STM32: DS1307 RTC Clock (I2C)

Read the current time and date from a DS1307 real-time clock over I2C1 on the STM32 Blue Pill (SCL=PB6, SDA=PB7). The QEMU DS1307 slave returns the live system clock in BCD, ticking once a second in the Serial Monitor.

What you'll simulate

  • ✓Real Arduino Uno emulation — cycle-accurate, no hardware needed
  • ✓1 interactive component on the canvas
  • ✓Serial Monitor included — see output in real time
