I'm using these:http://www.olimex.cl/pdf/Components/FYM-20881ABxx.pdf
- 8 pins for controlling line (1,2,3,4,21,22,23,24)
- 8 pins for green (1 resistor on each one of those lines)
- 8 pins for red (1 resistor on each one of those lines)
I'm thinking of connecting all the 'colosr' bus together and 'multiplexing' the control line.
I would take me 8 AND ports for each matrix, summing up to 32 AND ports.
4 Selection bits, one for each matrix, no binary. One wire per matrix.
But with 4 gates per IC it would take a lot of them just to make this board. Does anyone know an IC with more than 4 gates?
On my arduino code I would have a boolean matrix and a timer set to update the board every milisecond (or less, if I need) for the current matrix state.
I'm wondering if it would be too much for it to handle... Pretty sure it isn't, but I'm asking just in case (:
What do you guys think of this idea? I never did something like this and that's what I came up with.
