STM32 has RTC module built-in and it is easy and cheap to build decent clock without any extra modules

Connections to LCD:
#1 RST - PA0
#2 CS/CE - PA4
#3 DC - PA1
#4 MOSI/DIN - PA7
#5 SCK/CLK - PA5
#6 VCC - 3.3V
#7 LIGHT - 200ohm to GND
#8 GND

Currently I'm porting my datalogger project to STM32 MCU. Stay tuned for future videos.
