Usage
To clone this project
This project work with submodule from Nuvoton corporation. You need to initialize submodules by passing --recurse-submodules to the git clone command.
git clone https://github.com/danchouzhou/Nuvoton-VScode-template.git --recurse-submodulesBuild tools
Windows users
Since we use VScode setting.json provide the build environment, only the execution binary need to be download (without installing). Download the following files, extract to the path C:\Users\"Your user name"\BuildTools\Windows which specific in .vscode/setting.json.
- gcc-arm-none-eabi-10.3-2021.07-win32.zip
- xpack-windows-build-tools-4.3.0-1-win32-x64.zip

Linux users
mkdir -p ~/BuildTools/Linux/
tar jxvf gcc-arm-none-eabi-10.3-2021.07-x86_64-linux.tar.bz2 -C ~/BuildTools/Linux/
unzip OpenOCD_Linux.zip -d ~/BuildTools/Linux/
chmod +x ~/BuildTools/Linux/OpenOCD/bin/openocd- GNU Make should be installed.
sudo apt install makeBuild the template
If you want to build the target for Nuvoton M480 series for example. Open a terminal inside the VScode.
cd firmware/LLSI_RGBWSimply make. LLSI_RGBW.bin should be inside the Objects folder.
makeFlash the firmware
make flashFor Linux users, probably need to add the access permission for usb device.
sudo chmod -R 777 /dev/bus/usb/Rebuild
make clean
makeCreate your own project from this template
- Add BSP submodule from OpenNuvoton. For example:
git submodule add https://github.com/OpenNuvoton/M480BSP.git NuMicro-M4/M480BSP- Edit

Questions
How big is the LLSIClock PCB?
It measures 80 × 21 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LLSIClock use?
31 parts, built around the MCP1702T-3302E/MB(UMW), TSM-107-01-L-DH and USB4085-GF-A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LLSIClock KiCad files?
From the danchouzhou/LLSIClock repository on GitHub, at the commit this page was made from: the board is kicad/LLSIClock.kicad_pcb and its schematic kicad/ELSS-4X6RGBWA-T2-S290-C.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LLSIClock design in my own project?
Its repository states no licence, so its author keeps all rights: ask danchouzhou before reusing the design.
