A minor RTC defect at the example of LPCUSBlib_MassStorageHost in LPCOpen 2.2?

In the example of LPCUSBlib_MassStorageHost in LPCOpen 2.2, it seems to me that there is a minor defect at setting RTC (time will be used in FAT32).

int rtc_initialize (void)
{
...
Chip_RTC_SetFullAlarmTime(LPC_RTC, &rtcTime);

...

}

It should be

int rtc_initialize (void)
{
...
Chip_RTC_SetFullTime(LPC_RTC, &rtcTime);

...

}

Hi Jeremy,

yes, you're right.

the rtc function will be used in filesystem. if you create or modify a file, the file's new time stamp will use the rtc values.

thank you!

Have a great day,
Sol
