Hello :)

so you want to change the LCD to a VFD ?

Can you post a Datasheet from it?
itsmyfault...
it is a homemade driver
4 digit 7 segment
driven with multiplex
and the multiplexing is been done with an cd4017
and i am thinking of writing the 7 segments with an 74hc595

now i need 12 pins for everything
with a 74hc595 i onley need 5

as long as the sensor can be written as a vari able i can show it

i am gonna cycle trough the funktions with a button
the MultiDisplay uses the Seeeduino Mega, that has more than enough free I/O, you could easily connect your display with 12 lines :)
itsmyfault...
i/o pins is not the problem

we have shift registers for that

and becaus of space i have to make my own pcb
the mega would not fit
