Adjust microstepping on BED from Arduino?

Hi,

This might be a really simple / stupid question:

On the BED, there is three terminals (M1, M2 and M3) which decides the microstep settings. They have internal pullups (20K). To change microstep setting, I tie one or more to ground depending on what setup I want.

If I dont connect them to ground, but to the Arduino's digital pin (output), would it be possible to adjust microstep settings by setting the digital output either HIGH or LOW?

Yes. That is how it is meant to work.

BED?

MarkT: BED?

BigEasyDriver.

Or a place to sleep.

Never seen that abbrev. before! Is the EasyDriver “ED” then?
