# GPS Clock (STM8S)

Firmware for an STM8SF003 microcontroller to show HH:MM:SS time on six VQB-71 segment  displays, with accurate time from a GPS module. More project write-up, schematics, etc is available on Hackaday: [VQB 71 GPS Clock](https://hackaday.io/project/170633-vqb-71-gps-clock).

The base of this project was ported to STM8S from my [1KB AVR GPS Clock](https://github.com/stecman/avr-doomclock) project.

## Setup

Grab the code:

```sh

git clone https://github.com/stecman/stm8s-vqb71-clock.git

cd stm8s-vqb71-clock

# Pull in SDCC compatible STM8S peripheral library

git submodule init

git submodule update

```

Once the toolchain below is available:

```sh

# Build

scons

# Flash through STLinkV2

scons flash

```

## Linux Toolchain

### SCons (build tool)

This should be available in your distribution's pacakage manager. It can also be installed via Python's `pip` package manager.

### SDCC (compiler)

This project requires [SDCC](http://sdcc.sourceforge.net/) 3.9 or newer.

### stm8flash (flashing tool)

[stm8flash](https://github.com/vdudouyt/stm8flash) uses an STLink V1/V2 to program STM8 devices through their SWIM interface.

This needs to be compiled from source currently, which is simple:

```sh

git clone https://github.com/vdudouyt/stm8flash

cd stm8flash

make

sudo make install

```
