Currently this Arduino project uses the TMCStepper library to configure a set of six(6) TMC stepper drivers. Once configured the TMC drivers are no longer communicated with. Having configured the TMC driver slows down the main loop even though there is no TMC code in that loop. There looks to be an timer interrupt running in the back ground even though the driver is not being communicated with. The attached sample codes main loop with the TMC setup disabled is nearly 4 times faster than the one with the TMC started. I need the code rewritten to setup the TMC drivers and then stop communicating with them so the main loop runs at the faster speed. The two programs supplied are snippets of the full code but shows the problem. 1) [login to view URL] - If the code in the void setup() for setting up the TMC stepper drives is active, the main code loops at 420kHz. 2) [login to view URL] - If the TMC code is commented out it loops at 1450mHz. Programmed in PlatformIO using Arduino framework on a Weact STM32F411 BlackPill.

Hello, I have (4) years of experience in Arduino, and to cut things short now, I think I might be able to help you, if you give me the link to the library you are using, I will take a look at it and give a solution. It will not be my first time diving into libraries header files and even editing them, so can we communicate so we can exchange more info? Thank you and good luck.
