mie_coin_add()

bool mie_coin_add	(	uint8_t	slot,
		uint16_t	amount,
		bool	block )

mie_coin_decrease()

bool mie_coin_decrease	(	uint8_t	slot,
		uint16_t	amount,
		bool	block )

Send JVS COINDEC (0x30) for a coin slot.

Subtracts credits from the specified coin slot meter on the JVS board.

Parameters

slot	Coin slot index (0 = first slot).
amount	Credits to subtract.
block	true to wait for completion; false to queue only.

Return values

true	Command completed or queued successfully.
false	Invalid arguments, JVS not initialized, busy, or I/O failed.

(
