Hi Bruce, yes that worked (but I would expect nothing less from you )

But why ?

- I've got a period of $07E8 which is 2024 in decimal
- I ramp duty to 2024 which is seems is not 100% of a period (led watching was misleading, I guess, because one channel was ramping 0-25% (?) and the other 100-75% which isn't really much of a change in output intensity)
- so why does a duty cycle of 8000 get me 99% ?
