[Mspgcc-users] problem while installing GDB of MSPGCC4
Hello everyone, I'm installing MSPGCC4 through Cygwin on windows (command: perl buildgcc.pl). BinUtils, GCC and Libc have installed correctly so far. But then when it comes to GDB (command in the script: bash do-gdb.sh /cygdrive/c/mspgcc4/ 7.1 http://ftp.uni-kl.de; build gdb), and after Unpacking gdb... and a bunch of patching file ..., I get try184.c:1:20: error: curses.h: No such file or directory and then Note that you must have libcurses developer headers installed. Abort.. Now, I do have the package Libs (and a bunch of others) which contains some libncurses... files in my Cygwin installation. And I do have the file curses.h somewhere in my mspgcc4 directory. Should I install a specific package for Cygwin? Or should I copy curses.h to a specific directory? Thanks in advance.
Re: [Mspgcc-users] problem while installing GDB of MSPGCC4
Not a cygwin user, so I'm reaching here, but there may be a package libcurses-devel (or libncurses-devel) that you need in order to get the headers. This is generally the fix for this problem when it arises under Linux. Unless you're sure the curses.h you found matches the libncurses library, I do not recommend copying it into the gdb source area. You'll probably just find that there's another header that's missing too.

[Mspgcc-users] Multiplication using Horner's method
Hi,
I would like to use Horner's method for fast multiplication on MSP430f2234.
I found source files from:
http://focus.ti.com/general/docs/litabsmultiplefilelist.tsp?literatureNumber=slaa329
multiply_int.c:
/**
* MSP430FG439 Horner's method to perform efficient multiplication
*
* Description: This code performs a integer-integert multplication of numbers
*41 and 441 to give the result 18081. The main C file calls
*four multiplication functions. The first is a IAR CLIB function
*followed by a conventional multiply algorithm, Horner's method
*and Horner's method with CSD format.
*
* Note:This code assumes 32.768kHz XTAL on LFXT1 on the MSP430FG439

My question is what exactly asm mul_horner_int does? Why it has only one
argument - comment states that it is integer integer multiplication that
multiplies two numbers?

The binary representation of the number 441 is embedded in the code from left

441 = 110111001b
Something like the following pseudo-code:

if d == 1

else

Re: [Mspgcc-users] problem while installing GDB of MSPGCC4
Go to http://www.elprotronic.com and download FET-Pro430. The Lite (free) version has done everything I needed. Use msp430-objcopy to convert the elf output from mspgcc to Intel hex and program with FET-Pro430. You may need to name the file something.hex to get FET-Pro430 to recognize it. Best solution I found prior to mspdebug working under Linux. Peter On Thu, Sep 2, 2010 at 1:38 PM, Mark J.

Don't have Mac OS X, but mspdebug allows me to use the FETUIF-430 under Fedora 13 on Linux. Infinitely nicer than an ssh terminal under Windows and a shared disk drive.

I hope that someday I'll be able to use the TI USB programmers under Mac OS
X, without needing to pop up WinXP on a virtual machine. Has anybody looked

fully open-source implementation that supports them can be created?
A fully open-source implementation exists, it's called mspdebug
(http://mspdebug.sourceforge.net/). And the protocol is not a USB one, it's a
serial protocol over a USB-to-serial chip (the TI3410). So, all you need is a
driver for the TI3410 for your OS, and you're done.

Re: [Mspgcc-users] problem while installing GDB of MSPGCC4
I'll look at mspdebug today. I was under the impression that the USB-based TI programmers (including the eZ430 dongles) were only supported under Windows (using TI DLLs) and Linux (using pre-compiled libraries based on proprietary TI code). -- Mark J.
