adafruit-motor-shield-library's Issues

Global constructors will setup timers too early

if you create a global timer object (AF_DCMotor foo(1, MOTOR12_64KHZ)) the timer registers will be set up during the global constructor phase of sketch startup, which is BEFORE the Arduino core library comes along an initializes the timer registers as it needs for analogWrite() purposes. As a result, PWM frequencies will be wrong.

THe library is not working with esp8266. Please make it compatiable with ESP8266. Thanks

Thank you for opening an issue on an Adafruit Arduino library repository. To
improve the speed of resolution please review the following guidelines and
common troubleshooting steps below before creating the issue:

• Do not use GitHub issues for troubleshooting projects and issues. Instead use
  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
  something isn't working as expected. In many cases the problem is a common issue
  that you will more quickly receive help from the forum community. GitHub issues
  are meant for known defects in the code. If you don't know if there is a defect
  in the code then start with troubleshooting on the forum first.

• If following a tutorial or guide be sure you didn't miss a step. Carefully
  check all of the steps and commands to run have been followed. Consult the
  forum if you're unsure or have questions about steps in a guide/tutorial.

• For Arduino projects check these very common issues to ensure they don't apply:

  • For uploading sketches or communicating with the board make sure you're using
    a USB data cable and not a USB charge-only cable. It is sometimes
    very hard to tell the difference between a data and charge cable! Try using the
    cable with other devices or swapping to another cable to confirm it is not
    the problem.

  • Be sure you are supplying adequate power to the board. Check the specs of
    your board and plug in an external power supply. In many cases just
    plugging a board into your computer is not enough to power it and other
    peripherals.

  • Double check all soldering joints and connections. Flakey connections
    cause many mysterious problems. See the guide to excellent soldering for examples of good solder joints.

  • Ensure you are using an official Arduino or Adafruit board. We can't
    guarantee a clone board will have the same functionality and work as expected
    with this code and don't support them.

If you're sure this issue is a defect in the code and checked the steps above
please fill in the following fields to provide enough troubleshooting information.

Convert examples from .pde to .ino

Hello! Here is the Arduino Create team.
Examples from this libraries are still in .pde format.
On the Arduino Web Editor all the .pde sketches are converted to .ino the first time you save, but since this is a read-only example it is saved as a copy in your Sketchbook. A bit inconvenient.
Here the report from a user.

Since .pde files are quite obsolete now, would it be possible to update the examples format from .pde to .ino and make a new tag of the library?

Thanks a lot!

Add support for PIC32 architecture (chipKIT/MPIDE)

It sure would be neat if this shield worked for chipKIT boards too.

AFMotor won't Compile on My iMac OR Windows PC

I have down loaded the AFMotor files and added them to my Arduino IDE but they won't run on either machine, both come up with the same error reports, did anyone have this problem and If so how did you overcome it. This is the error that comes up for the motor test sketch.

This is way out of my league so if someone can assist I would be very much appreciative of the support.

onestep() optimization

onestep() is the innermost call most people will make when running their steppers. As such it should be as efficient as possible.

One way to optimize it is to calculate values in advance and store them for when needed. At the start of the onestep() method the values a, b, c, and d are recalculated for each stepper, though they remain constant for each stepper. I made private class variables calculated in the constructor, turning 4 assignments, 4 shifts, and a branch into 4 lookups.

As a bonus the release() method can use a, b, c, and d in the same way.

If this optimization makes it into the next version, please give a little hello on your blog to http://marginallyclever.com.

Error: no member named 'setMinPulseWidth'

I've used this sketch in previous versions and it's worked fine. When I installed the new IDE though, it won't work.

polargraph_server_84.cpp: In function 'void setup()':
polargraph_server_84.pde:-1: error: 'class AccelStepper' has no member named 'setMinPulseWidth'
polargraph_server_84.pde:-1: error: 'class AccelStepper' has no member named 'setMinPulseWidth'

I'm not sure what I'm doing wrong, I haven't changed the sketch.

Thanks!

Double Precision Floating point

Dear all,
I am using below version of MPIDE, I am trying to NREL code on chipkit UNO32 Board. Nrel CODE on above board. SInce the algorithm involve Double pres ion floating point.I have attached output expected and the result coming out from MPIDE ide.i run same code on mplab with c32 compiler Where i am getting as expected when run on visual studio. But result are totally different when run on controller and also process is getting slowing down.
Question are"

1)Which version of IDE similar to arduino Work better here with double precision floating point

Error: "AF_Stepper" does not name a type

Got this error when attempting to verify "AFMotor_ConstantSpeed" example file. Is this a compatibility issue with Arduino 1.0-rc2?
