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

Code: Select all

Serial.begin(115200);
in the Arduino code to

Code: Select all

Serial.begin(9600);
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 ...

Re: Change 3.5" HDMI display boot logo

Sorry, I missed the screenshot with the "Tools" menu. Ok, so the Arduino is configured correctly.

Can you please post the full output log? It would be interesting to know which "invalid" libraries were found.

What is the output from the GUI tool when you connect and don't have the display connected?

Can you please post the full log from the bottom of the window?

Under "Tools" -> "Board", did you select "Arduino/Genuino Uno"?

Re: Change 3.5" HDMI display boot logo

I seems that your Arduino does not even respond to the "read error" command. This should have shown you the exact error reason. Please disconnect the HDMI cable and try again, just to make sure the connection between Arduino and PC works. Before you click "Connect", press the Arduino's reset button ...

Re: Change 3.5" HDMI display boot logo

I would need the firmware of that board to see where the logo is located and if it can be changed. You can use my tool in expert mode to read the firmware from the flash and send it to me.
