Hi Rob,
RTCC can be used for multiple timers in the same time, for example one is
keeping the real time (second,minute, hour, day, month, etc) in incrementing
sequence and other can be used for a process in decrementing sequence, while
the third (or the alarm but not a good idea) for other processes.
The key I found, is using the halfsec as a separate time generation. The
routine for extracting the halfsec rising edge and decrement an user second
is below, maybe you wish to implement in the library in your well structured
style.
Vasile
var bit block_halfsec = high
var byte _1st_second, _2st_second
var byte second_trt = 59, minute_trt = 59
if block_halfsec then
_1st_second = RTCCFG_HALFSEC
block_halfsec = low
end if
if _1st_second == 0 then
_2st_second = RTCCFG_HALFSEC
if _2st_second == 1 then
second_trt = second_trt - 1 ; decrement the user second
_1st_second = 1
end if
else
block_halfsec = high
end if
if second_trt == 255 then
second_trt = 59
minute_trt = minute_trt - 1
end if
