Dazzler with Teensy 4.0

[alfa95139]

I just bought my Dazzler for Teensy, and have a Teensy 4.0 ready to go!
I was wondering if anybody has already some files/examples - even I think everything for the Arduino will just port very nicely for Teensy 4.0

Also, a few days back I saw a small sketch (it was in C, not in Python) used to read the SD card directory and to print its content on the screen.
I cannot find that sketch any longer, can someone please point me to it?

Thanks a bunch!

Yes the standard GD library is tested with the Teensy - we use it here every day with the Teensy 4.0:

Hi Leray,

I have the Teensy 4.1 working really well with the Gameduino 3x Dazzler Here: gameduino2.proboards.com/thread/1065/solar-powered-display-connected-teensy

They do work really well if you ensure you keep the memory usage in check and keep the display list below the maximum amount (think it's 2048).

I found using built in widgets used up a fair amount of the display list, so I use *.png (BITMAP) images instead to build up the display and use masks to get the shapes I want.

Also this is also a great guide for helping you program: www.ftdichip.com/Support/Documents/ProgramGuides/FT800%20Programmers%20Guide.pdf

Hi,

To learn to program with the arduino 2 and 3 library this PDF is more appropriate :
