Serial port available and max baudrate

Unread post by elgarbe » Tue Sep 11, 2018 7:51 am

I want to connect mi odroid C2 with a pixhawk flight controller. The FC could be configured at 115200, 500000, 921600 and 1.500.000 bps
What of them could be used on odroid running ubuntu mate?

Thank!

There are up to 4 UART ports.
https://wiki.odroid.com/odroid-c2/appli ... /gpio/uart

As far as I remember, the maximum baud rate is 921600.

I will use ttyS1 on pin 8-10
Is there a way to confirm that without error test?
Could I get more speed using a USB to uart converter?

Thank!

What do you mean without error test?
The USB-to-SERIAL converter can support the baud rate as much as it supports regardless of CPU performance but would depend on USB bandwidth.

I mean without try every baudrate and see if it works or not. Is there a way to confirm the max baudrate?

Thank!

The datasheet suggests up to 8,000,000 bps and I think Ubuntu mate would be fine with 1,500,000.
