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. Did I killed LM because I connected a motor and power up? Did I really kill the IC, or did I not? Since the Propeller chip is competatively priced with the BasicStamps, it may be a better fit. And in some cases, you might need a 16bit latch to get the timing right.

Not having worked with the device LMI can’t make specific recommendations, but it ought to work with a Stamp. The previous LM seems dead. I managed to find a pc with a faster internet access not through the phone line and looked at the datasheet for L It does not seems to be the one I need. And this is probably the reason why I can’t seems to get the thing working?

Comments 13 Comments sorted by Date Added Votes. SPIN is not that difficult. Still, I was wondering what is preventing the stamp from communicating effectively with the motor controller.


Can anyone advise how to do it? At any time during the.

As shown by the status, it is staying at hex The propeller sure look om629 but is the coding difficult? Design Requirement for my part.

Right now, I am trying to comprend how the video juggles memory with something referred to as tiles. A lot of website datasheeet timeout or inaccessible.

If there are disturbances to the motion during velocity mode operation, the long-time average veloc- ity remains constant. Can someone explain what are the possibilities and the reason that explains why after connecting a motor, LM can get killed instead?

The velocity is maintained by advancing the desired position. LINUX is just fine. Use a Logic Analyser to understand the actual timing, then lj629 the timing through tweaking the PBasic coding in the basic stamp. I agree with Bruce that this is not the best device to use with a Stamp because datahseet the number of pins required.

On the other set, drop the voltage to 24V with one voltage regulators. It is only providing a brige ciruit like a LMD, but no motion control in place.

I thought the clock is used mostly by the encoder. That is where you might find a steep learning curve.

Yes, it appears that not all of the 16bits are used. Hwang Xian Shen, Puddleby-on-the-Marsh. Checked on the 8Mhz clock on the oscilloscope and it gives a pretty nice clocking, no problem with clock.


Many successful projects have used the L and similar motor control chips. If the motor is unable to maintain the. So those unused bits would be ignored. I have attached a copy of the LD chip for your inspection.

I suspect I actually cooked lk629 LM, but no smell and sign of being vatasheet.

This one supplies to the LMD Must I go with a micro-P capable of working 16bit wide bus? Home – IC Supply – Link. When operating in dstasheet velocity mode, the motor accelerates to the specified velocity at the specified acceleration rate and maintains the specified velocity until commanded to stop. Thanks for the reply.

Interfacing problem with Basic Stamp BS2px24 and LM629

While the SXes will tolerate 30ma, less is better. The user guide was not very clear with the interfacing. Internet is down due to Taiwan Earthquake!!! So, a clock is necessary for LM to function. The LM uses this infor- mation to affect the move by accelerating as specified until the maximum velocity is reached or until deceleration must begin to stop at the specified datazheet position.

I cannot answer pm629 your questions, but here are some answers. The whole uP can only withstand ma at one time.
