Hi all, I'm just starting to go through the Vybrid documentation, specifically the VF6. I know it is early, and that the documentation isn't very complete so far. My interest this minute is a PWM generator. I need a PWM to adjust the brightness of several indicator LEDs in my design. The datasheet doesn't mention PWM at all, but it appears that the VF6 uses a timer peripheral similar to those used on Kinetis parts that do claim PWM capability.
I'm using very efficient LEDs such that when all are turned on full brightness the draw is only 300uA. My battery powered device needs long life, and sleeps for long periods of time. So, I need any PWM that I use as little power as possible.
Assuming the VF6 does have PWM capability, here are my questions:
1. How much duty cycle control do I have?
2. Can the low power timer be used to generate PWM?
3. Which of the low power modes allows the PWM to generate (I want my LEDs lit when the design is sleeping).
