Account creation has now been disabled for these forums. Existing users can post here, but any new user wanting to post on this forum should use the Flowcode forum instead: https://www.flowcode.co.uk/forums

For v9 issues you should post on the appropriate Flowcode forums here:

Regarding your issue, you need to install the 8bit PIC toolchain from here:

It sounds like there is a problem with the FCD definition file for that chip. The FCD file attached seems to work for me using V7.3.0.5. The FCD file lives in the "\FCD\PIC" folder of the Flowcode v7 installation location. Can you please post your FCD file and I will compare to see if it i...

As this is an exam, I don't think anyone can create your program for you. But they may be able to help with specific questions.

Sorry - we have no plans to do this at the moment.

In addition, our Introduction to Microcontrollers course might be useful to you. It is written around our newer software and hardware, but many of the concepts are relevant to your setup. Here's a direct link: https://www.matrixtsl.com/resources/files/datasheets/CP4375%20-%20Introduction%20to%20Micr...

The resource tab of this page has the datasheet for the prototype E-Block. All it does is expose the pins of 2 of the connected microcontroller ports.

Also, the original E-Blocks are compatible with v10 of Flowcode.

This error is probably caused by old tags in the Welcome Page, which is generated by our website. I will look into this next week as it should be an easy fix.

Until then, please ignore this error.

V5 of Flowcode is very old now. It may help if you upload a screenshot because I do not understand what you mean by "only the panel part appears". Another thing to try is to ensure Flowcode is white-listed in any anti-malware products you are running. Also, try opening with other target ch...

I have just compared the Flowcode v5 chip definition files for the 18F4682 and 18F4685 and there are no differences that will affect the generated code that handles analogue inputs. So I don't think this is a Flowcode issue. There is a silicon errata note for that family ( see here ) which mentions ...

Enter "driver" in the "Search for resources" box on this page:

https://www.matrixtsl.com/resources/

One of the first results is "EB006 (v8 and older) / HP488 USB Driver", which should be the one you require.

And alternatively you might consider moving to Flowcode v10. All component packs are now free and it is also free for certain chips and boards too.

FC5 is very old now and no longer officially supported. But I will try to help. Please PM me with details of what you have and I will send you some instructions.

Some older posts on this forum may refer to links on www.matrixmultimedia.com, an old web domain that we no longer use. We have moved a lot of the old articles and resources to our matrixtsl.com site and you may be able to find them via a search on this page: https://www.matrixtsl.com/resources/ So ...

I got me electronics degree a long time ago and since then I've mainly been a software engineer, so I'm not in the best place to answer that. Perhaps others on the forum can.

I did have a quick search of the internet and there seem to be a lot of possibilities though.

I would rule out the LDR as the source of the fluctuations and replace it with a potentiometer, just in case the LDR is not providing a constant resistance. If the flicker still exists, then I guess it's the switching of the LEDs or their drivers that is causing the issue. Maybe consider driving the...

You've probably tried this, but increasing the PWM frequency might be an easy way to reduce flicker.

I've personally not used that display with the Pi, but other users may have. Although I have searched these forums and not found any relevant posts.

Hopefully someone who has used it will be able to help.

Great news - thanks for letting us know. I will pass on this information so it can be incorporated into future Flowcode versions.

There is no support for this device in mLoader, so as you discovered you will need to use an alternative programmer. Also, v8 is quite old now and we can offer limited support for it. Especially for old devices like the 12CE674. But I have some suggestions that may help. I think there could be some ...

Great news. Thanks for letting us know.

What happens if you create a new project using that chip and compile that. Do you still get 29K in size? If not, then there is some code within your original project that is causing this issue and you might have to selectively delete more of your code (and components) until you discover what is caus...

Please see the attached and image below. It contains 4 equivalent icons showing variable assignment: Flowcode, C code and two in Assembly code. There are 2 assembly code versions. The first is a copy of how C code statements are converted to assembly by the compiler (I found this by looking at the g...

@Bachman and @chipfryer27 - Thanks for your attempts to solve this fellow user's problem. This forum greatly benefits from users like you sharing your wisdom and time trying to help others - it is much appreciated.

Hopefully this post will help:
