20240213_e630d36f Release

Introduction

This is a stable release (from the master branch).

(the previous stable release was 17th May 2023)

This release rolls up the Ian's changes from Beta59 to Beta64 (inclusive)

Format or wipe the SD card before upgrading, do not overwrite as that can result in profile and palette errors.

Beta 64 changes

• Fix monitor power up issue
• Fix some scaling issues
• Remove obsolete profiles

Beta 63 changes

• Fix issues with low cost HDMI audio embedder
• Add some lumacode profiles including for TMS9918A / TMS9928A / TMS9929A based systems like the TI-99/4a
• Add support for 15Khz HDMI output (720x288 & 720x240)
• Update Commodore PET profiles
• Add quickstart help
• Fix favourites bug

Beta 62 changes

• Fix some issues with sync detection and measurement
• Fix GPIO pull up/down on Pi 4
• Add some new genlock options
• Increase some settle times on GPIO reading
• Add Commodore 64 VIC II R56A sub-profile
• Add VIC20 NTSC lumacode sub-profile
• Add Triumph Adler PC8 profile
• Add alternative RGB lumacode profiles.

Beta 61 changes

Major new features:

1. A "Create Custom Profile" menu
   This makes it much easier to create profiles for unsupported systems
   There is built in help in the info menu and also in the menu itself
   (This will eventually be expanded upon in the wiki)

2. Auto detect if the monitor supports HDMI protocols or DVI protocols and switch automatically.
   This was previously a manual only setting in the main menu which defaulted to DVI for all monitors
   This usually worked but would produce wrong colours on some capture devices and 4K monitors which didn't support the old DVI protocol.
   Also if a HDMI audio embedder was used, that would normally only work in HDMI mode.
   The auto detection can be disabled and a manual selection made in the settings menu
   Please report any issues such as blank screens if your monitor worked with previous versions.

3. Add 4K @ 50/60Hz support for Pi 4 only.
   This will be auto detected if a Pi 4 is plugged into a 4K monitor
   Other Pi models only support 4K @25/30Hz so they will default to 1080p @50/60Hz when plugged into a 4K monitor but you can still manually select the 4K @25/30Hz resolution.

Other changes:

• Fix scalines not working on c64.
• Add support for PAL artifacts on c0pperdragon c64 YUV adapter.
• Add variable level scanline support to Atari 800 lumacode.
• Fix flashing screen issues with Atari 2600.
• Add frame drop mode for 25/30Hz motion.
• Add Ti presenter profiles (NTSC only).
• Support Atari 800 hybrid configurations (swapped PAL/NTSC Antics etc)
• Fix dragon profile
• Various minor bug fixes and cosmetic improvements.Beta 61 test release

Beta60 changes

• Add Mac SE profile
• Add Spectrum 48K VLA82 profile
• Fix scanlines not working on Atari 800 lumacode (note black scanlines only at the moment)
• Add Atari 2600 lumacode profile
• Update various profiles

Beta59 changes

• Improve support for Commodore 128 80 column (CGA type) mode with profiles for VDCmania demos
• Add Commodore 128 lumacode profile
• Add support for Atari 800 lumacode and Improve Atari palette generation
• Add support for VIC20 lumacode (50Hz only at the moment)
• Add PAL artifact (colour blending) on Commodore 64 & 128 lumacode (use long press of SW2 to toggle)

• Note the 640x256 and 1280x256 cannot be auto selected and must be toggled with SW3
• Update various existing profiles.

20230517_eb620884 Release

Introduction

This is a stable release (from the master branch).

(the previous stable release was 21st December 2022)

New Features

This release has a major new feature, a "Select Profile" menu option that makes changing profile a lot easier.
After selecting the option you are presented with a list of manufacturers and after choosing one you are then presented with all profiles for that manufacturer, including profiles for the other CPLD versions as well as the current CPLD.

Profiles that require a different CPLD firmware are prefixed by (BBC), (RGB) or (YUV) as appropriate.

Selecting a profile with no prefix will immediately switch to that profile

Selecting a profile with a prefix will reprogram the CPLD, reboot and select that profile.

There is also a recently used option that keeps a record of the last ten profiles selected.

Other Changes

Add support for c0pperdragon's new Commodore 64 VIC II plug in adapter which outputs a special 'lumacode' signal on the modulator Phono output that RGBtoHDMI can decode into bit perfect HDMI.

Auto detection for 2560x1440 monitors, (previously the Pi would not auto detect this resolution)

Some support for 4K monitors:
The pi zeros don't support 4K @50/60Hz so by default RGBtoHDMI will select 1080p@50/60Hz as appropriate when connected to a 4K monitor. This is not ideal as the monitor will interpolate that to 4K resulting in soft edges.
However there are two manual modes to try:

• Full_4K@25/30Hz - This will give 4K resolution but at half frame rate (which the zero supports) although every other frame will be dropped giving a 'film effect' on smooth motion.
• Half_4K 1920x2160@50/60Hz - This is a compromise resolution which is the same height as 4K but half the width and again the Zero can generate that. This results in integer scaling vertically and interpolated scaling horizontally but as it is a very non standard mode, a lot of monitors and TVs may not support it and give a blank screen etc. Also it may be displayed as a narrow image in which case you need to change the monitor's scaling to fill the screen (not RGBtoHDMI scaling).

Soft Reset
Pressing SW1 and SW3 together will cause a reboot and this can be useful if the board is plugged into a Pi that doesn't have any reset mods made to it.

No CPLD detection
If you boot up the software with no CPLD board plugged in you will get an error message and the main menu displayed and this can be useful to confirm the software is installed and booting properly if you have a problem when the CPLD is plugged in.

Help Menus
There are several help pages in the info menu describing button functions, calibration, NTSC artifacts and common problems plus where to download updates.

Supported Profile List
There is a menu option in the info menu to save supported profile list for current hardware as "Profile_List.txt" for easy reference. (This list will be different depending on analog or digital interface)

Add warning about pre-programmed CPLDs to the CPLD recovery menu. (Using CPLDs with other firmware already installed can cause reprogramming problems and this describes the workaround)

Add 8 level mono palette

Add support for line doubled capture

Sync detection moved to GPU (Improves performance at high pixel clock rates)

Fix issues stopping very high resolution sources from being captured (864x1024@60Hz 3BPP has been tested)

Fix sync polarity detection when auto sub-profile switching

Add Commodore 64 lumacode profile (see above)
Add Exidy Sorcerer profile
Add NEC PC 16-01 profile
Add Meldas CNC9 profile
Add Amiga 3000 profile
Add Atari ST (No Blanking) profile (for earlier adapter board)
