Peter, Yes, I got the display working fine. Your calcs for IR seem correct to me also. I have the basics of the system working now. That is the slave boards are working well with the master (V1.0) and I have adjusted the code to work with a LEM current sensor. I am currently working on getting the w...

Peter, I think logging the cell data is a great idea. I have seen another system that does this and the most interesting thing I have found is how each cell compares to the others at the same moment in time. Under hard accelerations you could quickly see the voltage difference between your best and ...

Peter, I am going to drive the transmitter using the version 1.0 master board (I haven't had time to assemble the V2.0 yet). I remember you connected it via the drive inhibit connecctor. I assume you simply supplied 5 volts to pin1 of the J6 connector and pin 2 was connected to the data in pin on th...

Peter, I am starting to work on the remote data system. I saw a picture you previously posted of the transmitter http://www.solarvan.co.uk/bms/RemoteDisplay002.jpg It shows a resistor and a capacitor but I have not been able to find any reference schmatic for the transmitter. Did I miss it somewhere...

Peter,

I received the parts today.....Thanks..

On the display, I know the coax is for vido in, I assume the red and black wires are for 12 vdc. What are the two small orange wires (about 3" long) that are joined to a small connector for? Do you have any tech data on this display?

Peter, I am using your slave software. My initial problem with running your software for the slaves had to do with the setting of the configuration bits that you do in the begining of the software. I typically set my configuration bits using a config window during compiling. The code you wrote for t...

Well I finally found the time to assemble one of my 12 channel multi-slave boards. It is running with conventional pic chips. So far everything seems to be working well on the bench. I am looking forward to connecting it to a 3-1/2" display so I can see all of the data.

Peter, Glad to hear things are going well with the multi-slave boards. I installed your software into a normal pic on one of my slaves but yet I still get the same results "cell error". I don't understand it as it still works correctly with a picaxe. I guess something other than the code i...

Peter, Great job. I haven't had a chance to look at your code to see what the difference is. Do you have any ideas what I was doing wrong? Have you run across your 3-1/2" LCD display that doesn't have a housing? I am hoping to find some time to work on this over the Christmas holiday. I am also...

I wanted to provide some background on the code that I wrote for using a standard PIC on the slave portion. I have some of Peter's slave boards and one of his master boards. I was able to get this configuration working just fine using the original picaxe chips on both boards. What I wanted to do was...
