10. What are the design considerations when using GD32F303RGT6？
Software migration: When porting from STM32F103/F303, GD libraries are highly compatible, but pay attention to clock tree differences and Flash operation timing differences
Operating voltage: GD32 operates at 2.6V ~ 3.6V, narrower than STM32 (2.0V ~ 3.6V)
Frequency difference: GD32 runs at higher frequency (120MHz vs 72MHz) — delay and timing-related code may need adjustment
Flash layout: The GD32F303RGT6 has a "slow" Flash Bank — optimize layout for LVGL image and font resources
Noise immunity: In some applications, STM32 may have stronger noise immunity than GD32, especially in high-frequency signal environments
Debug interface: Supports both SWD and JTAG debug interfaces
Power decoupling: Place 100nF decoupling capacitors close to power pins; power traces should pass through capacitors before reaching MCU power pins
