Power Supply Configuration
- Ensure the supply voltage is within the specified range (1.71 V to 3.6 V).
- Connect a stable power source and ensure proper decoupling capacitors are used near the power pins.
Clock Configuration
- Configure the internal or external clock sources as per application requirements.
- Use the System Configuration Tool (SysConfig) or HAL libraries for setting up the clock tree.
Peripheral Initialization
- Initialize required peripherals using the provided HAL or LL (Low-Level) libraries.
- Refer to the reference manual for specific peripheral configurations like ADC, DAC, timers, etc.
Programming and Debugging
- Use an ST-LINK programmer/debugger for firmware development.
- Utilize IDEs like STM32CubeIDE for writing and debugging code.
- Leverage the debug interfaces (SWD, JTAG) for troubleshooting and development.
Memory Management
- Optimize the use of Flash and SRAM based on application needs.
- Implement efficient data handling practices to maximize performance.
Security Features
- Enable cryptographic accelerators and secure boot features if security is a concern.
- Configure the random number generator for secure key generation.
Thermal Management
- Ensure the device operates within the specified temperature range.
- Provide adequate cooling solutions if operating in high-temperature environments.
