Interfacing problem with Basic Stamp BS2px24 and LM — Parallax Forums

When operating in the velocity mode, the motor accelerates to the specified velocity datasheef the specified acceleration rate and maintains the specified velocity until commanded to stop.

After connecting all the parts, I powered on the system.

The LM uses this infor. In the position mode. Not having worked with the device LMI can’t make specific recommendations, but it ought to work with a Stamp. Use a Logic Analyser to understand the actual timing, then adjust the ln629 through tweaking the PBasic coding in the basic stamp.


This one supplies to the LMD Design Requirement for my part. Figure 10 illustrates two typical trapezoidal ve- locity profiles. It is the same problem as the BasicStamp2px.

I have attached a copy of the LD chip for your inspection. Home – IC Supply – Link.

How could I better troubleshoot the problem? I suspect I actually cooked the LM, but no smell and sign of being cooked. Quick Links Categories Recent Discussions.

It will tolerate 5. Right now, I am trying to comprend how the video juggles memory with something referred to as tiles. Will there be a problem.

I agree with Bruce that this is not the best device to use with lm6629 Stamp because of the number of pins required. Tried various means and even different clocks circuits, still doesn’t seems datasheef work out.

In the position mode of operation, the host processor specifies acceleration, maxi- mum velocity, and final position. That is where you might find a steep learning curve. Or during the micro-P selection, I have to go with one based on a 16bit core. Can someone explain what are the possibilities and the reason that explains why after connecting a motor, LM can get killed instead? While the SXes will tolerate 30ma, less is better.


Precision Motion Controller

Internet is down due to Taiwan Earthquake!!! Thanks for the reply. If there are disturbances to the motion during velocity mode operation, the long-time average veloc- ity remains constant. Please bear with me and help me solve the problem.

My advise to anyone: If the motor is unable to maintain the. The trapezoidal velocity profile generator computes the de. You certainly will have more speed.

On the other set, drop the voltage to 24V with one voltage regulators. Can anyone advise how to do it? On one set, drop the voltage to 5V through 2 stages of voltage regulators 24V, then 5V.
