neobirth 0.1.1

Pure Data-powered acid house music synthesizer for the Adafruit NeoTrellis M4 Express
neobirth-0.1.1 is not a library.


Crate Docs Build Status Apache 2.0 licensed Gitter Chat

Acid house music program for the Adafruit NeoTrellis M4, powered by the PureZen music synthesis engine (a Pure Data engine targeting embedded Rust devices).

Inspired by Propellerhead ReBirth.


The current code produces a working executable which can be loaded onto a NeoTrellis M4 device, however no functionality is yet in place (unless you like blinking LEDs).



$ CARGO_INCREMENTAL=0 cargo build --release
$ cd target/thumbv7em-none-eabihf/release/
$ arm-none-eabi-objcopy -O binary neobirth neobirth.bin

Flashing the NeoTrellis M4

Press the RESET button on the back of the NeoTrellis M4 twice in rapid succession. The LED on the back will turn green.

Then run:

$ bossac -e -w -v -b -R -o 0x4000 --port=/dev/<your platform dev> neobirth.bin

Note that the --port flag for bossac varies by OS:

  • Linux: /dev/ttyACM0
  • macOS: /dev/tty.usbmodemNNNNNN (try ls /dev/tty.usbmodem*)
