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.

Re: New RetroStone SBC gaming handheld

I was under the impression this chip didn't support DPI/RBG but one of the pictures clearly states "AV->RGB24". I guess I've been mistaken? The Kickstarter campaign of the original RetroStone has the same picture with "AV->RGB24". I think the only difference is the aluminium case and the lack of th...

Re: Change 3.5" HDMI display boot logo

I have updated the project to v2.0 and added a Python script. This script allows you to read and write the firmware from a Raspberry Pi through a regular HDMI cable. No modified cable needed. You just need to enable the second I2C interface on the Pi, the GitHub page explains how this is done. With ...

Re: KeDei HDMI screen feels sluggish

From my experience, you can't rely on the KeDei displays any more. They have changed the panel a few times but kept the same date on the PCB. The latest KeDei display I got had a screen which wouldn't fit in the shell because it is about 1 mm too wide. And another downside: the response time is very...
