Re: Looking for advice on my 1st Gameboy 3b+ build.

May I suggest our daddelkischde 2 AIO board? It has all the features included in one single board and supports the Pi 3 A+ (no need to strip down a 3 B+). Check my signature for more details.

Re: INA260 Question

The INA260 seems to be a very nice and powerful board. But I think it is a little too much for your needs. Do you really want to meaure the current? To get the battery percentage, it is enough to measure the battery's voltage. This can be done with any of the Bluefuit's analog inputs. Just connect t...

Re: Testing a new 3.5” 640x480 IPS DPI LCD

The initialization data is usually not stored in the LCD controller. You have to initialize it on every power up.
The parameters are not trivial, especially if you have to write a gamma table. You will need to ask the manufacturer for the correct initialization data or sniff it [;)]

Re: Change 3.5" HDMI display boot logo

Can you please send me the firmware and a picture of the cable with the display model name to floppes@gmx.de? I will check it and add it on Sunday when I'm back home.

Re: Change 3.5" HDMI display boot logo

There seems to be a different EEPROM on your board. It should be compatible with the known ones. If you are familiar with coding, you can add your JEDEC ID in the code and it should work. Or just replace 0x1C3113 in line 47 of rtd266x.cpp with your ID. Are you sure it says LGH-3905? I've seen LGH-35...

Re: HDMI Display Problems with Pi 3A+ and LS060R1SX01 screen

I had a similar problem with a 320x480 DPI display. It's native orientation was portrait mode, but I wanted it to be in landscape mode. Just rotating it resulted very similar to your second picture: big black borders and the aspect ratio didn't change. By forcing the framebuffer size ( not the maxim...

Re: Pwm audio with retropie 4.4 and fresh install

Did you set the audio output in the RetroPie Audio setup to "Headphones - 3.5 mm jack"?

Re: Connecting shoulder buttons to ground - where?

Yes, the Pi has several GND pins. They are all connected internally. You can use any of them.

Just make sure your solder connection is good and the wire is thick enough for the current it has to conduct.

Re: Connecting shoulder buttons to ground - where?

Generally speaking, you should have all GNDs connected. The GND of the Raspberry Pi should be connected with the GND of your PCB and the GNDs of your shoulder buttons. That's called a "common ground". How you do this is up to you.
