TrueTouch Tools: Simplifying the Design Process
Cypress provides the tools you need to complete a capacitive touchscreen design from concept through mass production. Evaluation kits (EVKs) and development kits (DVKs) allow you to quickly assess solution performance, while manufacturing test kits (MTKs) and programming and debugging tools help you bring designs to production. TrueTouch Host Emulator (TTHE) software enables you to configure and tune your design, and supports all register-configurable TrueTouch products (Gen4 and later products). TrueTouch Driver Android (TTDA) is a software driver available from Cypress that allows you to integrate your touchscreen design in your end product running an Android operating system. Cypress touch controllers can interface to the latest processors from Qualcomm, Intel, nVidia, Mediatek, and others through the available software drivers.
TrueTouch Kits
Cypress offers EVKs and DVKs so you can evaluate, prototype, and debug complete designs. Kits are available for each product family to support your design. In addition, we offer the Cypress MTK to help you test your sensor hardware both in the prototype and mass production phases; and the TT Bridge Development Kit to program and debug hardware and firmware designs. See the list below for links to our kits.

TrueTouch Host Emulator Software
Cypress's TrueTouch Host Emulator (TTHE) is a PC-based software application that allows you to design, configure, tune, and debug TrueTouch solutions. It reduces design cycle time by eliminating the need to manually compile source code, generate a firmware image, and program the device. TTHE supports all register-configurable TrueTouch products. It interfaces with the controller in one of two ways:
- TrueTouch Bridge: Hardware that connects a TrueTouch controller on a PCB or an FPC to a host PC running TTHE. This supports prototyping and early stages of development.
- Mobile Tuner: Software that connects a TrueTouch-powered end product to a host PC running TTHE, either by USB or wireless connection. This provides a non-intrusive method to configure, tune, and debug TrueTouch controllers in WiFi-capable production devices.

TrueTouch Drivers
Cypress's TrueTouch® drivers are easy-to-integrate, high-performance, extensible software drivers that interface between the TrueTouch controller and a touchscreen device's operating system to accurately report touch input. Cypress provides its TrueTouch Driver for Android (TTDA), which is also part of the Linux Kernel mainline.
TTDA allows Android and Linux operating systems to recognize input from advanced features like passive stylus and hover.
