Help convert 24 hour format on axe033 lcd to 12 hour format clock

[Digisapien]

Anyone got any code ideas for clock 24 hour to 12 hour conversion?

Are you trying to use the AXE033 with Clock option in the more typical serial mode with SEROUT command (in which case it cannot be achieved as time & date display is inbuilt as if a message to bottom line) or the i2c mode (where the AXE033 has less capabilities but can read time into PICAXE to manipulate)

Assuming the 24 and 12 hour times are in decimal ...

t12 = t24 Mod 12
If t12 = 0 Then : t12 = 12 : End If

In serial mode. You answered question

That's exactly the code my programmer best friend told me. But the mod function not in the list of lcd commands

 

[Digisapien]

Assuming the 24 and 12 hour times are in decimal ...

t12 = t24 Mod 12
If t12 = 0 Then : t12 = 12 : End If

""" that's exactly what my best friend said do. He's a programmer """". But I don't think mod is a built in lcd command

 

[hippy]

Sorry "MOD" is represented by % or // in PICAXE Basic -

t12 = t24 // 12
if t12 = 0 then : t12 = 12 : end if

Thanks you. If you never told me that % = mod I never would have known

 

[Digisapien]

Is that the actual code. Forgive me. It could just be a syntax example. There variable for time is (0). I'd like to see it expanded

Hello,
Could you describe what hardware your trying to use . For example, an axe033 driven in serial mode by an 18m2. Please post the program your referring to wher "variable for time is (0)". If you are trying to use the axe033 in serial mode, you can't retrieve the time as westaust55 said in post2, so you can't convert it. You would have to run the display and clock in i2c mode, which is more involved.

In the program hippy posted, t24 and t12 are byte variables. Here is his code in a program. Run it in the simulator to see how it works.

#picaxe 18m2
#terminal 4800

symbol t12 = b3 
symbol t24 = b4

t24 = 23	' 11PM / change this number for different 24 hour times to convert

t12 = t24 // 12
if t12 = 0 then : t12 = 12 : end if 

sertxd("Original t24 hour variable = ")
sertxd(#t24,13,10)
sertxd("Converted t12 hour variable = ")
sertxd(#t12,13,10)

end

Good luck,
Rick

In serial mode. You answered question

If you are operating the AXE033 in serial mode, then irrespective of the PICAXE chip used, you cannot alter the format that the time and date are presented.

Using SEROUT <pin>, baudrate, (253, . . . .
with the parameter 0 (zero) initiates a routine within the AXE033 to display the time and date on the bottom line in a pre-defined format.
there is no way to change this presentation using the serial comms mode.

 

[Digisapien]

you right. read and read and thought about it and without back and forth communication there is no way to do it in serial.
