Problem working with SPL

[CircuitDigest]

Hey I find sduino as a great alternative for STVD and cosmic C compiler. Mainly because of the familiar Arduino IDE and easy code upload and serial monitor debugging option. So my plan is to use the IDE and compile SPL directly. I do not intend to use the existing Arduino functions or libraries I am only interested in the IDE and SPL.

I wrote a simple code to control GPIO pins, the code compiled and uploaded successfully but I was not able to get it working on the hardware. The same code (equivalent), when compiled on cosmic C, works fine. The code I used is as follows

`#define Green_LED GPIOA, GPIO_PIN_3 void setup() { GPIO_DeInit(GPIOA); //prepare Port A for working GPIO_DeInit(GPIOB); // prepare Port B for working

//Declare PA2 as input pull up pin GPIO_Init (GPIOA, GPIO_PIN_2, GPIO_MODE_IN_PU_IT);

//Declare PA3 as Push Pull Output pin GPIO_Init (Green_LED, GPIO_MODE_OUT_PP_LOW_SLOW);

//Declare PB5 as push pull Output pin GPIO_Init (GPIOB, GPIO_PIN_5, GPIO_MODE_OUT_PP_LOW_SLOW); }

void loop() { if (GPIO_ReadInputPin(GPIOA, GPIO_PIN_2)) //if button pressed GPIO_WriteLow(Green_LED); //LED ON else GPIO_WriteHigh(Green_LED); //LED OFF GPIO_WriteReverse(GPIOB,GPIO_PIN_5); delay (100); }`

I used the same code for Cosmic C and STVD, more info on that https://circuitdigest.com/microcontroller-projects/gpio-functions-on-stm8s-using-cosmic-c-and-spl-blinking-led-with-push-button

So what am I missing here? My best guess is something has messed up the clock settings?

you activate external interrupts on PA2, and use the default setting in the EXTI_CR1 register which is 00: falling edge and low level. So as soon as you pull PA2 low, the ISR for external ints gets continuously executed until you release the button

How to activate external interrupts on PA2 on stm8s103f3. Please explain with coding example ?
