Hello, can anyone hear me? After the last post, I checked all the content of this topic one by one, and I found a preset that is very suitable for my current hardware conditions: Robopeak, which also uses a 320x240 screen, and uses full-speed USB as the hardware interface, Because Robopeak's firmware is not open source, I want to use the current new screen and new MCU to make a fully open source USB2LCD. At present, I have completed the hardware part, and I am still working on the software part. I hope to know some details about the communication between Robopeak and AIDA64, so that I can use it as a reference when writing the firmware, and get as close to Robopeak as possible so that you can understand it quickly. Of course, if you are interested, I can send you the hardware, including all documentation and code. I will be very grateful if you reply me.
