Re: [micro-manager-general] Question about Zeiss CAN29 messaging

[Wiktor P. <wik...@ki...>]

Thanks Matthias.

So from what I understand this may require doing some initial dev work on a Windows machine with the MTB SDK installed? I intend to interface with the microscope from Linux if possible.

Essentially, I should monitor the bus while issuing commands to capture their structure, then reconstruct the raw messages with a bespoke parser + serial interface in my language of choice?

Are the utilities to monitor the CAN bus included in the SDK or are they from a third party?

Thanks,

Wiktor

The raw messages have a preamble and postamble and occurrences of 0x10 are escaped.

I have recently build my own library to talk to an observer and developed it against the Zeiss internal simulation. See also my previous message on this topic some days ago.

I found the messages to be well structured and the MTBMonitor and MTBTest very helpful to decode the messages and their format.

Best,
Matthias

Hi Wiktor,

I'm wondering (speaking from total ignorance here), whether this is just a standard CAN bus (extended frame=29bit) interface:

Hi,

Quick question: Is there any kind of documentation of the low-level/platform independent communications protocol for the CAN29 bus? Or am I stuck inferring the byte commands/responses from the implementation in the Zeiss CAN29 device adapter..?

Cheers,

Wiktor
