RS485 Problem

[nsk1]

Dear all,

Greetings.

We are having some problems in development of the drivers for controller LPC54618.

Can you please help me in using RS485 communication with transmit and receive interrupts using the transmit enable pin of RS485 transceiver.

Hello Sudheer nulu,

Instead of developing your own drivers I recommend you to download the MCUXpresso SDV v2.4.1 for the LPC54618. Within the SDK you will find the drivers for all the peripherals of the LPC along with example projects. Link to download the MCUXpresso SDK: Welcome | MCUXpresso SDK Builder 

The LPC54618 USART has two pins for flow control: Request to send and Clear to Send, are these the signals you are referring?

Regards,

Victor.
