I think there is a simple answer.

Why not make a DAC, and connect the output to the input of an H-bridge circuit and connect it's output to the motor?

If you do a search on google for H-bridge circuit, and you do a search for R/2R ladder, you could end up with results.

Now connect the digital input of the dac to the low-bit outputs of a counter IC of your choice.

Once you have that, adjusting the motor speed is as simple as triggering the clock pin of the counter.

Try reading the thread! - your answer is completely wrong, in EVERY respect!.
In another thread, Mstechca proposed the same idea. I asked him how he proposed to connect a DAC, which has an analog output, to an H-bridge, which has a digital input. I don't believe he replied.
