6 / 44 page  CY8C21123, CY8C21223, CY8C21323 Document Number: 38-12022 Rev. *U Page 6 of 44 Development Tool Selection Software PSoC Designer At the core of the PSoC development software suite is PSoC Designer. Utilized by thousands of PSoC developers, this robust software has been facilitating PSoC designs for years. PSoC Designer is available free of charge at http://www.cypress.com. PSoC Designer comes with a free C compiler. PSoC Designer Software Subsystems You choose a base device to work with and then select different onboard analog and digital components called user modules that use the PSoC blocks. Examples of user modules are ADCs, DACs, Amplifiers, and Filters. You configure the user modules for your chosen application and connect them to each other and to the proper pins. Then you generate your project. This prepop- ulates your project with APIs and libraries that you can use to program your application. The tool also supports easy development of multiple configura- tions and dynamic reconfiguration. Dynamic reconfiguration allows for changing configurations at run time. Code Generation Tools PSoC Designer supports multiple third-party C compilers and assemblers. The code generation tools work seamlessly within the PSoC Designer interface and have been tested with a full range of debugging tools. The choice is yours. Assemblers. The assemblers allow assembly code to be merged seamlessly with C code. Link libraries automatically use absolute addressing or are compiled in relative mode, and linked with other software modules to get absolute addressing. C Language Compilers. C language compilers are available that support the PSoC family of devices. The products allow you to create complete C programs for the PSoC family devices. The optimizing C compilers provide all the features of C tailored to the PSoC architecture. They come complete with embedded libraries providing port and bus operations, standard keypad and display support, and extended math functionality. Debugger PSoC Designer has a debug environment that provides hardware in-circuit emulation, allowing you 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 I/O 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. In-Circuit Emulator A low cost, high functionality In-Circuit Emulator (ICE) is available 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 a USB port. The base unit is universal and operates 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 (24MHz) operation. Standard Cypress PSoC IDE tools are available for debugging the CY8C20x36A/66A family of parts. However, the additional trace length and a minimal ground plane in the Flex-Pod can create noise problems that make it difficult to debug the design. A custom bonded On-Chip Debug (OCD) device is available in a 48-pin QFN package. The OCD device is recommended for debugging designs that have high current and/or high analog accuracy requirements. The QFN package is compact and is connected to the ICE through a high density connector. PSoC Programmer Flexible enough to be used on the bench in development, yet suitable for factory programming, PSoC Programmer works either as a standalone programming application or it can operate directly from PSoC Designer. PSoC Programmer software is compatible with both PSoC ICE-Cube in-circuit emulator and PSoC MiniProg. PSoC programmer is available free of charge at http://www.cypress.com/psocprogrammer. |
