Power Level / Torque / etc about drv8711 HOT 6 CLOSED

Okay so I have played around some more, and answered one of my own questions...

I did test Microstepping with values as 8, 16, 32... all the way to 256 - great, working a treat! Confims my question above: "so it looks like thats easy enough, should be 16 for 1/16th microstep, and maybe 256 for 1/256 microsteps?" to be true...

Torque is still my major question though

If I look through the datasheet I understand from

If a 0.1-Ω sense resistor is used, ISGAIN is set to 0 (gain of 5), and TORQUE is set to 255, the full-scale (100%) chopping current will be (2.75 V * 255) / (256 * 5 * 0.1 Ω) = 5.5 A

In the case of the Boost packs we have 0.05 Ω so to get 5.5A drive (Max rated) the ISGain should never be set to 5. It should be set to 10.

The Torque bit in this example is set to 255 (full scale).

This is the part of your library I can't figure out... How do I set Torque between 1 and 255?

I see you were still active on the Propellor forums over the weekend so I know at least you are still alive (:

I started populating your Wiki: https://github.com/MarkTillotson/DRV8711/wiki

I found stepper.power()? Is that what I was looking for?

from drv8711.

stepper.power(DRV8711_FULL); and stepper.power(DRV8711_HALF); ?

Sorry, v. busy ATM.

Torque: You've got the code, I can't remember, I'd just have to look at it too!

The FULL and HALF values select full and half power respectively - its all in the code.

The code is the documentation, adding a Wiki in my github without my approval means
either I have to check it for accuracy and spend time on it (that I do not have ATM), or I'll simply delete it.

If you can't read code, please don't document it with guesswork, that just lowers the quality
of the information that was there already.

(: Thanks dude, was just trying to help as I realised by the 4 day delay you must be busy - but nevermind, will take my help elsewhere (:

Documenting your project would have made it more useful to everyone, but oh well. Just delete the Repo if thats how you roll (;
