LPC54102 uses IRC and SPI communication without problems; but when using 32.768KHz and PLL to 12MHz, the program runs for a while and an exception error occurs....
How can we get the accurate time value? Using a single-chip microcomputer timer is definitely not an option. Now I use DS1302, but the error is too large, with an error of several seconds per day.1. I...
