PakTrakr battery monitor

I have a 2 channel 16 bit differential input tc3401 which has +- for both channels

hmm, that looks like a nice lil chip! i guess you would need 3 of them?? hook it up to batteries and see if it lets the smoke out!

i have a mcp3002 here i was planning on trying as a SOC ADC. i got it because of the differential inputs. i've been using atmel µCs w/o lower vref setting capability and have had a difficult time configuring/tuning a rail to rail opamp for differential inputs. if i would just switch to PIC i wouldn't have this problem as the lower vref can be set in software.

that 16bit delta-sigma would also solve my lower vref dilemma; just throw more bits at the problem!

Yea you can always through more bits at it but then you have to do the math !!!

I am currently reading the voltage out of my carts curtis controller what could be better than that. using the programming port!!
next step is sensor data, motor current on and on.

reworking the math is a lot easier than tuning analog!

thats cool! does the curtis output current as well? can you keep the connection alive while operating the controller? are you parsing the data to a laptop? lcd? 7 seg? a in-dash on-the-fly programmer/monitor would be sweet!

Okay slow down big boy!!! I haven't gotten that far yet! but my answer is yes . at this time I'm using a basic stamp for prototype then I will port it to a pic chip using a 2 or 4 line lcd if I really want to get fancy I will use a graphic lcd.
I haven't had a lot of time to work on it the last week for some reason the wife wants her 30,000 dollar car in the garage and not my cart well I guess you see who wears the pants in my family.

don't be making fun of my illness Im doing the best I can
one thing for sure I don't drive an EZGO

Now that there is funny
