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

( |
u16 |
uS |
) |
|
Waits for a specific number of uS
Example:
- Parameters:
-
[in] | uS | delay (1..65535 microseconds) |
- Returns:
- < 0 on errors
