Introduction
INTRODUCTION
ST-Realizer Windows CASE tool that enables develop high-quality applications ST62 families microcontrollers. Using ST-Realizer, design your application drawing symbols wiring them together. Each symbol represents process, such adding values, linked ST62 assembly code macro. wires represent flow data, linked variables constants. attach attributes symbols wires, order attach extra characteristics them. example, attaching attribute type UINT wire defines value capacity that unsigned integer 65536). When using ST-Realizer, design your application schemes. scheme like scheme which place symbols draw wires. Each application designed scheme. Schemes include subschemes, which contain further symbols wires displayed main scheme symbol, thus saving space main scheme making easy reuse processes. relationship between scheme subscheme same that directory subdirectory. Once have designed your application using ST-Realizer, analyze compile using ST-Analyzer. ST-Analyzer performs following tasks: analyzes your scheme creating netlist, creating cross references, analysing generating final code. Providing fatal errors encountered, ST-Realizer generates non-compiled ST62 macro-assembler language (.asm) file from scheme. Generates compiled binary ST62 executable file. When analyze process been successfully completed, report file generated. This report file gives information about designation pins, list variables used type memory space required application. Once have compiled your application, ST-Simulator simulate behaviour, generate view input signals, monitor signals that generated your application, fine-tune necessary. design simulation environments same that design schemes, except design held what called simulation environment files. provide with greater flexibility, create edit your symbols using ST-Symbol Editor. create symbol drawing shape, placing pins that represent variables that input output from process defining, then linking macro represents.

TUTORIAL
following tutorial designed help fully understand both principles behind creating applications using ST-Realizer create applications using ST-Realizer. this tutorial you're going create your microcontroller application. application manages battery charger. application starts charging battery when start button activated, charges battery high charge depending current state charge battery timer. application stand-alone mode using ST6265 microcontroller. also driven ST622X, ST624X, ST626X Starter Kits. NOTE: step-by-step instructions this tutorial describe operate ST-Realizer using default toolbar setup. while doing this tutorial, cannot find button that shown instruction, refer "Available Toolbar Buttons" page find which menu commands correspond that button. Setting Your Project this part tutorial will: Create project file battery charger application. Create scheme which you'll draw application. Define microcontroller which application will loaded. 3.1.1 Creating Project File Each application design stored project. Each project directory. ST-Realizer stores files that comprise application project directory. When create project specify holding directory. ST-Realizer then creates project.ini file, that contains project-specific path settings, project's scheme names compiler settings. Once you've defined your project, you'll able open scheme start designing your application. File menu, click project. project dialog opens:

Designing Application charger application, microcontroller will require following inputs outputs: analog inputs: Imax, which maximum current. Icharge, which charging current. Vcharge, which voltage output battery cell connection. digital input that connected start button. digital outputs switch between charge HIGH charge currents. digital outputs three LEDs indicate charger status. overall management charger carried state machine. This tests predefined conditions, performs action when pre-defined condition met. charger application will have following state/action definitions:
State HIGH READY Action Starts charging battery high charge switches high charge LED. Starts charging battery charge switches charge LED. Switches flashing indicating that charge finished.
Drawing Software Schemes this part tutorial, going learn: place symbols. edit symbols. design applications using ST-Realizer. What principal symbols when them. connect pins. application made four principal schemes: State Machine, which heart charger application. analyzes signals that input microcontroller, defines which signals going output external input conditions, that conditions that transmitted application from external sources, such battery voltage. external output actions, that actions that output from application, such switching LED.

ST-Realizer enables existing symbols create composite symbol. Composite symbols useful cases: When page designing starts running space. When you've designed part scheme that want reuse. design composite symbols subschemes. subscheme scheme that attached main root scheme. relationship between scheme subscheme same that directory subdirectory. Designing subscheme different from designing ordinary scheme, with exception: subscheme connections root scheme subscheme symbol. subscheme symbols named sssi_o, where indicates number inputs need your symbol number outputs. example, sss2_1 subscheme with inputs output. When want subscheme, must therefore first think about connections: what inputs does subscheme need deliver output. When know this, choose correct subscheme symbol from main library. After you've placed subscheme symbol, into subscheme double-clicking symbol start designing should start connecting subscheme ports: these transmit data between root scheme subscheme. Once you've placed ports insert existing symbols into subscheme, wire ports symbols together.

When execute analysis compile, ST-Analyzer analyzes scheme creating netlist, creating cross references, analysing generating final code. During these phases, connections between symbols, assignments variable types checked before generating source code. Providing fatal errors encountered, ST-Realizer generates non-compiled macro-assembler language (.asm) file from scheme. ST-Analyzer then generates binary code. This process runs STMicroelectronics assembler. Depending whether included (see "Disabling ROS" page 93), file with extension *.hex respectively generated. *.hex file directly loaded into while must link *.obj file with another program. When analyze process been successfully completed, report file generated.
