[pi0]
## This affects Pi Zero(W) and Pi Zero2
## Due lag of RAM, limit GPU RAM
gpu_mem=128

[pi2]
gpu_mem=256

[pi3]
## Use 256 if 1Gb Ram Model!
# gpu_mem=128
gpu_mem=256


[pi4]
## Do not use more than 256Mb on Pi Model 4, it uses its own Management.
gpu_mem=256

[all]

## SPI Interface is enabled by default for Input Shaper
## This colides with Hyperpixel Display!
## Hyperpixel Screen uses the same Pin for Backlight.
dtparam=spi=on


## Enable Hardware UART for Serial Communication
## This also disables Bluetooth!
enable_uart=1
dtoverlay=disable-bt

## Enable I2C by default.
## This is used by Klipper's Host MCU
## See https://www.klipper3d.org/RPi_microcontroller.html#optional-enabling-i2c
## for destails.
## For MPU Accelrometer please use
## dtparam=i2c_arm=on,i2c_arm_baudrate=400000
dtparam=i2c_arm=on

## Disable libcamera (interferes with ustreamer, when using raspicams)
# camera_auto_detect=0

## Enable VideoCore at boot, needed for Crowsnest (Raspicams and DSI devices).
# start_x=1


### EXPERIMENTAL - Enable 64bit Kernel
### The 64-bit kernel will only work on:
### Raspberry Pi 3, 3+, 4, 400, Zero 2 W and 2B rev 1.2
### and Raspberry Pi Compute Modules 3, 3+ and 4.
# arm_64bit=1
