The PCF85063 RTC needs special treatment while setting or reading the time/date:
- when reading the 7 time/date registers they are blocked from updating by the 'one second' pulse internally. So reading all time/date registers should happen in one turn to ensure reading is an atomic operation - to let setting the time/date be an atomic operation as well, the clock dividers must be kept in reset state to avoid a 'one second' pulse during writing the 7 time/date registers Changes from v1: - using high level I2C access functions instead of the low level i2c_transfer() to simplify the code Comments are welcome Juergen Please keep me on CC since I'm not subscribed to the list.
