It is only providing a brige ciruit like a LMD, datasehet no motion control in place. LM is still giving a response, just not the one I expect.

Please bear with me and help me solve the problem. A lot of website simply timeout or inaccessible. Did I really kill the IC, or did I not?

Precision Motion Controller

Can someone explain what are the possibilities and the reason that explains why after connecting a motor, LM can get killed instead? Since the Propeller chip is competatively priced with the BasicStamps, it may be a better fit.

It is the same problem as the BasicStamp2px. Or during the micro-P selection, I have to go with one based on a 16bit core. I suspect I actually cooked the LM, but no smell and darasheet of being cooked. While the SXes will tolerate 30ma, less is better.


I know there is too many questions here. Figure 10 a shows a simple trapezoid, while Figure 10 b is an example of what lm269 trajectory looks like when velocity and position are changed at different times during the move.

My advise to anyone: After connecting datashdet the parts, I powered on the system. Design Requirement for my part. I am in Taiwan too. Internet is down due to Taiwan Earthquake!!! So the reason you are trying to recommend 32bit Propeller over 8-bit Stamp is because with 8-bit Stamp, it is not fast enough to be compatible with the faster LM that work better with bit micro-P.

That’s the om629 why I insist on sticking with LM Must I go with a micro-P capable of working 16bit wide bus? So those unused bits would be ignored. It will tolerate 5. Thanks for the reply. Yes, it appears that not all of the 16bits are used. The whole uP can only withstand ma at one time. All things considered, I can live and thrive without Microsoft products.

And this is probably the reason why I can’t seems to get the thing working? So, a clock is necessary for LM to function. I managed to find a pc with a faster internet access not through the phone line and looked at the datasheet for L The velocity is maintained by advancing the desired position at a constant datasgeet.


This one supplies to the LMD In ddatasheet position mode of operation, the host processor specifies acceleration, maxi- mum velocity, and final position. Not having worked with the device LMI can’t make specific recommendations, but it ought to work with a Stamp. Still, I was wondering what is preventing the stamp from communicating effectively with the motor controller.

Was it some back EMF issue here? Hwang Xian Shen, Puddleby-on-the-Marsh. In the position mode. Home – IC Supply – Link. But, it is not as precise a controller as the LM As long as you don’t ‘fall in love’ with video processing, things would be quite similar to programming in PBasic.

Figure 10 illustrates two typical trapezoidal ve- locity profiles. And in some cases, you might need a 16bit latch to get the timing right.
