Porgramming a decimal number For LCD Using flowcode V4.5

[DannyBerry]

Can anybody show a way to put in a number with a decimal in it for a 16x2 LCD using flowcode? I know what the binary address is ..11100010....just don't know how to go about entering it into flowcode file.

Thanks,
Danny

Hi Danny, I don’t know if this will help you but I just broke the number down and did two PrintString’s to the LCD for numbers each side to the decimal point. I did a third PrintString (“.”) write for the decimal point.
Have a great day!

i was wondering that also, i have this huge fcf i've been working on the last couple days,--> in the main menu when you select dynamic by hitting the up button once, then the enter/exit button once, then scroll with up down to see numbers, ......you'll see i made it print number "variable pulsewidth", the number is in 100 u/s increments from 100u/s to 20m/s, so (3=point3m/s) (31=3.1m/s) (156=15.6m/s) and so on, i would like to use string manipulation to simply put a decimal before the last number in this menu selection only, so later i can use a print string to add text so it makes sense to other people that use this project or wants to build it, how ever i've never done a string manipulation prior .... to note this file takes minutes to open because of how many macros i used, how ever it does work good on hardware, thanks

That's what was needed...Thanks Werner

Have a great day also!

Hi Werner,

I can't make out what the 4th macro from the bottem says: PrintNumber(length..?..digit)

Also I think the first one at the top says: PrintASCII("AT:") is this correct...what I mean is It's hard to read..

Thanks,

Danny

[DannyBerry]

OK Werner,

Here's my interpretation...Of what you show in the Jpeg...Now can you get it to count for me or make corrections to what I have.

I got it to simulate in flowcode showing 00.00


Thanks,

Danny

It says "LCDDisplay(0)Printumber(TotalPc)" TotalPc in reference to one of my variables.

Yes Danny, you are correct. For my program I needed a reference as to where something was so i stated for example: "AT: 15.75" like 15 3/4" inch. If I get time I will have a look at your program tonight.
Have a great day!

what me and danny are trying to do is to put a decimal before the last number, like in file, but the number may be single, double, or tripple digit.... werner,im totally confused by your variables, could you modify the file below

Hi Brandon and Brother Danny, Sorry I confused you! I just grabbed a little code from a large program hoping to give you an idea. After looking at it I should have given you more sorry. I am sure one of my Buddy’s listed in my signature would have a much better way of doing it but this is the way I did it: Get keypad numbers than split the number into two variables, one for left side of decimal and one for right side of decimal. My trick was to put the decimal point in a fixed position on the LCE like 4,0. Then when you go to display to LCD using if statements. Please take a look at the program below and go to the Macro NumberCalc tab this is where the number manipulation takes place I think you will see what I did? Sorry I can’t better describe it Buddy!! This program is for an auto wire cutter. Basically you enter the number of pc you want than enter the length you would like the wire cut to. If you run the program you have to push the Blade up button in order for the program to continue. Input how many and length and hold the blade button down so the program will go. The program of course runs much faster on the pic so I would not enter a length number more than 10 pc and 01.00” or it will take too long to complete. You will be able to see how the program displays the decimal number. I hope this gives you some ideas Buddy!
Have a great day Buddy!

Ok Ok Ok I got it….. or should I say my Professor and John have it correct! Please take a look at: http://www.matrixmultimedia.com/mmforum ... 326#p20326it is exactly what you want and simply wonderful! You can do it easy using Left$ and Right$ to display. Thanks again to Martin and John!! That was easy!!
Your Friend,
Werner

nope totally confused still, the only way im gonna understand this is if someone modifys my "string manipulation help" file, reason why is because thats the only thing in the flowchart, i tried reverse engineering it but it left me scratching my head, thanks for trying to help me out on that

[Werner]

Sorry Buddy, This may be the easyest way for you to get what you are looking for? The Flowcode file is just part of what I think you need but might give you an idea? I will PM you and I will try getting you there on the phone I am short on time tonight.
Have a great evening Buddy!

werner, that one is easy because your creating 2 variables and naming the outputs then deciding which line to put them on, in this case it would be simplier to just print string on it as it would work the same way, i gave a bad example file should have used this example

Hi Brandon,

You can do it easy using Left$ and Right$ to display.

Werner was spot on!
You can use Left$ and Right$ to display!
I have modified your flowchart using Left$ and Right$ string manipulation.
Format is
Right$(String,number of chars)

E.g

Code: Select all

Decimal_Number = Right$(PulseWidthString, 1)

If PulseWidthString = "32" then the 1st char on the right is 2
so Decimal_Number = 2
Format is
Left$(String,number of chars)
If the above said

Code: Select all

Decimal_Number = Left$(PulseWidthString, 1)

If PulseWidthString = "32" then the 1st char on the left is 2
so Decimal_Number = 3

thanks martin, i knew werner linked me the right deal but i couldnt get past the variables, thanks for fixing this file for me, but is there any way to do that so it doesnt erase the line

[medelec35]

Your welcome Brandon.

is there any way to do that so it doesnt erase the line

Do you mean like this?

Martin

[Werner]

Thanks Martin! Great examples! It always makes things much easier when you have a great example!
I think Brandon can run with this.
Have a great day Guys!

martin, i havent had time to study it yet but it works great in simulation although it doesnt compile, has string left error codes, below is the full project, some of the features dont work in simulation

[medelec35]

Hmm odd that Flowchart has accepted a integer argument rather than correct string argument in the string calculation box.
Still I have corrected flowchart, and should compile ok.

I will correct the your other flowchart soon when i get a chance.

Martin

[medelec35]

I have corrected pic flow string.fcf so it compiles ok, and I have added a call to timer2 module at the bottom of main (needs removing before sending to chip!) since timer1 and timer2 do not simulate (thank goodness they all simulate in V5 )

So if you run your flowchart and make sure it works the way you have intended.

Anything that's not working, if you let me know I will see if I can correct it for you.

Or even better, burn to chip. nothing beats testing on hardware.

Martin

[brandonb]

hey martin, your the man, that worked great, i cant thank you enough, you know im probably gonna have some questions on this flowcode for sure, you said

Hmm odd it flowchart accepted a integer argument rather than correct string argument in the string calculation box

this chip is weird, i ran into a couple problems also, i can't run lcd off d port,i cant have tmr0&tmr1 running together, but tmr0&tmr2 runs fine together, i also cant have a port interrupt and a int on pin interrupt at the same time, i understand how the int/port one could cause an issue because the pin B0 would share two different interrupts..... dont worry about changing the files, i modified the end of the file to eliminate a zero and added a string, this is a awsome project, and no way possible could i have done it with out you..... <<<i updated file 12/12/11>>>
