Detailed Description

JVS to Dreamcast controller translation

During polling the driver fills mie_state_t::cont from native JVS inputs using the active mapper. Pass NULL to mie_set_cont_map() to restore the built-in default layout below.

Default JVS to cont_state_t mapping:

p1.start / p2.start -> CONT_START
p1.up / p2.up -> CONT_DPAD_UP
p1.down / p2.down -> CONT_DPAD_DOWN
p1.left / p2.left -> CONT_DPAD_LEFT
p1.right / p2.right -> CONT_DPAD_RIGHT
p1.sw16 / p2.sw16 -> CONT_A
p1.sw2 / p2.sw2 -> CONT_B
p1.sw1 / p2.sw1 -> CONT_X
p1.sw14 / p2.sw14 -> CONT_Y
p1.service / p2.service -> CONT_Z
panel.psw.test -> CONT_C
panel.psw.service -> CONT_D
wheel -> joyx (-128 to 127)
accel -> rtrig (0 to 255)
brake -> ltrig (0 to 255)

The default mapper skips wheel and pedals when wheel and accel raw values differ by no more than 0x500.

Typedef Documentation

◆ mie_cont_map_fn_t

typedef void(* mie_cont_map_fn_t) (const mie_jvs_inputs_t *jvs, cont_state_t *cont)

JVS inputs to Dreamcast controller mapper.

Installed with mie_set_cont_map(). Receives decoded native JVS state and fills a cont_state_t compatible structure for use with the standard controller API.

Parameters

jvs	Decoded JVS input state.
cont	Controller state to fill.

Function Documentation

◆ mie_set_cont_map()

void mie_set_cont_map ( mie_cont_map_fn_t fn )

Install a custom JVS-to-controller mapper.

Replaces the built-in default mapping applied during polling. Pass NULL to restore the default mapper documented in Controller Mapping.
