On Time RTOS-32 Components

On Time RTOS-32 applications always use RTTarget-32.

Components RTKernel-32, RTFiles-32, RTIP-32, RTPEG-32, and RTUSB-32 are optional.



Core Operating System and Development Tools
RTTarget-32 includes all development tools required to run 32-bit applications on an embedded system. RTTarget-32 can process an application built with a regular Win32 compiler to run on the embedded target. It provides boot code to initialise the target's hardware, a run-time library, a locator, and cross debugging support. RTTarget-32's run-time environment emulates a subset of the Win32 API.


Real-Time Scheduler
RTKernel-32 is a library with functions to create threads, semaphores, critical sections, etc. It adds most Win32 thread API functions to On Time RTOS-32's Win32 emulation.


Embedded File System
RTFiles-32 allows embedded applications to access files on diskettes, hard disks, flash disks, USB disks, CD-ROMs, and DVDs formatted with a FAT, exFAT, or ISO 9660 file system. Like RTTarget-32 and RTKernel-32, it provides its functionality through a Win32 API emulation and its own API.


Embedded TCP/IP Stack
RTIP-32 provides networking capabilities and implements the core TCP/IP protocols for Ethernet and serial communications through the Berkeley socket API. It is source code compatible with the Windows WinSock 1.1 API.


Portable Embedded GUI
RTPEG-32 is an event-driven, object-oriented C++ GUI library. It can be used to implement professional Windows look-and-feel or custom user interfaces. Device drivers for VGA and SVGA/VESA graphics hardware are included.


Real-Time Host USB Stack
RTUSB-32 is a Universal Serial Bus (USB) host stack for embedded systems. It contains the core protocol stack, host controller device drivers, a low-level communication API and high-level class drivers.
