My name is James Willis. Each MIDI message includes channel number, the note to be played, note start time and note duration.

Now that the embedded software both real time and FPGA is developed and the hardware wired, there is one final piece of the puzzle If your interested in doing a placement at NI, have a look at this page. The next task is to change the motor direction when the floppy drive’s read head reaches the end or the start of the disk.

For example, the note C4 would be a frequency of This was a very simple process that required no programming what so ever. See the formula below. The myRIO effectively plays the disk drives like musical instruments, by stepping the disk drive’s integrated motors at specific frequencies.

Open a power supply without destroying a transformer How To: Finally, after the myRIO has finished playing a song, the read head must be return labvlew to the starting position, by driving the motor back the remaining steps.

I’m a student from Cardiff University studying electrical and electronic engineering, currently on my placement year working as a Applications Engineer at National Instruments.

These messages fooppy then be turned into arrays of notes for each channel on the myRIOs realtime processor, which can then be passed down to the FPGA. A MIDI file has up to 15 tracks of messages, each representing a separate instrument within the song e.

Therefore, two loop cycles is equal to one wave period. Hack a coin operated laundry machine All Hot Posts.

Have any old school floppy drives lying around? Share Your Thoughts Click to share your thoughts. Mod a flashlight into an IR night vision light How To: This project uses a myRIO embedded controller and four floppy disk drives.

Make a satellite dish Wi-Fi antenna for free internet How To: Using this information, I created a custom counters on the myRIO FPGA to ensure that the direction of the motor changed lagview it reached the start or end of the disk. Make a Spot Welder for Cheap! This can be done quite simply using the custom counter that is already created.

This frequency value is then passed lxbview the myRIOs on-board FPGA, which generates a digital pulse train used to control the floppy drive motors. Rather, it is a spreadsheet-like set of instructions”.

Hack your electricity meter How To: Therefore the floppy drive’s integrated motors are designed to step the read head through each of these 80 tracks. Please enable JavaScript to watch this video. More specifically, the disk is divided labvisw 80 data tracks arranged in concentric circles, like the rings on a tree.

So, for values the read head will go forward writing folppy digital true on the direction line of the floppy drivethen for the read head will go back a digital false to the direction line.

Batman Arrow How To: A bit of ancient history This setup is then duplicated for how many drives you have to wire to the myRIO. The wiring requirements of myFloppyDriveQuartet are quite simple, because each drive needs just two digital lines—one for step and one for direction.
