The layout is an isomorphic layout similar to the\n[Striso](https://www.striso.org/), which is similar to the\n[Wicki-Hayden\nlayout](https://en.wikipedia.org/wiki/Wicki%E2%80%93Hayden_note_layout).\n\n![photo](images/midi-grid.jpg)\n\n## Compiling and flashing\n\nFor easy dfu flashing without a ST-Link v2, we use the [STM32duino\nbootloader](https://github.com/rogerclarkmelbourne/STM32duino-bootloader/).\n\nFirst, install all the needed software:\n\n```shell\ncurl https://sh.rustup.rs -sSf | sh\nrustup target add thumbv7m-none-eabi\nsudo apt-get install dfu-util\n```\n\nCompile the firmware:\n\n```shell\ncd midi-grid\ncargo objcopy --release -- -O binary midi-grid.bin\n```\n\nThen, install the bootloader on the blue pill. After connecting the\nblue pill with the ST-Link to the computer, type:\n\n```shell\ncd midi-grid\nopenocd -f interface/stlink-v2.cfg -f target/stm32f1x.cfg -c \"init; reset halt; stm32f1x mass_erase 0; program generic_boot20_pc13.bin exit 0x08000000\"\n```\n\nRemove the ST-Link v2 and plug the blue pill with a USB cable to your\ncomputer. It should now be in DFU mode. Now, flash the firmware:\n\n```shell\ncd midi-grid\nsudo dfu-util -w -d 1eaf:0003 -a 2 -D midi-grid.bin\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftexitoi%2Fmidi-grid","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ftexitoi%2Fmidi-grid","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ftexitoi%2Fmidi-grid/lists"}
