Very basic tutorial. Getting started with a step by step tour through the hello.c program that loads when you first start SimpleIDE.

There's a very simple, very brief overview of the memory models at the end.

Feedback is appreciated!! Thanks!

Enjoy!

    Much different than the toggle tutorials?

    Maybe, maybe not. Some things soak in differently for different folks.

    Thanks for taking the time to read it.

    I thought it was good.

    Only confusing part is the part where it talks about sleep running slower than waitcnt due to it not fitting within the cog. Makes it sound like the code executes slower - but it's comparing clkfreq/10 to sleep(1).

    Thank you, I should change that so it is apples and apples on the delay times - it just looked kind of strange with usleep(100000) in there.

    Why not change it to waitcnt(clkfreq+cnt)?

    I was trying not to introduce a change to the demo code in the distribution but it coul certainly be done as part of the tutorial. A chance to explain CLKFREQ and CNT - good idea!

    Such fluid, clear, and friendly writing! My writing is like a tar pit by comparison.

    Thanks Rick.
