FTDI adds touch capability to its open source platform

Future Technology Devices International (FTDI) has added a touch control input/output application boards for its Vinco development module, writes Richard Wilson.

The Vinco Touch Key applications board, which the supplier calls a shield mates with the Vinco motherboard, and incorporates 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 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," said Dave Sroka, global product director at FTDI.

The shield is supplied in a 55.4 mm x 68.6 mm  form-factor, the established format of the Arduino Duemilanove and Uno boards.

There are free software libraries, drivers and source code. An Integrated Development Environment (IDE) includes a code editor, 'C' compiler, assembler and debugger.

The FTDI Vinco Touch Key shield is available at a cost of $33.75 for single units.

The Dead Platform Graveyard - mobile lessons to learn

Falling within the purview of "good ideas, bad execution", here's an interesting article that tries to take an overview of what makes a platform fail, when it comes to mobile devices. And there have been a lot of failed platforms...

The MD of VisionMobile, Andreas Constantinou, enumerates the more than 25 platforms that could be  classed as failed, from Meego and Aria (?) to UIQ and Prism...

He begins:

2011 turned out to be open hunting season for mobile platforms, with the MeeGo, webOS and LiMo projects coming to an end.

MeeGo, webOS and LiMo, together with Windows Mobile and Symbian are just the tip of the dead OS iceberg. The last 10 years have seen numerous companies launch operating systems or platforms for mobile devices, most of which have been fallen under the media radar. The table below lists all known mobile platforms that have died or are a 'zombie' (semi-dead) state - that's all 26 of them, from Access Linux Platform to Windows Mobile.

It is worth checking out the table - The Dead Platform Graveyard - a definitive looking summary.

The platforms failed for a combination of reasons such as cost of ownership, conflicting revenue models, lack of network effects, and high adoption barriers...

For example, discussing each of these factors in turn, when it comes to "network effects, he says:

It was Apple that proved how network effects - the positive feedback loop between app developers and users - can lead to enormous demand-side economies of scale. It was the power of well-oiled network effects that made Nokia realize that "it had to go to developers" (and not wait for developers to go to Nokia) before eventually losing the Symbian battle against Android and iOS.

But enough of failure. What is the success factor of modern platforms?

Firstly, Andreas  software DNA, that is a company with resources, processes and values routed in the PC or Internet world where developers, not OEMs are the platform's primary customer. Secondly, a successful platform vendor needs to have large pockets due to the billions of dollars in investment needed to build a stable and advanced software foundation, while attracting developers to the platform. Note that the bubble size in the chart shows last relative size of 4 quarters of vendor revenues.
