What I mean by a software emulator is, an application that runs on a desktop/laptop where some favor of MSP430 code can be run and tested, as if it was running on the actual chip. Hope that makes sence.

You're asking about a software simulator. I've only used the one provided by IAR - but it is impressive. It's configurable and you can program IRQ's - etc. I think the simulator may work in the free 8KB version - you can go to www.iar.com and take a look.

I don't want to start a religious war, but could a few knowledgeable people give me their impressions of the relative advantages of PIC vs AVR? Assume that I will be using both, to some extent, for some time, and want to know what their relative advantages are. Throw in MSP430 too if you'd like. I'm mostly using PICs right now but am stuck on the fact that MPLAB requires you to have w...

I've been planning on using a MSP430 for all my very low powered control work for a while, and was about to order the dev kit ($99, cant argue with taht). Eventually I'd like to get TinyOS running, hopefully to simplify some of my own work, and I noticed that 2 of the 3 reference platforms are ATmega128 platforms. I'm pretty sure the MSP430 cant be beat for power consumption, but i really...

Anybody know which MSP430 programmers work well with Linux? I was thinking of getting the ez430, which is almost free, but I read in an earler thread here that the USB interface was proprietary and Windows XP only. Nobody's paying me for this one, so it has to be fun, and that means not dragging out the Windows box. :) I'd rather pay more in dollars upfront for some hardware that works tha...

I have this love-hate relationship with TI's documentation. On one hand, once you understand a module, you can use it on any micro. On the other hand, the cross-referenced docs are usually inconsistent and /always/ very confusing. (I still haven't worked out how to connect, let alone use, the sigma-delta ADC, and every time I try to use a timer on an MSP430 I wind up playing with clock contro...

A few weeks ago I posted a request asking for cheap (vs Olimex's MSP430 boards) EVBs with Ethernet to build a proof of concept and then use the design as the basis of a low-volume production run.

It is a long time since I looked at Rabbit, but I took a look, talked to their sal...

Hello Folks, Looks like I'll have to debug code for a small uC (MSP430) in the field pretty soon. Cramped space, things can be banged around a bit, the usual. What would be a small, low cost and bare minimum laptop to do that with? Or is there a nice PDA where a keyboard can connect to? The programmers work via USB. The bootloader I may have to provide would be RS232 but that could b...

Hi, I have an MSP430 and set the watchdog timer, however, when I cut power off and return power, sometimes it'll reset, and sometimes it won't. If I check with my debugger where it's getting stuck, it's just between two lines that say something like e30 BITB.B #4, 0X0028 e34 jnz 0Xe30 and it will loop forever there, however this will only happen part of the time, other times it'll work...
