Does Anyone Have A Cytron Smartdrive Duo 30 And What Are The Diffrences?

Does anyone have a Cytron Smartdrive Duo 30 and what are the diffrences with a sabertooth in settings?

https://www.cytron.io/p-30amp-7v-35v-smartdrive-dc-motor-driver-2-channels

Folowing the manual and comparing it... I came to these settings... Still have to test it... But maybe someone has some conformation?:) 


# Stop
SendSerial(D0,9600,0)
SendSerial(D0,9600,128)


# Forward
# Motor 1, 63 is full speed forward.
SendSerial(D0,9600,63)
# Motor 2, 191 is full speed forward.
SendSerial(D0,9600,191)


# Differential Turn Right
# Motor 1
SendSerial(D0,9600,63)
# Motor 2
SendSerial(D0,9600,255)


# Differential Turn Left
# Motor 1
SendSerial(D0,9600,127)
# Motor 2
SendSerial(D0,9600,191)


# Reverse
# Motor 1, 127 is full speed reverse.
SendSerial(D0,9600,127)
# Motor 2, 255 full speed reverse.
SendSerial(D0,9600,255)

And what about the Speed Changed setting?

The commands look right - but you'd have to test.

If you want speed control, there's two ways to go about it

1) Create a skill control 

2) Use a custom movement panel

If you choose #2, there's a $speedleft and $speedright variable which you can use. You'd have to use a little math to determine the speed for each direction.

It has been a long time, but i am back on this project;)

So i have made a custom movement panel.
Everything works...  But it's just one speed...  
i managed to found out if i set lower numbers in the script the speed will be lower...  But the 2 shuffles for speed won't work.

Would be nice if the sabertooth script was editable or viewable so i can compare;) 

I found Gwen's question... about "ramping" As i understood this was to build up te speed instead of only 1 speed that stops abrubtly (https://synthiam.com/Community/Questions/Movement-Scripting-Help-Please-2983)

I loaded the latest script and changed some perimeters to be compatible with this controller. But it doesn't seem to work for me...

I think my problem is... 
Where the sabertooth increases the speed from a stop. 0-10-9-8-7-6-4-3-2-1-0-1-2-3-4-5-6-7-8-9-10
The Smartdrive Duo increases otherwise 0-1-2-3-4-5-6-7-8-9-10-0-1-2-3-4-5-6-7-8-9-1-0

Thanks for the fast response:)
I was reallly mindboggling about what to do. 

Going to try that and let you know my results. But if i look at the manual that should do the trick:) THANKS!

They did all the planning for you ahead of time it seems. It makes most sense to re-use the continuous rotation Movement Panel since it's created for this use-case...

It works! THANKS!
I only need to adjust the speeds and sensitivity, but how that works i allready know;)

Is driving with the RC option also possible in autonomous mode? 
And what is the diffrence exactly between Simplified Serial and RC mode for robotics? I thought i really needed Simplified Serial... (because everyone goes for that with sabertooth in the R2D2 world)   I am trying to understand that part;)

Ok, good enough for me;) Thanks for your guidence;)
