RE Dynamic C is an integrated development system for writing embedded software It runs on an IBM compatible PC and is designed for use with single board computers and other devices based on the Rabbit microprocessor Chapter 4 provides the libraries function calls and sample pro grams related to the BL2100 4 1 Running Dynamic C You have a choice of doing your software development in the flash memory or in the static RAM included on the BL2100 The flash memory and SRAM options are selected with the Options Compiler menu The advantage of working in RAM is to save wear on the flash memory which is limited to about 100 000 write cycles The disadvantage is that the code and data might not both fitin RAM NOTE An application can be developed in RAM but cannot run standalone from RAM after the programming cable is disconnected Standalone applications can only run from flash memory NOTE Do not depend on the flash memory sector size or type Due to the volatility of the flash memory market the BL2100 and Dynamic C were designed to accommodate flash devices with various sector sizes BL2100s that are special ordered with 512K flash 512K SRAM memory options have two 256K flash memories By default Dynamic C will use only the first flash memory for program code in these BL2100s Uncomment the USE 2NDFLASH CODE macro within the RABBITBIOS C file in the Dynamic C BIOS folder to allow the second flash memory to hold any program code
