I'm definitely interested - have you got a spare I can buy?

They don't seem to do a 200A version though; not sure if I need it but I bought the 200A bidirectional sensor. Due to an oversight, 2 of them in fact...

My C rewrite gathers more pace, I now have interrupt-driven comms for the display and the slaves, using the on-board UART. It took me a while to realise that the PBP serout and serin commands are mostly using inverted signals (which caused me a few headaches!). Because of this I've had to invert the...

I would be quite happy to fill in your questionnaire but it appears to be aimed specifically at electric car ownership and use. Would it not be better worded as "electric vehicle", as otherwise this rules out owners of electric motorcycles?

I'm building my pack from the 38140S variant on that, ordered from Evassemble. I understand Evassemble don't have a great reputation in the BMS stakes, but 50off cells cost me just over £700 including shipping - they would have cost over £925 from those people! Still, at least I now know where to ge...

Ok, say you get "10,20,30,40,50,60,70,80" for one sensor and "80,70,60,50,40,30,20,10" for the second one; change the lines: owout DigitalTemp,1,[$55,$28,$B9,$11,$16,$01,$00,$00,$A4,$BE] and owout DigitalTemp,1,[$55,$28,$CD,$11,$EA,$00,$00,$00,$28,$44] under "if TempInc = 0&...

Hi Martin, maybe I can help with the temp sensors. The $44 lines are the "start conversion" operation and $BE = "read scratchpad" (in this case the temp reading). You just need to make sure that the values you put in after "if TempInc = 0 then 'Read 1st sensor and start 2nd ...

Ah no, as you were :) It's an ICD2-specific thing I think - from the help file: "When Internal MCLR is used with MPLAB ICD 2 for programming, both Vpp and Vdd are powered together, and then Vpp is pulled high to Vihh to enter programming mode. This means that your code will be running before Vp...

I'm actually a bit confused about how it programmed in the first place. When I tried to reprogram it yesterday with those settings it gave me the warning then failed to program. Before, I just got the warning and programming succeeded - I'm just wondering whether I programmed it as a slave the first...

I'm using an ICD2 driven by MPLAB. I don't know whether it reads the configuration bits from the hex file, but I had "configuration bits set in software" checked and I kept getting that warning. Unchecking that box and setting the MCLR manually fixed the problem.
