QNX Driver Development Kit 

§1. Short description

To facilitate and standardize the task of driver creation for data acqusition devices the company RTS-Ukraine offers an integrated DWizard drivers development environment. This  environment represents convenient user interface for creation, debugging and integration of a driver created to Silver 2 package. All the programmer has to do is to instrument interface with particular hardware.

§2. Short characteristics

  • Most assemblies types: ISA, PCI, sequential port and others (drawing 1);
  • Debugging;
  • Visual driver creation and editing possibility (drawing 6);
  • integration into a Silver 2 package

§3. Basic points

Interaction of user software with a driver is shown on the following drawing:

User software using access library interface conducts a driver enquiry. The driver kernel using equipment inquiry functions provides data access. Equipment inquiry functions may be instrumented with a help of DWizard.

Data accessible to user application is represented on 'Data channels' of different types. There are 5 types of channels at all: analog input/output channel, discreet input/output channel and complementing input channel.

Each data channel is characterized with a number of parameters: access type (input/output), channel type (analog, discreet), signal scale and others:
