[Alternating displays]

Hello everyone,

i needs some help in my project on the M91.

i need to display 12 different variables on one display.

i understand the maximum number of variables on each display is 8.

i tried to split the variables to 2 displays and to alternate quickly between display but it didn't worked out.

it seems the alternating scan is too slow.

Does someone has an idea how can i solve this

thanks in advance
