Hi I have read the manual and I cannot see how to do two things with CrossWorks for the MSP430. 1. inline assembler; I have tried the usual asm("nop") but to no avail 2. interrupt functions; again I cannot seem to be able to get this to work ~ the documentation actually has an example for the ARM! (the syntax is different, it dosen't work) I am sure there must be some way of do

I am new to the MSP430 and the MSP430 way to do things. So if I am doing something stupid let me know. I designed a board with a MSP430F1610. It has a 32,768 Hz clock on the first clock port used for the ACLK, and a 3.6864 MHz clock for the two UARTs (SMCLK). The processor instructions will run off of the DCO. (That is the plan at the moment.) I have a function written in assembler, th...

I was just asked by a local college prof about the idea of modifying his CS162 course (a winter term, coming up) to use the MSP430 processor. His students need to write a simple assembler tool of their own, as one of two class projects they must do, and it needs to generate binary code that can be simulated. (The second project is, in fact, the simulator.) He is thinking about the idea of ...

Hello Folks, In a metering application report there was a mention of several CAD tools from TI: LWDF_DESIGN: Design of Lattice-WDFs LWDF_COMP: Transform of these designs into assembler Supposedly there is also a program that allows fast transient simulations on a model of the MSP430, called DSP430. I looked up and down the web but nothing. Tried the TI knowledge base but that has neve

I have an application where I have tight assembler loops polling Timer A and wiggling pins. I would like to combine this with running Timer B in interrupt mode to provide a "if it's not done by now it never will be" exit path for the code. I'm not worried about the interrupt changing the Timer A loop timing, because it will be terminating it anyway (e.g. if I get an interrupt at all, it's...

Hi, today i tried to migrate an existing MSP430 project with mixed C and assembler from IAR 1.26B to 3.10, because i need support for the MSP430F1611. With the old IDE i could override the __low_level_init contained in the cstartup code by declaring my own. This was the recommended method. It doesn't work any more. My __low_level_init is in the link map, but the cstartup code lacks t

Hi! I need IAR guru's advice! I have a very structured C program and I set the proyect ing high optimization. In many places I call functions that are only call in one place so I wait the Compiler to Inline those functions to avoid the call and then assembler lines. How can I do that !?!

Hello, I develop one university project with MSP430F148 microcontroller. And I must call one Interrupt Service Routine with the period of 16 us. I read in the manual that the one instruction take 1 cycle (=125ns on the 8MHz) and all instructions take the same time for run. In my ISR are about 60 assembler instructions and this ISR take about 13 us (13us/125ns = 104 instructions).And now i

Hello All. I am working on a project that incorporates both C and Assembly functions in several modules. I have followed through with the requirments stated in the IAR manuals and the TI document (SLAA140) concerning the correct usage. My problem is, that when I want to use these Assembly functions as part of the modules in my "Main" module, I receive the warning that the function is ...

Dear members ! In a C code, how to write assembly routine for multiplication?. i.e. how to multiply 2 C variables with the help of assembly instructions for F149 micro?. (it has the hardware multiplier). I am using the IAR Embedded Workbench v2.10A. Are there any special settings for the Assembler?. Regards KHubaib

Hi, I'm trying to uncluter my programs using macros. This works well if I only call a macro once, but doing it twice generates a "Dupilicate Label Error". According to an MSP430 Family Assembler Manual, the solution is to place a ? at the end of each label, but it doesn't work in my setup. I have the macro code in a file (MAC_Test.s43) and the code is: Test

Hi all, I make first attempts to work with FG4616, moving assembler code from F449. Linker gives me 1 warning: Warning[w29]: Parts of segment DATA16_N are initialized (as in module Mymain), even though it is of type DATA (and thus not promable) I think this is due 'holes' between byte and word aligned zones. When i invoke debugger - debugger finds target (TI-FET ,LPT) , downloads but s...

I am translating a few dozen lines of c code to msp430 assembler (so I am doing this manually rather than trying to integrate a small amount of inline C to what is otherwise an assembly language program). I have several places where two 16-bit signed integers are being compared arithmetically. Either number may be negative, zero or positive, but is not known prior to assembly time (for examp...

I'd like to develop a macro in IAR assembly which switches to a different relocatable segment by "pushing" the current one, switching to a specific named segment, assembling some code or data, and then returning to the 'current' one, without knowing it's name. The macro should be usable from any module and segment type, including absolute I suppose, and should be able to change th
