[Mspgcc-users] Examples

[Steve Underwood]

Hi all,

The mspgcc examples hasn't seen a lot of activity lately. I thought it 
was time to change that. :-) I have adapted all the TI packages of 
MSP430 example code to work with mspgcc.

For the C examples, only minor changes were needed. The syntax of the 
interrupt routine definitions was changed to the mspgcc form. The main 
routines were changed from "void main(void)" to "int main(void)".

The assembly language examples needed greater changes. The binutils 
assembler supports the same basic syntax as the TI assembler. However, 
much of the control syntax is different - DW => .word; ORG => .org and 
has a slightly different meaning; hex numbers need to be in the form 
0x1234; a number with a leading "0" is octal; etc.

I changed both the C and assembly language examples to include <io.h>, 
instead of specific header files for particular devices - its the mspgcc 
way :-)

The modified files is now in the mspgcc CVS, along with make files to 
build them (the original packages did not include make files). They all 
compile cleanly, but I lack the hardware to test many of them.

I have also been looking through the existing examples in CVS. I changed 
the TCP/IP example to build nicely with a make file. Previously there 
was no make file, and one .c file included all the other .c files - 
messy! The tasker and bufferedUSART examples had make files for MS 
nmake. I changed them to build with GNU make, so they now work under 
Windows and Linux/BSD/Unix of the month.

I aim to start adding some useful routines I have written. Some of this 
stuff should probably form a library. However some will often need 
tweaking for a particular use.

Regards,
Steve
