stepper.h

I realise its a fairly simply control library, But ive noticed it doesnt seem to fully work under STM.

Running the same code in STM i get very very slow stepper move loops…
Anyone know whats causing it and how to make it go fast again?

where is this file?

Hmm its in the core library of arduino… Tbh dont worry about it. The library works… Just for some reason its very slow on the stm. Its just a set of bit read outs and if statements. It shouldn’t be this slow and tbh shouldn’t need porting.

Sorry

I think the problem is in line 177 of stepper.cpp
this->step_delay = 60L * 1000L * 1000L / this->number_of_steps / whatSpeed;

I would give the acc stepper library a try:

trying to run the accel stepper lib but getting an error

Did you upgraded your IDE recently ?
Becuase it seems that you lost the toolchain path, and/or it can not read the plateform.txt file properly

Hmmm nope but I have been tidying up the library folder as i was trying all sorts and some conflicted…

Its possible i might have moved that file. Though its not there now. Im trying to find the download to put it back

found it, it in the hardware folder… looking inside the file it seems complete… no corrupted text, complete code. If there anything I can do to fix the links?

Fast again? You mean it was working faster before or do you mean fast as compared to an Arduino?

I upgraded to STM32 partially because Arduino stepping is too slow. I hope it will be much faster though I’m also considering using hardware timers for pulses. Haven’t found a lot of info in that.

I wrote the Accelstepper code last night and hope to test it tonite I’ll let you know if I run across something related to your error but that sounds like a general tool chain issue than anything related to the library.

I’m a noob at stm32duino but if it were me I’d try reinstalling stm32duino. Maybe that’ll restore the tool path. Which ide are you using?

WOW, year old thread reborn :p

Im way past from this issue. So much so ive completely forgot what it was :p

Im using x27 motor gauge steppers now… Manually driving them from a arduino mini.

And theyre fine. A little noisy but fine. Seem to get enough current from the arduino pins directly.

Im also using a tweaked version of the x27 stepper library… I tweaked it…
Cant remember what i did though :p

As for IDE i use eclipse now. But still using arduino for building. Eclipse doesnt always seem to correctly build some libraries for some reason, must be something missing in the sloeber toolchain.

Roger, I need to control one stepper motor. I am looking at the Accelstepper lib. I see it says max speed for Arduino is 4,000/sec.
Is the speed of the STM32F103 just the ratio of the crystals*4,000?
Arduino 16mhz = 4,000/sec. 72mhz/16mhz = 4.5.

4.5* 4,000 = 18,000/sec.
is this correct?

I do not know the library you are using, but in Marlin I can run steppers at over 40Khz with interrupts in the F1, and that’s while doing several other things at the same time, so you should be able to achieve those 18000 steps/s easily.
