Hello, Do you have any examples on using the flowkit with ECIO. I tried a simple program on the ECIO-28 and attached it to the flowkit. It says "COULD NOT COMMUNICATE WITH ICD. PLEASE CONNECT AN APPROPRIATE ICD UNIT (EG. EB006 V7) AND TRY AGAIN. Does this mean I have to connect it to the EB-006? sho...

I understand it's better to use PID on a 10-bit device due to the difficulty in computing without going below or above 255. Maybe if you could send the same PID program in your example with a few more "NOTES" and information so that we can edit it to suit our application. It would be easier to learn...

Hello Benj, I am using your EB-005 LCD Board. I just want to be sure I don't damage the LCD Board. However it is working when the jumper is connected to the +14v of the EB-006 programmer board. It doesn't have any display when connected to the +V of the EB-006 Board. The EB-006 Board is uses externa...

Hello Benj, Eager to start while waiting for the MMC/SD Card Reader, I tried to work with what I had--the LCD Board and Keypad with the PIC16f877A on the EB-006. When I tried the air to fuel ratio example on flowbook, I couldn't get a display out. When connecting the LCD board power to +14v of the E...

Hi Benj, Thanks for the clarification. I realize that I do not need to play MP3. WAV files would be fine. It is really your article that I should work with and take it a step further by incorporating the command inputs through the keypad and maybe some switches as an added feature. This means that t...

Hello, I am thinking of building an E-blocks MP3 player. Is this possible if I were to use the following: 1. EB-061 with ECIO-40 2. EB-021 MIDI Board to output to earphones or speakers 3. EB-037 SD/MMC Card Reader to store the music 4. EB-005 LCD Board to show status (playing, pause, stop) and music...

I have seen the PID example and I'm sorry it's too complicated for me. Is there a simple way of doing PID control?
I would like to set the PWM speed to slow down when approaching the target and slowly go back if it overshoots. Does it have to be THAT complicated?

Thanks Medelec for the demonstration. I was really using this for my educational purposes---as a way to learn more about accurate ADC reading for other applications.

Now, I will attempt to apply the concept on a 16F88 or 16F877a.

Thanks again!

Thanks Sean for your very clear explanation! It puts things into proper perspective for me.

Thanks Sean! That works fine.

Errr...can we work around the computations to get another digit? I want to get figures like 1.234 volts?

Is the factor really 2 or is it 1.96 or another number?

Thanks again!

Yehey! It works!!!

Thanks Steve!

I tried the Digital Volt meter sample program on my MIAC. That works fine resulting it voltage readings of up to 1 decimal point. In my attempt to get a reading of up to 2 decimal points, I edited the program and when I download this to my MIAC, I get a zero reading instead. Can you please check my ...

Thanks Tiny, I already did a system restore and my flowcode is working now.
Steve, just tell me if you want me to try something out so I can still get my 4.3 going.

My anti virus software Norman has always been there. Why should it cause any problem now?

What do you suggest I do as an immediate solution to be able to use my Flowcode again? I wouldn't mind trying it again later to help give you info but just for emergency purposes, do I just do system restore?

Hello Steve,

I'm running on windows 7 64-bit. Sorry, I don't know how to check the registry thing.

The program i am trying to run has ADC, PWM and switches.

I hope this helps.

By the way, I didn't try to install the full version of Flowcode V4.3. I only did the patch.

Thanks!

The same thing happened to me. It says : "Flowcode could not load one of the components in the file because it is not registered on this machine. Install the necessary components before this file." I think it's referring to the PWM and ADC components. Creating a new file works. Help! I need to work ...

Hello,
Sorry but I didn't get how to produce sine wave in flowcode
How is this done in flowcode for sine wave to go negative?
I would like to try to do this too using PIC16F628a.

Thanks Medelec I think I can work with 122hz and I don't want to confuse my loops with the interrupt timer

That idea should come in handy for another application, though

Thanks so much for pointing that out. It's fine now. I know i need a 1mhz crystal to get 61hz. Unfortunately, we can't find a 1mhz in the market at the moment

Hello, I am trying to program a 16F877a using the EB-006 Board with clock speed set =1,000,000 Hz PWM is set at Period=255 Clock Source= clk/16 Crystal we are using is 19mhz. This is supposed to have a frequency of 61.03516 Hz. When we test the 16f877a with a scope, we read 1kHz. Its as if the clock...

WOW! I believe it IS a memory problem.

The ECIO-28 has a steady light on when the program is to simply light up some LEDs.

I guess I'll just go ahead and use the ECIO-40 for my application.

Thanks Benj for your quick reply. More power to you and Matrix Multimedia!

I was able to compile and program the ECIO-40 with Flowcode 4.1.1.55 on Windows vista. At first the device manager did not recognize the ECIO and if ever it does, it would be for only a second- not enough time to untick the power management option. This was solved when I used the ECIO programmer and...

I once found someone's post with an attached program with the fading LED. When simulating his program, the LEDs Component actually fades. His LEDs Component even has 3 colors in one component RED-GREEN-BLUE. Sorry, I can't find the thread right now. How is this done? How do we give individual LEDs t...

Hi Benj, Ok...typical of all of us....after posting my earlier reply, I did some checking on compiler problems and came across this thread. http://www.matrixmultimedia.com/mmforums/viewtopic.php?f=29&t=6481#p13846 I downloaded the zip file and tried to do compile to chip....VOILA! IT WORKS!!! :mrgre...

Hi Benj, I tried to change target chip to 16f88 on V3 and opened it on V4. I was able to open it. I configured the target chip and tried: 1. xtal 2. xtal and enabled LVP 3. autodetect For your info, I'm using Vista SP1. Upon compiling to chip on my HP-488 board, it simply says Launching the compiler...
