Want to learn to use the register output light emitting tube, in the final four tips to the main function pointer, where adjustment


# include "stm32f10x_gpio. H"

Int main ()

Which passes by brother to look at the bai

CodePudding user response:

Didn't see what problem, the include files is wrong

CodePudding user response:

Int main ( void

Keil arm programming is the virtue

CodePudding user response:

At present situation, the useless structure devices for compilation can be normal output light,
Change into the following four last sentence, the compiler will not complain, but no result
RCC (*). APB2ENR |=(1 & lt; <4);
(* GPIOC). The CRL & amp;=~ (0 x0f & lt; <4 * 6);
(* GPIOC). The CRL |=(1 & lt; <4 * 6);
(* GPIOC). The ODR |=(1 & lt; <6);

CodePudding user response:

Places they found the problem, the # define GPIOC (GPIO_TypeDef *) GPIOC_BASE without parentheses, and there will be no requirement pointer errors, there is no output for structure members in accordance with the manual in order to add, make the address of the structure is not enough, call address corresponding to the error, according to the order, after add compiled output is normal,
