Certainly not, but he asked about C programming, not writing portable
C code or inserting AGP cards into the appropriate orifice. I'm
thinking Knuth or something from O'Reilly rather than ISO/IEC
9899:1999. This may be a matter of which learning method works better
for the person- not everyone learns best starting with BNF notation
descriptions of the grammar. I like to see lots of examples as well.

I reckon ol' Kernigan and Ritchie is the go. You know, that little white
book called 'Programming Ansi C' or something like that, the book that every
uni students uses. That is that little AU$100 book that is worth every cent,
especially if you borrow someone elses copy and never return it ;-)

**** You are looking for Watt Hours,that is Watts consumed multiplied by
Hours used.In your first case if you use the 100 Watt bulb for one hour
,your electricity meter will register the usage of 100 Watt Hours (or
point one Kilowatt Hours in metering terms).

In the second case you will have to allow for the efficiency of the
device that is converting the 240 Volts to 12 Volts.

Allow about 60% for a transformer fed lamp.


** Huh ? Since when are lamp transformers only 60 % efficient ??


More like 90 % for a 50VA tranny and even better for larger ones.


For switchmode power supplies associated with computers,allow about 50%
efficiency due to low power factor.
Click to expand...

** The "power factor" is not relevant - that depends on the current
waveform distortion.

The power consumpton of a SMPS is the output power plus any heat losses
in watts.

A typical SMPS has 85 % or more overall efficiency.

For general programming questions, independent of language,
consider comp.lang.fortran most of the posters there
are quite reasonable about material that is not "bulls-eye"
on topic but related. And some of them even know something
about C as well.

straight away, i'd like to inform you that MHz doesn't meen all that much,
its how the unit performs vs how much it costs you.

I personally like AMD for computing becuase they are more efficient at the
job. there was a whole argument about AMD being hotter to run than intel,
but that hasn't been the case in the last year and a half. both chips
generate 60 - 80 watts of heat.

you could pick us an asus motherboard -a7n266-m (i think) all in one board
with G-force 2 graphics for ~ $135, an AMD ATHLON 2000+ CPU for ~ $140 and
a stick of 256 MB PC 2700 (333MHZ) DDR Ram for $90 so for

$370, you have video, ram, cpu, heatsink (these are a new design that are
dead quiet) sound, network card, motherboard, 2 ide, 1 floppy, all
connectors, 6 USB capable. just add CASE ($45) HDD ($100) CD Rom ($45)
Floppy Drive ($20) and you have the whole box

Burner for $95, 17" monitor for $195, Keyboard, mouse, speakers $35 ,
Windows XP Home OEM $185

roughly $990 for a FULL System with plenty of horsies and if the 3D sucks a
bit down the track, install an AGP Card and thats it.

Seriously, AMD is the best way to go, i run 2 (XP2200 and Duron 750) and on
the XP 2200, there is nothing i can't do on it.

I'm trying to hook up an LCD to PORTD of a mega8. The micro seems to lock
up.
I used AVR studio to step the program through and the simulator stalled on
the
following:


lcd_init(16);

lcd_init uses R26 and R27. I viewed these registers in AVR studio and
initially
they were not 0x00.
R26=0x6b
R27=0x0x

Any ideas?

thanks.

An Athlon 1800+ will compare to the Intels 1.8Ghz and it runs at 1.53Ghz.
You should be able to pick one up for around $100.
As for the motherboard. An Asus A7V8X or something is reasonably priced
or a Gigabyte 7VA is also a good choice at around $100. If I was buying a
board, I'd get a Gigabyte 7VA.

alt.comp.lang.learn.c-c++ is a lot better for a beginner.
A lot friendlier and more tolerant.
I'd rate it as one of the better groups.
Covers both c and c++, so you need to say which you are using,
uually with [c] or [c++] in the tile of your post.

Thanks for that. Yes I overlooked the fact that default clock is the
internal RC osc & had to set the appropriate fuse.

Thankyou sooo much

Have you set your lock bits to use the right oscillator. Perhaps you
are using the internal RC oscillator instead of an external crystal?
Don't know how you do that in AVR Studio as I use Bascom itself to
programme the chips.

Also did you set up Bascom for the right oscillator frequency you are
using and the "Compiler --> Communications" for the right baud rate
for your serial port?
