So its looking like I want to do the mausberry varient if these power mods, which varient are people using mostly to get what I'm after tho?
https://mausberry-circuits.myshopify.com/products/shutdown-circuit-use-your-own-switch

direct-plug micro-USB, 2-pin spring terminal header, or the versions with a USB female plug?

I'm still not 100% certain how this works but it looks like the switch only controls either the reset or power switch? If that's the case does the power switch still power everything directly?

What I'm thinking is this correct me if I'm wrong?

Power switch = hard on off power (no script for safe shut down)

Reset switch = mausberry switch with script that if in emulator and pressed quits the emulator and if not in emulator and is pressed runs script for safe reset?

@dankcushions said in Design dilemma for retro arcade machine:

plus of course, if you play any console games the 'insert coin' button is by default also the 'select' button, which is used in SNES, PSX, etc.

No plans to play any console games. I was always a C64/Amiga fan, but I emulate these on my PC 'cause it's a more suitable environment than a arcade machine. The one game I wouldn't mind from a console would be Alex the Kid from the Master System (I believe).

Thanks for your input

Hi everyone

@nickstr138 I have created a "driver" for this, check this out :

Hi,
Yes in the end I decided to get a snes-style USB controller, and it seems to be working a treat!
Sorry for the delay in replying...

@mitu said in DB9/Gamecon installation error:

I don't, didn't work with Berryboot, only normal images.

Thanks for the help, I'll look for a way to convert an image.

Please give more details about your system - https://retropie.org.uk/forum/topic/3/read-this-first.

Alright thank you.

@mitu Thanks. It works now.

I think the first step would be to test if I can capture audio natively before I pass it through to GPIO.

I've narrowed it down to wanting to use the alsa sound driver. I want to be able to hear the sound from my speakers while it's being captured which is looking like I'll need to use a loopback device. Eg snd-aloop

I'll update this post when I have more details but I've gotten so far as sorting dependencies and just need the proper configs for /etc/.asound.conf

@haemogoblin said in Rigging reset and shutdown buttons:

I think I now have the power button in the bag, using a Pimoroni on/off shim.

I've written a small tutorial for the OnOff SHIM here

@zerojay Thanks. Good to know.

Hi,

I have followed much of the same process as on here, I have up/down/left/right/a/b/x/y all working ok.

Start and select don't work however. In the config file I have the following:

SELECT 6 # 'Select button'
START 16 # 'Start button'

I noticed in the list of commands does not include 'start' and 'select' (i looked at the kerTable. file referred to on adafruit tutorial) so maybe it should be SPACE and ENTER, I tried this but still does not work in emulationstation or when playing a game.

Any ideas?

I am just using arcade buttons and a joystick.

Just to check, does the part after the # matter? I thought this was just a reference in the code to the person reading it so they knew what that button/PIN did.

@retro_pi if you read my post it’s in there. If you have specific questions I will be happy to answer them.

Retropie detects 2 gamepads when I connect the Teensy with the 2 analog sticks, but I can't configure any input when I move the PSP sticks. Any idea? :/

Here is how to set Long press and Short press function. I added on my reset ROM button a long press feature that resets the entire system:

Create a script that will be executed at long press
nano /home/pi/switch.sh

Paste the below code and save using CTRL + X, Y

#!/bin/bash sudo reboot

Make it executable:
chmod +x /home/pi/switch.sh

Edit the code in the first mentioned post resetbutton.py:

nano /home/pi/scripts/resetbutton.py

Replace all text with the below code, save using CTRL + X, Y: #!/usr/bin/python import RPi.GPIO as GPIO import time import os # we will use the pin numbering to match the pins on the Pi, instead of the # GPIO pin outs (makes it easier to keep track of things) GPIO.setmode(GPIO.BOARD) GPIO.setup(16, GPIO.IN) seq_cust = 0 tim_cust = 0 # check to see if button has been pushed try: while True: if GPIO.input(16)==0: tim_cust = 0 if seq_cust > 0: os.system("sudo /home/pi/exit.sh") # Short press action seq_cust = 0 time.sleep(1) else: seq_cust = 0 else: tim_cust = tim_cust + 1 time.sleep(.01) if tim_cust >= 200: # Time for long press >= x os.system("sudo /home/pi/switch.sh") # Long press action tim_cust = 0 time.sleep(1) else: seq_cust = 1 finally: GPIO.cleanup()

I used 0.01 seconds to eliminate delay in button press.
At 200 should result in ~2 seconds.

You can put your own script in switch.sh
Also the script supports more than 2 actions per button with a bit of tweak.

Enjoy ;)

@azamoth
As @caver01 told you there are several ways... and your display just needs a few Pins as told....

If nothing else helps use MCP23008 or MCP23017 gpio expanders and connect to I2C-bus. But please don't ask me how to do this. Never used that :)
