11 Introduction 11

12 Micriµm at a Glance Founded in 1999 by Jean Labrosse, developer of µC/OS, µC/OS-II, and µC/OS-III Headquarters in Weston, FL (USA), with a second office in Montréal, QC (Canada) Mission is to provide high-quality, well-documented software to the embedded community Micriµm is truly “for the way engineers work” With Micriµm’s products, embedded software developers have a clear time-to-market advantage 12

13 Micriµm’s Software Components µC/OS-II and µC/OS-III Real-Time Kernels µC/OS-MMU and µC/OS- MPU Kernel add-ons µC/FS File system module µC/GUI Graphical software for embedded systems µC/TCP-IP Highly dependable TCP/IP stack 13

14 Micriµm’s Software Components (Cont.) µC/USB Device and µC/USB Host Versatile USB stacks µC/CAN Robust CAN stack µC/Modbus High-quality implementation of the Modbus protocol µC/FL Easy-to-use bootloader µC/BuildingBlocks µC/Shell µC/CRC µC/Clk µC/LCD 14

15 Seeing Inside Embedded Systems

16 LEDs Simple visual indication of an application’s progress Feedback is binary Application code must be instrumented Simple drivers required 16

17 printf() Detailed information can be displayed Feedback is in text form Application code must be instrumented Performance and memory footprint may be negatively impacted (Heisenberg effect) 17

18 Graphical Displays Feedback can take the form of words or pictures Application code must be instrumented Support code is not trivial 18

19 Debuggers Typically provide access to variables through a watch window Variables are displayed as text Updates occur only at breakpoints Heisenberg effect is often significant 19

20 µC/Probe Continuous feedback is provided through a rich graphical interface Application code does not need to be instrumented No special hardware needed Little or no impact on the performance of the target system 20

21 µC/Probe Features

22 Reading Variables Access to any variable (with the exception of local or automatic variables) Variables can easily be selected for monitoring via a list Values can be displayed graphically or as text 22

23 Recording Data Any variable that can be monitored can also be logged Data is logged into a simple text file Speed at which data is logged depends on µC/Probe’s connection to the target 23

24 Writing Variables Variables can be written as the target runs Text-based and graphical means of manipulating variables are available 24

25 Graphical Interface µC/Probe can be used to create a custom graphical interface for an embedded system No programming is necessary Developers can simply drag and drop components onto data screens 25

26 Non-Intrusive Debugging µC/Probe gathers data from running embedded systems Effects on the behavior of application code are minimal Changes to a user interface created in µC/Probe do not necessitate changes to application code 26

27 Support for Almost Any MCU µC/Probe was designed to be a universal tool Micriµm’s customers have used µC/Probe with a wide variety of hardware platforms CPU architecture is not an issue 27

28 Popular Communication Protocols µC/Probe can connect to a target via RS-232, USB, or TCP/IP Device drivers are required on the embedded side No special debug hardware is needed 28

29 Compatibility with Other Tools µC/Probe accepts an executable file as input Any compiler that produces executable files of the ELF format can be used with µC/Probe In many cases, µC/Probe can be used simultaneously with other tools 29

30 Kernel Awareness µC/Probe is a perfect match for Micriµm’s newest kernel µC/OS-III µC/OS-III data screens are provided with µC/Probe Since it is a universal tool, µC/Probe is not dependent on any kernel 30

31 Free Evaluation Two evaluation versions of µC/Probe are available from Full-featured, 30-day evaluation version 5-symbol evaluation version (no time limit) The 5-symbol version allows the use of kernel awareness Free µC/Probe licenses are available to FAEs 31

32 µC/Probe from the User’s Perspective

33 µC/Probe Views µC/Probe users can switch between two different views Design View facilitates the development of a user interface Graphical components can be dragged and dropped onto data screens In Run-Time View, the interface becomes active µC/Probe updates components with values gathered from a running embedded system 33

34 Design View 34 Data screen Symbol Browser Workspace Explorer Program Options Start Button Toolbars

35 Graphical Components 35

36 Configuring Components Each graphical component is configurable What characteristics can be configured varies from component to component 36

37 µC/Probe Options The Options dialog allows the communication protocol to be specified Each protocol has its own configurable parameters 37

38 How µC/Probe Works

39 Implementation Overview µC/Probe is made up of two components A Windows program that serves as a customizable interface to running embedded systems Embedded code that responds to requests from the Windows program 39 PC Embedded Target RS-232, TCP/IP, or USB

40 Communicating with the Target µC/Probe users associate variables with graphical components in the Design View 40 PC Embedded Target RS-232, TCP/IP, or USB App_FileSel

41 … 0x App_FileSel … Communicating with the Target (Cont.) The ELF file supplied to µC/Probe as input lists the address of each variable 41 PC Embedded Target RS-232, TCP/IP, or USB Example.out

42 µC/Probe uses these addresses to formulate read and write requests Communicating with the Target (Cont.) 42 PC Embedded Target RS-232, TCP/IP, or USB Read 0x

43 The requests are sent to the target in packets Communicating with the Target (Cont.) 43 PC Embedded Target RS-232, TCP/IP, or USB Read 0x

44 Communicating with the Target (Cont.) µC/Probe updates graphical components based on the target’s responses to the requests 44 PC Embedded Target RS-232, TCP/IP, or USB Value at 0x : 0x

45 Target-Resident Code The target-resident code can be divided into two groups Hardware-independent code Device drivers and protocol stacks The hardware-independent portion of the target-resident code has a tiny footprint A few kBytes at the most The amount of additional code required depends on the communication protocol being used 45

46 Update Rates The speed at which requests are sent from the PC to the target varies according to communication protocol Via µC/Probe’s Options dialog, the delay between requests can be adjusted 46 Communication Method Transmission Speed RS-232 1,000 symbols/second TCP/IP11,000 symbols/second USB 4,000 symbols/second

47 When to Use µC/Probe

48 Debugging µC/Probe can be used to supplement a conventional debugger Especially helpful for detecting stack overflows Kernel awareness aids in debugging µC/OS-III-based applications 48

49 Demonstrations µC/Probe facilitates the development of eye-catching presentations No on-board display hardware is needed for a µC/Probe- based presentation Presentations are highly portable 49

50 Demonstrations (Cont.) 50

51 In the Field µC/Probe is not solely a development tool Technicians can use µC/Probe to gather status information from a product Product performance is usually not affected by target- resident code 51
