you're controlling a motor and can yield to the scheduler? does anything bad happen if someone else takes a long time and you miss pulling the pin back low until, say, 5ms? 20ms?

No, other than the motor not moving

JawnV6 posted:

you're on some kind of m4f, right? ~100mhz? you can approximate how many instructions before you'd have to preempt a task if you just want to get close

Cortex m0/samd21g18a/arduino mkrzero so 48mhz I think. Maybe with a 1ms delay I might as well just block

ahh, alright. i'm more familiar with h-bridges and other control schemes where leaving current dumping into the thing would be Bad

if it's just stepping on an edge trigger that's nifty

48,000 instructions you can get a lot done :v:

i dunno, imagine your task switching takes 4k (unlikely) you've still got 40k instructions to mess around with

Yeah it's one of these: https://www.sparkfun.com/products/12779 which is rising edge triggered.

zooming out to the 'product' level if you've got the stepper assembly together, you could artificially introduce jitter and see if it's perceptible

like set up a list of 1,5,1,1,1,1,15,1,20, etc. and delay by that much. i think you'd perceive some judder pretty easily, but maybe the steps are so small and 20ms is 'fast enough'

an alternative to blocking calls would be writing a timer ISR to handle it, something like

code:

void timer_isr(void)
{
  if (moving) {
    if (state) {
      self.step.pin_high();
      state = false;
    } else {
      self.step.pin_low();
      state = true;
    }
  }
}

when you wanted to move, set 'moving' true and enable the ISR, or you could decrement a counter and have it turn itself off [fixed]if (count > target) { moving = false; disable_isr(); }[fixed]

CRIP EATIN BREAD posted:

Here's the thing: I did write a tool to generate database XML fixtures instead of writing it by hand.
So the idea was to go to staging, say we want table A, rows X, then the tool would dump that, and then you would repeat for dependency table B, dependency table C, D etc.
All my tests to generate XML files for tests ended up being almost full dumps of the entire database structure. It was at this point I learnt that the database was a piece of highly dependent hell. The reason why developers started hand writing XML files was so that they could cheat and leave out references to reduce the XML file requirements, even though this basically resulted in a test where the database would be set up into an invalid state. Bad design is one of the things that you can't go back and fix with tools.
At this point I resigned myself to bloodshed.

well, it's true.

i had a phone screen tonight for an MIT-based startup being run by basically children. they had no idea what they were doing but their product is completely insane and i love it.

it's "task based" and way underpays but it requires literally no investment on my part so imna go for it because i have no responsibilities or concerns and it sounds fun and i might get paid and i'll get to put rust on my resume.

if i feel exploited i'll just stop.

yeah i'd like to see this thread rebooted with some mention of the rules. i'm also not really sure what the rules are anymore. personally, I want to see:

this thread is the programming thread

the other thread is also the programming thread

this one tends to have more beginner questions and shitposting and day to day

the other one tends to have a bit more effort posts but also a bit more telling people to go gently caress themselves

i guess this is the thread people post in because they don't think they're smart enough to post in the other thread
