I’m trying to follow the instructions for enabling hardware PWM (getting a MPU-6050 accelerometer)
Everything looks good, I have the PWA device present under /sys/class/pwm/pwmchip0/pwm0
however I’m getting a Unknown pin chip name ‘host’ due to the pin = host:pwmchip0/pwm0 config line
Any help would be very much appreciated.
You seems to be missing a “Linux MCU”. If you have installed it and started the service, you need this section in your config:
[mcu host]
serial: /tmp/klipper_host_mcu
In this section the “Linux mcu” is named host and you can then refer to it.
Thank you!
After I added the section I got another error about host mcu being shutdown. I ran FIRMWARE_RESTART and I think it fixed things. I added both logs.
Really appreciate the help.
