Detailed Description

Electrical description of an analog port — the jack-to-converter circuit.

Describes what sits between a jack and the ADC: the voltage span the full code range represents, the converter resolution, and whether the front end inverts. Instances are generated by sloth from the hardware manifests into sbl::hw::electrical (config/electrical.hpp); components derive their conditioning from them. Hand-written instances are for tests and one-offs.

Codes are right-aligned unsigned counts, 0 .. (2^bits - 1), as the ADC drivers deliver them (STM32H7: RM0433 Rev 8 §25.6.15, right-aligned by default).
