Function Documentation

s32 MIOS32_DELAY_Init ( u32  mode  ) 

Initializes the Timer used by MIOS32_DELAY functions
This function has to be executed before wait functions are used (already done in main.c of the programming model)

Currently the freerunning timer (RIT) is allocated by MIOS32_DELAY functions

Parameters:
[in] mode currently only mode 0 supported
Returns:
< 0 if initialisation failed

Initializes the Timer used by MIOS32_DELAY functions
This function has to be executed before wait functions are used (already done in main.c of the programming model)

Currently TIM1 is allocated by MIOS32_DELAY functions - if this clashes with your application, just switch to another timer by overriding MIOS32_DELAY_TIMER and MIOS32_DELAY_TIMER_RCC in your mios32_config.h file

Parameters:
[in] mode currently only mode 0 supported
Returns:
< 0 if initialisation failed
s32 MIOS32_DELAY_Wait_uS ( u16  uS  ) 

Waits for a specific number of uS
Example:

   // wait for 500 uS
   MIOS32_DELAY_Wait_uS(500);
Parameters:
[in] uS delay (1..65535 microseconds)
Returns:
< 0 on errors
