Thanks, I went threw them also and thought it was me.

Is the PIC32MX320F128 pic microcontroller supported by any of the versions of flowcode? I see that there is now a board that is pin compatible with the Arduino uno board that had this device on it . It is called the "chipKIT Uno32" and I was hoping to test it out sometime in the future but must admi...

Thanks for the info John.

Hi Leigh,

Is there a port for the PicKit3 on the module?

Bill

Is it possible to run this module as it's own controller? And if so can V5 flowcode work with this?

one other thing in the not to distant past Microchip tried a hostile bid to take them over. It did not work at the time but it would seem that at some point that they will be swallowed up by an other microcontroller manufature.

I really wish that the interrupt icon in flowcode allowed you to set leading edge on the graphical representation of the chip .It is there in color code but I have not been able to figure out how to use it. That's because that function is not available on the chip your currently using. A chip I kno...

Well I got to run my version last night and after banging my head for a while finally got the control word right and it started as expected . Once threw start up it went into phase but it would not trigger at the right spot. other than that it did what it needed to do with the 2 40us SCR triggers. N...

8200 micro seconds - (32ms * ADC) So delay is range is from 40us to 8200us? No the full range would be 8300 us but you have to allow for the start in our rectifier .In our circumstance we need at least a .2 amp draw to the SCRs so the controller will start the recipe of the charging. I am generatin...

LOL, I was looking over my original version and I forgot to declare that delay=8200
Now I see how I am confusing everyone. My bad, LOL.

Hi gangusgreen, Pot value will either be 0 to 255 (0 to 5V) if read as Byte Or 0 to 1023 if read as Int These will be used to generate required delay. so what do you want delay to be is ADC is reading 0V? What delay to be is ADC is reading 5V? If you can state both delays then a formula can be deri...

"In my opinion, when creating a flowchart Its best to take a step at a time, until you get use to them. Then your wonder how you managed in the past without Flowcode :P" I could not agree with you more. But unfortunatly in this case I need to have it almost finished to check it out because of the av...

What about this? Martin I can give this on a try as well. What I am trying to achieve is a scr firing at a low swing range that would amount to a .2 amp charge at the low end of a battery type rectifier to a full wave that would allow a 20 amp charge . The controller that this board attaches to loo...

The pin that the board has the signal coming into is pin #4 which is the RA3/MCLR/VPP .If you have a better idea than using an interrupt on this pin to trigger the macro I am willing to try another way.

OK , I see what you mean but how do I tell it what pin to look for this on?

OK I have the program written for a 60 hz signal that will come in on pin 4 and I want to trigger an interrupt here on the rising edge but only have the option of both edges. Is there a way to eliminate the falling edge? I am looking to trigger scr's on both swings of the sign wave at 180 deg firing...

Thanks so much. I think this is how he set up the port. I would ask him but he died and left no trace of what he did other than a hex file. So i am trying to duplicate this program in flowcode more for me to understand how this board works than for my company. I have another co worker that has been ...

I am trying to reconstruct a program that a guy I work with made for a board he designed and I think he used the IOC on pin 4 of the 16f688 .I was wondering how you go about doing this with flow code? Thanks in advance for any answers that you all have.

I am following the flowcode instructions from microchip on using their development board and I am using the comparator circuit with the timer and it says to use the TMR0 Overflow interupt but it is not available for the pic16f690 in the drop down window on version 5 .What am I doing wrong? The only ...

So if you use these symbols inside of the icons in flow chart they are really representing "C" in that context.

Thanks Enamul, but what I am looking for is a table as it relates to flowcode 5 not ASCII . They are symbols that mean something to the code you are writing.

Is there a list of symbols that are used with flow code that is printable? As an example of what I am looking for ">>" is a right shift on a port deceleration and "<<" will shift left. Bill

LOL, OK you gave me enough info and time to play and the end result is my LEDs are now FLASHING!!!!! :D Turns out I need to Autoclear the watchdog timer and BAM it worked. THANK YOU for poking me in the right direction. :mrgreen: Now I can move on with my lessons and learn Flowcode and then design m...

OK , I figured out the last issue, it was me - I was plugged into the wrong plug on the board now I am on the device plug on the board and get this Connecting...

OK it notices the pickit3 now but it gives me this error
