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...

Re: Change 3.5" HDMI display boot logo
I have just released a new version of both the Arduino code and the GUI tool. Both need to be updated. I have added checksums to the telegrams to make the communication more reliable. The connection problems should be solved as well. Sometimes the first few bytes from the Arduino don't reach the PC....

Re: Change 3.5" HDMI display boot logo
Marty33, good to see it working. I will update the software to use 9600 baud. 115200 seems to cause problems for some users. About the unknown firmware: The GUI tool "knows" only a few firmware variants. This is a precaution not to modify every firmware and corrupting it. You can send me the file fi...

Re: Change 3.5" HDMI display boot logo
Someone else had similar problems and for him it helped to press the reset button on the Arduino before clicking "Connect". If you have not given up yet, you can try the following steps: - Connect the Arduino to your PC (don't connect the display to the Arduino) - Start the GUI tool, configure the c...

Re: Change 3.5" HDMI display boot logo
On GitHub two people had similar issues and they solved it by reducing the baud rate to 9600. To do so, change the line in the Arduino code to In the GUI tool, the baud rate is set next to the COM port. I hope this helps...

Re: Change 3.5" HDMI display boot logo
Ok, I assume the sketch has been downloaded to the Arduino properly. Have you tried the GUI with the Arduino connected, but without the display connected? This way we can verify the connection between Arduino and the PC without interference from the display. When you click "Connect", you should get ...
