10x15 channel touch panel for placement on 4.3" LCD displays

Introduction

Integration

The IQS550 is a capacitive sensing controller

designed for multi-touch applications using

projected capacitance touch panels. This IC

is at the heart of this touch screen solution.

The main features include the 4.3”

Touchscreen Panel with a 3584 x 2304

Start by connecting the capacitive touch

panel to the module board. Add a power line

to the +3V3 pad and a reference ground to

GND. Add 3 more lines to SCL, SDA and

RDY for clock, data and ready lines. Connect

these wires to a master that communicates

with this I²C slave device. Add

Operation

Characteristics

The IQS550 requires a master

device for reading the following

touch point data over I²C:

The touch panel should only be used on 4.3”

LCD displays. To install, remove rear

performance with a custom master device or

the Azoteq CT210 USB device.

The solution can simply be powered and

touch data read at a rate of up to about 80

Hz. No special pre-configuration routines are

required. Example code is available within the

Evaluation and debugging

It is recommended to evaluate a solution

using the Azoteq CT210. The USB

device communicates via I²C with

the module board. Use this method

to evaluate performance and

explore the vast amount of custom

settings available on the IQS550.

The standard IQS5xx GUI may be

used while consulting the AZD070

User Configurable Options

Various settings can be changed

on the IQS550 through I²C. See

the example code for popular and

common adjustments. For a full

set of adjustments consult the

IQS550 datasheet (IQS5xx-A000
