Solved Accelerometer causes Duet 2 Wifi to crash?

[kuhnikuehnast]

Hi there- I have a strange error:
I connected an Accelerometer.
As soon as I post a M956 command the Board "crashes" (nothing happens and after a few seconds the board reboots). I can also find the file created in the accelerometer folder but it is empty...?
Any suggestions what I am doing wrong?

greetings kuhni

[kuhnikuehnast]

Just tried the other duet board I own (a cartesian printer) - there a file is created with the message

Sample,X,Y,Z
Failed to collect data from accelerometer

very strange...?

[kuhnikuehnast]

another strange behavior:
I can adress the Accelerometer with the command:

M955 P0 I46 C"spi.cs4+spi.cs3"

but if I then want to change something and post the code again (e.g. to change the Frequency)

M955 P0 I46 C"spi.cs4+spi.cs3" Q500000

I get the error

M955: Accelerometer not found on specified port

is this normal? Do you have to reset the Board to "re-activate" the possibility to declare an M955 command?

[dc42]

@kuhnikuehnast I'm not sure why that is happening, however you don't need to repeat the M955 C parameter or I parameter when you just want to change the data collection parameters.

If the board reboots unexpectedly, please run M122 as soon as DWC has reconnected, and post the output here.

@kuhnikuehnast I suspect that there may be a problem with the INT connection from the accelerometer to the Duet spi.cs3 pin.

[kuhnikuehnast]

@dc42 so what should I do? When i connect the same board (and cable) to the other board it "works" - as mentioned above... "failed to collect data"

[kuhnikuehnast]

@dc42
I now tried something else:

• I switched the CS and INT1- Pin (so I declared the M955 to:
  M955 P0 I46 C"spi.cs3+spi.cs4"
  instead of
  M955 P0 I46 C"spi.cs4+spi.cs3"

but as soon as I ran the code:
M956 P0 S1000 A0

I got another crash. In this time this was the M122:

Do you see something different? So is my Duet broken? Or how could I solve this problem?

Hope you can help me!

[dc42]

@kuhnikuehnast it could be that writing to the SD card is taking too long. You could try a new SD card. Alternatively, reduce the number of samples you are collecting, for example to 500.

[kuhnikuehnast]

@dc42 tried now only 10 samples by
M956 P0 S1000 A0
same crash...

[kuhnikuehnast]

@dc42 btw what is the biggest size possible for the SD-Card? So I'll get to grab a new one...

sorry, got it already- so I'm out now heading to a store to get a SanDisk Extreme Pro 32 GB mircoSD cross fingers for me that this will solve the problem!

[kuhnikuehnast]

I think I solved the problem:

• it wasn't the SD-card- but as I changed the cable and re-crimped an USB-3-cable everything now seems to work!
