Hwang Xian Shen, Puddleby-on-the-Marsh. Must I go with a micro-P capable of working 16bit wide bus? Still, I was wondering what is preventing the stamp from communicating effectively with the motor controller.

LM from Texas Instruments

Since the Propeller chip is competatively priced with the BasicStamps, it may be a better fit. If there are disturbances to the motion. Not having worked with the device LMI can’t make specific recommendations, but it ought to work with a Stamp. Quick Links Categories Recent Discussions.

Right now, I am trying to comprend how the video juggles memory with something referred to as tiles. That’s the reason why I insist on sticking with LM I agree with Bruce that this is not the best device to use with a Stamp because of the number of pins required.

If the motor is unable to maintain the. You can either build a 16bit wide output with two bytes or go with a 16bit or 32bit processor. Thanks for the reply.


Will there be a problem. At any time during the. So those unused bits would be ignored. All things considered, I can live and thrive without Microsoft products. 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. But, it is not as precise a controller as the LM I am in Taiwan too.

If I were to connect a datxsheet clock and power up, then the return status byte would be FF.

Ml629, it appears that not all of the 16bits are used. Or during the micro-P selection, I have to go with one based on a 16bit core. The whole uP can only withstand ma at one time. I know there is too many questions here.

It can be done, but twice as slow at the same clock speed. If the motor is unable to maintain the specified velocity which could be caused by a locked rotor, 9 www. Use a single power supply of 32V, 1A which splits to two set of power and ground lines. How datwsheet I identify if the IC is burnt or not? 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 final adtasheet.


So, a clock is necessary for LM to function.

Will consider this as one of the option if the learning curve is not that steep and development time is short. When operating in the velocity mode, the motor accelerates to the specified velocity at the specified acceleration rate and maintains the specified velocity until commanded to stop. SPIN is not that difficult.

The velocity is maintained by advancing the desired position. You certainly will have more speed. LM is still giving a response, just not the one I expect.

After connecting all the parts, I powered on the system. The trapezoidal velocity profile generator computes the de. It is the same problem as the BasicStamp2px. Sometimes, it jump to maybe hex00 or hex It is really fustrating to be working on something for a few weeks and then find that it does not work out. It is only providing a brige ciruit like a LMD, but no motion control in place.
