AM625: Interfacing LCD to AM625x

Premalatha Royappan

Part Number: AM625

This is with regards to interfacing LCD to AM62xx processor. We are using the OLDI interface to connect LCD.
The LCD datasheet has segregated even and odd pairs on the data and clock lines. We would like to know if there are any recommendations for
interfacing this type of LCD to the processor, as the AM62xx OLDI interface doesn't have such odd and even segregation.
I have attached the LCD datasheet for your referancLCD185-101CTL1ARNTT.pdfe.

Hi, the AM62x processor does actually have "Odd/Even" requirements when using OLDI in 2 channel mode. A0 through A4 correspond to the ODD pixels and A5 through A7 correspond to the even pairs.

The EVM schematic might provide some context.

Best Regards,

Andrei

Hello Premalatha Royappan

Please note change below.

The AM62x processor does actually have "Odd/Even" requirements when using OLDI in dual link mode.

A0 through A3 corresponds to the ODD pixels and A4 through A7 corresponds to the even pairs.
