Function Documentation

ri_uart_config()

rd_status_t ri_uart_config

(

const ri_uart_init_t *const

config

)

Configure UART.

Parameters

[out]

config

Interface used for communicating through uart.

Return values

RD_SUCCESS	on success.
RD_ERROR_NULL	Channel is NULL.

ri_uart_init()

rd_status_t ri_uart_init

(

ri_comm_channel_t *const

channel

)

Initialize UART.

This only setups the function interface, you must call ri_uart_config to setup pins, HWFC, baudrate tec.

Parameters

[out]

channel

Interface used for communicating through uart.

Return values

RD_SUCCESS	on success.
RD_ERROR_INVALID_STATE	if UART is already initialized.
RD_ERROR_NULL	Channel is NULL.

ri_uart_uninit()

rd_status_t ri_uart_uninit

(

ri_comm_channel_t *const

channel

)
