@ -2,6 +2,7 @@ The LED clock is an add-on for round wall clocks.
The purpose is to have LEDs on the circumference of the clock to show the progress of the time using coloured light.
For that you will need:
- a WS2812b RGB LEDs strip (long enough to go around the clock)
- a development board with a STM32F103 micro-controller and 32.768 kHz oscillator for the Real Time Clock (such as the blue pill)
- a coin cell battery to keep the RTC running (optional)

The current implementation uses a [blue pill](https://wiki.cuvoodoo.info/doku.php?id=stm32f1xx#blue_pill).
The underlying template also supports following board:
- [Maple Mini](http://leaflabs.com/docs/hardware/maple-mini.html), based on a STM32F103CBT6
- [System Board](https://wiki.cuvoodoo.info/doku.php?id=stm32f1xx#system_board), based on a STM32F103C8T6
- [blue pill](ihttps://wiki.cuvoodoo.info/doku.php?id=stm32f1xx#blue_pill), based on a STM32F103C8T6
**Which board is used is defined in the Makefile**.
This is required:
- for the linker script to know the memory layout (flash and RAM)
- map the user LED and button provided on the board
