Add the following snippet to your HTML:. Colorful, bitdifferent shades4-wire resistive touchscreen8 bit digital interface, plus 4 control lines.

CS chip select to A3. ILI is integrated inside the display. It drives the display and has nothing to do with touchscreen Although the shield connects some pins of ILI together with pins of the touchscreen. To read a byte from ILI after sending a read command e.

Then command 0x2Ch. Then send in sequence for every single pixel in the area a value of the color to display. The color has 2 byte format. The touch screen is attached on the surface of the display. So you can't write to LCD display and read the touch screen in the same time.

Wikipedia: Touch-screen devices using resistive technology, a two-dimensional membrane potentiometer provides x and y coordinates. The top layer is thin glass spaced close to a neighboring inner layer.

The underside of the top layer has a transparent conductive coating; the surface of the layer beneath it has a transparent resistive coating. A finger or stylus deforms the glass to contact the underlying layer. Edges of the resistive layer have conductive contacts. Locating the contact point is done by applying a voltage to opposite edges, leaving the other two edges temporarily unconnected.

The voltage of the top layer provides one coordinate. Disconnecting those two edges, and applying voltage to the other two, formerly unconnected, provides the other coordinate.

Alternating rapidly between pairs of edges provides frequent position updates. An analog-to digital converter provides output data.

First we need to detect if there is a touch. Then we need to read a position of a touch. Touchscreen I tested sometimes wrongly detects a touch, outside of the touched point. To prevent this I added some delays and the X and Y analog value is read repeatedly and touch is approved only if values do not differ a lot. Please log in or sign up to comment.

EmptySet Jr. I modified an XPT library example to use my project's pins, remove the fonts, and use the adafruit library instead of whatever was default. Here's the code and pin configuration below. Code: [Select]. Re: 2. You need level shifter chip or voltage divider on every output signal. MISO does not need a shifter. But the URTouch library abuses this line. It all becomes very messy with jumper wires and breadboards.

Invest in a proper 3. Zero, Due, I use Seeeduino switched to 3. Some of the newer Chinese Uno clones have a 3. The Nano is always 5V. You end up with something bulky, unreliable and expensive.

Making you wonder why you were such a cheapskate buying the Nano in the first place. You need seven 3. Use a 2k2 series resistor for MISO. The updated connections are as follows: Code: [Select]. However TSX level shifter or straight 3. So you can have as many devices on the bus as you want.

So it should not matter how many Slaves are connected to the bus. So it is important than inactive devices put MISO into 3-state.

What were your results? The code compiled but the only error I got was "cannot start touch screen" and I couldn't find many references online. However, I was able to get working results a few hours ago. I stumbled across this page and this helped me get the wiring set up correctly. I'll update the main post with details.
