P - Just checked your Master jpg and compared it with mine for components and (Doh!) I see I put in R26, R18, C11, C7 AND C9. I gather R18 just alters the screen brightness (I suspect with my current set up - using the USB video adaptor - this wont affect things much). I'll take out the others and s...

Peter, Hi - tried the 2 new hex files - I can't get the cell number changes to stick - they always get reverted to 50... How do you know if you have 'super slave' mode on or off? Do you find your buttons are a bit tetchy? Slecting one option sometimes triggers a second unwanted one? I do - and I fou...

Peter et al, Re connecting the Master to a PC for data-logging/alternative display/internet access/SMS-ing/GPS etc etc I found this on eBay just now. http://cgi.ebay.co.uk/USB-TTL-Serial-Cable-/290445149419?cmd=ViewItem&pt=UK_Computing_CablesConnectors_RL&hash=item439fe144eb#ht_738wt_987" on...

Peter, I only found the new BMS forum thread last night at... viewforum.php?f=53. I had been relying on my old links. Now it's all a lot more digestible. MW

Hi Peter, Re-programmed master, watchdog and slaves with the 3 diferent programs you gave me above and all that happens after 2 mins is alarm piezo comes on and yellow dash LED lights - watchdog error? None of the buttons work and even the display doesn't give a splash screen - just goes straight to...

Peter, Thanks for clearing that up. Yes, the combined simulated 1 cell voltage is 3.9V so that is why the load resistor is coming on I guess. I have changed the master.txt file to cope with the one slave I currently have connected for testing as follows: symbol Cells = 1 symbol MaxPackVoltage = 4500...

Peter, Can you advise me what version of software I should be using for the Master (picaxe), slave (pic) and watchdog (pic)? I am getting very lost! Or should I give up on the picaxe master IC and go pic? If so, can I use the picaxe chip (I gather it is non reversable conversion if I do?) Tried the ...

Peter, An update... I have put together a dash pcb for the leds and switches and connected these to the Master pcb. I am waiting on IC2 ICs but in the meantime have now wired in 2 x LM335's for an1 & 2 and these, with the master board, appear to be working (implying everything else on the master...

Cell layout attached (again - I didn't notice the file over-size limit warning).... MW

Hi Peter, Thanks for that - I can see I should be able to figure out what the dash buttons and LEDs do exactly from the Master txt file. Pic of my cell layout attached... I have updated the BMMS page on my site - still needs some re-jigging for clarity and I'll add programming and alert descriptions...
