MiniZed Midi Notes
Create a wind chime that transmits the XY position of its sail as a value to a receiving station. The receiving station (MiniZed development board) converts the XY position to a midi value which in turn can be sent a raspberry pi which plays music and controls lights.

Minized Development Board:
The MiniZed
is a single-core Zynq 7Z007S development board. This compact design features on-board connectivity through USB, Wi-Fi and Bluetooth. Peripherals can be plugged into dual Pmod-compatible connectors, the Arduino-compatible shield interface or the USB 2.0 host interface. JTAG circuitry is incorporated onto the MiniZed base board, so with a single micro- USB cable to your laptop you are already up and running. User LED’s, a button and a switch allow for a physical board interface.
Specifications for the Board:
- Xilinx Zynq XC7Z007S SoC
- Micron 512 MB DDR3L,128 Mb QSPI flash, 8GB eMMC
- Murata Wi-Fi 802.11b/g/n
- User button, switch, 2 x OSRAM bi-element LEDs
- On-board USB to JTAG and debug UART circuit
- Murata Bluetooth 4.1 plus EDR
- USB 2.0 host (Microchip PHY), 2 x Pmod, Arduino interface
- Dialog Semiconductor PMIC
- ST Micro Accelerometer & Temperature sensor
- ST Micro Digital MEMS microphone
Project Status
After studying the features of the MiniZed in more detail and considering all the possibilities this board offered, I decided to change how I had initially thought I would build the device.
Using the motion sensor feature I could eliminate the multi-directional rocker switch for the sail.
Search the internet for general information on wind chimes, I believe I have narrowed the noted to eight (8: N, NE, E, SE, S, SW, W, NW)
1. F 4 113
2. G 4 115
3. A 4 117
4. B 4 119
5. C 5 120
6. D 5 122
7. E 5 124
8. F 5 126
Sound/Audio Players
The Adafruit Audio FX Sound Board, WAV/OGG Trigger with 16MB Flash. It does not provide polyphonic audio output.
The Robertsonics wav trigger board, exceeds the requirements for this project.
It is a polyphonic audio board that can blend up to 14 tracks at a time. Each track can start, pause, resume and stop independently, and can have it’s own volume setting, allowing you to create the perfect interactive mix of music, dialog and sound effects. The WAV Trigger supports the MIDI protocol on its serial control port, enabling low-latency, 14-stereo voice poly-phony for creating a basic musical instrument sampler with a real-time playback rate control (sample-rate conversion) and MIDI Pitch Bend. It has a MIDI serial connection for input.
- Supports up to 2048** uncompressed 16-bit stereo WAV files up to 44.1kHz – CD quality
- Polyphonic! Play and mix up to 14 stereo tracks independently and simultaneously
- Sample-accurate starting and playback of up to 14 parallel stereo tracks
- Real-time playback rate control and MIDI Pitch Bend**
- Trigger-to-sound delay: 8 msecs typ, 12 msecs max
- Pause and resume individual or groups of tracks
- Multiple random trigger ranges
- True line-level stereo output: 2.1V RMS ground centered, 100dB SNR
- On-board mono audio amplifier and speaker connector. 2W into 4 Ohms, 1.25W into 8 Ohms, 1% THD+N
- 16 trigger inputs are individually adjustable for contact closure, 3.3V or 5.0V control
- Trigger inputs can be individually inverted (active low or high)
- Trigger inputs can be individually set to be edge, latched** or level sensitive
- Output volume adjustable from +10dB to -70dB in 0.5dB increments
- Firmware track fades (attacks & decays) and cross-fades
- A dedicated “Play” status digital output pin
- 3.3V and 5.0V output pins
- Extensive serial control. Pin compatible with SparkFun FTDI Basic
- MIDI serial option; Velocity-sensitive triggering of up to 2048** tracks
- Low-power sleep mode option
