In LPC55S69's SDK，is there any examples about RS485 how to use .or can you give me a link of the code of RS485. Pleasse.
Unfortunately, we have only uart example in SDK package for LPC55S6x, but we have not RS485 example code. For RS485, you have to use a GPIO to control transmitter to enable/disable based on uart module.
Pls download SDK from the link:
