Heck Daisy Template

Daisy project template featuring:

• toolchain setup
• dependencies setup
• build scripts
• upload (DFU and JTAG)
• debug
• clang-format
• clang-tidy

git started

to use git, either die or use hecks git-ui.
heck-git-ui: https://gitea.heck.live/heck/HeckBashSetup/src/branch/master/bash_profile.d/git.sh

Alternatively, you can avoid using git... TODO

Toolchain Setup

Compiler

compiler used is gcc for arm:
Options:

• install version specified by electro-smith: https://developer.arm.com/downloads/-/gnu-rm
• install the latest version: https://developer.arm.com/Tools%20and%20Software/GNU%20Toolchain

IMPORTANT: Do NOT use any OTHER gcc-arm toolchain than these ones!!! There is a pitfall that is quite hard to debug. I used the gcc-arm from macports. There is NO libc-nano shipped with it, because its not GPL. BUT the daisy build scripts specify the use of libc-nano.

Programmer / Debugger

on macos: port install dfu-util openocd

dfu-util is the program that is invoked by the Makefiles to program the thing via DFU. openocd is the program that is invoked by the Makefiles to program the thing via JTAG. openocd also is the debugger we use.

Flashing

Can be flashed via:

• DFU: all you need is a micro-usb-cable
• JTAG: any JTAG programmer will work, but the STLink v3 is the fastest.

DFU

No magic, you just need a program called dfu-util.
TODO...

JTAG

no magic, you just need a programm called openocd

TODO: The JTAG method is heavily recommended since JTAG is faster than DFU, and if you use the (product ad ahead warning, sorry)
STLink v3 its even faster. Its the fastest method i know of.

Benchmark DFU vs. JTAG

DFU: 15.725s
JTAG: 1.850s

JTAG is at least 8.5 times faster (since there is constant time overhead)

[heck@YOOROOX::~/src/DaisyExamples/seed/Blink] (master ?M) $ time m program-dfu;
dfu-util -a 0 -s 0x08000000:leave -D build/Blink.bin -d ,0483:df11
blabla...
...
real	0m15.725s

[heck@YOOROOX::~/src/DaisyExamples/seed/Blink] (master ?M) $ time m program;
openocd -s /opt/local/bin/openocd/ -f interface/stlink.cfg -f target/stm32h7x.cfg -c "program ./build/Blink.elf verify reset exit"
blabla...

Debugging

TODO:

Daisy Coding

• C++ bare metal like any STM32 - needlessly brutal
• C++ and libDaisy - libDaisy is the electro-smith hardware abstraction
• Pure-Data patch compiler
• JUCE
• FAUST for DSP algo
• Max-msp gen~ (proprietary $hit)

C++ Bare Metal

Just code like for any STM32 - needlessly brutal
TODO: add hecks STM32 project

C++ and libDaisy

libDaisy is the electro-smith hardware abstraction and is basically what makes the daisy be the daisy. TODO:

Pure-Data Patch Compiler

this here: https://github.com/electro-smith/pd2dsy
TODO: Marc? anyone?

JUCE

TODO: anyone?
e.g. https://github.com/electro-smith/Daisy-Juce-Example

FAUST

This here: https://faust.grame.fr/ stahl has workflow/project

Max-Msp gen~

max is the proprietary version of pure-data, but dont want to exclude them just for that. gen~ alone will cost you extra $$$ after even you paid for max. just so you know, hu?

Daisy-Hardware

TODO: PLEASE everyone share their hardware HERE!
