邁開探索429的第一步。
0) 用usb type A to mini B 線連線電腦和班子上的USB ST-LINK
1)下載stsw-stm32138.zip 解壓出 E:\stf429\STM32F429I-Discovery_FW_V1.0.1\Projects
2)用keil 開啟E:\stf429\STM32F429I-Discovery_FW_V1.0.1\Projects\Template\MDK-ARM下面的模板工程Template.uvproj
3)在main.c中新增程式碼如下:
void Delay(__IO uint32_t nTime)
{
while(--nTime != 0);
}
/**
* @brief Main program
* @param None
* @retval None
*/
int main(void)
{
/*!< At this stage the microcontroller clock setting is already configured,
this is done through SystemInit() function which is called from startup
files (startup_stm32f429_439xx.s) before to branch to application main.
To reconfigure the default setting of SystemInit() function, refer to
system_stm32f4xx.c file
*/
/* Add your application code here */
STM_EVAL_LEDInit(LED4);
/* Infinite loop */
while (1)
{
STM_EVAL_LEDToggle(LED4);
Delay(1900000);
}
}
4)Project 選單Bulid 編譯,Debug選單啟動除錯(start debug session ) 點run 執行程式。
5)led 開始閃爍。
如不能正常下載執行程式注意如下設定 Options for Target ‘Template'
