9th LCSC Electronics Design Competition - Electronic Desktop Decoration

This comprehensive desktop temperature and humidity meter case study essentially combines all the previous modules into a single project. It uses two AAA batteries for power by default, and due to power consumption considerations, it's in sleep mode by default.
When a button is pressed, an interrupt is triggered, ending sleep mode, performing a button press check, acquiring the temperature and humidity readings, and starting the digital display. Simultaneously, a timer interrupt is started, displaying the data twice before returning to sleep, awaiting the next wake-up.
To detect battery voltage, ADC-related code can be added;
for timed readings, RTC real-time clock code can be added.
All code in this project is generated using STM32CubeMX, which by default generates corresponding files based on the peripherals. I recommend not modifying the overall project structure (as the code is small); simply write the relevant driver code directly in the corresponding peripheral files.
Finally, if you haven't studied the previous case study projects, I suggest reviewing them, especially the interrupts. The STM32G0 series uses the Arm Cortex M0+ core, a two-stage pipelined von Neumann architecture with a 4-bit interrupt priority. These are different from the STM32F103.
