Peter, could you please explain why this is the case.. I would like to understand.

Thanks

Re: Old BMS Hardware Thread

I would like to create the 26 cell slave board and have a pcb service create the board for me..
These pcb services need extended gerber files, are these available on the board? Can't seem to find them.

Or the files of the pcb software used, so I can create my own?

Thanks

Re: Old BMS Software Thread

Figured it out.. the slaveboard is now responding to command's from the netduino.

See here the slave board responding to command '1', and resending it to the next slave:

The trick was (as I suspected) the inverted signal

Re: Old BMS Software Thread

Me too. I guess it has something to do with the inverted signal. I ordered myself one of these: http://www.saleae.com/logic/ to find out.. :D My goal is to connect the slaveboard to a netduino plus (with networking and SD card) and host a webserver on it displaying all sorts of info... and keep the ...

Re: Old BMS Software Thread

That's it.. So for the record, when using the Picbasic Pro compiler (2.60a) with the MPASM assembler you have to: 1. Comment out the DEVICE statements: '@ DEVICE PIC12F683,MCLR_OFF '@ DEVICE PIC12F683,BOD_OFF '@ DEVICE PIC12F683,PROTECT_OFF '@ DEVICE PIC12F683,WDT_OFF 2. Add the following line: 'Bel...

Re: Old BMS Software Thread

Greg,

You must be referring to this:
So if you are going to compile from the source code you need to comment out the __config line in your pbp 12F683.INC file.


Will try this when I get home, thanks.

Re: Old BMS Software Thread

Peter, Thanks.. I also tried this based on documentation but didn't get it to compile. With your MPASM version I still get a compile error: ERROR: Unable to execute mpasmwin.Error[118] C:\PBP\SAMPLES\BLINK.ASM 178 : Overwriting previous address contents (2007) If I comment out the __config line, it ...

Re: Old BMS Software Thread

Hmmm.. can't get the PM assembler to work on my 64bits system, guess that's not supported.
Will de slaves not work with the MPASM assembler?
