Thanks

I am new to STM microcontroller and am trying to program STM32G030F6P6TR using Arduino IDE.
I am using the latest version of IDE as well as latest version of STM32 libraries.
Here is the code I am trying to flash

#define SCR_Pin PA7
#define RELAY_PIN PC15
#define LED_PIN PA6
#define ZCD_PIN PA0 ...
