6 / 43 page CY8C20X36A/46A/66A/96A Document Number: 001-54459 Rev. *E Page 6 of 43 Designing with PSoC Designer 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 that pays dividends 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. The PSoC development process is summarized in the following four steps: 1. Select components 2. Configure components 3. Organize and connect 4. Generate, verify, and debug Select Components PSoC Designer provides a library of prebuilt, pretested hardware peripheral components. These components are called user modules. User modules make selecting and implementing peripheral devices simple, and come in analog, digital, and programmable system-on-chip varieties. Configure Components Each of the components you select establishes the basic register settings that implement the selected function. They also provide parameters and properties that allow you to tailor their precise configuration to your particular application. For example, a Timer User Module configures one digital PSoC block. The user module parameters permit you to establish the period, mode, and timer clock. Configure the parameters and properties to correspond to your chosen application. Enter values directly or by selecting values from drop-down menus. User modules are documented in datasheets that are viewed directly in PSoC Designer. These datasheets explain the internal operation of the component and provide performance specifications. Each datasheet describes the use of each user module parameter and other information you may need to successfully implement your design. Organize and Connect You build signal chains by interconnecting user modules to each other and the I/O pins. You perform the selection, configuration, and routing so that you have complete control over the use of all on-chip resources. Generate, Verify, and Debug When you are ready to test the hardware configuration or move to developing code for the project, you perform the ‘Generate Configuration Files’ step. This causes PSoC Designer to generate source code that automatically configures the device to your specification and provides the software for the system. Based on your design, software is generated. Application programming interfaces (APIs) are provided with high level functions to control and respond to hardware events at run time and interrupt service routines that you can adapt as needed. A complete code development environment allows you to develop and customize your applications in C, assembly language, or both. The last step in the development process takes place inside PSoC Designer’s Debugger (access by clicking the Connect icon). PSoC Designer downloads the HEX image to the ICE where it runs at full speed. PSoC Designer debugging capabilities rival those of systems costing many times more. In addition to traditional single-step, run-to-breakpoint and watch-variable features, the debug interface provides a large trace buffer and allows you to define complex breakpoint events that include monitoring address and data bus values, memory locations and external signals.
