8 8  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.

17 -Note #2: During the power-on / reset process the LSS cannot accept commands for a small amount of time (1.25 s).
18 -You can ensure the LSS is ready by using a query command to check for response (ex: #[id]Q\r or #[id]QID\r). If the LSS is ready for commands (initialized) it will respond to the query. A timeout between 50-100 ms is recommended.

22 22  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:

50 +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 (see each command for details). Not all action commands have a corresponding configuration 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).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:

60 +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.

401 401  
402 -Ex: #5LED3<cr>
380 +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.
403 403  
404 -This action sets the servo's RGB LED color for that session.The LED can be used for aesthetics, or (based on user code) to provide visual status updates. Using timing can create patterns.
382 +A positive value of "angular stiffness":
405 405  
406 -0=Off (black); 1=Red 2=Green; 3=Blue; 4=Yellow; 5=Cyan; 6=Magenta; 7=White;
384 +* The more torque will be applied to try to keep the desired position against external input / changes
385 +* The faster the motor will reach its intended travel speed and the motor will decelerate faster and nearer to its target position
407 407  
408 -Query LED Color (**QLED**)
387 +A negative value on the other hand:
409 409  
410 -Ex: #5QLED<cr> might return *5QLED5<cr>
389 +* Causes a slower acceleration to the travel speed, and a slower deceleration
390 +* Allows the target position to deviate more from its position before additional torque is applied to bring it back
411 411  
412 -This simple query returns the indicated servo's LED color.
392 +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.
413 413  
414 -Configure LED Color (**CLED**)
394 +Ex: #5AS-2<cr>
415 415  
416 -Configuring the LED color via the CLED command sets the startup color of the servo after a reset or power cycle. Note that it also changes the session's LED color immediately as well.
396 +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.

422 -Ex: #5G-1<cr>
402 +Ex: #5CAS<cr>
423 423  
424 -This command will cause servo #5's positions to be inverted, effectively causing the servo to rotate in the opposite direction given the same command. For example in a 2WD robot, servos are often physically installed back to back, therefore setting one of the servos to a negative gyration, the same wheel command (ex WR30) to both servos will cause the robot to move forward or backward rather than rotate.

408 +The angular holding stiffness determines the servo's ability to hold a desired position under load. Values can be from -10 to 10, with the default being 0. Note that negative values mean the final position can be easily deflected.
429 429

439 439  
440 -A servo's identification number cannot be set "on the fly" and must be configured via the CID command described below. The factory default ID number for all servos is 0. Since smart servos are intended to be daisy chained, in order to respond differently from one another, the user must set different identification numbers. Servos with the same ID and baud rate will all receive and react to the same commands (assuming same baud rate).

446 -When using the query ID command, it is best to only have one servo connected and thus receive only one reply. This is useful when you are not sure of the servo's ID, but don't want to change it. Using the broadcast command (ID 254) with only one servo will have that servo reply with its ID number (assuming the query is sent .

In most situations each servo must be set a unique ID, which means each servo must be connected individually to the serial bus and receive a unique CID number. It is best to do this before the servos are added to an assembly. 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.

456 -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 115200. 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 115200.

Using the command #5CRC<cr> or #5CRC3<cr> which requests that the servo remain in serial mode still requires a RESET command.
537 +This configuration command means the servo, when set to RC mode, will immediately move to an angle equivalent to having received an RC pulse of 1550 microseconds upon power up. Sending a CFP command without a number results in the servo remaining limp upon power up (i.e. disabled).
572 572  
573 -Important note:** **To revert from RC mode back to serial mode, the [[LSS - Button Menu>>doc:lynxmotion-smart-servo.lss-button-menu.WebHome]] is required. Should the button be inaccessible (or broken) when the servo is in RC mode and the user needs to change to serial mode, a 5V constant HIGH needs to be sent to the servo's Rx pin (RC PWM pin), ensuring a common GND and wait for 30 seconds. Normal RC PWM pulses should not exceed 2500 milliseconds. After 30 seconds, the servo will interpret this as a desired mode change and change to serial mode. This has been implemented as a fail safe.

