nsdsp_session_send_uart

This function transmits data through UART.

Syntax

unsigned int nsdsp_session_send_uart(
        nsdsp_session_t   session,
        void*             data,
        unsigned int      size
);

Parameters

session - a reference to the Session Object

data - the buffer containing the data to transmit

size - the size of the data in bytes

Return

The function returns the amount of data transmitted in bytes, which may be less than size if a timeout occurs in the middle of the transmission.

If flow control is on and the external UART device blocks the transmission for a long time, the operation will time out.

Notes

This instruction only queues a command. The command will be sent to NSDSP when you queue enough commands to fill the buffer or when you call nsdsp_session_flush.

Supported session types: UART
