Someone on Twitter, with a straight face, literally just asked me why I didn't bother using a dedicated DAC chip for driving the VGA display.
"They're dirt cheap," he said. Quote-unquote.
Maybe I'm looking in the wrong location, but a high-speed DAC chip averages about $5. A resistor averages about $0.005.
The only time a DAC chip starts to make sense is when the PCB surface area used to *place* the resistors is large enough to cost more than the chips themselves.
I just can't even...
@ddipaola Let me get it working at 🤔 . o O ( ... doing the math ... ) 0.6K, and we'll see how to expand its capabilities from there. ;)
(It ought to be possible to support; BUT, you'll need a different register set to support wider character counters/sizes.)
