## Building

## Getting the firmware
|
||||||
|
|
||||||
Pick your poison - firmware version: older with Pounder support or newer with USB serial console - the first works with a hardcoded MQTT broker and (static or dynamic) IP address, the latter is configured like the booster - through a serial console.
|
You can get the firmware from [Hydra](https://nixbld.m-labs.hk/jobset/mcu/mcu-contrib).
|
||||||
|
|
||||||
|
* ``stabilizer-dual-iir`` supports Pounder v1.2 - probably you should flash this one,
|
||||||
|
* ``stabilizer-dual-iir-pounder_v1_0`` supports Pounder 1.0 and 1.1 (legacy),
|
||||||
|
* ``stabilizer-lockin`` is a different application which we do not usually flash.
|
||||||
|
|
||||||
|
These all include changes to the mainline code to include Pounder telemetry.
|
||||||
|
|
||||||
|
### Building (optional)
|
||||||
|
|
||||||
|
Please keep in mind that the firmware from the official Quartiq repository does not include support for Pounder in MQTT, you may need to use a fork for that. But if the stabilizer is without a Pounder, it's also a valid option.
|
||||||
|
|
||||||
There is no Nix Flake support to make things easier, so you need to set up rust and cargo manually. Start with cloning the stabilizer repository and opening a new shell with dfu-util (for flashing) and rustup (for building).

For normal usage, the stabilizer must be configured with USB console later (try ``help`` command first), to set its IP address and MQTT broker address. However, for general testing (like the one below), you don't need to configure it any further.
