I just picked up a demo board from TI. Its been around awhile, but I can not seem to hunt sown the schematics. Its the round PCB with a MSP430FG439 processor and an LCD display. The silkscreen says: "MSP430 Watch and Altimeter". Does anyone know where to find the schematic for this board ? Thanks Donald

Hi all, I'm currently working in an application that requires the MCU to g into deep sleep (LPM4) and wake up and process data on UART receive, an then go back to LPM4. What is the right way to do this? I tried doing th following as TI's guide Rev. E. suggests, but this crashes the MCU. tried to debug the code but I just can't find where the problem is.

I am considering using ST7 part with USB on-board. I have not used ST7 before, but have worked with PIC, AVR & MSP430. * How good are the ST7 tools? It looks like Cosmic offers a 4K limited version of their C-compiler. Is the Cosmic compiler/IDE (IDEA) any good? * How are ST7 parts to use? Any bizarre or strange problems? Thanks you. HW.

I'm an experienced C/C++ programmer, but very new to Embedded programming. I've bought the TI Flash developers kits that include the IAR compiler. I have some existing msp430gcc code, but there are some differences - particularly in how interrupts are declared. The issues I need to resolve: 1) some of my interrupt routines are declared as "wakeup". It's unclear to me how to handle th...

Having an IDE to work with is great, but is IAR worth the bucks? 1 - will it save that much time? Including learning time - especially for someone used to IDEs like Visual Studio? 2 - are there opportunities with the MSP430 to earn back the cost of IAR? 3 - are there any good IDE front ends for mspgcc? (and the debugger) -- ---------------------------------------------------------------...

Hello everyone, I am facing the following situation: I have a microcontroller (e.g. Atmel ATmega 128 or TI MSP430) connected via SPI to a flash memory chip (e.g. Atmel AT45DB014B or ST M25P80). I'd very much like to enable a second microcontroller to access the flash memory. The central question in this regard is: Can I add this second microcontroller to the bus without changing the soft...

We are working on a small MSP430F149 project and are having a heap of grief getting the basic hardware going. We continually get inconsistent results when attempting to connect and download to the msp430. Initially the JTAG will not connect but this problem appeared to rectify itself. It then had trouble writing to memory at address 0x1100 - the start of the program flash. Reseating the ms...

Take pity - I'm a newbie at embedded programming I've got a prototype with a MSP430 on a header board. I'm using the IAR compiler and the TI "Flash Emulation Tool". In Debug, the C-Spy debugger downloads a binary file to the MSP430 chip. Compiler Release mode, however, builds a hex/Text file which C-Spy does not handle. How do I download the release program to the MSP430 chip? (or do...

The following compiles fine in Visual Studio and is something that I do often: int a = 0; int b = 0; int* ptrs[2]; ptrs[0] = &a; ptrs[1] = &b; This same code complains that "the size of an array must be greater than zero" in IAR. Anyone know what I should do? Is there a switch somewhere that I need to flip in the options? Is this "bad" code, seems fine and lega

I'm looking for a mid-capacity static RAM part that I can use with a TI MSP430 series MCU using a few interface lines and serial transfers. I am finding a few serial-interface static RAMs (such as the Philips part) but those I'm finding are very small capacity for my application - 256 bytes or less. I need something in the 2 to 8K byte range, but static RAMs in that range are parallel (addres...

Hello All, TI's web site is, for the most part, pretty good. However, I find their DSP section shallow and horrible. Lots of glitz and fluff, not nearly as much "meat" as on their MSP430 section.

We want to make a portable device for reading some text. It is made for ourselves, and as a practice of course. So we want get a low cost on hardware. Some one suggest that MSP430 should work fine, but i don't know whether it can afford the loads. It seems that lacking of support free os for MSP430 is another problem. Is there any better choice?Any help would be appreciated.
