Question about How it works

[koalatje2000]

Hello, I'm working on this project too, and I aim to get it running on the display's second port. I have a couple of questions regarding the transmission of button data:

• Can I simply send 3 bits of button data followed by 3 clock pulses directly to the print, and will that work as intended?
• Or should I transmit both the display and button data over the line, since the 3 bits are follow-up bits within the display message?

Additionally, in your setup—where you're positioned between the controller and the display cable—do you use the full message and swap only the last 3 bits, or do you send a new request during the roughly ±16ms interval when the display isn't communicating?

Thank you in advance. Once I get it working, I'll showcase my system. Hopefully, it can help you improve yours.

Best regards,
Wouter

Hi @koalatje2000

I tried the second port during developmend but I nerver get it to work! Perhaps I didn’t put enough time to sort out why.

The code calculates the message sent between controller and display and simulates button presses on the bit positions explained in description, section button-data. The only thing you need to simulate is the button pushes
