hm2_uart_send

NAME

hm2_uart_send — write data to a Hostmot2 UART

SYNTAX

int hm2_uart_send ( char *name, unsigned char data[], int count )

DESCRIPTION

hm2_uart_send write 'count' bytes of data to the UART "name" from the buffer 'data'.

The UART FIFO is 64 bytes deep, attempts to transmit more than 64 bytes may have unexpected effects.

"name" is a unique string given to each UART during hostmot2 setup.
The names of the available channels are printed to standard output during the driver loading process and take the form:
hm2_<board name>.<board index>.uart.<index>
For example
hm2_5i23.0.uart.0

This function performs writes of data to the specified UART.It should be used inside a function in a realtime or userspace HAL component.

RETURN VALUE

Returns the number of bytes sent on success and -1 on failure.
