Bittboy builds?

[purelygrey]

Hello! I use LGPT on Powkiddy V90 and I use the Bittboy build for it. I build the 1.3o_2 myself and I've been running my projects on it for a bit and everything seems to work just fine.

What's required to bring Bittboy builds back? I've read they were dropped because of lack of testers, what kind of testing is needed?

Also to everyone involved -- fantastic job!

[djdiskmachine]

Hey thanks for showing some love to the Pig! =)
I can attach a Bittboy build later this evening if you care to try it out =)

[djdiskmachine]

Here you go.
Things to keep an eye out for is save as functionality which should be OK with the latest build.

If you have any recommendations for mappings, config that makes it run nicer please attach as a reply here and I'll include them in the official build. I don't have a device to test it myself. =)

[djdiskmachine]

Omg I'm so sorry I didn't read you already built it yourself, way to go!
If you feel it works good I can just update the release with this as well ^_^

The lack of testers was due to not being aware of anyone that could find any issues for this specific platform and describe steps on how to reproduce, very happy to have you :)
Please join the Discord if you want to discuss further. Cheers!

It's alright, thank you though :) I tested Save As on my tracks, it works fine, so far I couldn't break this build in any way, should be safe enough to include in the release. Will do my best to report any issues from now on.

As for mappings/etc the defaults should be fine for now.

I actually have a pretty nice setup on the V90 (it has a "function" button which I use as shoulder button along with select) but it's hacky and I haven't tested the non-hacky way on the latest firmware. Even after I figure that out it'd be better to put it on a wiki or make a separate build for it since the Bittboy build also should work for Q90 (which is horizontal) and, well, Bittboy :D

Sorry not really a Discord guy, but I might swing by sometime later. Thanks again!

[djdiskmachine]

Jolly good, thanks a lot for checking in and trying it out 🥰
Alright you do you, Discord sure isn't for everyone :)
Nice work with the mapping, that sounds comfortable :)

I'll try to do some more work on the coding side in a few weeks when I feel up to it again, right now I'm enjoying making music with 🐷
All the best!

For Powkiddy V90 I made a package without building.
I used the binaries from RG35xx (lgpt and j2k.so).
I had to put them in root folder (outside of bin), to recognize the samplelib folder.
LittleGPTracker.sh moved there too.
Then updated the path in LittleGPTracker.sh : progdir=$(dirname "$0")
This is my config.xml with V90 key mappings (I prefer A-B reversed):



<KEY_A value="key:0:left alt" />
<KEY_B value="key:0:left ctrl" />
<KEY_LEFT value="key:0:left" />
<KEY_RIGHT value="key:0:right" />
<KEY_DOWN value="key:0:down" />
<KEY_UP value="key:0:up" />
<KEY_LSHOULDER value="key:0:tab" />
<KEY_RSHOULDER value="key:0:backspace" />
<KEY_START value="key:0:return" />

Hi guys, not a discord person either but I am using LGPT on the v90. Not sure which build I have that works but it sure is the last one. I found mine on an SD image from a youtube video and changed stuff here and there to make it work on my 1.3.3 cfw.

In any case, I'll try this new one, thanks a lot! I agree it would be nice if the v90 had its official build. Happy to report anything if that helps.

[ploupipoulpi]

What an improvement from the older version. Congratulations on the good work, and thanks.
I didn't have to do anything besides a config xml for folders and a&b swapping.
I tried it on my stable CFW 1.3.3 on a v90, will try it on the 2.0.0 soon.

I'll come back with more feedback after I spend some time using and abusing it.
Once again, a thousand thanks for keeping this alive and making it even better.

[djdiskmachine]

Hello!
I'm setting up workflows for automated builds, please attach any configs that you'd like included with Bittboy builds and I'll add them to the workflows. :)
Cheers!

[purelygrey]

I think the defaults are fine for now. There's enough latency to make it unusable for DJing but I couldn't make it better through configuration on the Bittboy build, not sure why. I love using menu button for screen navigation, it's so much better than going for shoulder buttons all the time, however the setup I use doesn't really work out of the box with the V90 CFW due to menu button hotkey combinations not registering, if that gets fixed someday I'll do a PR separately or something else. Maybe @ploupipoulpi has some ideas (glad to see another v90 enjoyer :-) )

[ploupipoulpi]

for now I only see the config switching a and b for the v90 that would be nice.
the different button layouts are there: TriForceX/MiyooCFW#274 if that's helpful

For navigation I already have muscle memory from LSDJ with select+dpad and I even prefer using the shoulder button on the v90 to the point that I might remap R1 to select for LSDJ. I wouldn't personally use the menu button for that also because I don't like its clickyness on the v90. Although I'm interested in your hacky way purelygrey, for science.
Other than that, it works out of the box if the folders are in the right place.

I just finished a shell/python script for color theme selection at startup but I need more themes with the new available colors and I realized that I forgot the row number selection so I'll add that as well.

I'm adding a "music" tab in gmenu2x on my v90 with things like GMU, LGPT and direct links to LDSJ and other chiptune roms, if you have any logo or any visual besides the pixelated piggy let me know, if you're interested in that setup I can share what I'm using.

I haven't finished the "one text file" manual but if I can finish it soon we could add that, as it can then be made available in gmenu on the LGPT link (Y for manual on a link if it exists), that would be nice in a v90 build for Miyoo CFW.
I also tried to make something sexier than a text file but failed (for now).

Finally, it would be great if an official LGPT build was listed in the the Miyoo CFW ports.

