Hi all, Again :shock: I have some news good and slightly Less good :lol: I have fixed the error when recieving two strings, The problem seems to be in the way of writing the strings with VisualBasic and Flowcode's RS232 Macro NumBytes() when receiving strings. I hope I have said this wright forgive ...

I just wanted to give you guys a quick reply, I have figured out that in the Receive_RS232 Macro, That only the top part of the code is exequted properly. What I mean By that is: ReceiveString Compare_Strings --If Strings are the same Yes >>> Receive StepperNumber_TiltingAngle >>> Convert to Integer...

Hi Again, I'm hoping somebody has the time to help me figure out this problem i'm having. The problem is as follow: --- I have made a visual basic program that calculates different angles based on two sets of gps coordinates. After I clicked the button "Request To Send" the visual basic program send...

He Benj Thanks for your explanation, So basically for every part of information you would send a Identifier byte with it, Im going to try this ASAP and let you know what the progress is. But how do I receive a byte ore multiple bytes, the only option the RS232 macro gives me is to receive Char(s) or...

Hi all, I finally figure it out on how to calculate the different angles. But when one problems is solved it creates a nother. I want to send the data that I have calculated and modified via the RS232 port, that works very nice but I dont know how to figure out How I can tell to the microcontroller ...

Hi Everyone, My stepper motors are working as I inteded. Now for my next challange I need to do some heavy mathematical calculations, At least I think. What I need to calculate are the following things: The angle between different co-ordinates. Umm let me say different: I need to calculated the angl...

Hi, all I have made a simple program that turns the stepper motor every 45 degrees or 25 steps or 50 steps depending on how you set the stepping mode. In my case I will use full-stepping mode thus, 25 steps result in 45 degree turn. In my program I have used a switch icon with 4 different outputs. I...

Hi, all Im working on a new application its called a ADS-B Airplane Tracker. The goal of this application is to point a camera in the direction of an airplane by GPS- coordinates. Therefore I want to use 2 stepper motors: - one for the rotating movement - second for the up- down motion of the camera...

Thanks Martin
I Will have look at it tomorrow.
I Will let you knie something.

Hi all, I'm doing a school assignment, here we must write a program for controlling a traffic light. Now if a want to test (simulate) my program in flowcode it doesn't work as aspected. I have setup a interupt routine that keep track of the time, how long each action should take. But the problem is,...

Thanks for the tip Benj.
I will try that when the board has arrived.

Hi all, I have purchased the EB039 to expiriment with USB, but after looking into the datasheet of this eblock, the TX/RX LEDs are not connected. Is there a reason for this. Also how can I simulate the behavior of these leds as if the are connected to these TX/RX pins of the FTDI chip. Regards Jordy

Thanks Martin you are a genius.
It helped me a lot.
Thanks

Hi all, Im working on my rewrite of my aquarium controller, Im currently working on the menu and want to use one button for entering and exiting from the menu. I want to do this by using a short press to go to the next item of the menu and a longer press (2sec) to exit the menu. I dont know how to g...

Martin, I have tryed your program. It shows me the number 1. That means that the program never goes further then printing the next number. But it shows me the time that's is stored into the ds1307 correctly. But it doesn't refresh the data I don't understand because the whole thing is inside a loop....

I have put output in this loop (LED) to check if it will toggle of at the end of this loop but it doesnt. Hope somebody can help me, its very annoying. Regards Jordy Hi Jordy It does not appear to be crashing to me, Reason why LED is on all the time is because at the end of the loop you have got 0>...

Hi all, First of all Im very happy with my flowcode version 5 but I have some trouble with a while loop. In my main program I have a loop built in (bottom), where the data is read from different sensors When it goes into this loop it reads the data from he temp sensor and RTC one time. after that it...

Verry much thanks to you dazz,
Its verry usefull information that you give to me, thanks again.

Regards Jordy

Hi, all I have my aquarium Controller almost up ad running, the only thing I need to do is an automatic callibration of my ph probe. I have searched the web for a while and found only some PH probe vs temperature correction charts, To get that same result you need to do some calculation with difficu...

Thanks steve and gary for your quick reaction,

The solution steve has works best for me and tested this and works perfectly thanks for that.

Regards Jordy

Hi, all Im still working on my aquarium controller, everything works perfectly but one thing I can't figure out thats why I need your help. For the temperature controller section of the software I need to make something like hysteresis so that the heater doesn't kick in on every change of temperatur...

Hi, I have an idea for your next video subject. Maybe you can show us how to interface the new graphical LCDs with something like touchscreen and rotary encoders. And maybe on how to setup a working internet connection with a functional webpage to display adc values. That would be nice Regards Jordy

Hi, sotos

Nice project you have there.
I saw you case for your project and I have a question for you,

How have you made that front panel with menu down up ect. on it.
I'm really interested in that.

Regards Jordy

Hi steve verry verry thanks for your comment.

Hi steve I will look into this article, seems to me the most aceptable to try. With the FAT16 component, when you create a text file (.txt) is it possible to go go down 1 line. just like if you would hit enter on you're keyboard. I want to try one more thing with this component, I hope that I can cr...
