Stuart Longland	39ef58f145	doc: Add re-design documentation. ... After some thought, the original code isn't going to do what is needed. The following image is a re-design of the firmware having re-assessed the requirements.	2017-03-11 23:29:57 +10:00
Stuart Longland	301c9a9d43	Lengthen some timeouts. ... We seem to be a bit too impatient waiting for the mains charger to kick in, and too hasty for the fan.	2016-11-05 17:04:45 +10:00
Stuart Longland	d29d15308b	Add shutdown delay on "high" threshold. ... We should delay our shutdown in case the charger decides to ramp down itself. Otherwise we can get the situation where a smart charger starts high, tripping the high threshold immediately, leading to the controller and charger oscillating between on and off.	2016-11-05 17:04:05 +10:00
Stuart Longland	d91ec8d786	Move setpoint definitions to separate header. ... This will get copied over to setpoints.h, where the developer can customise them. If they do so, and I have to change things, the Makefile will warn them of this.	2016-09-04 06:57:36 +10:00
Stuart Longland	772d5b9d30	FAN control: Fine-tune minimum PWM ... It appears the minimum PWM is more strongly dependent on battery voltage than I had planned, it needs to be just a little higher to ensure the fan keeps turning at low RPM.	2016-09-04 06:47:28 +10:00
Stuart Longland	e62cbf497a	fan PWM tweaks. ... - Adjust the calculations so that we base our initial PWM at 0 then clamp to minimum PWM - Implement a fan kick-start mode - Start with fan off so kick-start mode works	2016-09-04 06:30:52 +10:00
