CY8CTST120 document number: 001-46932 rev. *b page 6 of 32 designing with user modules the development process for the psoc device differs from that of a traditional fixed function microprocessor. the configurable analog and digital hardware blocks give the psoc architecture a unique flexibility. it pays di vidends in managing specification change during development and by lowering inventory costs. these configurable resources, called psoc blocks, have the ability to implement a wide variety of user-selectable functions. each block has severa l registers that determine its function and connectivity to other blocks, mu ltiplexers, buses and to the io pins. iterative development cycl es permit you to adapt the hardware and the software. this substantially lowers the risk of having to select a different part to meet the final design require- ments. to speed the development process, the psoc designer ide provides a library of pre-built, pre-tested hardware peripheral 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 contains over 50 common peripherals such as adcs, dacs timers, counters, uarts, and other not-so common peripherals such as dtmf generators and bi-quad analog filter sections. each user module establishes t he basic register settings that implement the selected function. it also provides parameters that allow to tailor its precise configuration to a particular application. for example, a pulse width modulator user module configures one or more digital psoc blocks, one for each 8 bits of resolution. the user module parameters permit to establish the pulse width and duty cycle. user m odules also provide test ed software to cut 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 rout ines that are adapted as needed. the api functions are document ed 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 specificatio ns. each data sheet describes the use of each user module parameter and documents the setting of each register controlled 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. pick the user modules you need for your project and map them onto the psoc blocks with point-and-click simplici ty. next, build signal chains by intercon- necting user modules to each other and the io pins. at this stage, 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, perform the ?generate application? step. this causes psoc designer to generate source code that automatically configures the device to your specification and provides the high level user module api functions. figure 4. user module/source code development flows the next step is to write the m ain program and any sub-routines using psoc designer?s application editor subsystem. the appli- cation editor includes a project m anager that allows to open the project source code files (including all generated 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 professional-strength ?makefile? system to automatically analyze all file dependencies and run the compiler and assembler as necessary. project-level options control optimization strategies used by the compiler and linker. syntax errors are displayed in a console window. double click the error message to view 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 downloads the hex image to the ic e where it runs at full speed. debugger capabilities rival those of systems costing many times more. in addition to traditional single-step, run-to-breakpoint and watch-variable features, the d ebugger provides a large trace buffer and allows you define complex breakpoint events such as 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 all event & breakpoint manager build manager source code generator [+] feedback
