Help addressing 2 6276 LED drivers?

hi,

I have a subroutine to control 2 LED drivers, 1 has a 10 segment bar and the other has 2 x 7 segment numeric arrays.

So in the subroutine I have 2 statements, 1 for each driver. When I comment out either statment, the remaining driver works as expected. When both are uncommented, everything looks a mess.

These are Allegro A6276EA ICs, the Bar is an LedTech LL10000-G and the &-segment displays are KingBright SA03-12GWA.

Code snppet below, thanks in advance for any pointers.

bests,
Tobie
