51 Tracer 8051 mcu Development Board Description: Integrated Development Environment to edit,build,download,simulate and debug within the same program. Debugging of 8051 programs in C,Assembly or mixed level. Debugged program can be simultaneously viewed in C and Assembly. Variable window to watch C variable names,values and addresses. Register window to watch the special function registers including 8051 ports. Memory window to watch and modify program memory and internal RAM. Call stack window to view list of function calls that lead to current program line(traces all jumps and calls) Terminal window to monitor 8051's serial port Output Window Debug Tab to watch debug messages Fully customizable window layout with dock able or floating debug windows. Stop Debugging button to stop Debugging at any point Go button to start execution Step Into and Step Over buttons to single-step through the source code at C or Assembly level Unlimited number of breakpoints to stop execution at any C or Assembly source line. Windows 95\/98\/ME,NT,2000\/2003 and XP compatible Multi-file Editor to create and modify C or Assembly source code while simulating. Supports Micro C for 8051\/52. Feature : Source level debugging for ASM &C compilers from Raisonance,Keil,IAR and others. Automatic switching between H\/W and S\/W breakpoints. Statistical Execution Profiler identifies frequently executed code with direct link to source code. In-line symbolic assembler and dis-assembler. Step-into,step-over and step-out of functions in C and ASM level. Command mode window with macros(scripts) for automated testing. Built-in diagnostic tests to ensure system integrity. Symbol Explorer browser to locate variables in modules and functions. Drag and Drop variables and addresses between windows for easier and faster viewing. Automatic variable value pop-ups in Source window. Locals and Global variable Watch windows with all complex types support(arrays,structures,unions,etc.). Main functions : USB(Full Speed 2 M bits\/s)Real time background debugging Built in over-voltage\/short circuit monitor Firmware upgradeable from PC Totally enclosed Diagnostic LEDs(Power,Busy,Error) Reading\/Writing memory space and EEDATA areas of target microcontroller Erase of program memory space with verification Peripheral freeze-on-halt stops timers at breakpoints Built-in USB Reset self-reconnected function. High reliably ICs and Components. Compact design with mounting hole. Increased overcurrent protection Increased electrostatic protection Increased User Board first opened power protection Increased Users Board Overvoltage Protection The 51tracer Debugger connects using USB between the design engineer's PC operating with keil uv2 and their product boa
