@Ben: With all due respect, we are on different levels as of the moment. I represent a natural man, you represent a corporation, which is rewarding you for your work. I totally respect that, we all need to support our families and survive at the end. Honestly if I listened to every salesperson out t...

Hello all, @Martin: Yes, I am not worried about hardware part, it all works correctly and wired properly 100%. What does not work and/or causing me wonders/hair loss is the software. I am using PICKit2 to load the hex code. The hardware is tiny custom built board for my own experimentation and I am ...

Hello all, This may be a bit off the course of current topic...nevertheless... I am also experimenting with 12F675 and found that external interrupt on pin4, which is GPIO3/MCLR, never works right. I am sure it can be done if MCLR is set to internal and so GPIO3 is available as input, it even works ...

Hello FLJ and welcome to the forum. I am in the same situation and still awaiting reply from somebody proficient and kind enough to explain how 8 bit interfacing is done. See the link : http://www.matrixmultimedia.com/mmforums/viewtopic.php?f=7&t=10034 It looks that it is not much supported... There...

Thanks again for your continuous effort to enlighten me... If you want to use 8-bit data mode, you will need to customize the C code behind the component," this sure sounds easy for someone proficient, which is not the case with me... "Your program is trying to display the ASCII character 31, which ...

Thank you Steve for steering me into right direction. I am afraid that I am still unclear on a few moments as the following: How do I change to 8 bit data, as opposed to 4 bit built in peripheral, should my LCD require? I attached a sample project for your review, if you would be so kind, and would ...

Ben, Thanks for your valuable input. Honestly, I would like to learn specifics of how to display custom characters on an LCD. As far as my knowledge about LCD goes, there are character maps (maybe more than one) preloaded in non-volatile memory of LCD, a character is pulled and pushed onto display b...

Hello all, I am looking into possibility of using 24x2line LCD for my projects. It is fairly standard part as far as I can tell, utilizing one HD44780 and couple HD44100 chips. Since Flowcode does not have native support for this size LCD, what can be done to create a snippet and/or component to use...

Thank you Martin and all others for your very constructive input. Of course I remember my limitations within the free version, but no worries, it gives me a good motivation to obtain the full one, once I develop an appetite for something worthy, bearing in mind that new version 5 is coming soon some...

Hello again! I am so much relieved with your comments and help, before I could not sleep tight...hehe. I'll give it a good test and report results later. It seems that some tricks are unspoken of and there should be a summary of pitfalls to avoid as well as good practices to follow. I believe every ...

Hello again, Here's an update. I built another flowchart using port interrupt for the same purpose to toggle an LED with the port change. I have the following questions: By default there is always PORTB interrupt shown as available, but could it be changed to any other port and masked? I highly susp...

Oh, forgot to mention my Flowcode is the latest available from the web site, it says version 4.3.9.65. On the other note, I successfully ran other projects with simple blinking patterns, there are 6 LEDS to be utilized on the board and 4 push buttons. All seemed to work fine. I guess it could be a b...

Thank you medelec35! Your code worked nicely in both versions HS and XT. PicProg2009 (Velleman's supplied) seem to recognize config settings in each hex file correctly, once loaded into software you see corresponding features checked and/or un-checked. So all I had to do is just hit load and voila i...

Thanks for your responses. I moved to the above referenced thread. I am still having trouble using Velleman PicProg2009 with K8048 board. It looks that something is resetting PIC no matter what I try, however if I remove infinite loop from my chart (out of desperation, of course), compile and load, ...

Hello all and thanks for responses. What confuses me is that when I tried to load hex file, produced by Flowcode, into the PIC and then read it back from PIC consequently saving with different name and comparing those two files gives me difference! I believe there's some conflict and/or overlap of f...

Hello, I am using Flowcode 4 to create simple test code to use in combination with Velleman RS-232 programmer. I have the flowchart simulating nicely on PC but when I load hex into the pic (16F84A with external XT osc. 4Mhz) it does not work right. I have tried all variations and combinations of the...
