pilminder 14m2 dual mains_plugpack operation 17-12-2011 solved item F.bas

'TIMING TEST RESULTS

'26/9/2011
'8 hr test resulted in 8hrs 2 seconds duration using modified interupt routine on mains operation
'1 hr test perfect again using mains interupt ! Allowed led to flash for 3 mins before taking med, hence a 1 hr 3 min time as expected.
'27/9/2011
'12 hr test in progress using pilminder 08m2 plugpack operation 27-9-2011 solved bug 3.bas on mains operation
'- tripped at 12hrs exactly. Allowed it to flash for a while before allowing test to continue to 24 hr point
'- where it tripped on shedule again!
'28/0/2011
'using code pilminder 08m2 plugpack operation 28-9-2011 working on item D.bas
'started 8 hr test (3 pips) running off internal timer - light flashed 8 hrs 34 secs later
'/29/9/2011
'started 1 hr test using code pilminder 08m2 plugpack operation 28-9-2011 working on item D.bas 
'- internal timer 59 min 58 secs allowed led to wink 2 mins, thenacknoledged it

'- 3rd time 59 mins 50 secs
'4th time on mians - 59 mins and about 30 secs
'5th time on mains timing = 59 mins! I suspect it is not returning to mains timing at all!
'6/10
'series of 3 or 4 1 hr tests, on both mains and batt timing , also checked switching between timing sources. No fault found
'7/10
;12 hr test on batt timing - within30 secs. swapped to and from to mains, no problems. 12 hr test on mains continues....
;declaring bug 7 not found - cant fix what aint broke! might be related to debug...
;declaring development D done. 
'13/10
;declaring development E done. 
;started a 8 hr test on mains
;8hr bit was fine, but it didnt do the beepy thing 30 mins later. it wasnt doing anything....
;likely to be sun onto the IR sensor..
'made new sensor hood suitable for daytime use, started 3 hr test. started flashing exactly on time. 30 mins & 30 sec timers worked ok as well.



'BUGLIST

'*1* done - Reminder LED flashes inconsistently
'*2* done Reminder beep for bottle not back in holder is inconsistent as well
'*3* done Late med interval timer to add a beep if user not taken pill doesnt work
'*4* fault not found I THINK the bottle may be being tested as being present all the time - this will reduce battery endurance if thats the case 
'*5* fault not found Exec loop is being stopped in a 1:30 duty cycle by Check_Med_Time - at least when debug in execloop it is...
'*6* Shouldnt the return in the interupt be right @ the end of the function????
'*7* fault not found later - related to bug 10? changeover from mains to internal timer, sometimes dumps sec and min timers - single pip might be a clue
'*8" reminder beep to put bottle back not working on repeating 1 hr timer (was on internal timer on this test) . it buzes when time expired
'	it does work when on the mains timer! needs a retest
'*9* the user has to put the bottle back for the 30 sec timer at begining to work. It all stalls if you leave it out
'*10* changeoevr from mains<>battery very flaky. often reboots i think its hardware not software - psu rail glitch i suspect
'*11* done beeping to get user to put bottle back only lasts 3 min 50 sec, and side_led is left on when it stops. byte counter overflowing...
	
'IDEAS FOR DEVELOPMENT

'**A** done - User should be prompted to take 1st dose of meds as soon as programming complete
'**B** done Can have test/demo mode where everything happens quicky - test if bottle present on start or not *****
'**C** Can make beep increase in pitch as more meds per day added ****
'**D** done Add a test to see if mains pluses present or not, use internal timer interupt if its not ****
'	**** Ideally needs hardware to change between mains/bat as well - germnaium diodes?
'**E** done Allow user to specfify a day to NOT take meds if med count =1 (sat night for Tony S)
'**F** done Allow user to pre-empt the reminder somehow
'**G** done The reminder to put the bottle back needs to be more urgent pip-pip-pip   pip-pip-pip 
'**H** Remove pip at 24 hr rollover (2 of them) 
'**I** done Remove InteruptCounterMax variables and logic
'**J** Test for bottle missing at medtime and generate alarm, rather than assume pill taken.
'**K** Tidy code indents ect
'**L** done Swap outputs 1 and 2 then add tune during the skiped med istead of a boring beep
'**M** Experiment with checking IR level and looking for an abrubt change in level, rather than a crossing of a threshold.
'compare level now against a rolling average of last few reads
'this might be a better way of detecting bottle up or foil up if sunlight is involved in the mix.
'be a problem if the sensor is swamped - but you could probably detect that as well.

'**N** Music doesnt play properly when running on mains. Does the interupt screw it?
'**O** done its very quiet in the first production prototype case...No holes to let sound out!
