To verify the functionality of the STM32F103C8T6 (U1), you need to perform a series of steps that involve powering up the microcontroller, configuring its peripherals, and running test codes to ensure all functions as expected. Below is a detailed step-by-step plan:
Step 1: Initial Setup
  • 1.1 Power Supply Connections:
    • Connect VDD (pins 24, 36, 48) to a +3.3V power supply.
    • Connect VSS (pins 7, 23, 35, 47) to ground.
    • Connect VDDA (pin 9) to a +3.3V analog power supply for ADC operations.
    • Connect VSSA (pin 8) to analog ground.
    • Ensure decoupling capacitors (for example, 100nF) are close to VDD and VSS pins.
  • 1.2 Clock Configuration:
    • Connect a 8MHz crystal to PC14 (pin 3) and PC15 (pin 4) for an external oscillator.
    • Add two 22 pF capacitors from each of PC14 and PC15 to ground for oscillator stability.
Step 2: Boot Mode Setting
  • 2.1 Set BOOT0 (pin 44) to VDD for system memory boot mode.
    • Connect BOOT0 (pin 44) to 3.3V.
    • This setting allows you to use the internal bootloader of the STM32 to program it via USART or USB, which is practical for initial firmware upload.
Step 3: Programming Interface Setup
  • 3.1 Serial Wire Debug (SWD) Interface Configuration:
    • Connect PA13 (pin 34) to SWDIO.
    • Connect PA14 (pin 37) to SWCLK.
    • Use an ST-Link debugger/programmer to connect these pins for programming and debugging purposes.
Step 4: Programming and Testing
  • 4.1 Upload a Simple Blink LED Program:
    • Write or obtain a simple program to blink an LED connected to a GPIO pin (for example, PA5).
    • Program U1 using the ST-Link connected to the SWD interface.
  • 4.2 Verify Blinking LED:
    • Ensure the LED connected to PA5 (pin 15) blinks according to your program. This indicates that the MCU is programmed successfully and operates correctly.
Step 5: Final Verification
  • 5.1 Serial Communication Test:
    • Connect PA9 (pin 30) to a USB-to-serial adapter TX pin.
    • Connect PA10 (pin 31) to the adapter's RX pin.
    • Implement a simple echo program that sends back any received data.
    • Verify the communication using a serial terminal on your computer.
Step 6: Peripheral Test (Optional)
  • 6.1 ADC Verification:
    • Write a program to read an analog value on PA0 (pin 10) and output the digital conversion result through serial communication.
    • Connect a variable voltage source (e.g., a potentiometer with 3.3V) to PA0 and monitor the change in output data.
Additional Notes
  • It's crucial to carefully monitor the power supply and signal connections throughout these tests to avoid potential damage to the MCU.
  • After these basic steps, proceed with testing additional peripherals and functionalities as required by your specific project needs.
This plan provides a systematic approach to verifying the basic functionality of STM32F103C8T6 (U1). Adjustments may be required based on your particular setup and application requirements.
