DETAILS
Cortex M3 TimestampProvider delegate for use with xdc.runtime.Timestamp.
The SysTick timer is used as the timestamp source.

config TimestampProvider_configTimer  // module-wide
C synopsis target-domain
extern const Bool TimestampProvider_configTimer;
 
 
TimestampProvider_get32()  // module-wide

Return a 32-bit timestamp

C synopsis target-domain
Bits32 TimestampProvider_get32();
 
RETURNS
Returns a 32-bit timestamp value. Use getFreq to convert this value into units of real time.

TimestampProvider_get64()  // module-wide

Return a 64-bit timestamp

C synopsis target-domain
Void TimestampProvider_get64(Types_Timestamp64 *result);
 
ARGUMENTS
result — pointer to 64-bit result
This parameter is a pointer to a structure representing a 64-bit wide timestamp value where the current timestamp is written.
If the underlying hardware does not support 64-bit resolution, the hi field of result is always set to 0; see xdc.runtime.Types.Timestamp64. So, it is possible for the lo field to wrap around without any change to the hi field. Use getFreq to convert this value into units of real time.

TimestampProvider_getFreq()  // module-wide

Get the timestamp timer's frequency (in Hz)

C synopsis target-domain
Void TimestampProvider_getFreq(Types_FreqHz *freq);
 
ARGUMENTS
freq — pointer to a 64-bit result
This parameter is a pointer to a structure representing a 64-bit wide frequency value where the timer's frequency (in Hz) is written; see xdc.runtime.Types.FreqHz. This function provides a way of converting timestamp values into units of real time.

Common module configuration parameters

Configuration settings
TimestampProvider.common$ = Types.Common$ undefined;
 
DETAILS
All modules have this configuration parameter. Its name contains the '$' character to ensure it does not conflict with configuration parameters declared by the module. This allows new configuration parameters to be added in the future without any chance of breaking existing modules.
