Re: Why two mosfets in circuit for "N-MOSFET driver"

Just a suggestion, but maybe because the WS2811 is a current driver device it cannot be guaranteed to reach appropriate logic levels to fully drive the NTD5867.
You could try an email to support@freetronics.com.au and see if they have design details.

Re: External data not reading

In

Code: Select all

dmd.drawString(  0,  0, (t), 3, GRAPHICS_NORMAL );
Looks like (t) is only pointing to a character and you're trying to print a string?

Re: Missing characters from serial input when using DMD2

Sorry but I can't offer much help here as I have not done much with DMD2. You could try limiting your serial while loop to doing nothing but gathering the input characters and putting them into a buffer and see if that has any effect.

Re: Missing characters from serial input when using DMD2

I suspect your sketch is spending too much time in the interrupt updating the DMDs. It will take quite a while to do this with 10 DMDs. Characters will probably be lost during this time.

Re: MQTT really slow to subscribe

setLatchChannelOn() is a procedure defined at line 202 in the code provided in the earlier message so it should be available to you as long as you have the case correct case. NOTE the capital 'C' - you show setLatchchannelOn with a lowercase 'c' in your message and that will not work.

Re: Split screen marquee/scroll

I think you can achieve what you are after by using the DMD2 library - have a play with that one. I have not done a lot with that so can't really help with that.
There is no mod to the DMD library that will do it for you as far as I am aware, but it would certainly be possible to do it.

Re: Split screen marquee/scroll

Did you try your setup with the standard unmodified DMD library using some of the supplied examples? If that works, then there is a problem with the changes. If it still does not work there is probably a problem with your sketch or your hardware setup. Are you using a Uno? If you are still having pr...

Re: Countdown in the center of DMD

Not very familiar with the DMD2 library, but doesn't the TextBox allow you set the vertical position? Would that work for you?
You can then read the height of the font and the display then work out where to place the text box.

Re: How to display the degree icon

It is best to rename your modified font to avoid any confusion as well as adding plenty of comments in the file to show what you have done and why - remember that you can never have too many comments. To rename the font you need to do 3 things: (demo here will use "MY_Droid_Sans_12" for the new name...
