Re: Minecraft with Pi Hut Wireless Gamepad / Controller

After many more hours of looking, I have discovered Qjoypad which maps USB joypads to a keyboard or mouse button. This is perfect for everything and allows the controller to move around and do all the actions that I need. The only issue is the 'looking around' which is normally done using the mouse....

Thanks for the quick reply. I had a look at the datasheet and it doesnt quite match your picture as there is an additional connection. Could you just advise where I would connect terminals B, C and E??

Monitoring 12V 100mA output from a burglar alarm

My alarm can be programmed to output a 12V 100mA signal when an 'event' happens. Id like to connect this output to the Raspberry Pi GPIO to sense these events and then do something. Obviously the Pi cannot accept 12V to the GPIO input so I need something inbetween. I like the look of opto-isolators ...

Re: Trouble with GPIO threaded callbacks being ignored!

Quick update, it appears that the only thing causing it is the "os.system("sudo mount /dev/sda1 " + usb_directory) line. The "Check_USB_is_mounted" makes no difference to the GPIO inputs.
