Is it possible to put the A4988 to sleep from the program? There is a sleep mode pin on the A4988 module, but it seems that the reset/sleep pin were both grounded (off) according to the schematic diagram.

Hi, A4988 requires 8~35V power supply. we recommend careful reading of the A4988 datasheet for the detail before using this product. http://www.dfrobot.com/imag...

What is about the wiki code? Does it work?

You can use all digital pinson the shield.Because DF already remove D4,D5,D6,D7 which are recommended in this shield.

Looking at the schematic, the two stepper drivers have step and direction signals only. they connect directly to arduino pins: PWM2, PWM3, D4, and D7. Enable for each driver is tied to ground. From what I can tell, you should be able to use the Arduino stepper library.

Sorry.my mistake.All "M1steppin" to high level .Because it use digital pin to control the motor‘s direction and speed。 .the Most simple Way to stop the motor is stop the change of steppin

It could control the motor action, rotating and stopping. just the sleep function has been forbidden.

Hi, it doesn't need any library, you can check our wiki page.
