#define PRINT_EXECUTION_SPEED

(

)

Value:

for(unsigned int __time=sys_get_uptime_us(); __time!=0; \
                                    printf("   Finished in %u us\n", (unsigned int)sys_get_uptime_us()-__time),__time=0)

Macro that can be used to print the timing/performance of a block Example:

PRINT_EXECUTION_SPEED()
{
    // ...
}
// At the end, the time taken between this block will be printed

Function Documentation

void delay_ms

(

unsigned int

milli_sec

)

Delays in milliseconds

Parameters

milli_sec

The delay in milliseconds.

If FreeRTOS is running, we should sleep the calling task instead of polling using the full CPU.

void delay_us

(

unsigned int

micro_sec

)

Delays in microseconds

Parameters

micro_sec

The delay in microseconds

char is_freertos_running

(

)

Returns

non-zero result if FreeRTOS is running

void log_boot_info

(

const char *

)

Logs CPU boot information to the Storage "boot.csv" is appended with the time this function is called
