I picked up a LED matrix today assuming that the rows and columns will be in order(rows on one side and columns on the other side) however the matrix i picked up seems to have no such pin outs. Is this common with LED matrices? I haven't checked up the datasheet(dont think it will have one)
My rg led matrix's (and many others', I think) pinouts are numbered like a dip chip. The pins go red col 1, green col 1, row 1, red col 2, etc... for all of the 24 pins. Maybe yours is similar?
