Hi Nick controllers nowadays are easily fast enough to do very smooth fading even when dimmed. I do 6 iterations (one for each digit) of 1000 counts (for dimming and fading of each digit) with a minimum digit on time of 1000 and a maximum digit on time of 999. I calculate the switch from old to new digit based on the percentage of the fade that is done and the dim factor. This gives smooth dimming when fully on, or fully dimmed, or anywhere in between.
There's still easily enough time to do all the other work that's needed outside the loop. You have one of my early clocks modules don't you? I should arrange a firmware update for you, the hardware is largely the same, but the firmware has come on leaps and bounds.
