Re: Intergrated Shiftlight in a BA Falcon tacho guage

Have you considered accessing the CAN bus directly? The information you need is obviously available there if the tacho is driven that way. There are plenty of resources available to help you with access and this might be a tidier solution. Asking for both hardware and software design for your basic ...

Re: DMD scrolling Speed control

Scrolling speed is determined by how often you step the marquee. If you are using the original DMD library this is done by dmd.stepMarquee(), or for DMD2 it is dmd.marqueeScrollX(), which you execute within a timed loop. So all you need to do is adjust the timing of the loop to alter scrolling speed.

Re: why so many pins for 32x16 DMD?

The SPI interface requires the 3 lines: - PIN_DMD_CLK - PIN_DMD_SCLK - PIN_DMD_R_DATA There is plenty of resources available which explain how this interface works. The DMD is arranged in 4 blocks and the 2 lines: - PIN_DMD_A - PIN_DMD_B are used to select which 1 of the 4 is currently active. And f...

Re: runnig text Arabic

Have a look at this topic . There is a file attached to one post called "MyBigFont.h". Have a look at that file. It should help explain how these fonts work. There are comments added throughout as well as a description of how it is built at the end of the file. This might help you to construct your ...

Re: New beta release "DMD2" Library

Scrolling with multiple displays does not perform very well the way the DMD2 library currently works at the moment. It is a result of the way it works, not the actual scrolling function. I would suggest you use the original DMD library. It certainly lacks some of the features of the DMD2 library, bu...

Re: Without Arduino

No. There is no way to control the LEDs (except for all LEDs OFF) without something driving the inputs.

Re: The word cannot display correctly

I had used arduino uno and also tried the sample sketches supplied with the library. The result is the dmd was working but the pattern of led are not lit as usual. This indicates that something is probably wrong with your setup rather than your code. I had power the dmd using usb port only without ...

Re: The word cannot display correctly

Well it could be either, or even something else. We have no way of telling without more details - such as seeing your code - are you using a Uno or something else? - hardware/wiring configuration. Have you tried the sample sketches supplied with the libraries? If they work, then it is a problem with...

Re: Problem with getting new font to work

Supposedly the <brackets> tells the pre-compiler to look in the default include directory, "quotes" tells it to look in your working directory (where your .ino file is) but I think it will also look in the default include directory if it doesn't find the file. When it is a newly added file, you do n...

Re: are these being made still?

Pretty sure these were a Freetronics project and they appear to be discontinued. They are not real active on the forum so it might pay to try sending an email to support@freetronics.com to see if they can offer you any hope.
