Re: DMD2 Custom pin

KevLeo94, how did you go? Was that your problem or was it just a typo when you entered the code?

Re: DMD2 Custom pin

Haven't looked too deeply yet, but have a good look at your #define statements for OEpin and Rpin - both are defined as A0. Might be a good place to start.
And please use the code markers </> in future when you insert code in a post.

Re: DMD2 Custom pin

Maybe post your sketch so others can see what you are trying to do.
Please note that DMD2 is only a beta and not really supported as the original author has moved on. It does have some good points, but also has some shortcomings.
And not a good idea to get PCBs made before you prove your design.

Re: Unable to see port - Mac Mojave

Obviously you are going to need the appropriate driver - you won't get anywhere without that. You could start here.

Setting up a new ATmena328P

If you obtain a new ATmega328P it will not generally work in an Arduino or programme via a programmer such as the USBasp using the Arduino environment without some pre-configuration. Not all the default settings in a new device are what is used in a Uno. This is an attempt to explain what needs to b...

Re: how do you scroll text from far right to left by pixel column properly?

I suspect this is a problem with the DMD2 library. It does not handle scrolling text (marquee) very well with multiple DMDs. You might have greater success with the DMD library. It will not be difficult to give it a try and see how you go. But you need to be aware that each DMD takes time to update ...

Re: EtherTen PoE

You do not provide enough details to allow people to offer much help. - no idea what PoE board you are using - no idea of what is actually getting hot - no idea of how you have them set up - does the problem stay with the PoE board if you swap them over? - have you double-checked all your wiring? - ...

Re: I want to share an interesting information for you

You did not state which Arduino, so I will assume a Uno. The on-board regulator has maximum current of 1Amp, so that is the absolute limit. However there are other factors here: - the limit will be reduced by the power required by the on-board circuitry, so about 900mAmps - the regulator will almost...

Re: Can the RX433 shield be used to decode Directv RC 73 remote

Haven't heard of anyone doing this. I think you would have to do your own decoding which may be a challenge. Maybe if you could get hold of the receiver/decoder from an old set it might make your task easier. Do they even run at the same frequency? The 433mHz band covers a range of frequencies. Also...
