Function Documentation

◆ owb_rmt_initialize()

OneWireBus* owb_rmt_initialize	(	owb_rmt_driver_info *	info,
		gpio_num_t	gpio_num,
		rmt_channel_t	tx_channel,
		rmt_channel_t	rx_channel
	)

Initialise the RMT driver.

Parameters

[in]	info	Pointer to an uninitialized owb_rmt_driver_info structure. Note: the structure must remain in scope for the lifetime of this component.
[in]	gpio_num	The GPIO number to use as the One Wire bus data line.
[in]	tx_channel	The RMT channel to use for transmitting data to bus devices.
[in]	rx_channel	the RMT channel to use for receiving data from bus devices.

Returns: OneWireBus *, pass this into the other OneWireBus public API functions
