Steppers not supported?

[rubenmp8]

I am trying to create a stepper control on an Edison board by doing the following taken from the johnny-five docs

stepper = new five.Stepper({ type: five.Stepper.TYPE.DRIVER, stepsPerRev: 200, pins: { step: 11, dir: 13 } });

However I am getting a Stepper is not supported error

Error: Stepper is not supported at new Stepper (/home/rmperez/test/node_modules/johnny-five/lib/stepper.js:128:11) at initializeStepper (/home/rmperez/test/app/controllers/mcu.js:28:13) at Board.exports.gotoPosition (/home/rmperez/test/app/controllers/mcu.js:41:3)

I made sure to upload a sketch using AdvancedFirmata before this. Are steppers not supported in galileo-io or am I doing something incorrectly? Thanks

Thanks for the report, unfortunately...

This is correct. The docs also include this notice:

In order to use the Stepper class, your board must be flashed with AdvancedFirmata, which is available here: https://github.com/soundanalogous/AdvancedFirmata

(And the platform page: http://johnny-five.io/platform-support/#intel-edison-arduino)

I apologize for this being unclear, and I have updated that to be more specific:

Currently, Stepper is only supported when using Johnny-Five with an Arduino (tethered via serial usb). In order to use the Stepper class, your board must be flashed with AdvancedFirmata, which is available here: https://github.com/soundanalogous/AdvancedFirmata

Please note that this is only temporary. Updates to follow

Also, you'll want to remove that sketch from the system:

rm /sketch/sketch.elf 

[rwaldron]

As it turns out, if you're using the SparkFun Arduino Block, you can flash Advanced Firmata to the Arduino and run JS scripts from the Edison. https://github.com/rwaldron/galileo-io#sparkfun-edison-arduino-block

Cool, I have the arduino breakout board, but I'll look into using the Sparkfun block as a temporary workaround.

Out of curiosity, what are the issues blocking Stepper support on edison+arduino breakout board?

None, I just haven't finished writing support yet :)

I worked on it all day today, should be ready for testing tomorrow-ish.

Awesome, thanks a bunch for working on this immediately!

[rwaldron]

Sometimes I just need a little outside motivation ;)

Appreciate you bringing this bug :)

[rwaldron]

Update:

• Stepper support is nearly there
• Speed is a problem and has been the cause of delays

[rwaldron]

No matter what I try, I cannot get the speed to increase beyond a certain point.

Ouch, how slow are we talking?
