Quick Links Categories Recent Discussions. Can anyone advise how to do it? Or do I need interfacing components?

I thought the clock is used mostly by the encoder. Comments 13 Comments sorted by Date Added Votes. The user guide was not very clear with the interfacing. I’ve always had good luck with motor controllers like the L, but you’ve not been all that specific about your exact needs.

Many successful projects have used the L datsaheet similar motor control chips. I have attached a copy of the LD chip for your inspection. Not having worked with the device LMI can’t make specific recommendations, but it ought to work with a Stamp.

The signals are straightforward, should be Stamp compatible. I agree with Bruce that this is not the best device to use with a Stamp because of the number of pins required. As shown by the status, it is staying at hex Sometimes, it jump to maybe hex00 or hex I was thinking datadheet the RST is an asychronous input and so might not need a clock as long as I pause long enough, correct me if I am wrong in this line of thought.

If I were to connect a 8Mhz clock and power up, then the return status byte would be FF. Since the Propeller chip is competatively priced with the BasicStamps, it may be a better ln629. You certainly will have more speed. Hwang Xian Shen, Puddleby-on-the-Marsh. All things considered, I can live and thrive without Microsoft products. LINUX is just fine. The propeller sure look powerful but is the coding difficult? Will consider this as one of the option if the learning curve is not that steep datashset development time is short.

Still, I was wondering what lmm629 preventing the stamp from communicating effectively with the motor controller. Tried various means and dqtasheet different clocks circuits, still doesn’t seems to work dataeheet. How could I better troubleshoot the problem?

SPIN is not that difficult. As long as you don’t ‘fall in love’ with video processing, things would be quite similar to programming in PBasic. That is where you might lm692 a steep learning curve. Right now, I am trying to comprend how the video juggles memory with something referred to as tiles. I am sure it will be a rewarding addition.

Design Requirement for my part. Must I go with a micro-P capable of working 16bit wide bus? Or during the micro-P selection, I have to go with one based on a 16bit core.

LM from Texas Instruments

Internet is down due to Taiwan Earthquake!!! Did I caused something to locked up along the process. Checked on the 8Mhz clock on the oscilloscope and it gives a pretty nice clocking, no problem with clock. Will there datahseet a problem. I know there is too many questions here. Please bear with me and help me solve the problem. I am in Taiwan too. I cannot answer all your questions, but here are some answers. Yes, it appears that not all of the 16bits are used.

My count is 13 total. So those unused bits would be ignored. You can either build a 16bit wide output with two bytes or go with a 16bit or 32bit processor. While the SXes will tolerate 30ma, less is better. The whole uP can only withstand ma datasheeg one time. So you get more speed and simpler code. The Propeller is a 3. It will tolerate 5.

Interfacing problem with Basic Stamp BS2px24 and LM629

It can be done, but twice as slow at the same clock speed. It is the same problem as the BasicStamp2px. And in some cases, you might need a 16bit latch to get the timing right. But, it is not as precise a controller as the LM Thanks for the reply. 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.

And this is probably the reason why I can’t seems to get the thing working?

The speed is most likely not matching. I suspect I actually cooked the LM, but no smell and sign of being cooked. How do I identify if the IC is burnt or not? LM is still giving a response, just not the one I expect. Did I really kill the IC, or did I not? I’m not in Taiwan, but the internet access here is greatly affected in some way. A lot of website simply timeout or inaccessible. Heard that 6 of the 8 fiber optic underwater channels were damaged.

Nature is really messing things up this time.

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. It is only providing a brige ciruit like a LMD, but no motion control in place. That’s the reason why I insist on sticking with LM It is really fustrating to be working on something for a few weeks and then find that it does not work out.

The previous LM seems dead. Changed to a new LM and added a clock of 8MHz. So, a clock is necessary for LM to function.

My advise to anyone: Dstasheet a Logic Analyser to understand the actual timing, then adjust the timing through tweaking the PBasic coding in the basic stamp. It is crazy to depend only on oscilloscope and try to imagine what is actually happening.

I had spent months on it by now.

datasheeet Use a single power supply of dafasheet, 1A which splits to two set of power and ground lines. On one set, drop the voltage to 5V through 2 stages of voltage regulators 24V, then 5V. On the other set, drop the voltage dafasheet 24V with one voltage regulators. This one supplies to the LMD After connecting all the parts, I powered on the system. Initially seems a little ok,but after a couple of runs the nightmare seems to reappear. What is wrong here? Did I killed LM because I connected a motor and power up?

Can someone explain what are the possibilities and the reason that explains why after connecting a motor, LM can get killed instead? Should I use two separate power supply for powering ICs and motor? Was it some back EMF issue here? Sign In or Register to comment.
