Ultrasonic range finding on a myRio using the HC-SR04

[tomnz]

This program uses the FPGA and real-time controller to measure distance in cm using the HC-SR04 ultrasound module.

Unrar the attached files. Make the following connections from the ultrasound module to the myRio

Vcc to Pin 1 (+5v)

Gnd to Pin 12 (zero volts)

Trig to Pin 11

Echo to Pin 13

(all port A connector).

Compile the FPGA code. Then run the program Main on the real-time controller. A video of this is shown at the link below.

I would like to get this going but am new. However, the folder above will not extract as it states it is empty (size shows as 755 kB). Any help would be appreciated.

Ok so it wasn't empty, the web page deleted it because it doesn't like .rar files. I don't have a zipper I am afraid. Email me and I can post it. Don't know why they don't like .rar.

Have updated the file as requested. Sorry a bit was missing.

Hello tomnz!

In your video you have mentioned that NI provided you with the code. Can you be more specific and help me trace down this source?
