STM CircleOS forum / GPIOD undeclared

nishant · 2009-07-27 12:44:22

Hi all,
In Primer2_mouse project, I am getting error "GPIOD undeclared". I tried including all the necessary files and tried declaring as given in 'STM32 Firmware Library' pdf also but didn't work.
What could be the reason?

Hello,

There is on of the config header files to the library you need to uncomment that line...

use find in file to find the file.

I have made sure that stm32f103x_map.h, stm32f103x_conf.h and all the related header files are included in the application.c.
But still I am getting the error: 'GPIOD' undeclared (first use in this function) in application.c
and I have not yet to found out the reason.

I guess you have to edith this file:
stm32f10x_conf.h

Check the the line is not commented out:
#define _GPIO
#define _GPIOA
#define _GPIOB
#define _GPIOC
#define _GPIOD
#define _GPIOE
//#define _GPIOF
//#define _GPIOG

Thanks a lot. It worked. That line was commented.
Can you suggest which other projects I can study to particularly understand & learn using GPIO?

Thanks.

I guess you should look here:

Good luck.
