ADXL via SPI

In some cases the ADXL via SPI won't work out of the box. We'll fix that :)

1. First let's configure the adxl in config files. Edit printer.cfg and add the following:

[adxl345]
cs_pin: host:None

[resonance_tester]
accel_chip: adxl345
probe_points: 60, 60, 20

2. Run ACCELEROMETER_QUERY in the fluidd/mainsail console to check if everything's working. The correct output look lke this:

If you're getting any errors, try running the command again as soon as possible after getting an error. If the problem persists there's a set of things that we can do.

3. Let's check what SPI address are available by running ls -la /dev/spi*

4. Update the [adxl345] config part by adding the spi_bus: spidevX.X according to the list you get from previous step and rerun ACCELEROMETER_QUERY command again:

Replace the X.X with number you got from the ls command

[adxl345]
cs_pin: host:None
spi_bus: spidev1.0 # or spidev1.1

If you're still getting errors we need to edit the host OS file /boot/armbianEnv.txt and add spi-spidev overlay.

For some strange reason using armbian-config doesn't seems to work. (You can try, though)

5. Edit the armbinaEnv file by running

nano /boot/armbianEnv.txt

The file should look similar to like the one below.

We need to add two things just below the line that starts with phrase overlays

param_spidev_spi_bus=1
overlays=spi-spidev

The final file should look like this

Why I didn't put the file for you to copy? Because it can vary from board to board, so it's better to just add the lines in correct place.

6. Redo the point 3 - you should get additional spi devices on the list

7. Redo the point 4. If everything went ok, you should be able to successfully check accelerometer status (look point 2)

Camera

Look in crowsnest logs for something like video0 / video1 Change your crowsnest.conf to match the camera that has been detected as a camera
