Re: Regression with 4.2.1 FW?
Well, with no feedback received, I implemented a workaround. When I send a batch of buffered commands, the first command is unbuffered to clear out any remaining commands executing on the motor. Then I write my buffered commands to the RC and then immediately check the command buffer to make sure it...

Regression with 4.2.1 FW?
I'm using a RC 2x7A. Since updating to the 4.2x the I'm seeing different behavior with the same stable code that works on 4.1x versions. I'm moving a telescope so I do two buffered moves for each position. When I check the command buffer I can see the value changes from 0x80 to 0x01 which means two ...

Re: Is thee a way to do a buffered velocity/speed command?
OK, figured out a workaround. I just need to add a second buffered speed position move with the desired velocity and set the position *way* out there, so it's effectively never completes. Then I can change to non-buffered speed command in a leisurely fashion. Or perhaps, not at all.

Is thee a way to do a buffered velocity/speed command?
hi-- I'm attempting to use a RC 2x7a to control the position of a telescope. What I'm trying to do is a position move on both motors and I don't really care with motor finishes first. One of the axis need begin a velocity move at a low speed for the telescope to track the object in the sky. I can us...

Re: Starting thread for user manual updates / corrections
Found one more on page 70, QPSS should be QPPS 70 - Set Motor1 Default Speed Set M1 default speed for use with M1 position command and RC or analog modes when position control is enabled. This sets the percentage of the maximum speed set by QPSS as the default speed. The range is 0 to 32767. Send: [...

Thanks! I'll be used the packet serial model, so should be good to go.

Starting thread for user manual updates / corrections
Hi-- Basic Micro has some truly innovative products at solid price point. We linux folks typically have to tweak/write code to get our desired functionality, which causes us to read the documentation. Usually cover to cover. :) I found a couple corrections and thought by starting a thread, we could ...

Re: Is there an error in docs on "Read Status" cmd 90?
Understood. It looks like the first set of messages are masked to 3 bytes and the last two are masked to 4 bytes. What is the correct length of the response message now? Thanks, Ron From Page 73 of the User Manual Normal 0x000000 E-Stop 0x000001 Temperature Error 0x000002 Temperature 2 Error 0x00000...

Is there an error in docs on "Read Status" cmd 90?
Hi-- i'm trying to implement a c function to read the status of the RC, but i'm confused by the docs, snippit is pasted below. If you look at the receive field, "Status" is defined as one byte, but the mask to decode is a 16bit word. Which is correct or am I missing something? Thanks, Ron ...

Newbie - question on default values for speed & accel
Hi-- I'm new to the roboclaw and most of my experience with servos is using custom LM628/629 HW. I trying to understand how the RC works. In the LM628 world, I would program a single max acceleration values (same value for both accel and decel) and set a max speed along with the PID settings. Once t...
