My previous post about speeding up multiplexing resulted in a display with
8x48 LEDs. As I suggested and read, the LEDs are becomming less bright
when more than 2 LEDs are on in a matrx of 8x48 >=.
Can anyone help me to calculate the resistor value I need to get bright LEDs.
Or, how can I caclulate this? Now I'm using a 100R per column which is
probably to much.
I have found many multiplexed led displays in public have a way too low
update frequency. Which cause headache all sorts of annoyances..
