I was just curious what type of errors you got. I have mine hooked up with only two slaves and so far everything is working fine. I did use twisted pair unshielded wires between the slaves and master though. I was also curious if you ever tried the "count" function prior to your series of ...

Peter, When you put your BMS in your car what portions of the software did not work properly due to the EMI issues? I was just curious if everything had errors or just one portion. I would assume most of the problem was the signal being transmitted from the slaves to the master causing erroneous cel...

Yes, adding the comment to lines that I modify is a very good idea.

Thanks for pointing out the possible overflow on SocCounter. I will keep an eye on it.

Since I can not view the latest vsm files, could you send them to me as jpeg?

Peter, Thanks for your help. Your solution fixed the problem. The mistake that I made was that I changed the line of code that was originally "symbol Baud2400 =T1200" to "symbol Baud2400 =N1200". I did this because instead of the display that you are using I was using a typical 1...

I inserted what you suggested into the slave code (b0=200). For some strange reason when the master retrieves this information, it displays 188. I tried copying the code into this reply but it looks very messy. What is the best method to copy the code and keeps its format? [/list][/code][/quote]

Peter,

Thanks for the information. I will try what you suggested when I get back in town. I will let you know how it turns out.

Can you tell me what the width and heigth of the display is? How much do you want for it? I am curious to know if the software that you sent me is the code that you had working properly on the bench. I am getting some strange results. When I first ran it, it was displaying that my cell was less than...

Greg, I would recommend getting the HAAS 300 instead of the 500. Both the 300 and the 500 can measure up to a peak of +/-900 amps. However, the 300 gives better resolution (300 amps = .625 volts vs 500 amps = .625 volts). When I spoke with the tech rep he said the only real reason to use the 500 is ...

Never mind about how we calculate cell voltage. I remembered a link that you had referenced before (http://www.picaxeforum.co.uk/showthread.php?t=8624) that describes how it works.

I know, I updated the code to work with the 16x2 LCD. I saw that display before. I believe it is only a 480 x 234 resolution. My biggest concern with this display was the curved front surface which will not mount in my application very well. I have a question about how you are sensing the battery vo...
