S35190 3-wire RTC clock library for STM8003F3U6

S35190  is  a   3-wire  real-time  clock  IC with automatic time correction feature (hardware compensation). This is very useful option because  most  of  RTC crystals are not precise and require calibration or external  trimmer capacitor.

 

This simple  library  was  developed  on  STVD  4.3.6, built with Cosmic compiler. Reads/writes year, date & time, UART is pushing out the data.
