Multiplexer not working well?

claudioBela

Please my multiplexer doesn't seem to work correctly.

I show my screenshot.

The same Analog Input is shown at the same position in matrix even if I'm using only 7.0 pin of multiplexer.
Could anybody help me with this issue? After many attempts I'm not able to use correctly the multiplexer.
Only pin 0.0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 seems to get the Voltage Input but the measure is repeated and shown over all channels in same position, not correctly.
I changed timing of metro and used Digital out Pin 11 at 1 level (3.3 Volt).
Need help, please

Same using cpp Spectrum and Display examples instead of Pure Data example, as shown in screenshots.
Thanks for any help

can you try updating the core code on your boar? The image you received with the board is probably about 1 year old so it won't contain a fix that should fix the issue you are having.

Thank you 3.8h version but now with patches.....
The multiplexer is working as expected, last test when all the bank of 16/32/64 pots will be ready to be used.
A normal instability is detected on open terminals at the multiplexer open on air pins, closed to the connected pin with controlled voltage.
Thanks, regards