591 591  
592 -Note that after the CONFIRM command is sent, the servo will automatically perform a RESET.
557 +Ex: #5QDT<cr> might return *5QDT6783<cr>
593 593  
594 -====== __30. **UPDATE** & CONFIRM__ ======
559 +The query target position command returns the target angle during and after an action which results in a rotation of the servo horn. In the example above, the servo is rotating to a virtual position of 678.3 degrees. Should the servo not have a target position or be in wheel mode, it will respond without a number (Ex: *5QDT<cr>).
595 595  
596 -Ex: #5UPDATE<cr>
561 +====== __23. Query Model String (**QMS**)__ ======
597 597  
598 -This command sets in motion the equivalent of a long button press when the servo is not powered in order to enter firmware update mode. This is useful should the button be broken or inaccessible. The servo then waits for the CONFIRM command. Any other command received will cause the servo to exit the UPDATE function.
563 +Ex: #5QMS<cr> might return *5QMSLSS-HS1cr>
599 599  
600 -EX: #5UPDATE<cr> followed by #5CONFIRM<cr>
565 +This reply means the servo model is LSS-HS1, meaning a high speed servo, first revision.
601 601  
602 -Since it it not common to have to update firmware, a confirmation command is needed after an UPDATE command is sent. Should any command other than CONFIRM be received by the servo after the firmware command has been received, it will leave the firmware action.
567 +====== __23b. Query Model (**QM**)__ ======
603 603

606 -== Details - Advanced ==
571 +This reply means the servo model is 0xFFF000000 or 100, meaning a high speed servo, first revision.
607 607  
608 -The motion controller used in serial mode is not the same as the motion controller use in RC mode. RC mode is intended to add functionality to what would be considered "normal" RC behavior based on PWM input.
573 +====== __24. Query Serial Number (**QN**)__ ======
609 609  
610 -====== __A1. Angular Stiffness (**AS**)__ ======
575 +Ex: #5QN<cr> might return *5QN~_~_<cr>
611 611  
612 -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.
577 +The number in the response is the servo's serial number which is set and cannot be changed.
613 613  
614 -A positive value of "angular stiffness":
579 +====== __25. Query Firmware (**QF**)__ ======
615 615  
616 -* The more torque will be applied to try to keep the desired position against external input / changes
617 -* The faster the motor will reach its intended travel speed and the motor will decelerate faster and nearer to its target position
581 +Ex: #5QF<cr> might return *5QF11<cr>
618 618  
619 -A negative value on the other hand:
583 +The integer in the reply represents the firmware version with one decimal, in this example being 1.1
620 620  
621 -* Causes a slower acceleration to the travel speed, and a slower deceleration
622 -* Allows the target position to deviate more from its position before additional torque is applied to bring it back
585 +====== __26. Query Status (**Q**)__ ======
623 623  
624 -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.
587 +Ex: #5Q<cr> might return *5Q6<cr>, which indicates the motor is holding a position.
625 625  
626 -Ex: #5AS-2<cr>
589 +|*Value returned|**Status**|**Detailed description**
590 +|ex: *5Q0<cr>|Unknown|LSS is unsure
591 +|ex: *5Q1<cr>|Limp|Motor driving circuit is not powered and horn can be moved freely
592 +|ex: *5Q2<cr>|Free moving|Motor driving circuit is not powered and horn can be moved freely
593 +|ex: *5Q3<cr>|Accelerating|Increasing speed from rest (or previous speeD) towards travel speed
594 +|ex: *5Q4<cr>|Traveling|Moving at a stable speed
595 +|ex: *5Q5<cr>|Decelerating|Decreasing from travel speed towards final position.
596 +|ex: *5Q6<cr>|Holding|Keeping current position
597 +|ex: *5Q7<cr>|Stepping|Special low speed mode to maintain torque
598 +|ex: *5Q8<cr>|Outside limits|{More details coming soon}
599 +|ex: *5Q9<cr>|Stuck|Motor cannot perform request movement at current speed setting
600 +|ex: *5Q10<cr>|Blocked|Similar to stuck, but the motor is at maximum duty and still cannot move (i.e.: stalled)
627 627  
628 -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.
602 +====== __27. Query Voltage (**QV**)__ ======
629 629  
630 -Ex: #5QAS<cr>
604 +Ex: #5QV<cr> might return *5QV11200<cr>
631 631  
632 -Queries the value being used.
606 +The number returned has one decimal, so in the case above, servo with ID 5 has an input voltage of 11.2V (perhaps a three cell LiPo battery).
633 633  
634 -Ex: #5CAS<cr>
608 +====== __28. Query Temperature (**QT**)__ ======
635 635  
636 -Writes the desired angular stiffness value to memory.
610 +Ex: #5QT<cr> might return *5QT564<cr>
637 637  
638 -====== __A2. Angular Holding Stiffness (**AH**)__ ======
612 +The units are in tenths of degrees Celcius, so in the example above, the servo's internal temperature is 56.4 degrees C. To convert from degrees Celcius to degrees Farenheit, multiply by 1.8 and add 32. Therefore 56.4C = 133.52F.
639 639  
640 -The angular holding stiffness determines the servo's ability to hold a desired position under load. 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. Note that when  considering altering a stiffness value, the end effect depends on the mode being tested.
614 +====== __29. Query Current (**QC**)__ ======
641 641  
642 -Ex: #5AH3<cr>
616 +Ex: #5QC<cr> might return *5QC140<cr>
643 643  
644 -This sets the holding stiffness for servo #5 to 3 for that session.
618 +The units are in milliamps, so in the example above, the servo is consuming 140mA, or 0.14A.
645 645  
646 -Query Angular Hold Stiffness (**QAH**)
620 +====== __30. RC Mode (**CRC**)__ ======
647 647  
648 -Ex: #5QAH<cr> might return *5QAH3<cr>
622 +This command puts the servo into RC mode (position or continuous), where it will only respond to RC pulses. Note that because this is the case, the servo will no longer accept serial commands. The servo can be placed back into smart mode by using the button menu.
649 649  
650 -This returns the servo's angular holding stiffness value.
624 +|**Command sent**|**Note**
625 +|ex: #5CRC<cr>|Stay in smart mode.
626 +|ex: #5CRC1<cr>|Change to RC position mode.
627 +|ex: #5CRC2<cr>|Change to RC continuous (wheel) mode.
628 +|ex: #5CRC*<cr>|Where * is any number or value. Stay in smart mode.

