Suggestion: Since there are many lessons, you should attack another zip file in the first post that contains every single lesson in one file, so newer members won't need to download each lessons one by one

Hmmm...well, I'm certainly going to do that when all the lessons are done, but maybe I should think about doing that for every new lesson I do.  After all, I need some kind of excuse to do lesson 1 / lesson 2 htmls and docs

Lesson 12.

We're making S.A.D. easy to program, and not easy to modify.  However, we are releasing the source code under GPL.  Reminding everyone that the idea of S.A.D. is using a single unit with a single purpose, do you have a version of S.A.D. you would make if you could? 

For me, I would create either a Star Trek S.A.D. or a Starcraft S.A.D. if I had the chance.

* Some mysterious person on Omnimaga bonks Hot Dog on the head*

Universe: Ragnor

Star System: Runia
Population: Average of 300,000 Tosonians
Diameter: 11,000 km
Dominant Terrain: Barren Rock
Geography: One Continent, several islands surrounded by lava
Orbital Period: 25 Earth Days
Rotation Period: 12 Earth Hours
Additional Characteristics: Bronat's Moon


After researching the creatures that had been destroyed with the elimination of Carbon Bol, the Tosonians discovered just what it was that made them resilient to heat.  As Tosonians are able to take on different forms for the purpose of adaption, they were able to add these characteristics to their human form, enabling them to leave and enter the moon Ragnor whenever they desired.  Ragnor, being rich in belthium crystals, gave the Tosonians an upper hand in the Tosonian War until the invention of the Scouter.

Numerous assaults on Ragnor have all ended in failures.  Vessels can last only 15 minutes on Ragnor once through the atmosphere, and surface defenses prevent quick/direct assults on structures themselves.  This meant assults either exceeded the 15 minute time limit and plunged to the surface from overheating, or they had to leave early to prevent the deaths of hundereds of pilots.  No attack has been made since 270 AL.

The power generators that could potientally run the buildings on Ragnor require lighter armor and thus cannot last on the surface of the planet.  However, all the structures on Ragnor clearly run efficiently, which means they have some source of power.  No human or Ptaloid knows just what that power source is.

Lesson 11 is up.

What's the terms of redistribution?

For larger tasks like a tile mapper, you can let your tile mapper work during the delay. You actually gain speed by not wasting time in doing nothing between writes. (Note that normally a good tile mapper like dwedit's, jim_e's or calcmaniac84's copy the old screen to lcd and compute the new screen that will be copied in the next frame.)

How do you do something during the delay?  Is it natural, or does it involve interrupts or another process

We control when the LCD updates by copying plotsscreen to the lcd ram when we need

Oh yeah, I forgot that one could copy just part of plotsscreen.

Thx Buckeye and everyone!
