Thread: Gameduino HDMI board launched on crowdsupply

    Gameduino HDMI board launched on crowdsupply

    After having pushed my 9 inch buydisplay RA8875 screens to the limit with my Teensys, I was excited to get an email this morning that the new HDMI FPGA based board from the Gameduino family has been launched on CrowdSupply:
    Gameduino 3X Dazzler

    Can't wait to get my hands on this as unavailability of fast GPU accelerated large (10''+) screens with Teensy / Arduino has been one of the main limiting factors for my projects.

    This shield seems like it has everything you'd want (except 3D and texturemapping), and the FPGA is pretty exciting. It will not ship for some time. Between now and then, there is some more silicon inside the 4.x series that might be of some use to you.

    Teensy 4.x processors have a PXP (pixel pipeline) which is capable of scaling, rotation, and blending. The PXP has its own execution resources, so it doesn't impact CPU availability. It is rarely discussed on these forums, but its capabilities seem quite useful. It doesn't rise to the level of a GPU (won't draw primitives or do lighting.) I think a simple primitive-drawing engine running on the CPU (Bresenham lines, circles, polygons, filling with solid colors or textures) could combine very well with the PXP.

    True, was hoping to see more information on the Teensy 4.0 PXP but in the end having an HDMI option with integrated GPU is just so convenient and with HDMI the choice of screen is endless. The RA8875 based displays are not bad but some of my projects require very low latency info updates on the screen on controller changes and the RA8875 is not that fast.

    My takeaway from the 1060 manual was that the built-in PXP stuff wasn't actually useful unless you were directly driving the output on the LCD interface.
