Bit Angle Modulation (BAM) in a PIC

[Darrel Taylor]

Since MIBAM uses a completely ASM interrupt handler, it would be much easier to make it compatible with DT_INTS instead of the other way around.

However, if you're just measuring pulse widths ... the use of Timer3 and a CCP module (Capture mode) might be more applicable. And you won't need Interrupts for that, although they can still be used with LOW Priority. It'll be more accurate with the CCP too.

The HIGH Priority interrupts will affect the "Timing" of LOW Priority ints.
The resolution of a Pulse measurement using LP ints (without CCP) will always suffer.

what means "LP ints"? Are u talking about jitter problem? U should update T0 then (for example) in every interrupt to avoid that. If u going to use CCP with prescalers/postscalers then will get jitter error too.

What refresh rates and bit resolutions have u achieved?

p.s. very nice aproach, congratulations. and sorry 4 poor english.(

"LP ints" means Low Priority Interrupts on an 18F.

High Priority Interrupts can interrupt Low Priority Interrupts.
So trying to measure times exactly with Low Priority interrupts will not give very good results unless you are using hardware peripherals, like the CCP module.
