Hello there again. My problem seems to be a unwillingness for the port to open. I made all the settings and used the test file for the RS 232 board, but... I started getting a "unable to open port" message. The device manager does indicate the usb to serial device as being connected though...

Thanks Ben, I tried to run the eb015 test "Hello world" program, however I get no data transfer in either direction. Using the hyperterminal and checking all the settings, still nothing..The hyperterminal program crashed a few times while trying to send data.??? How would I go about confir...

Hello, Different Rob here. I'm trying to make use out of my RS232 board (eb015). I discovered after I purchased it that my laptop does not have a serial port connector. I see there is a USB converter (eb039), however I needed something quick so I bought a USB to serial converter (from Elecom). I can...

Hello, need help. I'm trying to use a 16f887 in my matrix version 3 development board. It came with a 16f877A, which of course worked fine. I guess there is a setting I don't have correct. I'm getting strange behavior, like the program stopping in mid-stream.. The major difference I am aware of is t...

I,m working on the digital thermometer project, but instead of using an NTC I'm using a temperature sensor (lm34DZ). Works ok except that the output from the temp sensor seems to be very erratic. ie. varying by 5-6 degrees for no apparent reason. The sensor output change as per temp change is 10mV/d...

Thanks again, I will give it a shot.

Hello, I hope I attached the correct file.... A slightly modified version of this small simple program to convert degrees C into degrees F and visa versa. Works fine on the computer but the calculation gets all messed up in real life (on the board). Maybe it has something to do with the way the micr...

Wow thanks!
A bit scary how you could read my mind as I didn't think I relayed what I was trying to do very well.

After a quick look and reading your description though it looks right on.
Thanks again, Rob

Hello, I have a question regarding the intro to micro controller course that I downloaded. I want to check out some of the labs, but I get a message that the labs are not available with the free version (I have a licensed ver.) I believe I first downloaded the course before I had a licensed copy so ...

A different array question; I'm trying to acquire a three digit number to use in a calculation. I used an array namely (degcalc[2] to collect the numbers from a keypad. I understand that these are three individual numbers stored in a variable of the same name. My question is how would I go about con...

Hello, I'm trying out the "record" project from the van Dam book. I believe I have it working...well sort of. (using the SPI/DAC board) EB-13 I believe) I don't have a microphone so I'm inputting a simple sign wave. I can record(?) and playback the tone (coming from a func. generator) howe...

Thanks Steve,

I'm sticking with version 4.2 for now.

I made the changes to the H file. Works like a charm now.
You guys are good!

Thanks, Rob

I guess once the fix for this problem (the components) is in place I will download version 4.3 again. As you know, my original problem was that I could not compile the Air-to-fuel problem. Will version 4.3 fix this problem? Some of the other problems that include C-code compile ok, is the problem re...

Hi Steve, Not sure if you still need the *ocx file version number, but it is 4.1.0.2. (for the LED,LED array, and LCD) I will try installing version 4.3 again in a bit. To be honest, I'm a little nervous after what happened last time. It seems to be working though, judging from the other write-ups. ...

The fix I'm really interested in is being able to load programs that have their own C-code (the C-code block) as the air-to-fuel program has.

Thanks, Rob

Hi Steve,

I am running Flowcode in English.

Thanks, Rob

Steve,

Finally some success.

I downloaded version 4.2 and it is currently running on my computer. It didn't like something about ver. 4.3 I guess?
Some things are still a little loopy with the component icons,(showing the wrong icon) but it is much better than before.

Rob

Steve, Please let me know what I should do next. Obviously I cannot accept this final result while having paid good money for the software. Not sure if this helps at all but here is some info on the error messages: I only get the message when trying to place switches, leds, led arrays, lcd display. ...

I sent the log file to the support e-mail.
I'm in Japan and it's time for bed.
Please send me something I can try in the morning.

Thanks, Rob

please reply as I would like to get this fixed asap..

I got the file now, but it's too big to send I guess.
(max size 256kB)? The file is 1Meg.

Can I send it another way?

got the file.
It wont let me enclose it, file too big. 1Meg.
can I e-mail it?

Yes, I am running XP.

So the log file should be a text file named "log" located at the C:/ root directory? Sounds pretty simple, but....
I don't see it, and tried it twice.
Is there another way to do this?

Thanks,
Rob

another clue to the puzzle;
when I install the hard copy I received 4.0.0.53, (no upgrade) it places different components than what I'm choosing.
For instances if I select a switch it gives me a lcd display, and when I select a 7 segment display it places the formula flowcode box.
Really weird.

Rob

"C:\Documents and Settings\Rob\Desktop\FlowcodeV4.exe" "/log c:\log.txt"

this is what the target line looked like after I added the end bit.
Seems to be the same.