632 +====== __31. RESET__ ======
655 655  
656 -This writes the angular holding stiffness of servo #5 to 2 to EEPROM. Note that when  considering altering a stiffness value, the end effect depends on the mode being tested.
634 +Ex: #5RESET<cr> or #5RS<cr>
657 657  
658 -====== __A3: Angular Acceleration (**AA**)__ ======
636 +This command does a "soft reset" (no power cycle required) and reverts all commands to those stored in EEPROM (i.e. configuration commands).
659 659  
660 -The default value for angular acceleration is 100, which is the same as the maximum deceleration. Accepts values of between 1 and 100. Increments of 10 degrees per second squared.
638 +====== __32. DEFAULT & CONFIRM__ ======

662 -Ex: #5AA30<cr>
640 +Ex: #5DEFAULT<cr>
663 663  
664 -Query Angular Acceleration (**QAD**)
642 +This command sets in motion the reset all values to the default values included with the version of the firmware installed on that servo. The servo then waits for the CONFIRM command. Any other command received will cause the servo to exit the DEFAULT function.
665 665  
666 -Ex: #5QA<cr> might return *5QA30<cr>
644 +EX: #5DEFAULT<cr> followed by #5CONFIRM<cr>
667 667  
668 -Configure Angular Acceleration (**CAD**)
646 +Since it it not common to have to restore all configurations, a confirmation command is needed after a firmware command is sent. Should any command other than CONFIRM be received by the servo after the firmware command has been received, it will leave the firmware action.
669 669

652 +Ex: #5UPDATE<cr>
675 675  
676 -Ex: #5AD8<cr>
654 +This command sets in motion the equivalent of a long button press when the servo is not powered in order to enter firmware update mode. This is useful should the button be broken or inaccessible. The servo then waits for the CONFIRM command. Any other command received will cause the servo to exit the UPDATE function.

686 -====== __A5: Motion Control (**EM**)__ ======
687 -
688 -The command EM0 disables use of the motion controller (acceleration, velocity / travel, deceleration). As such, the servo will move at full speed for all motion commands. The command EM1 enables use of the motion controller.
689 -
690 -Note that if the modifiers S or T are used, it is assumed that motion control is desired, and for that command, EM1 will be used.

692 -====== __A6. Configure LED Blinking (**CLB**)__ ======
693 -
694 -This command allows you to control when the RGB LED will blink the user set color (see [[16. RGB LED>>||anchor="H16.RGBLED28LED29"]] 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:

709 -Ex: #5CLB0<cr> to turn off all blinking (LED always solid)
710 -Ex: #5CLB1<cr> only blink when limp (1)
711 -Ex: #5CLB2<cr> only blink when holding (2)
712 -Ex: #5CLB12<cr> only blink when accel or decel (accel 4 + decel 8 = 12)
713 -Ex: #5CLB48<cr> only blink when free or travel (free 16 + travel 32 = 48)
