Picobilical Pi Hat

[Brystro]

I am trying to figure out the ADXL settings for the Pi HAT that came with my Picobilical kit.  I figured out the UART but need the Klipper settings for the ADXL.  Can someone help or point me to a link?  Thanks in advance.

This is the 'HAT'

Of course, the shaper settings will be replaced with yours !

shaper_freq_x: 95.6 ; suggested max_accel <= 26900 mm/sec^2
shaper_type_y: mzv  ; (vibrations = 0.0%, smoothing ~= 0.049)
shaper_freq_y: 65.2 ; suggested max_accel <= 12500 mm/sec^2

; -> accel limit 10000 mm/s²

Thank you!  That worked.  My logical brain couldn't comprehend cs_pin: rpi:None.  Thanks again!

Means there's no chip select management. Considering one device only on the SPI bus.
SPI requires as many CS than devices, while thre's one unique data/clock bus. SPI is a bit dumb.

Just have a look to the two pictures. Self explanatory.
