Use TCESession to initialize connection with remote PPC computer via serial or network. After connection you can make RAPI functions calls.

TCETable introduces the interface similar to Delphi TDataSet for the RAPI databases with analog of TField called TCEProp. Populate TCETable component with RAPI database structure automatically during design time in Delphi IDE. High-level methods UploadTable and DownloadTable will make an easy transfer of TDataSet descendant's to/from PPC machine.

DDObjects doesn't mimic other implementations as DCOM or Corba, which are generalized to a least common denominator, but makes use of Delphi's rich type system including Objects, Exceptions, Records, Sets and Enumerations.

DDObjects allows integration of 3rd party socket libraries. Borland Socket Components as well as Synapse, Indy 9 and Indy 10 are supported which due to their pluggable architecture allows DDObjects to take advantage of SSL encryption and security.

Beneath some bugfixes and enhancements Version 1.1.5 adds support fo HTTP protocol.

DDObjects is available for Delphi 5-7, Delphi 2005-2007, C++ Builder 6 and 2006 and Kylix 3. A preeview for DDObjects for FreePascal is contained.

System requirements and dependencies:

• Win32 (NT/2003/XP/7/8) ... 64-bit is not tested.
• The presence of sound card
• Module and a module for non-commercial use compiled for IDE Delphi 2010 and TurboDelphi-Lite (over BDS-2006)
• Module for commercial use are available on request
• DTMFW - is an expanded version of the library, published in zh.Radiolyubitel, Minsk, 2009, ¹ 3, p.32-36. Basic version available here.

The library provides:

• Encoding (generation) and decoding DTMF signals (DTMF) realtime (with sound card) and offtime (from files WAV/MP3).
• Spektroanaliz (using FFT) realtime and offtime (from files WAV/MP3/SHARC).
• Realtime oscilloscope and offtime (data from files WAV/MP3/faylov SHARC).
• The multiplication of the spectra obtained at the window: rectangular (level 0 dB), Hemming (-54 dB), Blackman-Harris (on levels -61 dB, -67 dB, -92 dB).
• Analysis of the average noise level in the spectrum realtime and offtime.
• The detection of the amplitude and frequency of the pitch (harmonics) in the spectrum.
• Measurement of the current level of the signal amplitude with a recording device by default.
• Detection (trigger silence) exceeded the threshold level of the signal c adjustable threshold level signal and off-delay n [ms], and the ability to record fragments of audio file formats including WAV PCM.
• Hardware and software random number generation (RNG) based on a sound card c opportunity to file archiving and retrieval issue in real time.
• Analysis of the statistical distribution of data sample RNG realtime.
• Generate a sinusoidal signal with set frequency and duty cycle.

Just drop in Delphi, set some property, and run. See Demo folder for example program.
