Re: Using battery to pwer pi and hooking up usb hub

I tested it with my tablet before I started dissambling it and it worked like it should. So... yeah. That doesn't really anwser any of my question though. Even if power wasn't passed on to the top micro usb why would the pi just flat out refuse to power on when the wires of the power are connected?.

Re: GPIO keyboard input - using key combinations

Hm... Weird... the schematic graphic doesn't show that... Bummer. I guess I have to remake the entire PCB from scratch again.

Re: GPIO keyboard input - using key combinations

What cross? I'm staring at the PCB and can't find a single cross. Even looking at the schematic I don't see a single ground connection except for the power input.

Re: GPIO keyboard input - using key combinations

That's just it. Aa far as i can tell all the buttons are only connected to the gpio pins but not ground, so that's why I'm confused.

To be honnest I don't understand what you were trying to tell me with the button combos.

GPIO keyboard input - using key combinations

I'm connecting tact switches to the GPIO pins of the pi (haven't done it yet because I'm not using the pi cable). I'm using the pi girrl controller PCB (though I made it myself) and the retrogame configuration file. The pcb: https://www.adafruit.com/product/3015 the file: https://github.com/adafruit...

I'm trying to install a waveshre 3.2 lcd screen to the pi zero connected via GPIO but I can't get Fb1 to show up. Is there any specific reason for that? I'm using a fresh install. I also tried with pi2 and there it works fine but I already tried 3 or 4 times on the zero with fresh installs of retrop...

Re: pi zero doesn't power on with usb hub soldiered to it.

I desoldered the hub and reconstructed it and it works so it's not a problem with the hub. I haven't tried soldering it on again but I'm guessing it was a mistake on my part.

pi zero doesn't power on with usb hub soldiered to it.

Hello. I just tried soldering an unpowered usb hub to the pi zero. I soldered the hubs power to PP1 the ground to PP6, DP to PP22 and DM to PP23. When I tried to power up the pi it wouldn't boot. I desoldered the wires and tried powering the pi again. It powered up normaly. Is there any specific rea...

Re: trouble setting up TFT screen

I managed to solve the problem. I found out this is a cloned screen of the waveshare 3.2 so I had to follow different steps to make it work. Kind of easier steps actually :P The good people at retropies forums pointed out this tutorial for me: https://retropie.org.uk/forum/topic/295/retropie-and-wav...

I checked out the voltage comparator a bit and to be honest... I kind of understand it but I'm not willing to pay 12 dollars for an IC that I don't know will work for my project. I'm trying to put together a project that's cheap and anyone can build (even myself :P). Would something like this work? ...
