Incorrect pins in the example .cfg

[Donpilkerton]

In the example Stridemax_dual.cfg it appears that pins spi_software_mosi_pin: stridemax_dual:gpio4 spi_software_miso_pin: stridemax_dual:gpio3

are incorrect per your pin out diagram of the rp2040. They should be

spi_software_mosi_pin: stridemax_dual:gpio3 spi_software_miso_pin: stridemax_dual:gpio4

These pin outs being incorrect lead me to spending hours troubleshooting "Unable to write tmc spi 'stepper_x' register GLOBALSCALER". I am one of those individuals that is not super versed in what causes these kinds of errors so it was time consuming.

I know the product is new but proper documentation on how to properly flash and implement this device should have been organized pre release date. There is virtually NO information on this.

Below is your example config with the pins backwards, If this could be fixed or if I am in error could you please explain. I can confirm after swapping these pins I am able to use the control board properly.

You will need to configure a neopixel (or other addressable led, such as dotstar). See

https://www.klipper3d.org/Config_Reference.html#neopixel for configuration details.

And you can get sb led MACRO here: https://github.com/PrinterConfigs/DoomConfig/blob/master/stealthburner.cfg

Or here https://github.com/sttts/voron-klipper-config/blob/master/stealthburner_leds.cfg

It's strange why your configuration is different from ours. What is known so far is that the early engineering samples have this configuration, and later batch products have exchanged MOSI and MISO to meet the needs of RRF using hardware SPI.

My config is not different. Your initial configuration was wrong. My issue that I submitted is what was the cause for having your initial configuration fixed. I spent hours trying to figure out what the problem was because you all did not have documentation or the proper configuration listed on your GitHub.

Thank you very much for your feedback. I will check this problem further and see what is wrong. Do you have instant chat methods such as discord or FB? I want a picture of your board to have a look.
