What does "non working" mean? Does it not compile? Does the upload fail? Or does it not behave as expected.
You will have to provide details like code (and libraries used if any) and wiring diagram for anybody to be able to assist (I might not be the one that can assist)
I've moved your topic to a more suitable location on the forum.
Isn't that the same as this topic:
Why opening a new one?
Hi sterretjeThe the library examplesof library TMC2209 , also TMCStepper were compiling (only some of them) but that doesn't moves my motor.
I used library TMC2209 , also TMCStepper library examples. But one of them are able to move motor.
Motor is ok as i tried that with A4988 driver. Drivers also i bought new to get confirmation of defectiveness in driver board. Connections are properly done too according to me. Microcontroller is also file , as it driven motor with A4988.
What is possible reason..... Did any example of TMC2209 , also TMCStepper library worked for anyone....Can anyone tell me???
Hi MicroBahner
I was not intended to do that , but i was not getting enough responses there which can provide me solution. That's why i opened new.
Hi, @pssingh
Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.
Lets start with how you have the 2209 connected to the ESP32.
Can you also post some images of your project?
So we can see your component layout.
Thanks.. Tom..

Thats it i have done
Never do that, it's cross posting and wastes peoples time. I've merged your two topics.
Understood. But i would be loosing more time if i argue .
Here i come for solutions and that is what matters for me which is still pending. Posts with Thousands of views are already there to drive TMC2209 with a motor, but no one has proper solution inside...
I would be be thankful for people who would help
Like I said I do not have time to play games. You have been asked many times for information which you have failed to supply. Without the needed information how can you expect an accurate and working answer. Good Luck!
Hi.
Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?
Hand drawn and photographed is perfectly acceptable.
Please include ALL hardware, power supplies, component names and pin labels.
Have you got gnd of ESP32 connected to gnd of 2209?
Thanks.. Tom..
Thanks.. Tom..
I already provided driver/dev kit name, connections, setup image, even code, motor type,.
Can you tell what is missing there
I given power supply to driver TCM2209 from ESP32 5V,GND pins.
But for driving motor, I given Voltage and GND externally
12V, GND).
I used these connection.
Something wrong in codes I think. Since Connection are simple and properly done as shown in picture.
Please let me know if error in image!
Hi, @pssingh
Sorry but there are no pin labels on the MCU.
Please reverse engineer your project and DRAW YOUR schematic.
Thanks... Tom...
The ESP is a 3.3V device. So Vio of TMC2209 must be 3.3V, not 5V. Standard schematics are useless. As @TomGeorge already pointed out, helpers need an exact schematic of your project to help.
I am backing out, the OP does not want to solve the problem. It would be relative simple to solve if we had the information asked for but the OP is an expert and is apparently testing us as th OP knows better what we need then we do.
I already attached it in thread previously. No Issues. A code i found which works for me
It rotates accelerates clockwise anticlockwise with good speed for 5 seconds when i ground GPIO21/22 , and deaccelerates to after that for 2 seconds. But i don't know how to use UART feature of TMZ2209 for current adjustment....?This is only help i need from anyone here...
My code is attached below..... Please ignore previous non working codes. I request to focus this one since i think i am near to solution...

On my code , i am struggling so much to achieve this logic. Can anyone help me for that, i tried so hard, but luck no luck worked, that would be my perfect solution if it works...
**Button 1 GPIO 21(PIN_BUTTON_1):
When grounded (LOW), the motor should move anticlockwise at a slow speed for the first 3 seconds.
After 3 seconds, the motor should continue moving anticlockwise at a faster speed for an 5 seconds.
Button 2 GPIO22(PIN_BUTTON_2):
When grounded (LOW), the motor should move clockwise at a fast speed for the first 5 seconds.
After 5 seconds, the motor should continue moving clockwise at a slow speed for an 3 seconds.** If i try changing something, things doesn't work as expected. Please help
