Changing declared variables names on the fly

[jessey]

Hi Sayzer,

Thanks for your explanation about the For-Next loop, I think I can grasp the concept of the Index For-Next loop now but what I don't understand is how do I write the values to the different eeprom locations. I added some push buttons to your code to try and increase and decrease the OnTime & OffTime variables and the Hour variable in an attempt to flash an Led but can't get it to work. Could you please help me to understand how to write to the different eeprom locations?

Thanks
jessey

WRITE will work at run-time
EEPROM or DATA will work at Programming time


DATA @101,10 will write 10 at address 101 at programming time
WRITE 101,10 will write 10 at adress 101 at run time

i will read-back the whole post here, but it think you already understand the concept... OR i'm too drunk ... no way!

Hello Sayzer,

Thanks for your code example, I like the way the IncrFlag and the DecrFlag variables work in that you don't have to set it back to 0 and just use "IF DecrFlag THEN", that's cool. I tried your code and it didn't work as posted, in order to save the OnTime & OffTime I had to place Index.0=OffTime & Index.1=OnTime before the write then it would save ok. Another thing I had to do in order to save the on/off times was to change the FOR-NEXT loop from 1 - 10 to 0 - 1 then it saved?

You and Steve say that EEPROM or DATA will work at Programming time and you have EEPROM 1,[1,2,3,4,5,6,7,8,9,10,101,102,103,104,105,106,107,1 08,109,110] but when I program the code then OnTime shows 2 and OffTime shows 255. As far as I can figure location 1 is OnTime and when I replace 1 in the above EEPROM statement with 8 then after programming then OnTime dose show 8 but I can't figure out how to get address 101 to show anything but 255 using the EEPROM?

Am I correct in placing Index.1 and Index.0 before the write and if so how would I write to all the other addresses? I've been playing around with the code and can't seem to get it working properly. I'd like to be able to add additional subroutines to program additional on off times.

Thanks
jessey

Jessey,

I think you are thinking about FOR loop in a different way.
Index variable is not an array variable.

So you need to go back to using FOR Index=1 TO 10.


Also, Index.1=OnTime and Index.0=OffTime do nothing in the code for you.
You are, I think, confusing with Arrays here.

Can you be more specific about your idea?
May be I got it not good enough.

Hi Sayzer,

Well I'm finally getting somewhere, I was way off track in my thinking but I think I'm getting closer now. This code works but I still have a few questions for you.

In this code below that I wrote, I had to change the "READ Index +100, OffTime" to "READ Index +10, OffTime" when using the "EEPROM 1,[1,3,5....]" statement to get the OffTimes to display to the Lcd which makes sense because I only have 10 OnTimes and 10 OffTimes but when I don't use the "EEPROM 1,[1,3,5....]" statement and just set and save the different times to the eeprom then I have to use "READ Index +100, OffTime" in order to make it work otherwise my OffTimes will show 255 and won't change? Why is that?

Another question, what does the EEPROM 1, in the "EEPROM 1,[1,3,5....]" statement make reference to. Can I have multiple eerpom statements like "EEPROM 1,[1,3,5....]", "EEPROM 2,[1,3,5....]", "EEPROM 3,[1,3,5....]" ect. ect, for different sets of variables?

Here is one of the segments of code that I'd like to change in an attachment here if you want to see what I'm trying to accomplish.This code uses 1404 bytes in my program and I thought I could use your example code to save some code space for this part and if it works out then I can save a lot in other parts of my program as well.

Thanks

jessey, This should save you a few bytes......

_On con 1
COUNTER VAR BYTE
Timer_Is var byte[13]
Clock_Mode var byte
On_Am_Pm_Mode VAR BYTE[13]
Hours VAR BYTE
On_Timer_Hour VAR BYTE[13]
Minutes VAR BYTE
On_Timer_Min VAR BYTE[13]
Seconds VAR BYTE
On_Timer_Sec VAR BYTE[13]


Check_The_Timers_Relay: 'this code uses 1404 bytes
COUNTER = 1
WHILE COUNTER < 13 'LOOP 12 TIMES
IF Timer_Is(COUNTER) = _On then
IF Clock_Mode = On_Am_Pm_Mode(COUNTER) THEN ' this checks the am/pm mode for on Timer
IF Hours = On_Timer_Hour(COUNTER) THEN
IF Minutes = On_Timer_Min(COUNTER) then
IF Seconds = On_Timer_Sec(COUNTER) THEN
GOSUB Turn_On_The_Relay
ENDIF
ENDIF
ENDIF
endif
IF Clock_Mode = Off_Am_Pm_Mode(COUNTER) THEN
IF Hours = Off_Timer_Hour(COUNTER) THEN
IF Minutes = Off_Timer_Min(COUNTER) then
IF Seconds = Off_Timer_Sec(COUNTER) THEN
GOSUB Turn_Off_The_Relay
ENDIF
ENDIF
ENDIF
endif
ENDIF
COUNTER = COUNTER + 1
WEND
RETURN

Another question, what does the EEPROM 1, in the "EEPROM 1,[1,3,5....]" statement make reference to. Can I have multiple eerpom statements like "EEPROM 1,[1,3,5....]", "EEPROM 2,[1,3,5....]", "EEPROM 3,[1,3,5....]" ect. ect, for different sets of variables?.....

Jessey,

I did not take look at your code now but for your EEPROM question, here is the key.

If you look at the help file or the manual etc..., you will understand the followings.

Example:
EEPROM 1,[1,3,5,7,9,11,$C0,"A",%10100101]
1 is the start address for EEPROM location.
This command will do the following.

Store value 1 on Location 1
Store value 3 on Location 2
Store value 5 on Location 3.
Store value 7 on Location 4.
Store value 9 on Location 5.
Store value 11 on Location 6.
Store value $C0 on Location 7.
Store value "A" on Location 8.
Store value %10100101 on Location 9.


Therefore, once you start from a location on epprom to store some values, then you can not cross that address range by another eeprom command.

Example:
EEPROM 5,["A","B","C","D"]

This will store "A" , "B" , "C" , and "D" on epprom locations 5,6,7,and 8 respectively. This way, you are having locations from 5 to 8 reserved by this epprom command.

Then if you have another EEPROM command like EEPROM 3,[90,100,25,70] then this epprom command will try to write on locations 3,4,5, and 6.

Now, you get two EEPROM commands trying to write on same locations at 5 and 6.

Thus, you get a collision in EEPROM. You will need to change the location in one of these eeprom commands.

As long as you have no collision, you are free to use the given space by your epprom with multiple epprom commands.



Is it clear now?
