Sub-par ad9833 sweep using arduino.

Okay. I know we have to USE software, it’s an occupational hazard, but the continual “evolution” of it, coupled with the egos and personal interpretations of software - ahem - “engineers” - makes it a time sink and one which drags me down a rabbit hole, the likes of software and bytes and utter piffle, the likes of which I’d rather not have to go down, were the entire internet not so overly enamoured with computers and an endless array of digital modules that take the long way round the houses, only to reinvent the wheel of what could be achieved with discrete components (were people not so lazy - me included).
Rant over… almost… I digress. This link tells me how to create a sweep generator; I’ve done so, and it’s trivial - it’s built. What I can work out (this whole rant is likely my misunderstanding the utter bollocks that is arduino, and the inability of “makers” (ugh!!!) to document things in a thorough fashion)
Why does this “sweep generator” not generate a continuously increasing or decreasing frequency output? Instead, it JUMPS to the next increment or decrement.
I’ve no desire AT ALL to delve into the nonsense that is arduino, nor the bollocks that is the code that powers it all.
Could someone, if possible, please tell me why this code jumps, and doesn’t generate a smooth linear sweep?
Thanks. Ranting through misunderstanding, possibly, and the anticipation of people coming along here and telling me how stupid I am to not be able to mentally cope with taking all this in, merely to achieve a simple freq sweeper.
Ps: this is what springs to my mind when I think of “makers” and arduino users in a general sense; this person's worded it spot on:

So, you took someone else work, because you are not capable of doing the same yourself, it did not do EXACTLY what you wanted, but again, you are not knowledgeable enough to fix it, yet you are shitting on the author that could make things work? Sure, Arduino is the problem here.
And instead of linking to the project you failed to use, you have linked to some other misguided rant about Arduino.
You are the problem here, not Ardiuno or its users.
If you think all Arduino code is bad, then simply don't use it. Just forget it exists. You need to understand that nobody owes anything to you, not delivering working code, nor documenting it. You've got it for free, you have no standing to dictate what the author should or should not have done.

Oh there you are! You pop up like a mole 😁 don’t make me waste the mods valuable time by reporting you for provocation. You have a track record of jumping into my threads, adding nothing but antagonist smart guy replies. I’m not reporting this for respect for the mod’s time, but if you’d kindly go away, it would save me getting out the fly spray.
Happy Old New year. Спокойной ночи

You are an old bitter man. All you do is rant and complain.

Rise above it. Be the better person and walk away then, set a standard. Are you being held at gunpoint, against your will? Nope.
