A lot of the video game hardware in the late 70’s/early 80’s didn’t have a buffer to “draw” into. The Atari 2600 had (I think) 128 bytes of ram, to draw the screen, developers had to time their code to be in sync with the electron beam raster to draw!</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>There is a project on the web somewhere where a guy made a video game, with VGA output, sounds and game controller input on an AVR chip, a truly impressive feat.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><div style='mso-element:para-border-div;border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal style='border:none;padding:0in'><b>From: </b><a href="mailto:triembed@triembed.org">Alex Davis via TriEmbed</a><br><b>Sent: </b>Wednesday, April 22, 2020 3:19 PM<br><b>To: </b><a href="mailto:triembed@triembed.org">triembed@triembed.org</a><br><b>Subject: </b>Re: [TriEmbed] TriEmbed Digest, Vol 83, Issue 19</p></div><p class=MsoNormal><o:p> </o:p></p></div></body></html><br />> >> Also, since you?re defining the array at global scope, the size of it <br />> >> must be a compile time const-expression anyways, so you wouldn?t even <br />> >> need dynamic memory allocation.<br /><br />it's not going to work (in the 96K RAM of a Due, anyway):<br />arm-none-eabi-gcc/4.8.3-2014q1/bin/../lib/gcc/arm-none-eabi/4.8.3/../../../../arm-none-eabi/bin/ld: address 0x20096900 of /tmp/arduino_build_252939/simple-wireframe.ino.elf section `.bss' is not within region `ram'<br /><br />Womp womp!
