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:
