  = Serial Protocol Concept =
--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 compact and robust yet highly versatile. The protocol was based on Lynxmotion's SSC-32 RC servo controller and almost everything one might expect to be able to configure for a smart servo motor is available.

--In order to have servos react differently when commands are sent to all servos in a serial bus, the first step a user should take is to assign a different ID number to each servo (explained below). Once this has been done, only the servo(s) which have been assigned to the ID sent as part of the command will follow that command. There is currently no CRC / checksum implemented as part of the protocol.

Once this has been done, only the servo(s) which have been assigned to the ID sent as part of the command will take action. There is currently no CRC / checksum implemented as part of the protocol.
  == Session ==
  A "session" is defined as the time between when the servo is powered ON to when it is powered OFF or reset.
--Note that for a given session, the action related to a specific commands overrides the stored value in EEPROM.

  == 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:

++== Configuration Commands ==
++
++Configuration commands affect a servo's default values which are written to the servo's EEPROM and are retained in memory after the servo loses power or is reset. Some configuration commands affect the session, while others do not (see each command for details). Not all action commands have a corresponding configuration and vice versa. More information about which configuration commands are retained in RC mode can be found on the [[LSS - RC PWM page>>doc:Lynxmotion Smart Servo (LSS).LSS - RC 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:
++
++1. Start with a number sign # (U+0023)
++1. Servo ID number as an integer
++1. Configuration command (two to three letters, no spaces, capital or lower case)
++1. Configuration value in the correct units with no decimal
++1. End with a control / carriage return '<cr>'
++
++Ex: #5CO-50<cr>
++
++This assigns an absolute origin offset of -5.0 degrees (with respect to factory origin) to servo with ID #5 and changes the offset for that session to -5.0 degrees. Once the servo is powered off and then powered on, zeroing the servo will cause it to move to -5.0 degrees with respect to the factory origin. Configuration commands can be undone / reset either by sending the servo's default value for that configuration, or by doing a factory reset (clears all configurations) described below.
++
  == Query Commands ==
--Query commands request information from the servo. They are received via the Rx pin of the servo, and the servo's reply is sent via the servo's Tx pin. Using separate lines for Tx and Rx is called "full duplex". Query commands are also similar to action and configuration commands and must use the following format:

--Configuration commands and corresponding values affect a servo's defaults which are written to and read from the servo's EEPROM. These configurations are retained in memory after the servo is reset or power is cut / lost. Some configuration commands affect the session, while others do not.

--This configures an absolute origin offset ("CO") with respect to factory origin to servo with ID #5 and changes the offset for that session to -5.0 degrees (50 tenths of degrees). Once the servo is powered off and then powered on, zeroing the servo will cause it to move to -5.0 degrees with respect to the factory origin and report its position as 0 degrees. Configuration commands can be undone / reset either by sending the servo's default value for that configuration, or by doing a factory reset (clears all configurations) described below.
--
  **Session vs Configuration Query**
--By default, the query command returns the sessions' value. Should no action commands have been sent to change the session value, it will return the value saved in EEPROM which will either be the servo's default, or modified with a configuration command. In order to query the value stored in EEPROM (configuration), add a '1' to the query command:
++By default, the query command returns the sessions' value. Should no action commands have been sent to change the session value, it will return the value saved in EEPROM from the last configuration command.
--Ex: #5CSR20<cr> immediately sets the maximum speed for servo #5 to 20rpm (explained below) and changes the value in memory.
++In order to query the value in EEPROM (configuration), add a '1' to the query command.
--After RESET, a command of #5SR4<cr> sets the session's speed to 4rpm, but does not change the configuration value in memory. Therefore:
++Ex: #5CSR20<cr> immediately sets the maximum speed for servo #5 to 20rpm (explained below) .
--#5QSR<cr> would return *5QSR4<cr> which represents the value for that session, whereas
++After RESET: #5SR4<cr> sets the session's speed to 4rpm.
++#5QSR<cr> would return *5QSR4<cr> which represents the value for that session.
++
  #5QSR1<cr> would return *5QSR20<cr> which represents the value in EEPROM
  == 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).

  #1D2100<cr> This second position command is sent to the servo, which moves it to 210.0 degrees (orange arrow)
--#1D-4200<cr> This next command rotates the servo counterclockwise to a position of -420 degrees (red arrow), which means one full rotation of 360 degrees plus 60.0 degrees (420.0 - 360.0), with a virtual position of -420.0 degrees.
++#1D-4200<cr> This next command rotates the servo counterclockwise to a position of -420 degrees (red arrow), which means one full rotation of 360 degrees,  stopping at an absolute position of 60.0 degrees (420.0 - 360.0), with a virtual position of -420.0 degrees.
  Although the final physical position would be the same as if the servo were commanded to move to -60.0 degrees, the servo is in fact at -420.0 degrees.

++====== __14. Angular Stiffness (**AS**)__ ======
++The servo's rigidity / angular stiffness can be thought of as (though not identical to) a damped spring in which the value affects the stiffness and embodies how much, and how quickly the servo tried keep the requested position against changes.
++
++A positive value of "angular stiffness":
++
++* The more torque will be applied to try to keep the desired position against external input / changes
++* The faster the motor will reach its intended travel speed and the motor will decelerate faster and nearer to its target position
++
++A negative value on the other hand:
++
++* Causes a slower acceleration to the travel speed, and a slower deceleration
++* Allows the target position to deviate more from its position before additional torque is applied to bring it back
++
++The default value is zero and the effect becomes extreme by -4, +4. There are no units, only integers between -4 to 4. Greater values produce increasingly erratic behavior.
++
++Ex: #5AS-2<cr>
++
++This reduces the angular stiffness to -2 for that session, allowing the servo to deviate more around the desired position. This can be beneficial in many situations such as impacts (legged robots) where more of a "spring" effect is desired. Upon reset, the servo will use the value stored in memory, based on the last configuration command.

Numbered stickers are provided to distinguish each servo after their ID is set, though you are free to use whatever alternative method you like. The servo must be RESET or power cycled in order for the new ID to take effect.

--A servo's baud rate cannot be set "on the fly" and must be configured via the CB command described below. The factory default baud rate for all servos is 9600. Since smart servos are intended to be daisy chained, in order to respond to the same serial bus, all servos in a project should ideally be set to the same baud rate. Setting different baud rates will have the servos respond differently and may create issues. Available baud rates are: 9600 bps, 19200 bps, 38400 bps, 57600 bps, 115.2 kbps, 230.4 kbps, 250.0 kbps, 460.8 kbps, 500.0 kbps. Servos are shipped with a baud rate set to 9600.

--====== __A1. Angular Stiffness (**AS**)__ ======
--
--The servo's rigidity / angular stiffness can be thought of as (though not identical to) a damped spring in which the value affects the stiffness and embodies how much, and how quickly the servo tried keep the requested position against changes. There are no units.
--
--A positive value of "angular stiffness":
--
--* The more torque will be applied to try to keep the desired position against external input / changes
--* The faster the motor will reach its intended travel speed and the motor will decelerate faster and nearer to its target position
--
--A negative value on the other hand:
--
--* Causes a slower acceleration to the travel speed, and a slower deceleration
--* Allows the target position to deviate more from its position before additional torque is applied to bring it back
--
--The default value for stiffness depending on the firmware may be 0 or 1. Greater values produce increasingly erratic behavior and the effect becomes extreme below -4 and above +4. Maximum values are -10 to +10.
--
--Ex: #5AS-2<cr>
--
--This reduces the angular stiffness to -2 for that session, allowing the servo to deviate more around the desired position. This can be beneficial in many situations such as impacts (legged robots) where more of a "spring" effect is desired. Upon reset, the servo will use the value stored in memory, based on the last configuration command.
