Detailed Description

A pack, a motor and a propeller, modelled, so every screen runs without a measurement front end.

It runs on the panel, and only while no IOmcu answers: an IOmcu that is answering reports what it measures and leaves the rest empty, so a modelled number and a measured one never appear on the same screen.

Every value it produces carries LINK_BN_SIMULATED, and the router draws SIMULATION across the screen while that bit is set: a modelled number must not read as a measured one.

The model is crude: the bus sags under load, current grows faster than throttle (exponent 2.5), and rpm (revolutions per minute) follows the sagging bus rather than the stick.

Function Documentation

◆ telemetry_sim_init()

void telemetry_sim_init	(	telemetry_sim_t *	s,
		const telemetry_sim_cfg_t *	cfg )

Sets up the model from its configuration.

Parameters

s	The model to set up.
cfg	The configuration, or NULL for the default.

◆ telemetry_sim_step()

void telemetry_sim_step	(	telemetry_sim_t *	s,
		float	throttle_pct,
		float	dt_s,
		bench_state_t *	out )

Advance by dt_s at throttle_pct and fill out.

Peaks are accumulated into out as the IOmcu accumulates them for the BENCH page, so the screen sees the same behaviour from both sources.
