ContentsWhy GCC toolchain
Setting up GCC toolchainYou have two choices:
OR
Using IDE(Integrated Development Environment)I prefer Eclipse, but you have multiple choices, like
Testing Program: Blink#include "stm32f10x.h"
#include "stm32f10x_gpio.h"
#include "stm32f10x_rcc.h"
int main(void) {
int i;
GPIO_InitTypeDef GPIO_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStructure);
while (1) {
GPIO_SetBits(GPIOA, GPIO_Pin_8);
/* delay */
for (i = 0; i < 0x1000000; i++)
;
GPIO_ResetBits(GPIOA, GPIO_Pin_8);
/* delay */
for (i = 0; i < 0x1000000; i++)
;
}
