--The custom Lynxmotion Smart Servo (LSS) serial protocol was created in order to be as simple and straightforward as possible from a user perspective ("human readable format"), while at the same time staying compact and robust yet highly versatile. The protocol was based on Lynxmotion's SSC-32 & SSC-32U RC servo controllers and almost everything one might expect to be able to configure for a smart servo motor is available.

--In order to be able to control each servo individually with commands, the first step should be to assign a different ID number to each servo (explained below).

There is currently no CRC / checksum implemented as part of the protocol.

  == Action Commands ==
--Action commands tell the servo, within that session, to do something (i.e. "take an action"). The types of action commands which can be sent are described below, and they cannot be combined with other commands such as queries or configurations. Only one action command can be sent at a time. Action commands are session-specific, therefore once a servo is power cycled, it will not have any "memory" of previous actions or virtual positions (described below on this page). Action commands are sent serially to the servo's Rx pin and must be sent in the following format:

Not all action commands have a corresponding configuration command and vice versa. More information about which configuration commands are retained when in RC mode can be found on the [[LSS - RC PWM page>>doc:lynxmotion-smart-servo.lss-radio-control-pwm.WebHome]]. Configuration commands are not cumulative, in that if two configurations are sent, one after the next, only the last configuration is used and stored. The format to send a configuration command is identical to that of an action command:

  == Virtual Angular Position ==
--The ability to store a "virtual angular position" is a feature which allows for rotation beyond 360 degrees, permitting multiple rotations of the output horn, moving the center position and more. In virtual position mode, the "absolute position" would be the angle of the output shaft with respect to a 360.0 degree circle, and can be obtained by taking the modulus (with respect to 360 degrees) of the value. For example if the virtual position is reported as 15335 (or 1533.5 degrees), taking the modulus would give 93.5 degrees (3600 * 4 + 935 = 15335) as the absolute position (assuming no origin offset).

++<div class="cmdcnt"><div class="cmdpad"></div><div class="cmdtxt">
++This command allows you to control when the RGB LED will blink the user set color (see RGB LED command for details). This is very useful when visually seeing what the servo is doing. You can turn on or off blinking for various LSS status. The command requires that the servo be RESET. Here is the list and their associated value:<div class="wikimodel-emptyline"></div>

++
++To set blinking, use CLB with the value of your choosing. To activate blinking in multiple status, simply add together the values of the corresponding status. See examples below:<div class="wikimodel-emptyline"></div>
++Ex: #5CLB0<cr> to turn off all blinking (LED always solid)<div class="wikimodel-emptyline"></div>
++Ex: #5CLB1<cr> only blink when limp (1)<div class="wikimodel-emptyline"></div>
++Ex: #5CLB2<cr> only blink when holding (2)<div class="wikimodel-emptyline"></div>
++Ex: #5CLB12<cr> only blink when accel or decel (accel 4 + decel 8 = 12)<div class="wikimodel-emptyline"></div>
++Ex: #5CLB48<cr> only blink when free or travel (free 16 + travel 32 = 48)<div class="wikimodel-emptyline"></div>
++Ex: #5CLB63<cr> blink in all status (1 + 2 + 4 + 8 + 16 + 32)<div class="wikimodel-emptyline"></div>
