Analog Multiplexing issue
« on: June 12, 2019, 08:06:10 pm »
Hi,

I have analog multiplex connected inside ECU (done by order during ECU build) and all seems to be working in steady state. It is switching, sometimes it is like ECU takes few sec till it start switching analogs.  >> Engine stopped "noise "clearing out VIDEO >> https://youtu.be/vZWfPuv0T38


However It is really strange behavior with engine running, it seems to me like lack of speed or something .. result is useless analog inputs.   >> Engine running  VIDEO :https://youtu.be/htHuMvQeEzE

Firmware : 1.38

Anybody who made it ?

Yea, I double check that. Also tried  version 1.41, still the same. Last time I test it was 4 days ago.

Hmm, wasn't even aware about it :D

However, unchecked, config burned, nothing has changed.
I checked ini files before try, it download 4 new files but nothing has changed for me.
Also I tried to rollback to 1.38, still the same.

Any other idea what to check ?
I am considering if it takes maybe noise of the sparks or something, but it is not periodical, doing it even in idle and randomly ..

Might it be related to SDcard logging ?  I was trying to do log, to check and share but you know.. short file that I makes seems to be weird for me.
