Developing applications with embOS
embOS is available in source or object code form. Both come
with a ready-to-go start project: The first multi-task
program will be running within five minutes. The start
application and usable samples are supplied in source code
form. Libraries for all memory models and initialization of
the controller in C-source are included to tailor the
system to any application.
Profiling using embOSView
embOSView communicates with embOS running on the target
over a UART and displays all available information of the
tasks and major system variables. All communication is done
from within the communication interrupt routines. This
means that it is non-intrusive if embOSView is not
connected and minimally intrusive while embOSView is
connected. On most CPUs a profiling build of the libraries
is available. In profiling build, embOS collects precise
timing information for every task, which enables embOSView
to show the CPU load.
Zero Latency Interrupts
embOS is perfectly suited for hard real time conditions as
it does not block high priority or zero latency interrupts.
High priority interrupts do not add additional latency or
jitter from the operating system. When an RTOS modifies its
data structures, it has to block access to its data
structures. In order to achieve that, low priority
interrupts are blocked. High priority interrupts cannot
call OS functions.
A simulation environment running under MS Windows is
available. It can be used to write and test the entire
application on your PC (all routines are 100% identical to
your embedded application). This makes debugging and
development easy and convenient and saves development time.
The simulation is an open environment, which also allows
adding C-code to simulate the target specific hardware.
embOS Simulation comes with a ready-to-go start project for
MSVC, but may also be used with other tool chains. A trial
version is available upon request.
Power-Saving Tickless Mode
embOS tickless low power support reduces the power
consumption for e.g. battery powered devices. Instead of
having a timer interrupt for each system tick the timer is
reprogrammed to be able to spend as much time as possible
in low power mode.
