Sensors API #37
Description
We should report sensor info, up to 255 of them. Just like the other APIs.
Neotron Pico BIOS can provide:
- CPU temp (RP2040 on-die reading)
- 5.0V and 3.3V rail voltage (from BMC)
- perhaps some info from the RP2040 bus matrix (bus collisions, etc)
- ROM and die revision
Each value should be of an enum representing the units, and which holds a u32 or similar. This type can then impl Display for printing.
Kind::Voltage(u32) might print as xx.yyy V and be stored in units of 1/1000 Volt.
Kind::Temperature(u32) prints xx.y °C but is stored in units of 1/100 Kelvin.
Kind::RawHex(u32) prints 0xXXXXXXXX
Kind::Percent(u8) prints as xxx %
etc
Each sensor also has a human readable name.
