More project write-up, schematics, etc is available on Hackaday: [VQB 71 GPS Clock](https://hackaday.io/project/170633-vqb-71-gps-clock).\n\nThe base of this project was ported to STM8S from my [1KB AVR GPS Clock](https://github.com/stecman/avr-doomclock) project.\n\n## Setup\n\nGrab the code:\n\n```sh\ngit clone https://github.com/stecman/stm8s-vqb71-clock.git\ncd stm8s-vqb71-clock\n\n# Pull in SDCC compatible STM8S peripheral library\ngit submodule init\ngit submodule update\n```\n\nOnce the toolchain below is available:\n\n```sh\n# Build\nscons\n\n# Flash through STLinkV2\nscons flash\n```\n\n## Linux Toolchain\n\n### SCons (build tool)\n\nThis should be available in your distribution's pacakage manager. It can also be installed via Python's `pip` package manager.\n\n### SDCC (compiler)\n\nThis project requires [SDCC](http://sdcc.sourceforge.net/) 3.9 or newer.\n\n### stm8flash (flashing tool)\n\n[stm8flash](https://github.com/vdudouyt/stm8flash) uses an STLink V1/V2 to program STM8 devices through their SWIM interface.\n\nThis needs to be compiled from source currently, which is simple:\n\n```sh\ngit clone https://github.com/vdudouyt/stm8flash\ncd stm8flash\nmake\nsudo make install\n```","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstecman%2Fstm8s-vqb71-clock","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fstecman%2Fstm8s-vqb71-clock","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstecman%2Fstm8s-vqb71-clock/lists"}
