Function Documentation

void os_delay_us

(

uint16

us

)

Delay function, maximum value: 65535 us.

Parameters

uint16

us : delay time, uint: us, maximum value: 65535 us

Returns

null

void os_install_putc1

(

void(*)(char c)

p

)

Register the print output function.

Attention

os_install_putc1((void *)uart1_write_char) in uart_init will set printf to print from UART 1, otherwise, printf will start from UART 0 by default.

Parameters

void(*p)(char

c) - pointer of print function

Returns

null

void os_putc

(

char

c

)

Print a character. Start from from UART0 by default.

Parameters

char	c - character to be printed

Returns

null
