Posted on September 06, 2013 at 14:32I'm trying to calibrate the difference of 512Hz at the out where PC13 possess 511.936Hz which causes about 10 seconds per day delay in the RTC. I'm making the form below, I wonder where I'm going wrong, not because it was effective, I do not find application notes with the correct sequence programming
// ((511.936-511.968)/511.9868) x 1 E06 = -62,5
// Looking in calibration table, the nearest compensation value is 65
// And then:
status_error = RTC_CoarseCalibConfig(RTC_CalibSign_Positive, 65);
status_error = RTC_CoarseCalibCmd(ENABLE);
Does not effect !!!!!!! Somebody help me
