does the command spit out error codes as we can use them...

pi@raspberrypi:~ $ ledspicerd -d
Program terminated by error: Empty devices section

@hopwon If no ones suggested it yet, advanceMame has a scripting system that can take actions on emulated external outputs such as Led's, and other hardware...

https://www.advancemame.it/doc-script here is the documentation for the scripting and outputs.

hopwon

@Folly The computer is telling the truth, you need to populate the /etc/ledspicerd.conf file :)

But this is fantastic, I will have a go at compiling and then give LR-mame a go. I looked at various scripting options last night and while I can create a counter which will increment every time the credit button is pressed, I could not find a way to decrement it, so I went to bed!

@hopwon

On which hardware do you run retropie ?
lr-mame can be installed from binary when using rpi.

Tell me, what script did you make to count the inserted coins and do you use a joystick or keyboard ?

First post:

... I am using LEDSpicer on RPI4.

A bit nasty but:

I used inputseeker running in background to grep for a credit button being pressed on(6=P1, 7=P2 in my case) and when it successfully finds a 6 or 7 it increments a counter +1.
You can do it with awk also but I got tired and when to bed :)

Installing it now

@hopwon

I will look at ledspicer with inputseeker again.
Seem a really nice package but I have to take some time to dig into it.
Hopefully I will grasp it.

@hopwon

I uninstalled my previous install of LEDspice.

This I what I did :

cd ~/Downloads/LEDSpicer-development/
./autogen.sh
./configure --prefix=/usr --sysconfdir=/etc --enable-raspberrypi 
make
sudo make install
sudo usermod -a -G users pi #replace user with your username
sudo usermod -a -G input pi #replace user with your username
sudo cp /usr/share/doc/ledspicer/examples/21-ledspicer.rules /etc/udev/rules.d/
sudo chmod 744 /etc/udev/rules.d/21-ledspicer.rules
sudo udevadm control --reload-rules && sudo udevadm trigger
sudo cp /usr/share/doc/ledspicer/examples/ledspicer.conf /etc
ledspicerd -v
ledspicerd -d
sudo ledspicerd -d #seems to be the way to go with RaspberryPi

Running with -d gives :
Program terminated by error: Empty devices section

Added the controller name in /etc/ledspicer.conf :

	<devices
		name="RaspberryPi"
    		boardId="1"
>
	</devices>

or

	<devices>
		name="RaspberryPi"
    		boardId="1"
	</devices>

Still no dice.

Any help would be appreciated.

@Folly You need to manually create your ledspicer.conf, I've attached mine to give you some idea (sorry admins no pastebin!), But basically the file maps pins #'s on your LED controller to an "Element", you can then create groups of Elements and address either the group or Element...

FYI On this controller I have 2 x Joystick + Trackball, each player has 8 buttons, plus start, credit, hotkey and exit.

Make sure when you are starting for the first time, run the daemon in foreground (-f) as it is the best way to troubleshoot. Its quite verbose in its output so if there is a problem you should get a good indication of exactly what it is.

Folly

@hopwon

Thanks, will have a look when I am using my pi.

hopwon

@Folly So I managed to get the command line options passed to lr-mame based on the info you provided. I can now see that (I am using Missile Command as a test), led0=0, led1=0, led0=1 led1=1, repeating in the console for any button press.
This tells me (I think) that mame is making two led's flash and thats it. No specific output regarding credit or I could be wrong.

From runcommand.log using -output console

led0 = 1
led0 = 0
led0 = 1
led0 = 0
led0 = 1
led0 = 0
led0 = 1
led0 = 0
led0 = 1
led1 = 1
led1 = 0
led0 = 0

These represent a button press, I think one press = 4 log entries

Folly

@hopwon

Yes indeed that is correct.

It's jsut how the original hardware worked and that is implemented in mame.
It's basically the same with the galaga example I used before, only here you have to add 2 credits for 1 player and 4 credits for 2 players.

What you want is not implemented in mame so you need to get the information in an other way just like you did with inputseeker.
I tested that and indeed reading event becomes very easy but you need to add a whole script for doing stuff with that information.

I see the problem getting some uniform data for every game it seems a bit different.
Basically it could mean that for every game you need to make a script.

If you want more advanced ways you could look at mame lua plugin scripts.
With that you might be able to extract data in a different / better way.
FYI I used them for tests but I never wrote them.

hopwon

@Folly @MeduZaPaT talks about doing the part to make credit flash here:

link text

If there was a way to set a counter or write to an output, then that's the solution...

Folly

@hopwon

Ok, I used your ledspicer.conf and customised it for use with RaspberryPi (GPIO).
For error sake I made all red, green and blue use the same pin (red=4, green=5 and blue=6) and added an empty profile which is explained over here.

Now I don't get errors anymore when running :

ledspicerd -d

Then I tried :

ledspicerd -f

That gave me :

2023-09-21 21:23:41 initCheckPermitted: 
+---------------------------------------------------------+
|Sorry, you don't have permission to run this program.    |
|Try running as root, e.g. precede the command with sudo. |
+---------------------------------------------------------+
Program terminated by error: Failed to initialized Raspberry PI GPIO

So now I know RaspberryPi needs running with sudo, like this :

sudo ledspicerd -f

I might have to check ledspicer.conf again for correct values and then I have to add some game profiles.
Would like to check first if the mame "-output network" is detected without using emulationstation.

sudo ledspicerd -f should do that trick right ?

Will have look later again.

hopwon

@Folly the -f option runs in foreground so yes, you should see something...

Folly

@hopwon said in Syncing button leds with gameplay:

Missed that part.
No they aren't really button presses.
On the other end you could see it that way but inserting a coin while playing the game does nothing.
Taking galaga as example, it's that led0 goes on and off after inserting a coin and when the start button is not pressed yet and not playing the game.
For missile that is 2 coins (led0) and 4 coins(led1).

Folly

@hopwon

Was able to test the led on GPIO pin 4 with this :

pi@raspberrypi:~ $ sudo ledspicerd -l
Test LEDs (q to quit)

Select a Led (r to reset, q to quit):
4

Select a Led (r to reset, q to quit):
r

So basically ledspicer is working.
Have to look at the game profiles now.

It seems very hard to understand the docs and how everything actually works ;-(

I am struggling with creating a single game input xml in /usr/share/ledspicer/profiles/arcade.
I added galaga in /usr/share/ledspicer/profiles/profile_arcade.xml like this :

<?xml version="1.0" encoding="UTF-8"?>
<LEDSpicer
	version="1.0"
	type="Profile"
	backgroundColor="Black"
>
	<inputs>
		<input name="galaga"/>
	</inputs>
</LEDSpicer>

I tried to begin with the example from here.
Though I have to edit the file somehow as it is not accepted.
Do you have an example for me ?
Or, do you know what to edit ?

I read over here that you can also use a "craftProfiles" option for multiple games.
"LEDSpicer will attempt to use the pre-scraped data from mame (gameData.xml) along with controls.ini (if available) and colors.ini (if available) to set lighting based on the games control scheme. So... one profile_arcade.xml file to manage thousands of roms."

They also use the emitter part.
Is that nessesary to use ?
