august 5, 2008 document no. 38-12023 rev. *f 5 cy8c27x43 automotive data sheet psoc? overview psoc designer software subsystems device editor the device editor subsystem allows the user to select different onboard analog and digital components called user modules using the psoc blocks. examples of user modules are adcs, dacs, amplifiers, and filters. the device editor also supports easy development of multiple configurations and dynamic reco nfiguration. dynamic configu- ration allows for changing configurations at run time. psoc designer sets up power-on initialization tables for selected psoc block configurat ions and creates source code for an application framework. the framework contains software to operate the selected components and, if the project uses more than one operating configur ation, contains routines to switch between different sets of psoc block configurations at run time. psoc designer can print out a configuration sheet for given project configuration for use during application program- ming in conjunction with the device data sheet. once the framework is generated, the us er can add application-specific code to flesh out the framework. it?s also possible to change the selected components and regenerate the framework. design browser the design browser allows users to select and import precon- figured designs into the user?s project. users can easily browse a catalog of preconfigured design s to facilitate time-to-design. examples provided in the tools include a 300-baud modem, lin bus master and slave, fan contro ller, and magnetic card reader. application editor in the application editor yo u can edit your c language and assembly language source code. you can also assemble, com- pile, link, and build. assembler. the macro assembler allows the assembly code to be merged seamlessly with c co de. the link libraries auto- matically use absolute addressing or can be compiled in relative mode, and linked with other software modules to get absolute addressing. c language compiler. a c language compiler is available that supports cypress microsystems? psoc family devices. even if you have never worked in the c language before, the product quickly allows you to cr eate complete c programs for the psoc family devices. the embedded, optimizing c compiler provides all the features of c tailored to the psoc architecture. it comes complete with embedded libraries providing port and bus operations, standard keypad and display support, and extended math functionality. debugger the psoc designer debugger subsystem provides hardware in-circuit emulation, allowing the designer to test the program in a physical system while providing an internal view of the psoc device. debugger commands allow the designer to read and program and read and write data memory, read and write io registers, read and write cpu registers, set and clear break- points, and provide program run, halt, and step control. the debugger also allows the designer to create a trace buffer of registers and memory locations of interest. online help system the online help system displays online, context- sensitive help for the user. designed for procedural and quick reference, each functional subsystem has its ow n context-sensitive help. this system also provides tutorials and links to faqs and an online support forum to aid the designer in getting started. hardware tools in-circuit emulator a low cost, high functionality ice (in-circuit emulator) is avail- able for development support. this hardware has the capability to program single devices. the emulator consists of a base unit that connects to the pc by way of the parallel or usb port. the base unit is universal and will operate with all psoc devices. emulation pods for each device family are available separately. the emulation pod takes the place of the psoc device in the target board and performs full speed (24 mhz) operation.

august 5, 2008 document no. 38-12023 rev. *f 6 cy8c27x43 automotive data sheet psoc? overview designing with user modules the development process for the psoc device differs from that of a traditional fixed function microprocessor. the configurable analog and digita l hardware blocks give the psoc architecture a unique flexibility that pays dividends in managing specification change during development and later by lowering inventory costs. these configurable res ources, called psoc blocks, have the ability to implement a wide variety of user-selectable func- tions. each block has several regi sters that determine its func- tion and connectiv ity to other blocks, mu ltiplexers, buses and to the io pins. iterative development cycles permit you to adapt the hardware as well as the software. this substantially lowers the risk that you will have to sele ct a different part to meet the final design requirements. to speed the development process, the psoc designer inte- grated development environment (ide) provides a library of pre-built, pre-tested hardware pe ripheral functions, called ?user modules.? user modules make selecting and implementing peripheral devices simple, and come in analog, digital, and mixed signal varieties. the standard user module library con- tains over 50 common peripherals such as adcs, dacs tim- ers, counters, uarts, and other not-so common peripherals such as dtmf generators and bi-quad analog filter sections. each user module establishes the basic register settings that implement the selected function. it also provides parameters that allow you to tailor its precis e configuration to your particular application. for example, a pulse width modulator user mod- ule configures one or more digi tal psoc blocks, one for each 8 bits of resolution. the user module parameters permit you to establish the pulse width and duty cycle. user modules also provide tested software to cut your development time. the user module application programming interface (api) provides high- level functions to control and respond to hardware events at run-time. the api also provides optional interrupt service rou- tines that you can adapt as needed. the api functions are documented in user module data sheets that are viewed directly in the psoc designer ide. these data sheets explain the internal operation of the user module and provide performance specificat ions. each data sheet describes the use of each user module parameter and documents the set- ting of each register cont rolled by the user module. the development process starts when you open a new project and bring up the device editor, a graphical user interface (gui) for configuring the hardware. yo u pick the user modules you need for your project and map them onto the psoc blocks with point-and-click simplicity. next, you build signal chains by inter- connecting user modules to each other and the io pins. at this stage, you also configure the clock source connections and enter parameter values directly or by selecting values from drop-down menus. when you are ready to test the hardware configuration or move on to developing code for the project, you perform the ?generate applicati on? step. this causes psoc designer to generate source co de that automatically configures the device to your specification and provides the high-level user module api functions. user module and source code development flows the next step is to write your main program, and any sub-rou- tines using psoc designer?s ap plication editor subsystem. the application editor includes a project manager that allows you to open the project source code files (including all gener- ated code files) from a hierarchal view. the source code editor provides syntax coloring and advanced edit features for both c and assembly language. file search capabilities include simple string searches and recursive ?grep-style? patterns. a single mouse click invokes the build manager. it employs a profes- sional-strength ?makefile? system to automatically analyze all file dependencies and run the compiler and assembler as nec- essary. project-level options control optimization strategies used by the compiler and linker. syntax errors are displayed in a console window. double clicking the error message takes you directly to the offending line of source code. when all is correct, the linker builds a hex file image suitable for programming. the last step in the development process takes place inside the psoc designer?s debugger subsystem. the debugger down- loads the hex image to the in- circuit emulator (ice) where it runs at full speed. de bugger capabilities rival those of systems costing many times more. in addit ion to traditional single-step, run-to-breakpoint and watch-variable features, the debugger provides a large trace buffer and allows you define complex breakpoint events that include monitoring address and data bus values, memory locations and external signals. debugger interface to ice application editor device editor project manager source code editor storage inspector user module selection placement and parameter -ization generate application build al l event & breakpoint manager build manager source code generator [+] feedback [+] feedback