I put the LGPT directory in /mnt/apps with everything in it, but for sample management, one might prefer have the project and sample directories directly on the main. I don't know what the best "default" would be.

In the package we could also add the link for Gmenu2x

title=LGPT
description=Little Piggy
exec=/mnt/apps/LGPT/lgpt-bittboy.elf
manual=/mnt/apps/LGPT/lgptmanual.txt

Thanks again for all the work, I'm moving pretty slow on this but making progress. I hope I can contribute a little to the piggy community.

Here goes, for science! @djdiskmachine you can disregard everything below

Same here about lsdj, I'd actually prefer to have a single select button for everything, but that only works on vertical handhelds. And yeah you're right I completely forgot that I modded my V90 with a piece of foam to dampen the annoying menu button microswitch 😀 it's an easy fix, get some EVA or some sort of soft foam and put it inbetween the switch and the button, makes it a lot better even if you won't use it for LGPT

I haven't updated to the official 2.0.0 release yet, I used the betaalpha when it was around. I only use my V90 for Piggy, mine boots straight to LGPT and shutdowns on exit. The 2.0.0 beta made it possible to turn off constant disk checks on unclean shutdown, and I haven't had any problems with flipping a switch yet, it should be pretty safe, I don't think Piggy writes to disk unless you are loading a sample/saving the project or if logging is turned on. It feels very gameboy-ish to just flick a switch to turn it off.

/autoexec.sh (I have LGPT files in the root of the MAIN partition, sleep 0.5 is a hack so the v90 has enough time to redraw the screen after bootlogo, cd'ing to mnt is needed for Piggy to see the folders in MAIN):

#!/bin/bash
sleep 0.5

cd mnt
./lgpt.elf &

program_pid=$!

while kill -0 "$program_pid" >/dev/null 2>&1; do
   sleep 1
done

poweroff

However as I mentioned Menu button is used as a system hotkey modifier in MiyooCFW and there's no fallthrough for it, I mean even when system hotkeys are turned off through a config file they do not register at all in LGPT, they just do nothing. A dirty fix for that is to set device type to Q90 instead of V90, so the system hotkey is on R2, and menu button is free for application hotkeys. Didn't have any problems with that as well so far

Part of config.xml with folder paths and menu button (Q90 firmware):

<ROOTFOLDER value="/mnt/PROJECTS"/>
<SAMPLELIB value="/mnt/SAMPLES"/>

<KEY_UP value="key:0:up" />
<KEY_DOWN value="key:0:down" />
<KEY_LEFT value="key:0:left" />
<KEY_RIGHT value="key:0:right" />
<KEY_A value="key:0:left alt" />
<KEY_B value="key:0:left ctrl" />
<KEY_LSHOULDER value="key:0:escape" />
<KEY_RSHOULDER value="key:0:right alt" />
<KEY_START value="key:0:return" />

Hi guys, @purelygrey @djdiskmachine
I completed the script for theme selection.
I hardcoded the controls in python, and it works fine on the v90

Anyone willing to test in on a v90 (I haven't tried it on the 1.3.3, only on 2.0 beta2) or another device?
I probably need to adapt it to test for device and change controls.
Currently it captures "A or Start", "B" and the DPAD. For the v90 A is LALT and B LCTRL, start is "Enter".

How it works: you create a folder named "themes" in which you put individual themes XML with the following :

You can have many different themes in the folder, it's going to list them based on file name.

Script will display a menu that allows to select a theme based on its name with up/down and to modify the "Altrownumber" with left/right. Default sets the value to what is in the theme xml.

Selecting a theme and pressing A applies the theme to the config.xml

Only caveat is that it is pretty important to respect the syntax exactly (space included) in the config.xml and individual themes xml.

If you want to test this script please let me know and I'll prepare a zip with everything inside.
If you want me to adapt the script for a specific device, let me know and I can look it up but I'll need someone to test it.
It will run for sure on any device under Miyoo CFW firmware (again, only 2.0 beta2 tested currently) with maybe the need to modify key detection based on device model.

Now making themes can be a pain with the new colors, so I'm updating the theme creator page ( http://poyo.co/lgpt/ don't know the owner, downloaded the code and messed with it locally). My current local version has all the new colors, but they're not set up to display in the example yet. It will allow the export of properly formatted individual themes for the theme selector script.

I'll have a local working version soon, however @djdiskmachine can you confirm exactly what the colors do now between hicolor, cursorcolor, and songview ones? It would be easier for me to update the tool.

Here's the code for the theme selection script for the v90, still need to clean a few things up but it's enough for testing purposes (note: half of the credit goes to chatGPT which was very helpful for making this work):

#!/bin/busybox sh

# Initialize variables
themes_folder="/mnt/apps/LGPT/themes"
config_file="/mnt/apps/LGPT/bin/config.xml"

# Check if themes directory exists
if [ ! -d "$themes_folder" ]; then
    echo "Themes directory not found: $themes_folder"
    exit 1
fi

theme_files=$(ls $themes_folder/*.xml 2>/dev/null)
if [ -z "$theme_files" ]; then
    echo "No theme files found in: $themes_folder"
    exit 1
fi

for theme_file in $theme_files; do
    theme_name=$(basename "$theme_file" .xml)

the piggy themer for which I need confirmation to set the new colors on the example on the right side

[ploupipoulpi]

I think I found them all.
Is it me or rowcolor2 and 1 are reversed?
I intentionally used ugly colors to make it easier so see, this is not my taste in colors :D
