Is there a way to generate an assembler listing file that shows all of the compiled and assembled code after linking? I've got the option selected for Assembler-> Output list file, but that only creates a list of main.c. I need something that will show all of the SP initializing, prologue, and epilogue, etc. I've tried selecting the option for compiler-> output assembler file, but I get an error

Hi, Use the CrossWorks documentation. Perhaps a lost art, but there you go. The TI stuff is intended for assembly code use only, it isn't C callable. Therefore you will require the application of organic matte

Hello- I'm new here and wonder if anyone has MSP430 code that will convert 16-bit binary to 5 bytes of ASCII. Prefer assembler and while I'm at it I could use assembler code that does a print function thru the USART. I thought of looking at assembler listing of printf but IAR freebie software wont let me view assembled version of C . Thanks - Steve / Columbus, Ohio

Hi I am currently using the IAR Workbench (Kickstart package) to develop code for the MSP430F147. The project consists of a main C routine and a number of Assembler functions called by this main routine. As you all know, the Kickstart linker can only handle about 2k of C code which is quite limiting. The other option is to use GCC. I would like to know if it is possible to mix C and
