Reset Button with ControlBlock?

detola

Hi there, i am the new guitar in town ;)

so right now i am working on another of these NES Mods.... what I want to be working from the Original:
The Power button - I understand that PowerBlock an Control Block can both help me with that.
The Controller Ports - I need ControlBlock for that.
The Reset Button - I know Powerblock can do it... but can ControlBlock?

so i realy don't want to use both of them just for the Reset button... if ControlBlock can't manage this function, is there another way around this?

thanks a lot... as for a lot of people its my first serious Raspberry Project.... so please talk slow ;)

What do you want the reset button to do? Reboot the Pi? I ended up choosing a Mausberry Circuit for my build to do power and LED. I don't think I'll use it for resetting, but it can do that too.

detola

to be 100% honest..... i am not totaly sure yet.

scenario 1.: just what you describe: Press Reset and the Pi gets rebooted....
or
scenario 2.: Press Reset and the running game gets closed and you come back to the Emulationstation

I am playing with the pi for some weeks.... while playing games i never had a hickup that would require an hard reset like in Scenario 1.... so right now i tend more to scenario 2.

@detola For both of those scenarios you can tie the reset to a GPIO pin and then have that pin execute a script when pressed, and you could do that with the Control Block, since I'm pretty sure that's really just acting as a way to tie in to the GPIO.

I am currently implementing that feature and it seems as if I can add that during the next weekend. If you are interested you can have a look at the current draft at https://github.com/petrockblog/ControlBlockService2/blob/feature/snesreset/src/controlblock/SNESGamepad.cpp. With that feature implemented you can then connect the original reset button to the ControlBlock. The ControlBlock, in turn, will issue an ESC key press, if the reset button is pressed.

Hello guys,
glad to hear thats now implemented into controlblock. I have a question how to wire the reset button to the controlblock? I mean wich port I have to use.

petrockblog

The documentation needs to be extended with this functionality, I agree.

The reset button should be attached to GPIO "Player 2 - B".

Batman6

Allright thank you :)

@petrockblog said in Reset Button with ControlBlock?:

The reset button should be attached to GPIO "Player 2 - B".

Sorry, if this is a stupid question, but what about the second wire? Where should this be attached to? GPIO "GND" on the control block?

@ahaertig
I have attach it to the control block with player one ground. But not testet yet. Waiting for a little part to finish the build. Ill report you if iam done.

Ok it doesnt work dont know why but i will investigate this tomorrow. played to much today with the old games :D

petrockblog

Connecting it to GND on the ControlBlock is the way to go.

If you cannot solve that issue, you could post some pictures here so that we might get an idea about your hardware setup.

@petrockblog
Checked the connection with the multimeter its correct wired so far.
But still not working dont now why. Some pictures for you

Did you ever found out what the problem was? I have a momentary switch connected to GPIO "Player 2 - B" and Ground on the Controlblock but it does nothing. I have checked for continuity and the switch is functioning like it should but software wise it does nothing?

Seeing as this wasn't answered in months i'll debug it myself tonight and rewrite some things if i have to.

For the SNES gamepad type the ESC keyboard key is simulated, see also https://github.com/petrockblog/ControlBlockService2/blob/master/src/controlblock/gamepads/SNESGamepad.cpp#L108. Maybe that points you into the right direction.

@petrockblog The "Reset" function on the ControlBlock does not work as advertised. Please look into this. I believe the firmware in the ControlBlock does not properly bind with Retropie. Has someone got this function working?

petrockblog

I will create a video that demonstrated that feature. I hope that it will also clarify some questions regarding the hardware setup and configuration. I will post that video here as soon as it is published in the next days here!

@petrockblog That will greatly help a lot of us who would want to see this working. Thanks.
