v18

Added by foft almost 7 years ago

I've been trying out some other parts of the hardware in advance of the new boards. The clock generator and the i2c video support are confirmed as working. Also the sd card detection line.

I've put these to initial use in v18 as follows:
  • Requests DDC data over VGA and HDMI and shows if they are detected as connected in video settings.
  • Handles SD card being changed
  • Handles SD card not being present on boot. In this case starts as 320KB compy 1x speed NTSC. Attempts basic video connection detection, HDMI first, then VGA, then falls back to 15KHz RGB.
  • Increased ZPU rom from 32KB to 40KB.
