User’s Manual 415. S OFTWARE REFERENCEDynamic C is an integrated development system for writingembedded software. It runs on an IBM-compatible PC and isdesigned for use with Rabbit controllers and other controllersbased on the Rabbit microprocessor. Chapter 5 describes thelibraries and function calls related to the RCM3365/RCM3375.5.1 More About Dynamic CDynamic C has been in use worldwide since 1989. It is specially designed for program-ming embedded systems, and features quick compile and interactive debugging. A com-plete reference guide to Dynamic C is contained in the Dynamic C User’s Manual.You have a choice of doing your software development in the flash memory or in the staticSRAM included on the RCM3365/RCM3375. The flash memory and SRAM options areselected with the Options > Program Options > Compiler menu.The advantage of working in RAM is to save wear on the flash memory, which is limitedto about 100,000 write cycles. The disadvantage is that the code and data might not bothfit in RAM.NOTE: An application should be run from the program execution SRAM after the serialprogramming cable is disconnected. Your final code must always be stored in flashmemory for reliable operation. RCM3365/RCM3375 modules running at 44.2 MHzhave a fast program execution SRAM that is not battery-backed. Select Code andBIOS in Flash, Run in RAM from the Dynamic C Options > Project Options >Compiler menu to store the code in flash and copy it to the fast program executionSRAM at run-time to take advantage of the faster clock speed. This option optimizesthe performance of RCM3365/RCM3375 modules running at 44.2 MHz.NOTE: Do not depend on the flash memory sector size or type in your program logic.The RCM3365/RCM3375 and Dynamic C were designed to accommodate flashdevices with various sector sizes in response to the volatility of the flash-memorymarket.Developing software with Dynamic C is simple. Users can write, compile, and test C andassembly code without leaving the Dynamic C development environment. Debuggingoccurs while the application runs on the target. Alternatively, users can compile a programto an image file for later loading. Dynamic C runs on PCs under Windows 2000/NT andlater—see Rabbit’s Technical Note TN257, Running Dynamic C ® With Windows Vista ®,
