New Scope Demoboard from Batronix
blurpy:
I like this demo board, and I'm learning a lot about features I haven't explored much.
But when I got to step 3.5, to test the MSO parallel bus interface with my Siglent SDS2000X+, the scope seems to be lacking in capabilities.
If I'm understanding it correctly, the Siglent "decodes" parallel signals in the digital menu instead of the decode menu where it can decode serial signals.
And there is no option to see the decoded ASCII value:
Converting the hex shown here, "42 61 74 72 6f 6e 69 78", to ASCII using any online converter produces the text "Batronix".
So it seems like an incredibly simple operation to do. Am I missing something perhaps?

Hi,
I'll have to have a look at how I set it on my 2k+ HD:
And I have an SDS2104X+ here right now, I could test it directly, I'll get back to you later.
EDIT: Ah, now I see...
Martin72:
Just test it on the SDS2104X+ from work (therefore the inverted pics), here we go:
1. According to the demo manual page 45 for CAN decoding set switch 1 to "0" and switch 2 to "A".
2. Activate "Digital" on your scope, then activate "Decode"
3. Set decode signal to CAN, source CAN_H at D07.
4. Set Baudrate to 20kbit/s
It´s just an example, you could also try LIN or Manchester, important to know is that if you want to decode something from the parallel bus, digital must be active otherwise you couldn´t select the digital channels in the decoder menu as a source.
And only the decoder section allows to display the values in ASCII.
Edit: Only serial decoder avaible

Thanks for looking into this Martin72. Seems like you are setting up serial decoding using one digital line from the parallel bus (section 3.6), and not parallel decoding using 7 digital lines from the parallel bus (section 3.5). What if you try to setup the scope for section 3.5, and see if you have more luck getting the ASCII value somehow?
Martin72:
That's right,
I overlooked that, a good hint.
I couldn't find ASCII here either, that would be something for the wish list.
