Searching these forums is a good place to start. For example:

There seem to be a few posts with info and solutions to this.

I agree - @mnfisher, @chipfryer27 and others provide so much valuable help on this forum and every contribution they make is appreciated so much. It would be impossible for this forum to exist without the selflessness and thoughtfulness of these people. I hope the following does no dilute this messa...

Yes, you can have custom images for the face of the gauge and the central 'cap'. The attached is an example I did a long time ago (for v9). It uses the "Gauge" primitive rather than the "Circular Gauge" component, but the principle is the same. One of the gauges has custom images.

The "Circular Gauge" component is deliberately cut-down to make it easier to use. The files for the images should be image files (png, bmp, etc). Alternatively, you could use the base gauge component as this has some built-in range settings. It's complicated to use and is hidden. To find i...

You can copied the gauge from a Web Developer project into a PC Developer project. In general, Web Developer components are very different to PC Developer and Embedded Flowcode components and so you can't use them in the wrong type of project. For a PC Developer project, you need to use a different ...

Thanks for the update. Unfortunately I don't have access to a device that can run Safari. Please let me know if you find anything.

I dug a little deeper and made a suggested edit to the code. Can you please try the attached and let me know if it works or not. If it's still not working, can you try opening the console window in Safari. I don't know how to do this, but the internet offers some help (search for "debug safari ...

Thanks. It displays ok on my browser. It's the dials and the chart that are not displaying in your image. I know these components display ok on Android mobile phones (e.g. using Chrome) so there must be something on the Apple devices that is not compatible for some reason. These components use Googl...

Please post a project that shows this problem and we'll have a look (post both the source Flowcode project and the generated html file). Also, can you please post an image of what it looks like when displaying correctly. Also, please tell us the exact versions of the browsers that are showing the pr...

Thanks, Deqiang. I will pass on your comments for STM32 tutorials. We believe that one of Flowcode's strengths is that code written for one set of chips can be ported to another chip family with minimal effort. There are some issues that do not port seamlessly - e.g. interrupts - but most features s...
