EBB36 acceleromiter setup

[RevWizard]

Im attaching part of my printer.cfg file that defines the onboard acceleroiter in EBB36 V1.2
The klipper is not happy about this setup. Can someone advise why?
I get this message in the console :

Klipper reports: ERROR
Section 'spi_bus spibus' is not a valid config section

What is "spibus"? Spi busses normally have numbered names like "spi1" or "spi2a".

 

[shiftingtech]

Not to mention, where did you get any of that [spi_bus spibus] section? That's not a thing. Klipper defines the spi busses in its internal board definitions, not you

I didnt know that I can not define my own SPI bus. Im attaching the picture of my EBB36 pinout with description. It seems like the SPI bus name is SPI 2
Should I use this as the SPI bus name instead ?
like this:

[spi_bus SPI2]
mcu: EBBCan
sclk_pin: PB10
miso_pin: PB2
mosi_pin: PB11



[adxl345 my_adxl]
mcu: EBBCan
spi_bus: SPI2
cs_pin: EBBCanB12
axes_map: x,y,z

 

[RevWizard]

I tried already the above name and also SPI2a . Both still do not work

 

[shiftingtech]

Get rid of the entire [spi_bus whatever] section. That's not a thing.

The *only* thing you need for setting up the spi bus is the relevant entries inside the [adxl] section, spi_bus & cs_pin.

I do note that in their sample config for this board, btt uses software spi. It's possible there's a reason for that.

That worked fine setting up the config file
Thank you!

added this section right after and Im able to do tests
