Press Release Summary:
Employing 8-channel GPIO capacitive touch key controller IC, Vinco Touch Key shield mates with Vinco motherboard in order to provide full touch pad functionality. In addition to 4 pushbuttons and 5 GPIO-controlled LED indicators, solution occupies 55.4 x 68.6 mm footprint and has 8 touch keys that employ capacitive sensing technology. Touch keys are capable of passing input data to Vinculum-II dual port USB host/device controller IC on Vinco module via I²C bus.
Original Press Release:
FTDI Adds Advanced User Interface Mechanism to Arduino-Inspired Vinco Platform
New touch-enabled shield encourages imaginative embedded system prototyping & development activities
In order to offer engineers greater scope to create ground-breaking, cost-effective system designs within a shorter period of time, USB solutions specialist Future Technology Devices International Limited (FTDI) is adding to the range of input/output application boards (or 'shields') available for its Vinco development module. The new Vinco Touch Key shield mates with the Vinco motherboard, providing it with full touch pad functionality.
Supplied in a compact form factor with dimensions of 55.4 mm x 68.6 mm (in harmony with the established format of the Arduino Duemilanove and Uno boards), and incorporating a STMicroelectronics STMPE821 8-channel general purpose input/output (GPIO) capacitive touch key controller IC, the shield has 8 touch keys which employ a capacitive sensing technology, responding to physical input stimulus from the user. It also has a set of 4 push buttons and 5 GPIO-controlled LED indicators.
The touch keys are capable of passing input data to the Vinculum-II (VNC2) dual port USB host/device controller IC on the Vinco module via an I2C bus, where it can be processed by the IC's integrated 16-bit microcontroller core. Access to the Vinco pulse width modulation (PWM) interface is also available on the header pins. The shield requires a 5V supply, which can be drawn from an external supply or through the Vinco motherboard connections.
"The Vinco platform captures the spirit of Arduino open-source model. It furnishes engineers with a unique, easy-to-use environment where they can easily create system designs that include various input methods as well as product connectivity," commented Dave Sroka, Global Product Director at FTDI, "The new Touch Key shield demonstrates the Vinco platform's ability to utilise the Android Open Accessory initiative, so that devices using the Android operating system, such as tablet PCs, can control items of external hardware through a human machine interface (HMI), over USB."
To support the Vinco platform and its expanding range of shields, FTDI offers free software libraries, drivers and source code, allowing engineers a high level of design flexibility. A comprehensive Integrated Development Environment (IDE), which includes a code editor, 'C' compiler, assembler and debugger, is also available to download for free from the company's website. Further shield introductions will be announced in the near future.
The FTDI Vinco Touch Key shield is available at a cost of $33.75 for single units.

About FTDI
Future Technology Devices International (FTDI) specialises in the design and supply of silicon and software solutions for the Universal Serial Bus (USB). FTDI offers a simple route to USB migration by combining easy-to-implement IC devices with proven, ready-to-use, royalty-free USB firmware and driver software. The company's single and multi-channel USB peripheral devices come with an easy-to-use UART or FIFO interface. These popular devices can be used in legacy USB-to-RS232/RS422 converter applications or to quickly interface an MCU, PLD, or FPGA to USB. A wide range of evaluation kits and modules are available to evaluate FTDI's silicon prior to design-in.
Vinculum is FTDI's brand name for a range of USB Host/Slave controller ICs that provide easy implementation of USB Host controller functionality within products and use FTDI's tried and tested firmware to significantly reduce development costs and time to market.
FTDI is a fabless semiconductor company headquartered in Glasgow, UK with R&D centres in Glasgow and Singapore and has regional sales offices in Oregon, USA, Shanghai, China and Taipei, Taiwan. More information is available at www.ftdichip.com
