Fixed with help from Medelec.

Hi Martin, Thank you for your fast answer, that did the trick for the frequency not changing. Leaves the issue with duty cycle, but that is not important to me. Is there anywhere on the forum a list of things that do not work / need a work around? It could have saved me a few hours work if I had kno...

Hi, For a test I need to simulate a load cell. The cell outputs a block signal of about 16470 Hz with no load and about 17850Hz at full load. I have the latest version of Flowcode V6, a board with a PIC 18F4520 at 8 mHz. HS-PLL --> 32mHz. I was thinking about using PWM and changing the base frequenc...

Dank je

I have a board with a 8 MHz crystal, In my configuration settings I have set HS PLL enabled (freq=4xFosc1), so internal clock is 32 MHZ. In general options should I set the clock at 32MHz, or should I set it at 8MHz (and does it calculatie 8x4=32 itself)? If I want to use a timer2 interrupt, I assum...

Hi, In a program I have to invert a Bool variable. I did not want to use If A = 0 then 1 else 0, but just toggle the value: In other C dialects it would be: A = !A ( where ! means NOT) Since there does not seem to be a "!" in Flowcode, I used NOT So I thought A = NOT A would do the trick, ...

Is it possible to synchonise timer2 with an event like interupt on port B pin 0 change? or can I start the interupt timer at that moment? I have to do some actions which have to happen within certain time window and waiting for the next timer interupt and start then could be too late. Does timer2 ke...

Medelec,
thank you for your tip about the timer 2 program, it is verry usefull.

I have searched the forum but could not find an answer. I wat to use timer0 interupt. On the internet there are some programs where you can calculate the values (prescaler and offset) to get the desired frequency/time In properties of timer0 interrupt you can set the prescaler rate, how do you progr...

I do not understand how you convert the numbers you want to display to the ram write box (in your picture).

What should I use if I want to display 14,31,27,21,23,21,27,14, so FCD_LCDDisplay0_RAM_Write(0,14,31,27,21,23,21,27,14);

Hi Martin, Do you know how this should be done in Flowcode 6? If I compile your program I get errors: Volume Up Down_v6.c(686:2): error: unknown identifier 'FCD_LCDDisplay0_RAM_Write' Volume Up Down_v6.c(686:2): error: failed to generate expression Volume Up Down_v6.c(687:2): error: unknown identifi...

Yes, the comma was the problem.

Is there a limitation on the length of the filename of a Flowcode program? I saved my program, renamed it and since it does not compile (with this cryptic massage), while the old (identical) program with a shorter name compiles without error. PicPLC Liftbesturing V19C FC6 MONO, EMOD en Kollmorgen Mo...

@Martin (Medelex35) I do not use mechanical switches, I use a rotary encoder that is also used at VVVF drives. F.I. a Wachendorff WDG58 The encoder has 2 outputs A and B and a resolution of 1024 pulses per revelation. There is no bounce on the outputs. With 1024 pulses per revelation, a delay would ...

I did not combine results. The fault does not always occur. I have had this problem 2 or 3 times. Because I knew it worked before I assumed I made an error somewhere. I started to disable pictograms in my program until I only kept the part of the program that did not work, everything looked fine but...

Does it make any difference of I assign a Bool variable wit True or 1 / False of 0? I have a program in which I assign Boole versiables with 1 and 0 In decisions I also check if Bool variable = 1 For some Odd reason the program sometimes seems to compile wrong and makes wrong decisions at these bool...

Hi Martin, Thanks for the effort. @Benj It is/was stored on a nas. I saved the file before building the program. When the programming was finisched somehow the power of the NAS was cut of. Due to the fact that the file was saved just before, I did not save the program local an stopped working at the...

Hi Martin,

I sent jou the file by PM.

Thanks for having a look at it.

First make sure you have the latest V6 then try and open the file again. You can try looking for.001 file from the project directory and rename to .fcfx That file is a backup copy. If you want to keep the file that could be corrupted the rename it before completing the above step, so you don't have...

When I try to open my last Flowcode program, I get the error:

Failed to open document.
Can not load <schema> without a block header

OK



Can this be repaired?

Hi DavidA,

That seems to do the trick.

No limitations in boostC.

Now it also works without administrator rights.

Thank you verry much,


Marcel

Hi Benj,

Any chance on solving my problem?

Removing pins is not a good method. I have had eeproms with pins broken of at the casing, simply using a soldering iron and some solder was enough to create a temporary pin to read the chip in a programmer. Blowing a programming pin with high voltage would be an option but i would not take the risk ...
