7i73 LCD shows rubisch

Yes naturaly two bits.

I will try to deliver halscope, I'm not very expierience with it till now. My feeling ist that it is not in lcd component.

I suspect more in data transfer.

i do not believe neither in emv, all is on clean labor table.

And suddenly started after an update. Before everything worked super on the first try.

P.s. Mabe in 1-2 hours i have it. Still on the road,( Train)

you can all confirm its related to the parameters commit?
The actual parameters are all the same, after startup?
The display data is one byte per cycle, in the process data? how is that synced, after the last character?
Is it possible to delay, or slow down the updates, to see better what is going on? or try a shorter string?

looking at the video, sometimes part of the text appears somewhere else. so it sounds like a sync problem.
there are pins/parameters to check for package errors in hm2_eth and sserial.

For the tcpdump:

I'm on stretch and that does not know the command tcpdump anymore and also my eth1 is now called enp0s25
If you are testing with older debian ..... that might be a point, as stretch is in my eyes still a beast ... maybe the reason...

I will try if there is a save way to get tcpdump again.
Mike

tcpdump may be in /sbin or /user/sbin and its likely you don't have a path setup for these

you can check with
locate tcpdump

if its not there you can
sudo apt-get install tcpdump

got it

here the few seconds long log... I switched trough the four pages of the lcd



Next will try to halscope needs probably more time ;-(

And here my (first) halscope.log
