is "shiftout" compatible with other shift registers with more segments?
for example 16 segments http://focus.ti.com/lit/ds/symlink/tlc5928.pdf
i want to control 64 led display (8x8) with as less chips are possible. (i know i can connect 8 single shift registers). i need the shift registers to be constant-curret too. And i need to be combatible with arduino syntax.
