This example describes how to use the ADC and DMA to transfer continuously
converted data from ADC to a data buffer.
The ADC is configured to converts continuously ADC channel14.
Each time an end of conversion occurs the DMA transfers, in circular mode, the
converted data from ADC1 DR register to the ADC_ConvertedValue variable.
The ADC1 clock is set to 14 MHz.
Handheld designers often grapple with ways to de-bounceand control the on/off pushbutton of portable devices.Traditional de-bounce designs use discrete logic, fl ipflops, resistors and capacitors. Other designs includean onboard microprocessor and discrete comparatorswhich continuously consume battery power. For highvoltage multicell battery applications, a high voltageLDO is needed to drive the low voltage devices. All thisextra circuitry not only increases required board spaceand design complexity, but also drains the battery whenthe handheld device is turned off. Linear Technology addressesthis pushbutton interface challenge with a pairof tiny pushbutton controllers.
bulk endpoint endless source/sink firmware.
EP2OUT will always accept a bulk OUT
EP4OUT will always accept a bulk OUT
EP6IN will always return a 512 byte packet. The packet contains an
incrementing byte starting at 0x02. Since EP6 always returns a 512
byte packet, this endpoint should never be accessed except with a
high-speed host controller.
EP8IN will continuously return the packet most recently written to
EP4OUT
Writing this book was hard work, but also a lot of fun. Thanks to everyone who made it
possible, especially Jinny Verdonck, Thomas Kraft, Ricky Nkrumah, Kirk Bateman, and the
whole Apress crew. A big thanks goes also to the community that continuously extends and
improves J2ME Polish!
ET++ is a portable and homogenous object-oriented class library integrating user
interface building blocks, basic data structures, and high level application framework
components. ET++ eases the building of highly interactive applications with consistent
user interfaces following the direct manipulation principle. The ET++ class library is
implemented in C++ and can be used on several operating systems and window system
platforms. Since its initial conception the class library has been continuously
redesigned and improved. It started with an architecture which was close to MacApp.
During several iterations a new and unique architecture evolved. A byproduct of the
ET++ project is a set of tools, which were designed to support the exploration of ET++
applications at run-time.

A fourier filter for time-series signals. Does not
require the Signal Processing Toolbox.
There is an interactive version with sliders that
allow you to adjust the filter parameters
continuously while observing the effect on your signal
dynamically.
Interactive smoothing for time-series signals, with sliders that
allow you to adjust the smoothing parameters continuously
while observing the effect on your signal dynamically. Run
SmoothSliderTest to see how it works.
