Re: Replacing Tactile Buttons

It probably depends on where and how the board was made - lots of versions around in both surface mount and through hole designs. All you need to do is match the footprint on the PCB. There are plenty of similar switches available. Something like this might fit; they are very common and are availabl...

Re: DMD library, RTC and Ethernet with Arduino Uno?

The DS1307 just uses I2C, the DMD library uses timerone and SPI, and they will play nicely together. The ENC28160 appears to use SPI as well but you will not be able to share the SPI buss as the DMD does not use a chipselect though the ENC28160 does. There may be options available to you for another...

Re: can i use the p10 display upright

What you are after would require a lot of changes to either of the DMD libraries (DMD or DMD2) if you want all the library features. You did not say which library you would like to use. If you just had a limited number of static displays you could possibly use this approach . There are other threads...

Re: how can i create Arabic library font??

salwan, You may not get any response from m_nagy2 as he has not been active on this forum for a couple of years. The 'font.h' file is the actual font file. There isn't any other data for a font. I think you will have a lot of trouble trying to display Arabic on a DMD using the available DMD or DMD2 ...

Re: how to creat Arabic font?

Have a look at this thread. There is a documented font file there which may help you.
And this thread has a crude excel tool which may help you create the characters, or at least help you understand how these font files work.

Re: Connecting Stepduino to different compiler

Just do a web search for 'Arduino burn bootloader' or something similar and you will get heaps of responses with plenty of options. Just another point: if you are powering the stepduino from the USB port make sure that it has the full 5V available at the board, or else power it externally. I'm not s...

Re: Connecting Stepduino to different compiler

The stepduino is Uno compatible so you should be able to install the bootloader in the same way as the Uno. The Arduino IDE makes that easy, but you do need a programmer of some sort. Plenty of info available on that.

Re: Connecting Stepduino to different compiler

Not familiar with either Flip or XLoader so can't offer much help.
If it says it programmed the target correctly (and I assume also verified it), then maybe you need to look at your sketch. Or start with a simple test sketch to do something very basic on the stepduino just to verify the process.

Re: LCD issues with 3 or more shields stacked.

Also check that the LCD shield does not have any connection from the contrast pin to the header which might be corrupting the contrast setting. It should just have a small potentiometer onboard (no external connection) to adjust this but there are quite a few variations of the LCD shield out there.
