TMC7300 by TMCSerial from bread-wolf

Hello Together,

I am trying to understand the library TMCSerial on Github from bread-wolf and get it to work for the TMC7300.

My code, after putting all the .h and .cpp files in the folder, looks like this:

#include"TMCSerial.hpp"
#include"TMCField.hpp"

TMCSerial TMC7300(Serial, 115200, 0);

void setup() {
  TMC7300.begin();

  /* Use the external capacitor mode for TMC7300 */
  TMC7300.writeField(TMC7300_EXTCAP, 1);

}

void loop() {
  /* Check if driver is in error state */
  if (TMC7300.readField(TMC7300_DRV_ERR) == 1)
  {
      /* Do something... */
      TMC7300.writeField(TMC7300_PWM_A, 125); // drive Motor A 50% forward
  }

}

But I get the error:
'TMC7300_EXTCAP' was not declared in this scope

Then I found this part in the TMC7300_Register.h file.

So I included the following line (and also the TMC7300_Registers.h file) :

#include"TMC7300_Registers.h"

But I get the same Error message.

I am not sure if I have understood the issue with the classes and .cpp .hpp files correctly?
To understand, I just need a simple way to make one of the two motors from the TMC7300 turn at one speed.

Thank you to all the experts.

Many greetings,
Toto

Installing libraries into the IDE world needs to be done in a certain way. Copying those files might not be be way. I made mistakes when I first dived into that jungle.

Maybe You can find help within the IDE, how to download libraries. Else, the best I can tell is Google on "Arduino + libraries".

Thank you very much for your advice.
I had also initially tried to install the zip file TMCSerial and TMCField as libraries via zip. This worked without an error message.
However, the same error message appears here.

Therefore I tried to follow the instructions on bread-wolf's Github page.

So my guess is that I am using the wrong declaration of classes or objects here, even though I followed the instructions on bread-wolf's github page in terms of the C++ code.

many thanks.

Do they refer to the Arduino IDE?
I've never seen any include of hpp, or cpp files in the IDE environment.

Facing a zipped library it needs unpacking and after that an installation to the IDE library folder. I'm likely wrong on some point but as a brief description, I think it might give You some aha.

It's more than a C## matter. It's about the IDE environment.
