01:08 AM rue_shop1: happy new year!
01:15 AM rue_shop1: I'm the only real person left on the internet
01:37 AM rue_shop1: I'm at 11:24pm
02:08 AM rue_shop1: happy new year!
02:08 AM rue_shop1: this one was mine, i missed the countdown
02:08 AM rue_shop1: I will likley miss the rest of the year too
03:54 AM rue_mohr: hmm, do I want to use a M8, M88, M32, or M328 for this servo project...
03:54 AM rue_mohr: I'm leaning towards M8
03:54 AM rue_mohr: tho I have libraries already for M328
03:55 AM rue_mohr: I dont think I want to use M32
03:55 AM rue_mohr: even M8 is a space hog
03:55 AM rue_mohr: I suppose if I wanted a challange I could use the stm32
03:56 AM rue_mohr: but I'm having a hard enough time getting anyting done already
03:56 AM rue_mohr: ok, m8, m88
03:57 AM rue_mohr: ok, adc feedback, dpwm, P, and adc control
04:00 AM rue_mohr: ok, I have that for m32
04:00 AM rue_mohr: so, this might not be hard
06:23 AM nohit: happy new year
06:24 AM rue_shop1: happy new year
06:25 AM rue_shop1: ok, the corner freq of the servo is 1.88Hz
06:47 AM rue_mohr: ok, so
06:47 AM rue_mohr: at Kp=7 I get a 5Hz oscillation
06:47 AM rue_mohr: and 45 degree phase shift (sine wave in) is at about 1.88Hz with a *bit* of gain
06:49 AM rue_mohr: I didn't expect to see resonation, but thats why I'm doing this
06:49 AM rue_mohr: so, the filter needs to pick up the high freqs and shave off a bit of a spike
10:52 AM nohit: so which one did you choose ?
02:02 PM rue_mohr2: M8
