Want to send data from Arduino Mega to NI Myrio 1900

Other Hardware 3rd Party Boards

Hi friends,

I am working on a project where I need to send data collected via sensors from Arduino Mega and send the data to Ni MyRIO 1900.
How can I communicate between Arduino Mega and NI MyRIO 1900?

Thanks in advance.

Hi,

What is a "Ni MyRIO 1900" and can you please post a link to data/specs?
What sort of communication types does it support?

Thanks... Tom.... :smiley: :+1: :coffee: :australia:

the Ni MyRIO 1900 appears to have UART TX on pin 14 and Rx on pin 10 of connectors A/B
you could use one of the Megas hardware serial ports to communicate
the device uses 3.3V logic and may be 5V tolerant - however, I would recommend using a potectial divider on the Mega TX to NI RX
why not connect your sensors directly to the NI micro? no need for the Mega?

NI MyRIO is a micro controller which works like an Arduino. We have to use LabVIEW software.
I am collecting data from MPU 6050 and FSR by using Arduino Mega and I have to send this data to NI MyRIO for the actuation based on the sensor data.
I am attaching the images of pin out of NI myRIO

Thank you for the answer.

I will try the UART connections and also try to collect data directly.

Hi,

Is this a school/college/university project?

Have you tried to use the resources of your educational institution?

What is your electronics, programming, arduino, hardware experience?

Thanks.. Tom.. :smiley: :+1: :coffee: :australia:

It is a college project.
I have done some basic projects with Arduino and trying to do the same with MyRIO.

the first diagram in post #4 shows the MyRIO has UART TX on pin 14 and Rx on pin 10 of connectors A/B
does Labview have methods to connect to the MyRIO UART and read/write information from/to the Mega?
if so you should be able to connect mega Serial1 pins 18 Tx to MyRIO pin 10 Rx and Mega pin 19 Rx to MyRIO pin 14 - I would recommend using a potectial divider on the Mega TX to NI RX
