Hello good-afternoon,
I know that common anode Led Displays are most suitable for use with the led matrix on IOW40, but can i use common cathode led displays? There is any problem on doing this?
Thanks

Re: LED Matrix!!
If you can build a driving circuit to fit common anode you can use them.

HI, good night,
Ok, let me see if i understand:
With the driving circuit presented on AN1 sheet i cant use common cathode led displays. Is that correct.
If so the displays presented on the circuit are common anode, right?
Thanks in advance

Re: LED Matrix!!
That depends on what kind of displays you use and how you want to arrange them. Since this is a matrix you can of course use common anode or cathode, it basically just affects how the LEDs are arranged within the matrix.
