'll need 4 pins to talk to the touch panel but we decided to go all snazzy and put a dedicated touch screen driver onto the shield.
PAGE 341
The touch screen is made of a thin glass sheet, and its very fragile - a small crack or break will make the entire touch screen unusable. Don't drop or roughly handle the TFT and be especially careful of the corners and edges. When pressing on the touchscreen, sometimes people can use the tip of their fingers, or a fingernail. If you don't find the touchscreen responds well to your fingers, you can use a rounded stylus which will certainly work.
PAGE 342
Check to make sure this returns a True value, which means the driver was found. If it wasn't, make sure you have the hardware SPI jumpers set up right: for Leonardo/Mega the ICSP jumpers get closed. Now you can call if (! ts.bufferEmpty()) to check if there's any data in the buffer. The touchscreen driver will store touchpoints at all times. When you're ready to get the data, just check if there's any data in the buffer. If there is, you can call TS_Point p = ts.
PAGE 343
to ask the driver "is the touchscreen being pressed RIGHT NOW?" You can do that with if (ts.touched()) © Adafruit Industries https://learn.adafruit.
PAGE 344
Capacitive Touchscreen Paint Demo This page is for the Capacitive Touch Screen version of the Shield! We now have a super-fancy capacitive touch screen version of this shield. Instead of a resistive controller that needs calibration and pressing down, the capacitive has a hard glass cover and can be used with a gentle fingertip. It is a single-touch capacitive screen only! The capacitive touch screen controller communicates over I2C, which uses two hardwire pins.
PAGE 345
Download Adafruit FT6206 Library http://adafru.it/dGH Once you have the library installed, restart the IDE. Now from the examples->Adafruit_FT6206 menu select CapTouchPaint and upload it to your Arduino. The touch screen is made of a thin glass sheet, and its very fragile - a small crack or break will make the entire touch screen unusable. Don't drop or roughly handle the TFT and be especially careful of the corners and edges.
PAGE 347
Drawing Bitmaps There is a built in microSD card slot into the shield, and we can use that to load bitmap images! You will need a microSD card formatted FAT16 or FAT32 (they almost always are by default). Its really easy to draw bitmaps. Lets start by downloading this image of pretty flowers (pix by johngineer) Copy purple.bmp into the base directory of a microSD card and insert it into the microSD socket in the shield.
PAGE 348
To make new bitmaps, make sure they are less than 240 by 320 pixels and save them in 24-bit BMP format! They must be in 24-bit format, even if they are not 24-bit color as that is the easiest format for the Arduino. You can rotate images using the setRotation() procedure You can draw as many images as you want - dont forget the names must be less than 8 characters long. Just copy the BMP drawing routines below loop() and call bmpDraw(bmpfilename, x, y); For each bitmap.
PAGE 349
Backlight & Touch IRQ Both the resistive and capacitive versions of this shield have the ability to dim the backlight and get an interrupt from the resistive or capacitive touch controller chip on-board. Controlling the Backlight By default, we assume you'll want the backlight on all the time. However, you may want to PWM control or otherwise turn off the LED backlight to save power. You can do this with a simple hack. On the back, look for the backlight jumper.
PAGE 350
Advanced users may want to get an interrupt on a pin (or even, just test a pin rather than do a full SPI query) when the touchscreen is pressed. You can do that by jumpering the #7 solder jumper labeled TS int. We didn't want it to connect to #2 or #3 since those are the Leonardo I2C pins. You can use pin change interrupts to get an interrupt callback on #7. (http://adafru.it/d4h)Or, with a little blue wire, advanced users can connect a wire from the TS interrupt pad to any pin they choose.
