Function Documentation

◆ MAXIM_RISCV_TIME_TIMER()

void MAXIM_IRQ_HANDLER MAXIM_TIME_HANDLER MAXIM_RISCV_TIME_TIMER ( void )

Time base timer interrupt handler.

◆ maxim_time_init()

int maxim_time_init ( void )

Start the timer used as the CPU1 time base.

Reserve the configured timer for CPU1 elapsed time.

Returns: 0 in case of success, -EIO if the timer could not be initialized.

◆ no_os_get_time()

struct no_os_time no_os_get_time ( void )

Get the time elapsed since the time base was started.

Get current time.

Returns: The elapsed time in seconds and microseconds.

◆ no_os_mdelay()

void no_os_mdelay ( uint32_t msecs )

Busy-wait for a number of milliseconds.

Wait until msecs milliseconds passed.

Parameters

msecs - Delay in milliseconds.

◆ no_os_udelay()

void no_os_udelay ( uint32_t usecs )

Busy-wait for a number of microseconds.

Wait until usecs microseconds passed.
