NI myRio and ultrasonic sensor

[hyperionrobotics]

Hello everyone,

I would like to calculte distance using my ultrasonic sensor MB1040 (http://maxbotix.com/documents/LV-MaxSonar-EZ_Datasheet.pdf) with my NI myRio.

The connections that i have made with the sensor and NI myRIO MXP Connector B are shown below:

 1. VCC: A/+3.3V (pin 33)

 2. GND: A/GND (pin 30)

 3. TX: A/UART.RX (pin 10)

But my code has the error -1073807253

Any help is much appreciated !

Thank you for your time.

Are you really using myRIO??

Also you can post it here to get quick reply for issues related to academic hardware.

If its just a serial communication give some time to read data in the loop(add wait) - Else refer Find example for basic serial read write

First of all thank you for your answer. I tried to give some time to read data in the loop but i still have the same error.
