SpeedyStepper VS TMCStepper

Library: https://github.com/Stan-Reifel/SpeedyStepper https://github.com/Stan-Reifel/FlexyStepper

I have not created schematics yet, I simply followed the specs of each boards and connected them and programmed. I will create schematics soon and share. For stepper control and connections, I used SpeedyStepper library examples here: https://github.com/Stan-Reifel/SpeedyStepper/tree/master/examples

You don't necessarily need a single shield to control them all is recommend using small, individual driver boards all mounted on breadboards honing up directly to your Arduino. Fundamentally, most stepper drivers use a 'step' and 'direction' pin, do every time you pulse the 'step' pin the driver turns the motor one position, and if the direction is high or low changes the direction the motor turns. Is suggest using a library like https://github.com/Stan-Reifel/SpeedyStepper it's very popular, way to use and there are lots of good examples. Start with getting one motor controlled how you like, then look at their examples for using multiple motors and build it up. For motor drives, you have two fundamental options: Breakout board style: https://www.pololu.com/category/120/stepper-motor-drivers these are the type that mount in most 3d printers, and are fairly compact l, but need some wiring work done to be correct. The other type is a fully enclosed type: https://www.amazon.com/Digital-Microstep-Stepper-Controller-2-phase/dp/B07YWZRXGR these are controlled in the same way but can draw much larger currents and are probably easier to wire and set up. United space is critical for you I'd recommend these. Both types are controlled with the same step direction method. I hope this helps, let me know if you have any questions

Now take a look at the header file of the library TMCStepper you want to use, https://github.com/teemuatlut/TMCStepper/blob/master/src/TMCStepper.h

(...) /** * Beta feature! * Create a 50/50 square wave step pulse optimal for stepper drivers. */ //#define SQUARE_WAVE_STEPPING /** * Enable M122 debugging command for TMC stepper drivers. * M122 S0/1 will enable continuous reporting. */ //#define TMC_DEBUG /** * You can set your own advanced settings by filling in predefined functions. * A list of available functions can be found on the library github page * https://github.com/teemuatlut/TMCStepper * * Example: * #define TMC_ADV() { \ * stepperX.diag0_otpw(1); \ * stepperY.intpol(0); \ * } */ #define TMC_ADV() { } Any thoughts?

My problem is that the library I'm using for the TMC2208 is made for the AVR architecture which means the ESP8266 seems to be incompatible with the code. I belive I have a few options.

The library is called TMCStepper, and this issue suggests softwareserial cannot be used. I have tested it myself and can confirm this. Solution would be to get an ESP32 that has multiple hardware serial connections.

I looked into the code and it turns out that TMCstepper makes use of basically 2 functions to write to the register (here lines 187 and 281), so should the example given above not work you have a second option !
