+There won't be any `IrDA` as R&D discovered the following problems:

+- The "classical" low-bandwidth chips for e.g. TV remotes aren't usable for UART communication. At `9600 Baud` there is half text half garbage, at `4800 Baud` we got 2-3 wrong chars per line (~40 chars).
+- **ANY** higher-bandwidth `IrDA` chips are either very expensive (8$ for `LT1328` IF you even get one) and the `16 MBaud` ones are completely ungettable and 2-3x more expensive!

SiliconTorch
============
-`SiliconTorch` is the `python` reference implementation for the `fxCyanF`-protocol
+`SiliconTorch` is:
+
+- `CyanBus` library for `ESP32` (client) and `Python` (server)
+- `fxCyan` animation protocol library for `ESP32` (client) and `Python` (client/server)
+- its own adapter to the [Weaponsmith](https://git.c3pb.de/jonsen/weaponsmith) eco system
It will be moved to a separate repo when it matures

+
+### `CyanBus`
+
+`CyanBus` will be the main working horse of `SiliconTorch`.
+
+It consists of a `RS485` and a `MQTT` layer, the first for real-time animation data and the second one for signalling.
+
+`RS485` packets look like below, `CRC` is calculated over payload only.
