This is a report on constant current function requested. It works relatively well for moderately low resistant circuits. In this test I have a 10Ω load and it works very well, albeit a lot slower than an analog constant current supply. So, while my concerns about speed were well founded this is a reasonably useful way to control constant currents. Will this feature make it into the final design? I'm not sure... If I thought constant current was vital, I'd prefer to do it in the analog domain which is generally faster than doing things digitally. Is this a reasonably useful feature? Yes. It does still require that you add a little impedance to the circuit to prevent your LEDs from popping (because of the speed the circuit reacts), but much less than required without any constant current control.
