Basic Instructions for STM32G474RET6

1. Power Supply:

   • Connect Vdd to the power supply (1.7 to 3.6V).
   • Ensure Vss is connected to ground.
   • Use decoupling capacitors (e.g., 100nF and 10uF) close to the power pins to stabilize the supply.

2. Clock Configuration:

   • Configure the system clock using the internal HSI (16 MHz) or external HSE (4 to 48 MHz).
   • Use the PLL to achieve the desired clock frequency (up to 170 MHz).

3. GPIO Initialization:

   • Enable the GPIO clock in the RCC (Reset and Clock Control) register.
   • Configure the GPIO mode (input, output, alternate function, analog).
   • Set the output type (push-pull, open-drain).
   • Configure the speed and pull-up/pull-down resistors.

4. Peripheral Initialization:

   • Enable the peripheral clock in the RCC register.
   • Configure the peripheral settings (e.g., baud rate for UART, prescaler for timers).
   • Initialize the peripheral using the appropriate initialization functions.

5. Interrupt Handling:

   • Enable the interrupt in the NVIC (Nested Vectored Interrupt Controller).
   • Write the interrupt service routine (ISR) for the specific interrupt.
   • Set the priority of the interrupt if necessary.

6. Low Power Modes:

   • Enter low power modes (Sleep, Stop, Standby) using the PWR (Power Control) register.
   • Configure the wake-up sources (e.g., EXTI lines, RTC alarms).

7. Flash Programming:

   • Use the HAL (Hardware Abstraction Layer) library or direct register manipulation to program the flash memory.
   • Ensure the flash write protection is configured correctly.

8. Debugging:

   • Connect a debugger (e.g., ST-Link) to the SWD (Serial Wire Debug) interface.
   • Use an IDE (e.g., STM32CubeIDE) to upload and debug the code.
