STR function blues...

[bearpawz]

O.K., well I got my pulse count problems solved... Now the only problem is: Does anyone have a good routine on how to convert a number to a string? This is for odometer: so if say I have a mile count of 95,285 miles, I need to display "095285.0" on my display. (and before any one sugests it, using serout will not work: I have to store the string in an array...)

Mean while I'll keep searching the net.

Perfect example of RTFM here... but incase anyone else ever runs into the same problem, the key is the DIG Modefier. Here is the code I came up with:


For lcount = 0 to 9
MsgBuff[9 - Lcount] = OdCountL dig lcount + 48
Next


MsgBuff is an array where I store the VFD messages (kind of like a buffer)

Hi bearpawz,

Along with RTFM, there's UTFM. Because, along with reading it, you have to Understand it.

The largest DIG you can use is 4. This is because the largest number you can have is 65535, which has only 5 digits. So, DIG 9 is out of the question.

Which begs the question, how are you storing mileage of 7 digits (6 + 1 decimal) "095285.0"? It's going to take more than just a word variable.

It can be done, but just not the way you've shown.

Best regards,
Darrel

Your absolutly right about that. One of the graces I have found with DIG is if the digit does not exest (like Dig 9), it returns a 0.. So so far everything looks fine until the word variably I have maxs out at 65535.

Since a 16 bit word is not big enough I have to store half in one word variable and the other half in another.




Some simple code:

OdCountL = OdCountL + 1 ' Increment Low Word Count
If OdCountL = 10000 then ' Roll Over at 9999 (999.9)
OdCountH = OdCountH + 1 ' Increment High Word Count
If OdCountH = 1000 Then ' Roll Over at 999 (999 + 999.9)
OdCountH = 0 ' Zero the High Word Counter
Endif
OdCOuntL = 0 ' Zero the low word counter
Endif

....

For lcount = 0 to 3
MsgBuff[9 - Lcount] = OdCountL dig lcount + 48
Next
For lcount = 0 to 2
MsgBuff[5 - Lcount] = OdCountH dig lcount + 48
Next
