10:28 PM rue_shop1: ok, so it worked
10:33 PM rue_shop1: but
10:33 PM rue_shop1: I think I'm gonna go with the analog method
10:33 PM rue_shop1: I'll have to wait for the duty of the phase detector to hit 50%
10:33 PM Tom_L: what worked?
10:33 PM rue_shop1: the DAC
10:33 PM rue_shop1: 12 bit i2c dac, I was going to change up the way I'm doing the peak detection, but
10:33 PM rue_shop1: expanding the idea is turning into a mess
10:33 PM rue_shop1: and I'm realizing that there seem to be no advantages
10:33 PM rue_shop1: most of the problems are circling around not knowing when I have the high and low peaks worked out
10:33 PM rue_shop1: what I'm worried about is having to wait like 4 seconds to get data for a 1Hz signal
10:33 PM rue_shop1: but it looks like if I have to wait, there is no avoiding it
10:35 PM Tom_L: hmm
10:36 PM rue_shop1: I wouldn't even be comfortable with a high speed ADC on the live signal, I'm not sure enough there couldn't be aliasing when reading 40Khz sines
10:37 PM Tom_L: i forgot what this was for
10:37 PM rue_shop1: filter profiler
10:38 PM rue_shop1: for everything from servos to digital stuffs
10:45 PM rue_shop1: filters are everything tom
