ESP Blynk library blocking?

So, I’m guessing that using Blynk in stepper motor control and other similar applications is a no-go?

Not at all the case… Everything is possible, but it takes some tweaking and you may lose some degree of really fast Stepper control.

C++ Blynk (Legacy) - Code Examples for Basic Tasks

#23 - Basic Stepper Motor Control Who says Blynk can’t control Stepper motors… well, OK, I have said it may require fancy non-blocking timing… so here it is (disclaimer, not all that fancy after all ) Yes, it is using the old and decrepit Stepper.h library… only because I was too lazy to learn simple accelStepper commands at this moment I am also controlling a 4.29v 1.8deg NEMA 17 stepper with an equally old L298D motor controller… Hey, I works with what…

Or even dual MCU control… Blynk on an ESP (or Arduino I guess) for the UI and an Arduino or ESP for the Stepper code… this way the only other “timing” issue you have to share with the Stepper code is the cross MCU link via i2c or Serial.
