Function Documentation

◆ delay_ms()

__STATIC_FORCEINLINE void delay_ms ( uint32_t  number_of_ms)

Function for delaying execution for number of milliseconds.

Note
GR55xx is based on ARM Cortex-M4, and this fuction is based on Data Watchpoint and Trace (DWT) unit so delay is precise.
Function internally calls delay_us so the maximum delay is the same as in case of delay_us.
Parameters
number_of_msThe maximum delay time is about 67 seconds in 64M system clock. The faster the system clock, the shorter the maximum delay time.

◆ delay_us()

__STATIC_FORCEINLINE void delay_us ( uint32_t  number_of_us)

Function for delaying execution for number of microseconds.

Note
GR55xxx is based on ARM Cortex-M4, and this fuction is based on Data Watchpoint and Trace (DWT) unit so delay is precise.
Parameters
number_of_usThe maximum delay time is about 67 seconds in 64M system clock. The faster the system clock, the shorter the maximum delay time.
