Error on Code? about big_easy_driver HOT 5 CLOSED

Are you trying to run one of the code examples? If so, which one? If not, can you post the code you're trying to run? Also include some more information about your setup - what microcontroller board are you using, etc.

from big_easy_driver.

This is the code I was trying to use. It is the basic big easy driver demo It was posted here and on the main Big Easy Driver Page on sparkfun https://learn.sparkfun.com/tutorials/big-easy-driver-hookup-guide/all . I am using an Arduino uno, an 8 wire stepper motor and the Big Easy Driver.

SparkFun Big Easy Driver Basic Demo
Toni Klopfenstein @ SparkFun Electronics
February 2015
https://github.com/sparkfun/Big_Easy_Driver
Simple demo sketch to demonstrate how 5 digital pins can drive a bipolar stepper motor,
using the Big Easy Driver (https://www.sparkfun.com/products/12859). Also shows the ability to change
microstep size, and direction of motor movement.
Development environment specifics:
Written in Arduino 1.6.0
This code is beerware; if you see me (or any other SparkFun employee) at the local, and you've found our code helpful, please buy us a round!
Distributed as-is; no warranty is given.
Example based off of demos by Brian Schmalz (designer of the Big Easy Driver).

Caroline - when you post to GitHub, it comes through email as well. You can reply to either - they all show up on GH.

When I copy/pasted the code you provided into Arduino 1.8.7 and built for Arduino uno, I didn't get any errors or warnings.

Can you copy/paste the output of your compile (make sure to turn on verbose output for compilation in the preferences dialog box for Arduino first)? Maybe there's a clue there.

from big_easy_driver.

Checking that box in the preferences allowed it to verify. Thank you!

Very good. I'm going to close this issue since the original issue appears to be solved. Please let us know if you have any other problems with the Big Easy Driver board.
