Part Number: SN65DSI83

Hi Team,

1.Cannot get correct display on InnoLux 15” LCD.
2. How can we check SN65DSI83 DE mode enabling or not? Read register 0x18 to check bit 7 DE_NEG_POLARITY or other ways?

Hi,

Register 0x18 only sets the DE polarity, you can probe the DE pin to verify the DE pin is being driven correctly.

Please see this e2e FAQ for DSI83 debugging guideline, https://e2e.ti.com/support/interface-group/interface/f/interface-forum/852871/faq-sn65dsi84-no-display-output-with-sn65dsi83-sn65dsi84-sn65dsi85.

Thanks

David
