This repository contains the firmware for the Dato DUO synthesizer serial numbers 4630 and up.
Grab one of the binaries from https://github.com/datomusic/duo-imxrt/releases Make sure you have Python 3 installed
in the commandline, go to the tools/updater directory and enter
python3 -m pip install -r requirements.txt
use python3 update_firmware.py
if on Mac you get an error usb.core.NoBackendError: No backend available, please install libusb by running brew install libusb
Make sure you have version 12.3.rel1 of the Arm GNU Toolchain for embedded installed: https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads . It has 'eabi' in the filename.
Git clone this repository including submodules
git clone --recurse-submodules https://github.com/datomusic/duo-imxrt.git
Go into the apps directory
cd duo-imxrt/brains2/apps
Tell the build script where the compiler is and run the build script
export TOOLCHAIN_DIR=/Applications/ArmGNUToolchain/12.3.rel1/arm-none-eabi && ../scripts/build.sh duo
If you get an error saying that The CMAKE_C_COMPILER: /bin/arm-none-eabi-gcc is not a full path to an existing compiler tool. make sure the path at TOOLCHAIN_DIR is valid and points to the arm-none-eabi dir
If you get an error along the lines of Cannot find source file: /duo-imxrt/brains2/libraries/tinyusb/src/class/cdc/cdc_device.c make sure all submodules are downloaded. You can make sure all submodules are fetched by running git submodule update --init --recursive
If the build is successful you can upload it by running ../script/send_firmware.sh duo. You will need all correct python libraries as well so make sure you followed the instruction at "Updating the firmware" to install them.
The main pcb of the Dato DUO is dubbed Brains. Up until mid 2022 the Brains 1 were based on the NXP K20DX256 microcontroller. Due to ongoing problems with availability of that chip family later Brains 2 are based on NXP iMX RT1010
Source code for the two different platforms can be found in the platforms directory.
