03:22 AM Jak_o_Shadows: Torn between putting the values as quarter degrees, or making the values as 2us
03:28 AM Jak_o_Shadows: For the serial servo
04:41 AM Jak_o_Shadows: I guess the question comes down to what level I want to control the servos at
04:42 AM Jak_o_Shadows: and honestly, I think I want that to be at the angle level.
04:42 AM Jak_o_Shadows: maybe the calibration values should be programmed over serial....
05:30 AM veverak: hmm
05:30 AM veverak: I am using LX-15D (now from hiwonder)
05:31 AM veverak: I have .pdf with protocol documentation somewhere
05:31 AM veverak: I would get inspired by it if I were you
05:31 AM veverak: or generally, find documentation for some allready existing servo and get inspired
05:31 AM veverak: or jump to CAN and implement their motor standard :)
05:31 AM veverak: also dynamixel protocol may be inspiration-worthy
05:34 AM Jak_o_Shadows: On my PCB's, I have CAN transceiver pads
05:34 AM Jak_o_Shadows: but I also have solder bridges just to do it serial
05:37 AM Jak_o_Shadows: Rue's done most of the protocol work - theoretically that's got get/set position, set cache, execute cache, get current
05:38 AM Jak_o_Shadows: and chaining listen, so you can just send new positions through
05:38 AM Jak_o_Shadows: but I haven't implemented any of the gets
05:38 AM Jak_o_Shadows: and his protocol gives you 1024 values to use for the position
05:38 AM Jak_o_Shadows: but doesn't specify units
06:36 AM veverak: yeah, which is normal
07:58 AM Phrkd is now known as Phreaked
09:26 AM rue_mohr: :)
09:27 AM rue_mohr: glad something I'v done is comming in handy for someone
