1. PSRAM based Anti-Aliased GUI --> Now 16bpp

   Just merged Chip's PSRAM driver and Anti-Aliased line drawing code with McuFont in Flexprop. Think have the beginning of a 24bpp PSRAM based GUI. Currently outputting over HDMI. Here's a font sample with an anti-aliased line drawn through it:

3. P2 HDMI splash screen then text mode

   Is anyone working on code that can display a BMP to HDMI and then change to display active data? I've included the HDMI demo BMP code and it doesn't leave much room for to much more code in memory after loading the BMP. I see the BMP file is comment out as I was seeing how much memory it used. Thanks for any information.

4. DVI/HDMI with increased blanking?

   I don't have the Eval digital video board hence this question. Is it possible to use 300MHz sysclk to display 640x480 by increasing horizontal blanking and total from 160 and 800 to 312 or 313 and 952 or 953, respectively? Vtotal unchanged at 525 lines.

   That's a half-truth. Native HDMI/DVI devices (presumably also DP) will just lock onto whatever you give them. But if you e.g. put a VGA converter box in the middle, it will copy the timing from the input 1:1, which can be far beyond the range of what any normal monitor can adjust to. Though that's mostly a limitation of…

   252 has far more divisors (/2, /3, /4, /6, /7, /9/, /12, ...) than 250, which makes 252 MHz perfect if sub-clocks of say 3.5, 4, 6 or 7 MHz are wanted. Also, 252 MHz is a standard DVI/HDMI frequency, again preferable for HDMI audio.

   Neat idea. If you have room somewhere eg. down near your potential HDMI connector (full size or micro?), a spare SOP8 footprint for devices with 6 free IO available could be useful for anyone interested in soldering in some optional additional flash or PSRAM device etc, as such spare memory is always useful for video, or…
