Hello, we recently identified a bug in the ControlBlock driver. I am very sorry for that! Your observations see to match the symptoms caused by that. We released an update yesterday and that should also fix your problems.

@stoney66 Good choice ;) This is a really good device. I made also very good experience with this one here: Shim ON OFF

@melbmatt50 said in Retropie power switch: As I mentioned before many of the emulators I am not sure if you can program a hot key to escape back to the main retropie menu like you can in mame4all more or less any default emulator in retropie should do this by default. there should be no reason to unplug the pi to turn it off whilst retropie is running.

@cyperghost Awesome thank you! I will definitely go with your solution!

Finally got the switch yesterday and installed. eBay listing said it was a latching switch but it ended up being a momentary. I wasn't able to put the switch on the side like I wanted since it was too long and wide and would interfere with the GPIO pins. This was really the only place I could put it. I have the led ring setup to be on when the pi is on and off when power is off. For anyone installing an led on their Pi 3+, I found that pin 8 (GPIO 14) used for power is set to low(power off) by default on newer versions of the OS, I'm on Linux 9 stretch from the image I got with 4.4.1. To enable it you need to add the following line to /boot/config.txt enable_uart=1 0_1529017022324_IMG_20180614_184123.jpg

@cyperghost Just made use of your mult_switch.sh script. I'm using it for a momentary switch on a 3B running retropie 4.4.1 Worked great thanks.

Instead of using the "enable_uart=1" line in config.txt, I found out it might be more optimal to activate the voltage on pin 8 from inside the retropie>raspi-config>interfacing options>Serial.

@cgeyik I think learning to solder would be the easiest option. As the case comes, the power/reset are hard wired into the power in and all current flows through both buttons. I just cut the traces to the switches, which isolated them from the power circuit and allows them to be used for other purposes, and soldered power in directly to the pins that go to the pi. So eventually you’ll have to solder something to the power in. I did a whole rundown of my build in a couple threads.

How do I use the internal command prompts? Like how do I log in so I can enter in all the code? I know that if you press f4 that it brings up the prompts, but how do I log in and shit?

Ok so I didn't give up so to speak but I did take a different route, I now have a ATXraspi sorting out my power button which leaves my i2c pins freed up. I have connected my 16x2 display as per the guide I've been following but when I check the i2c address there is no assigned address can anyone help me? Thanks. (there is power to the display but no text)

@N-Game-Arts said in Retropie won't boot up anymore after installing Shutdown script: I've done all the updates a few days back (how to tell what update version, I haven't clue When you run retropie_setup, take a look at the top of that dialog box, as in the example below:

Ah, should have read the rules properly sorry

Check out mausberry circuits. Very happy with mine

@edmaul69 Hi i am attempting somthing similar with a Super Nintendo reset button and am looking for a script that will exit the current game and go back the the game select screen. Do you happen to know of a working one? many thanks

You need to reverse that. Most fans are going to need 5v to run. You can also use the 3.3v pin (pin escapes me right now), to run fans quieter, but those are the pins to run fans on for the pi. Also recommended are heatsinks for all of the sensitive chips (including the one on the bottom of the board). Use pins 2 and 9 for the power switch but not recommended for corrupting the sd card. I got one of the push button switches that connect to the micro usb port in between the pi and the power supply. It will also clean up your power feed.

Yes, you need two ControlBlocks to support 4 players. The capability for stackable ControlBlocks was recently added.
