Hi I'm using Code Composer with an assembler only project. There is no "C" file and I've set the linker initialisation model to "none". I can download code, I can single step code from the first assembler instruction. The code "works" as far as I can tell.

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

In one of the recent TI errata (slaz033b.pdf), there is a method to un-optimize the Assembler: Quote: Note that certain assemblers may optimize an indexed addressing source operation of 0(Ry) to an indirect register mode @Ry operation, which will not work. The following is an example of reading the word memory location 0x4000 in marginal read mode, preventing a possible assembler optimi...

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.

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
