embOS & emWin Harmony
SEGGER has worked closely with Microchip to
integrate seamlessly our RTOS embOS and
Graphics Package emWin within the Microchip
Harmony environment.
This allows Harmony users to get up and running
with SEGGER software on their target hardware
quickly and painlessly. Both embOS and emWin
also offer advanced features that may be taken
advantage of outside of the Harmony environment.

embOS Real-time Operating System
•  20 years in the market
•  Profiling support
•  Low Power Tickless support
•  µsec precise system time
•  True Zero interrupt latency
•  Sample start projects
•  Full Source code available
•  Very low resource usage
•  No compile-time configuration needed
embOS is a priority-controlled real time operating system, with zero interrupt latency, high-
performance, and is optimized for minimum memory consumption in both RAM and ROM.

embOS Low Power Tickless Operation
Tickless low power support reduces power consumption, especially useful for
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.
How to use it
Tickless support can be added to any embOS start project. The embOS tickless
support is based on the three new API functions OS_GetNumIdleTicks(),
OS_StartTicklessMode and OS_AdjustTime().
In order to use the tickless support the OS_Idle() function has to be modified
and a callback function has to be implemented. The tickless OS_Idle() function
calculates the amount of time which should be spent in low power mode and
reprograms the timer accordingly. The callback function is called automatically
from the scheduler when the low power period ended. It adjusts the system
time and resets the timer to it's default tick time.

embOS µsec Precise System Time
This is a unique feature of embOS. In other systems, RTOS-
based time functions are based on the system tick which is
typically 1 msec or more. This makes it impossible to get
very precise timing values.
embOS supports the API function OS_GetTime_us() to get
the current system time in micro second resolution. This
feature is easy to use and can be used with any embOS
start project.
The start projects have to set up this feature with a simple
API call ofOS_Config_SysTimer(). This is already done for
the most of the embOS start projects and can be done for
any other embOS start project by Segger on request.
How to use it
OS_GetTime_us() can be called from any location in your
application code. It can be used in main, tasks, software
timers and interrupt functions.
Sample application
void MyFunction(void) {
OS_U32 tStart;
OS_U32 tEnd;
OS_U32 t;

tStart = OS_GetTime_us();
DoSomeThing()
tEnd = OS_GetTime_us();
t = tStart -‐‑ tEnd;
printf("ʺTime to run the function: %u"ʺ,
t);
}

emWin Embedded Graphics
Package
emWin has quickly established itself as the industry standard for
embedded graphics. It is designed to provide an efficient, processor
independent, LCD controller independent, Graphical User Interface (GUI)
for any application that operates with a graphical LCD.
•  Complete ANSI "C" Code; No Need for C++
•  RTOS Independent (embOS Available)
•  Can Run Without an RTOS (Superloop)
•  Only Hardware Dependent Portion is the LCD Driver
•  GUIBuilder Drag and Drop Design Interface
•  Multi-touch support enabling pinch, zoom, rotate gestures, and
up to 10 touch points
•  Includes complete font set and Font Converter

emWin GUIBuilder & Simulation
Menu Bar Widget Selection Bar

Editor
emWin GUIBuilder
emWin’s GUIBuilder is an easy to use drag-and-drop design
interface. Easily layout your application then generate “C” code.
This code may be edited and read back into the GUIBuilder for a
streamlined design experience.
emWin’s PC Simulation allows you to design the user interface on
your PC (no hardware required!). You may debug the user interface
program and create demos of your application, which can be used
to discuss the user interface. The resulting executable can be sent
easily via email.

emWin Extensive Samples
PIC32 Demo Board BSPs Available
The Sample directory contains ready-to-go examples that demonstrate different features of emWin and provide examples of
some of their typical uses. In order to build any of these executables, their C source must be .activated. in the project. This is
easily done. https://www.segger.com/emwin-samples.html

Head of Engineering

•  Extensive RTOS Ecosystem, building upon FreeRTOS with OPENRTOS &
SAFERTOS
•  FreeRTOS top-in-class in the 2011, 12, 13 & 14 in EETimes embedded
systems surveys in two areas:
•  “RTOS currently used”
•  “RTOS considered for the next project”
•  OPENRTOS supports 34 processor architectures and 18 toolchains
•  Free/OPENRTOS has millions of product deployments
•  SAFERTOS is the first RTOS to be pre-certified to IEC 61508 Safety
Integrity Level 3 by TÜV SÜD, the highest possible for a software only
component
•  SAFERTOS was the first pre-certified safety critical RTOS to be ROM’ed
in a main line processor by Texas Instruments
