Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (VCC) is within the range of 2.0V to 5.5V.
   • Connect the ground (GND) pin to a stable ground reference.

2. Clock Configuration:

   • The system clock can be configured using an internal RC oscillator or an external crystal oscillator.
   • For precise timing, use an external crystal oscillator with a frequency up to 48MHz.

3. GPIO Configuration:

   • Configure the GPIO pins as input or output using the appropriate registers.
   • Set the pin mode (push-pull, open-drain, etc.) as required.

4. ADC and DAC:

   • Initialize the ADC and DAC channels by configuring the corresponding control registers.
   • Use the ADC to convert analog signals to digital values and the DAC to generate analog signals from digital values.

5. Timers:

   • Configure the timers for various tasks such as generating PWM signals, measuring time intervals, or creating delays.
   • Use the timer interrupt to handle periodic events.

6. Communication Interfaces:

   • Initialize the UART, SPI, I2C, and USB interfaces by setting up the communication parameters (baud rate, data format, etc.).
   • Use the appropriate functions to send and receive data over these interfaces.

7. Interrupts:

   • Enable and configure interrupts using the NVIC.
   • Write interrupt service routines (ISRs) to handle specific events.

8. Low Power Modes:

   • Enter low power modes (Sleep, Stop, Standby) to reduce power consumption.
   • Use the wake-up sources (e.g., external interrupts, timer timeouts) to exit low power modes.

9. Programming and Debugging:

   • Use an in-circuit debugger or programmer to upload code to the flash memory.
   • Utilize the on-chip debugging features to monitor and control the microcontroller during development.
