Instructions for Use:

1. Power Supply Requirements:

   • Ensure the supply voltage is within the specified range (1.8V to 3.6V). Use appropriate voltage regulators if necessary.

2. Clock Configuration:

   • Configure the system clock using the internal or external oscillators as per application requirements. The maximum clock speed is 72 MHz.

3. Flash Programming:

   • Program the flash memory using an ST-LINK/V2 programmer or any compatible tool. Follow the programming guidelines provided in the datasheet.

4. Peripheral Initialization:

   • Initialize required peripherals such as UART, SPI, I2C, etc., using the initialization functions provided by the HAL library or directly through register manipulation.

5. Low Power Mode:

   • Implement low power modes like Sleep, Stop, or Standby as needed to optimize power consumption. Refer to the power management section in the reference manual.

6. Interrupt Handling:

   • Set up interrupt handlers for various events (e.g., timer overflow, ADC conversion complete) to ensure responsive and efficient operation.

7. Capacitive Touch Sensing:

   • Utilize the capacitive touch sensing feature by configuring the GPIOs and using the dedicated library functions for touch detection.

8. Debugging:

   • Use the on-chip debug unit with SWD interface for debugging purposes. Connect an ST-LINK debugger for code stepping and breakpoint setting.

For detailed configuration and advanced usage, refer to the official STM32F334R8T6 datasheet and reference manual available from STMicroelectronics.
