STM8处理器特点 通用特点 Max fCPU: Up to 24 MHz。 1.6 cycles/instruction。 up to 128 Kbytes Flash。 up to 2 Kbytes true data E2PROM。 up to 6 Kbytes。 Up to 70 user I/Os。 STM8处理器特点 STM8处理器特点 MEMORY MAP 开发工具 软件： 编译器：CXSTM8(cpstm8, cgstm8, costm8, castm8) 连接器：CLNK 编程支持工具：chex，clabs，clib，cobj，cv695，cvdwarf 调试器：ST Visual Develop 编程器：ST Visual Programmer 硬件： 仿真器Rlink 仿真器STICE CXSTM8 Compiler Architecture(CXSTM8)： cpstm8：the C preprocessor and language parser. cpstm8 expands directives in your C source and parses the resulting text. cgstm8 - the code generator. cgstm8 accepts the output of cpstm8 and generates assembly language statements. CXSTM8 costm8 - the assembly language optimizer. costm8 optimizes the assembly language code that cgstm8 generates. castm8 - the assembler. castm8 converts the assembly language output of costm8 to a relocatable object module. CLNK CLINK clnk combines all the object modules that make the appropriate modules from the C library. PROGRAMMING 编程支持工具: chex - absolute hex file generator. clabs - absolute listing utility. clib - build and maintain object module libraries. cobj - object module inspector. cv695 - IEEE695 format converter. cvdwarf - ELF/DWARF format converter. COMPILER File Naming Conventions COMPILER Memory Models Zero Page：0x00~0xff, more efficient than Long Range variables. long range：0x100～17ff。 COMPILER Step 1: Compiling cxstm8 [options] files.[c|s] Step 2: Linking clnk [options] file.lkf [files] Step 3: Generating hex file chex [options] file Step 4: Generating updata file COMPILER BUILD.BAT cxstm8 [options]: -l :create listing +debug :produce debug information +modsl :select the Stack Long mode. +warn :enable warnings. +strict :enforce stronger type checking. COMPILER –ce*:specify a path for the error files. -e :log errors file. –t* :specify path for temporary files. -co*:specify a path for the object files. CLNK Clnk option: -bs# :bank size -m* :map file name
