Instructions for Use
Power Supply:
- Ensure that the VDD, VDDA, and VDDIO pins are connected to a stable power supply within the operating voltage range (2.0V to 3.6V).
- Connect the VSS pin to ground.
Clock Configuration:
- The internal high-speed oscillator (HSI) is enabled by default at 8 MHz.
- For higher precision, an external crystal or ceramic resonator can be connected to the HSE pins.
- Use the System Configuration (SYSCFG) register to configure the clock sources and prescalers.
Reset and Wake-up:
- The NRST pin can be used to reset the microcontroller.
- Wake-up from low power modes can be achieved using various events such as external interrupts, RTC alarms, or watchdog timers.
Peripheral Configuration:
- Configure the GPIO pins for input, output, or alternate functions using the GPIO configuration registers.
- Initialize communication interfaces (USART, SPI, I2C, USB) by setting up the corresponding control registers.
Low Power Modes:
- Enter Sleep mode by setting the SLEEPDEEP bit in the Cortex-M3 System Control Register (SCR).
- Enter Stop mode by configuring the Power Control (PWR) register and setting the PDDS bit.
- Enter Standby mode by setting the PDDS bit and the WFI (Wait For Interrupt) instruction.
Programming and Debugging:
- Use a JTAG/SWD debugger to program and debug the microcontroller.
- The SWDIO and SWCLK pins are used for debugging.
- Flash memory programming can be done through the bootloader or via a programmer.
ADC and DAC:
- Configure the ADC and DAC channels using the ADC and DAC configuration registers.
- Enable the ADC/DAC and start conversions as needed.
Timers:
- Set up the timer prescalers, auto-reload values, and interrupt enables in the timer control registers.
- Start the timers and handle timer interrupts as required.
RTC:
- Configure the RTC prescaler and alarm settings.
- Enable the RTC and use it for timekeeping or wake-up events.
Interrupt Handling:
- Configure the NVIC (Nested Vectored Interrupt Controller) to set priority levels and enable interrupts.
- Write interrupt service routines (ISRs) to handle specific interrupts.
