Something I ran into also. Has something to do with reading state of pin for toggle, a problem if pin is set to analog, I think. Anyway, a simple reliable method to toggle a pin is to add 1 to the...

And if you want to add to time values from DS1307 then convert to decimal before addition --

sec = (RTCsec >> 4)*10 + (RTCsec & $F)

I made a typo error above

should be --

second = (sec >> 4)*16 + (sec & $F)

second is variable value which displays sec digits when second is displayed as hex number.

second = (sec >> 1)*16 + (sec & $F) to convert time number sec to hex value second that displays time...

rtchour = sethour

If sethour is 12 noon then rtchour must be a hex value that creates the digits 12

Perhaps this will help. Note input time number in hex --

hserin [hex2 wb1]


Clock_set:

GOSUB GET_TIME

hserout [ "0 second ",hex sec,13,10]

I use DS1307 a lot and it must be super reliable for years, otherwise concentrator sunlight could start fires or melt rocks. I have not read your code but have experience strange RTC behavior and...

Very interesting. I did not know about DS1370 battery voltage sensitivity. I used long-life CR 1620 for 10 year clock service and never checked battery voltages with a meter. Something to...

A schematic showing DS1307, never had trouble except once when a circuit mistake overheated the voltage supply and the clock with battery gave similar data.

According to data sheet 18F4620 making one port analog makes all smaller number ports analog which interferes with TOGGLE. IF AN5 is analog then AN0 thru AN4 are also analog, like a pyramid. TOGGLE...

OK. That makes sense. So, excepting new features, both will produce the same hex file from the same source code?
