We’ll learn about Vim, Make, Adding, Subtracting and converting Decimals, Binaries and Hexadecimal numbers. As per Assembly Language we’ll learn about Registers, the Current Program Status Register, Receiving Input, Outputting Data to the Monitor, .global, MOV, SWI, ADD, SUB, MUL, MLA, Syscall, LDR, .text, .data, CMP, Branching and a whole lot more.

    At the very end, how is r1_lt executed? Is it because the program goes into neither BEQ nor BGT and thus by default goes to r1_lt like an ‘else’ statement?

    19:50 Hey Dr Bananas (Dr is shortened version of Derek 🙂 ) love your vids, and been a sub for years. I used to know binary but not well… but now I’m confused with 0111 + 1011 ..

    1 and 1 = 0 carry the 1. O.K.
    1 and 1 = 0 + carried 1 = 1. O.K. BUT why is there a 1 carried over here now when it’s actually 1 + 0?

    I thought a 1 is only carried over when it’s 1 + 1… I’m guessing since there’s originally a 1 and 1 prior to there being a carried over 1.. That even though it equals 0 + 1.. that a 1 gets carried over regardless even though the actual addition problem breaks down to 0(1+1) + 1.

    22:39 I thought ‘$’ signified a value to be stored instead of ‘#’… Or is that just for x64 Assembly?

    24:18 so setting the register to #3 means accept keyboard input? Could you have used R0, or R2 instead of R7? Do each of these registers serve specific roles? Like one is default for keyboard input and another with mouse input? So #0 represents the keyboard, and #3 means keyboard input mode in other words?

    Confusing. #3 signifies a mode, #0 is an object of input, but then #10 is very different than both of these signifying a size. So does this mean R2 register is always used for setting sizes of the objects in R0?

    So I’m probably wrong about this but R7 register sets the type of input modes, R0 sets the input object, and R2 sets the size of the input object or does it just set the size of whatever register comes before it?

    Or are these registers arbitrary picked which can be swapped with each other serving no specific purpose, and That the order they are in is what is important?

    32:34 so _start could be written as start? _start and other aren’t part of the language but are used defined variables?? Or labels as you called them??? This just keeps getting harder to understand. How does Assembly even know what start means? Or does it not mean anything and just something we use to help identify the code? I’m guessing we don’t need a "start" or "other" since they aren’t keywords, nor do we even need to use these labels am I right? Or are these labels being used because you are going use a branch?

    Im getting confused when you use Registers. For example, at 27:30 you simply changed R7 to R1. Why was that? Also, are you just assigning values to random registers to start off? or is there a reason why you chose those registers?

    The difference between architectures isn’t in mnemonics only. On CISC you can use memory addresses directly almost anywhere, on RISC – only in load/store instructions.

    This is great. But I’m not sure if I would have included a crash course in VIM. I grok VIM pretty well and cherish it, but it’s easy to forget how frightening it is to people who have never worked with it once you’ve got the editing and movement commands committed to muscle memory. I think it derails the focus a bit. Any "normal" non modal text editor would have done as well, as would have just not mentioning VIM while working with it.

    Just, like, my opinion though. Thanks for the ASM intro!

    Also, and sorry for the multi question:
    is this tutorial compatible for the raspberry pie 3 b+ ? it has an instruction set – ARM v8-A, which is 32 bit, but soon all will be 64 bit, will everything change then ? Thanks!

    i really don’t understand because you are not start step by step you think that the followers are professionals please start from how to install and access the assembler

    If you want to teach assembly you shouldn’t also teach vim and make. Just use any simple editor that people don’t have to learn. Make is actually fine because it’s really simple but vim is really complex for a beginner.

    from the command line, do you install vim and make directories on the rasperry pie itself ? does it have a flash/hard drive ?
