用最新板MDK库玩转智林STM32众所周知智林的板子是不用固件库的,本人想用库行不行,昨天一试还真行,且为最新的库,环境为
我只写了一个主程序,main.c 其余两个:一个启动代码,一个是编译过的库文件
程序十分简捷:我根本就没调直接用串口下载一次成功,不亦乐乎!
现把主程序传上来大家来分享:
#include "stm32f10x_lib.h"

void RCC_Configuration(void)
{
ErrorStatus HSEStartUpStatus;
// RCC system reset(for debug purpose)
RCC_DeInit();
// Enable HSE
RCC_HSEConfig(RCC_HSE_ON);
// Wait till HSE is ready
HSEStartUpStatus = RCC_WaitForHSEStartUp();
if(HSEStartUpStatus == SUCCESS)
{
// HCLK = SYSCLK
RCC_HCLKConfig(RCC_SYSCLK_Div1);
// PCLK2 = HCLK

FLASH_SetLatency(FLASH_Latency_0);
//FLASH_SetLatency(FLASH_Latency_1);
// Enable Prefetch Buffer
FLASH_PrefetchBufferCmd(FLASH_PrefetchBuffer_Enable);
// PLLCLK = 8MHz * 2 = 16 MHz
RCC_PLLConfig(RCC_PLLSource_HSE_Div1, RCC_PLLMul_2);
// Enable PLL
RCC_PLLCmd(ENABLE);
// Wait till PLL is ready
while(RCC_GetFlagStatus(RCC_FLAG_PLLRDY) == RESET)
{
}
// Select PLL as system clock source
RCC_SYSCLKConfig(RCC_SYSCLKSource_PLLCLK);
// Wait till PLL is used as system clock source
while(RCC_GetSYSCLKSource() != 0x08)
{
}
}
// Enable peripheral clocks --------------------------------------------------

void LedInit(void)

while(1)
{
GPIO_ResetBits(GPIOB,GPIO_Pin_5);
Delay(2000000);
GPIO_SetBits(GPIOB,GPIO_Pin_5);
Delay(2000000);
}
}
我把HEX文件和原main.c压缩,另两个是编译环境的只三个文件就实现了。呵呵
