RGB to HDMI Testers Release #1

This release is a snapshot of the current dev branch.

It may be unstable, so be warned!

Supports both the BBC and Atom hardware versions.

Early Adopter Release #5

Summary of changes:

Pi Firmware:

• Fixed bug affecting test_for_elk()
• Added alternative pixel sampling modes (normal, subsample even, subsample odd, pixel double)
• Added cmdline.txt entry for Oric-1 (tested on Rev's Oric-1)
• Performance optimizations to capture_line_mode7_4bpp.S (Dominic)
• Fix several cppcheck warnings (Dominic)

CPLD:

• No changes, version 2.1 is still the latest version

Early Adopter Release #4

Summary of changes:

Pi Firmware:

• A redesigned (multi-line) menu system that is easier to navigate
• Faster/better auto calibration algorithm in mode 7
• Added "Bob" Deinterlacing algorithm for mode 7
• Added "Advanced Motion Adaptive" Deinterlacing algorithm for mode 7 (CPLDv2 only)
• New delay parameter in sampling menu to fine tune horizontal position (CPLDv2 only)
• HDMI clock calibration (including full Genlock capability to lock source and HDMI Vsync)
• Re-purpose LED1 as a three-state Genlock indicator (off, flash, on)
• Support a wider range of HDMI clock adjustment (within the HDMI 1.0 limits)
• Added a VSync indicator
• Auto Calibration now works with non-standard video timings (e.g. 3D Pool, Labyrinth, Monsters)
• Change of interlace now treated as a mode change
• Configurable key-map to redefine button use
• Buttons now auto repeat (makes changing values easier)
• Improved user feedback during HDMI Clock Calibration
• Improved user feedback during Auto Calibration
• Many assembler code performance optimizations
• Configurable geometries and sampling clocks through geometry menu (*)
• Support for 8-bits/pixel frame buffer (*)
• Added more HDMI modes to config.txt (*)
• Added examples of non-Acorn/BBC systems to cmdline.txt (*)

(*) Features to support non-Acorn/BBC systems

CPLD:

• Add 4-bit delay parameter (that allows fine tuning of horizontal position)
• Start sampling line 8us earlier (to support non-Acorn/BBC systems)
• Version updated to 2.1

Early Adopter Release #3

Summary of changes:

Pi Firmware:

• Added option of Motion Adaptive Deinterlacing in Mode 7 (IanB)
• Added OSD menu for deinterlacing
• Info/Firmware version screen now includes CPLD version
• Fix missed palette change when OSD cleared (in non DEBUG mode)

CPLD:

• Re-centred MODE 7 screen
• Version updated to 1.2

Early Adopter Release #2

Includes features described in the test build.

CPLD (v1.1) includes more robust csync de-glitching

config.txt adds 1024x600 and 800x700 modes

config.txt documents use of scaling_kernel parameter
