RTCResult RTC_SetDateTimeAsync(
const RTCDate* date,
const RTCTime* time,
RTCCallback callback,
void* arg );
date |
Pointer to the buffer storing date data. |
time |
Pointer to the buffer storing time data. |
callback |
Pointer to the callback function. This callback is called from within the interrupt handler. |
arg |
Argument to pass to the callback function. |
If the request succeeds, it returns 0. If the request fails, it returns some numeric value other than 0.
This function asynchronously writes date and time data to the real time clock. It sends date and time data to ARM7 and returns the process result without waiting for a response from the processor. If this function fails, no operation is performed and no user callback function is called.
Do not define parameter values of nonexistent dates or times. However, you may specify a day of the week that does not match the actual calendar. This function requires a PXI interrupt for synchronization. Values are written to the variables specified by the date
and time
arguments asynchronously with respect to the function.Because applications cannot change the date, use this API only for debugging during development.
