CTRA, CTRB tutorials?

Steel

I have gone through the Propeller Objects download and through the other threads, and have found very little about working with the CTRs in the propeller.

Unfortunately, I don't understand how the Phs and Freq work together to create or read analog signals, and I would really like to do that.

Right now, the only objects in the object download for DAC, ADC work uses external chips.· I would like to create some objects for people that run the Timer features listed in the manual (Frequency Synthesis, Frequency measurement, Pulse Counting, Pulse Measurement, multi-pin state measurement, PWM, Duty cycle measurement, DAC, ADC, etc)

Unfortunately, I don't 'quite' understand how the PLLDIV, FRQ, PHS interact with each other.

Is there a tutorial or any information that better explains what they actually do, and how they work together?· The manual seems to just state that they accumulate to create a an Oscillator.

I would like to undersand these better so that I can master them and help others.

Is there anybody who could provide more insight, or point me in the right direction?

Thanks
Shaun

There is an application note on counters in the downloads section (where you get the manual) and there is an education lab using them (see in the sticky threads at the top of the forum).

Steel,

There is a Education Kit Lab... getting ready to be lauched. It has very clear examples... should be just what you are looking for.
