As accurate as our one second timer and the maths associated with the code. My mph is within 1mph of my oem speedometer. Odometer is within 10%. WH mile is all over the place
I hate that part of the code and am highly tempted to scrap and remove it. I'm not clever enough with the maths
It could be greatly improved no doubt.
Any sort of BMS alarm or pressing of the menu button immediately screws up the calculations anyway if the one second loop is interupted/delayed.
Have ago at your
watchdog idea if you want of course.
Been playing with a simple opto controlling the voltage of another modifed charger today, driving the opto led via 5k pot 3v battery. Works well adjusting output voltage up and down. But needs HPWM facility if we are to implement it on the Master, which I don't believe we have sadly on the charger control opto ouput pin
Something else for V3 careful choice of pic pins. I'll check this.
I intend to spend a bit of time now getting the remote display and data dumping to a PC sorted. The remote display will not support data dumping in future, it uses too much code space. it will be a simple visual indication / alarm.
Dumping BMS data will be/is done by the redundant master programming port and picaxe usb lead direct into an excel speadsheet. This allows much higher comms speed for a start.
I haven't tested any of the dumping/remote code since we moved to pbpro!!
