Instructions

1. Power Supply:

   • Connect V_DD to a stable power supply between 1.8V and 3.6V.
   • Ensure a low-impedance path to ground for proper operation.

2. Clock Configuration:

   • The internal high-speed oscillator (HSI) runs at 16 MHz by default.
   • For external clock sources, configure the clock control register (CLK_CKDIVR) and clock switch register (CLK_SWCR).

3. Low Power Modes:

   • Use the power control registers (PWR_CR and PWR_CSR) to enter low power modes such as Stop, Standby, and Sleep.
   • Ensure that wake-up sources are configured before entering low power modes.

4. GPIO Configuration:

   • Configure GPIO pins using the GPIO configuration registers (GPIOx_CR1, GPIOx_CR2, GPIOx_ODR, etc.).
   • Set the mode (input/output), speed, and pull-up/pull-down resistors as needed.

5. ADC Usage:

   • Initialize the ADC using the ADC control registers (ADC_CR1, ADC_CR2, ADC_CSR, etc.).
   • Select the channel and start a conversion using the appropriate commands.

6. UART/SPI/I²C Communication:

   • Configure the communication peripherals using their respective control registers (e.g., USART_CR1, USART_BRR, SPI_CR1, I2C_CR1).
   • Set baud rates, data formats, and other parameters as required.

7. Timer Configuration:

   • Initialize timers using the timer control registers (TIMx_CR1, TIMx_PSC, TIMx_ARR, etc.).
   • Configure prescalers, auto-reload values, and interrupt sources.

8. Interrupt Handling:

   • Enable and configure interrupts using the NVIC (Nested Vectored Interrupt Controller) and the appropriate interrupt enable registers.
   • Write interrupt service routines (ISRs) to handle specific events.

9. Flash Programming:

   • Use the Flash control registers (FLASH_CR1, FLASH_NCR1, etc.) to program and erase flash memory.
   • Ensure that write operations are properly sequenced and that the flash memory is not corrupted.

10. Reset and Initialization:

    • After reset, the microcontroller starts execution from the reset vector.
    • Initialize all necessary peripherals and system configurations in the main function or startup code.
