Anyone used the TLC5940 with Imp?

Hi all,
I’m trying to drive a bunch of RGB LEDs using the TLC5940. There’s a lot of Arduino support, but I haven’t seen any references to using the Electric Imp.

I’m trying to use the SPI interface and example code but am stumped about the bytes needed to send to the TLC5940.
Any guidance or examples would be greatly appreciated!

I know it has been literally years… but did you happen to write a driver for the TLC5940? I just found a pile of them in my office so I figured I would put them to good use!

Generally seems pretty easy to use for display: just clock in 192 bits of data (12 bits each for all 16 channels). Have you tried it?
