hm2_uart_send - write data to a Hostmot2 UART
int hm2_uart_send(char* name, unsigned char data, int count)
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.
Returns the number of bytes sent on success and -1 on failure.
man hm2_uart_setup, man hm2_uart_read See src/hal/drivers mesa_uart.comp for an example usage.
