Eh, it's just like C really. Just a little easier and dumbed down. I think it's a version of "BASIC".
You have all your basic operators and a 48 word language set to work from.
Then your registers and your i/o. You don't even have to go through chip initialization. Ancient microcomputers.
I just get lost in my subroutines bigtime. I've seen some people be a whizz at these things like you wouldn't believe. I know it's capable of doing what I need it to, I just have to figure out how to make it do it by wording it right.
I'd be stuck on the same things with an atmel chip right now. Just have to figure out how the chip wants me to word it.
I have two small bugs. The over-shift thing as stated above and upon the return lean in the lean routine one LED gets stuck before another fires. I should be able to work them out with enough tinkering.
