@mitu I gave it another shot and moving the line to autostart did the trick! Music still starts and I get to keep the music folder on my usb stick. Thanks!

Thank you for the point to minty pi.

Will post the first images as soon as it‘ in „beta“. But it will be fairly easy to print and build ;) will be in beta somewhere in q1 :D

@nemecyys said in runcommand-onstart.sh pass data to python script:

Because im running this python script every time i run onstart.sh or onend.sh does that mean there will be LOTS of instances of it running?

On normal typical usage, no. The runcommand script calls the onstart one and waits it finish. The way you're invoking your python script in onstart also makes it wait the python script to finish.

Then, from what I'm seeing from the codes, I believe that there won't be lots of instances running.

With a Bash Script:
Would this also be the case?
Would i want to exit the bash after running and achieving the desired result?

There's no need.

*also, any links to some of meleu's coding goodness?

You can find links to some of my scripts on the "useful topics" post (link on my signature). You can find many other useful info there. ;-)

Oh, as @cyperghost said, we usually use this thread to talk about shell scripting.

By the way, you asked above and I'm not sure if you got an answer: the /dev/shm/runcommand.log file is deleted after a shutdown/reboot.

@buzz
Sorry for the long delay - I was prevented from working on this. When I did get around to it though, I was able to use this advice to come up with a solution. Thanks a bunch!

I have reinstaled retropie , and Reicast is ok now.
but now I have another issue,I can't see my Pi in my network -_-' .
BTW , you can close this topic.

@anasazi29 Broadly speaking, here is what you need to do: You need a python script that will watch a GPIO pin (that you have wired to a normally open switch like an arcade button--other wire to ground) such that when the button is pressed, the script sends a keypress. The key you send (suggestion: "ESC") would have to be picked up by the emulator as EXIT. So, you will have to go into your retroarch.cfg file, disable the hotkey function, and set the EXIT function to "ESC".

I know of a few ways this has been done in the past. One of the more popular is to use the adafruit Retrogame software. This basically takes care of the scripting process and leaves it up to you to configure what keys the GPIO pins trigger. Some folks use ONLY this solution for input control.

I also like mholgatem's GPIOneer which does the same thing, but uses a more elegant interactive configuration, then a web interface once it is setup. It is also easy to configure combo keys and to send full commands (I use it to send commands to increase and decrease master volume).

@valerino Looking forward to try this one, and help on everything that I can!

It's working!

I reapplied the Raphnet kernel patch. The CPU is once again showing as BCM2835, but my screen's output is fixed! It looks like the 20170303 version of the kernel fixed the issue.

I'm really going to think twice about updating the software on my now working Super Famicom Pi.

I could narrow the problem down a little bit. When the db9_GPIO_RPI driver is not loaded and i try to unload it, I get:

"modprobe: FATAL: Module db9_gpio_rpi is not in kernel"

that makes sense but I tried to avoid that with try/except. Seems it does not work. Any idea why?

Ah ok thank you. So basicly i neet to change the command to

subprocess.call("modprobe --first-time -r db9_gpio_rpi", shell=True)

and import the subprocess?!

@flop I'll attempt to wire the pi with a fan and a transistor going to pin 12 (GPIO 18) and I'll report back with findings.

@Capt_MorganCreek Hey!
Thank you very much for the file and the Help!
I had to change a little bit in the Script and use now uinput from uinput.
I ran into Problems with Dependencies... basically I haven't read thoroughly enough...
Everything else in the Script is the same.
Software works and the Buttons also... but! I have to make a new Plan on the Hardware itself.
It turned out that the Way I wantet to build the entire Thing does not work. It just does not fit...
Will have to see when I will have enough Time again to make a new Plan...

Big Thanks for the Help!

Thanks for the help. That did solve it for running it myself but the python script still failed. I get

/opt/retropie/configs/all/autostart.sh: line 1: 3353 Terminated emulationstation
tput: unknown terminal "unknown"
'unknown': I need something more specific.
Error opening terminal: unknown.
Traceback (most recent call last):
File "/opt/retropie/supplementary/runcommand/joy2key.py", line 42, in <module>
curses.setupterm()
_curses.error: setupterm: could not find terminal

Then emulationstation proceeds to launch again.

In the end I got everything working by going back to RetroPie v4.0.2. I really do not care about having the latest version for this one as it is more of a novelty item than anything since I can launch games with cartridges.

You may be able to launch your python script from the runcommand-onstart script and reset it with the runcommand-onend script.

See: https://retropie.org.uk/docs/Runcommand/#runcommand-onstart-and-runcommand-onend-scripts

@Drakaen391 Yes, I am aware that scripts can launch scripts and do quite often. The idea of a single line bash script just to execute a python script is pretty silly though.

The matter is closed though. The devs aren't interested in the idea which is their right.

@BuZz Thanks. It was worth a shot.

I didn't see anything on Attract-Mode's documentation about it there either. :(

@obsidianspider bro, that is so cool. Now I gotta try it too.
