Last change on this file since 612 was 603, checked in by Krister Nordvall, 4 years ago

Changes:

  • Fixed a bug in Strings.asm from r589 where building the BIOS without MODULE_STRINGS_COMPRESSED would fail. Also removed a redundant CR to save a byte when building without MODULE_STRINGS_COMPRESSED.
  • Optimized the code in MODULE_HOTKEYS to reduce ROM space usage, stack usage and time spent in the user timer tick interrupt handler (1Ch). I hope this will fix the problem with hangs introduced in r599.
