Toggling GPIO's on STM32F429

[shaiko]

Hello,

I'm trying to make a led blink on the STM32F429 Discovery kit from ST.
https://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/DM00097320.pdf
I downloaded the firmware package from page 7 - figure 2 in the link above.

I'm use the following library from the package:
ST firmware\Projects\Template\EWARM.

The led I want to toggle is connected to "PG13".

How do I access it in C code ?

See if this works. Compiled for 8 MHz. mikroC PRO ARM code. Led blinks very one second.

This is the whole code?

void main() {
  GPIO_Digital_Output(&GPIOG_BASE, _GPIO_PINMASK_ALL); // Set PORTB as digital output
  
  GPIOG_ODR = 0;
  

  while(1) {
    GPIOG_ODR.B13 = ~GPIOG_ODR.B13;
    Delay_ms(1000);
  }
}

You didn't include any libraries?

 

[milan.rajik]

Ye, but it is mikroC PRO ARM Compiler code. To compile my code for different clock frequency just download and install the demo version of mikroC PRO ARM Compiler from mikroElektronika.

My goal is to understand exactly what happens - not just to make the LED blink.
Can you post the whole code please - with the initialization functions and the include statements.

 

[milan.rajik]

In post #2 I have provided the whole C code.

 

[shaiko]

I don't really understand...where are your include statements?
I'm using IAR...

 

[milan.rajik]

Please read the posts properly. The code I have posted is for "mikroC PRO ARM Compiler" and not IAR ARM. Please post your IAR ARM C Code. I will test it.

Problem solved.
I didn't initialize the GPIOs properly...
