[Swlug] LED drivers

I have a TM1637 card for Arduino/Raspberry. So far none of the libraries to make it function actually work for me. Thus I'm thinking of writing my own. The TM1637 card seems to have 4 direct connections to the TM1637 chip aboard and of course a shared common with the 4, 7-segment LED digits aboard. 

I downloaded the titanmec(dot)com manual for the TM1637. It looks helpful but I'm a little puzzled by some of it. It looks like I need to send a series of pulses on the clock line and then send zero or 1 pulses on the data line in time with the clock line to transfer data. I'm reading it as to send 101

clock 1, data 1
clock 0, data 0
clock 1, data 0
clock 0, data 0
clock 1, data 1.

Am I correct or am I misreading it?
