# Aquacomputer protocols
Aquacomputer devices share the same HID report philosophy:
* A sensor report with ID `0x01` is sent every second to the host, detailing current sensor readings
* A HID feature report with ID `0x03` contains the device settings which can be requested, modified and written back to the device
* A control/configuration report that can be requested and sent back to the device, controlling its settings and mode of operation. Contains a CRC-16/USB checksum in the last two bytes
* A save report, which is always constant and is sent after a configuration report (the devices seem to work fine without it, but the official software always sends it)
These devices also share some substructures in their reports. All listed values are two bytes long and in big endian, unless noted otherwise.
### Sensor report details & substructures
There's one important substructure that keeps recurring in sensor reports, and it concerns fan info. The definition of fan here also includes pumps, not only 3/4 pin fans in the literal sense. Here's what it's known to contain:
| What | Where (relative offset) |
| ------------------ | ----------------------- |
| Fan speed (0-100%) | 0x00 |
| Fan voltage | 0x02 |
| Fan current | 0x04 |
| Fan power | 0x06 |
| Fan speed (RPM) | 0x08 |
Temperature sensors, if not connected, will report `0x7FFF` as their value.
### Control report details & substructures
The control report can be requested from and sent to the device using `GET_FEATURE_REPORT` and `SET_FEATURE_REPORT`, respectively. What it contains depends on the device, but it always carries a two byte CRC-16/USB checksum in
the last two places. The checksum is calculated from the data between the starting `0x03` report ID at the very beginning and the (existing) checksum at the end.
Fan speed control subgroups can be found in the control report, and it's currently known that they look like this:
| What | Where (relative offset) |
|------------------|-------------------------|
| Speed curve type | 0x00 |
| Speed (0-100%) | 0x01 |
The `Speed curve type` above understands these values (list may be incomplete):
| Value | Meaning |
|-------|-----------------------------------------------|
| 0 | Manual mode (directly honor percentage value) |
| 1 | PID control mode |
| 2 | Fan curve mode |
The liquidctl driver currently supports only the manual mode.
## D5 Next pump
The D5 Next pump can, aside from itself, control and monitor an optionally connected fan.
### Sensor report
An example sensor report of the D5 Next looks like this:
```

## Quadro
The Quadro exposes four physical and sixteen virtual temperature sensors, and four groups of fan sensor data
(outlined in the preamble) through its sensor report.
### Sensor report
An example sensor report of the Quadro looks like this:
