Cannot Define Software Spi in 0.5.1

[ghost]

Hello,

TMC2130Stepper driver = TMC2130Stepper(CS_PIN, R_SENSE, SW_MOSI, SW_MISO, SW_SCK); // Software SPI

i cannot define software spi in 0.5.1 version.I'm getting this error

src/main.cpp:28:81: error: call of overloaded 'TMC2130Stepper(int, double, int, int, int)' is ambiguous

but in version 4.5 everything is working fine.

Is there more to the error message? Is this one of the examples or your own project?

[ghost]

no.im getting in example projects of your library.Can you try to compile please ?

[ghost]

Calibrate_spreadCycle.ino example i think is about version 0.5.1 because i downgrade to 0.4.5 and it worked.

I can compile fine with Arduino IDE 1.8.9.

And there shouldn't be any ambiguity with

TMC2130Stepper(uint16_t pinCS, float RS = default_RS, int8_t link_index = -1);
TMC2130Stepper(uint16_t pinCS, uint16_t pinMOSI, uint16_t pinMISO, uint16_t pinSCK, int8_t link_index = -1);
TMC2130Stepper(uint16_t pinCS, float RS, uint16_t pinMOSI, uint16_t pinMISO, uint16_t pinSCK, int8_t link_index = -1);

It would help if your compiler gave the possible constructors it's trying to match against.

Hello, I´m also having this issue in the Software_SPI example:

exit status 1 call of overloaded 'TMC2130Stepper(int, double, int, int, int)' is ambiguous

A bit of background: I installed your dedicated "TMC2130Stepper" library first. I only had to replace the basic call in order to have customized MOSI,MISO, and CSK pins, in a copy of the Software_SPI example:

instead of: //TMC2130Stepper TMC2130 = TMC2130Stepper(EN_PIN, DIR_PIN, STEP_PIN, CS_PIN);

I used: TMC2130Stepper TMC2130 = TMC2130Stepper(EN_PIN, DIR_PIN, STEP_PIN, CS_PIN, MOSI_PIN, MISO_PIN, SCK_PIN);

The driver worked fine, it moved the motor without problems. Great job!

But then I saw that your "TMCStepper" repository was newer. So I uninstalled (deleted) the "TMC2130Stepper" library, and installed the "TMCStepper".

When trying the Software_SPI example of this other library, this error happens, and does not allow to compile. Any idea why?

[Danitegue]

the overload error dissapear by replacing:

TMC2130Stepper driver = TMC2130Stepper(CS_PIN,R_SENSE, SW_MOSI, SW_MISO, SW_SCK); // Software SPI

by

TMC2130Stepper driver = TMC2130Stepper(CS_PIN, float(R_SENSE), SW_MOSI, SW_MISO, SW_SCK); // Software SPI

but no idea why

I'm not getting this error with TMCStepper / Simple.ino example. How are you defining the R sense value?

[Danitegue]

Ok, I have seen the problem:

in your TMCStepper / Simple.ino example, the R sense var is defined in this way:

"#define R_SENSE 0.11f"

but in the TMCStepper / Software_SPI.ino example, the R sense var is defined as:

"#define R_SENSE 0.11"

So, is missing the last "f"
