\uD83E\uDD14 Problem Statement

Determine the necessary requirements & future expansion for a HIL Controller for verifying ZP. The HIL should allow for mocking of sensors, peripherals, and “environment” while verifying that outputs from ZP are as expected.

will this ever interface with the simulator?

🎯 Scope

Current Must Haves:

PPM Output to emulate controller signal
Hardware ARM/Disarm signal → ZP (button emulation)
Send/Receive Telemetry Data
Passthrough Telemetry to Ground Station
Interfaces over USB
Analog ↔︎ Digital conversion up to 6s VBatt.
- monitor battery [status]
Mock IMU, GPS
- by extension, mocked interfaces (spi/i2c/uart).
Remote access incl. remote flashing.
Test suites (small regressions for now).
Ability to reset ZP (toggle reset line on ZP) (or remote flashing).

Future Expansion:

Add-on with analog components for user-input to HIL
Mock more sensors (Airspeed, Barometer, OFS, etc).
Future expansion for more complete test suites.
Actuator output checking? (in a safe way)
hardware monitoring (temperature / current / power / etc)

Not in scope:
