STM32F030R8Tx HAL库使用flash和stop模式
-
准备工程，此例程在此链接的基础上添加的
https://blog.csdn.net/mygod2008ok/article/details/106978147
-
在工程中添加stm32f0xx_hal_flash.c,stm32f0xx_hal_flash_ex.c,
stm32f0xx_hal_pwr.c和stm32f0xx_hal_pwr_ex.c
-
在stm32f0xx_hal_conf.h中打开HAL_FLASH_MODULE_ENABLED和HAL_PWR_MODULE_ENABLED宏
-
在main.h中添加flash相关的宏

运行程序长按UP键产生UP_KEY_LONG事件，执行write_stop_mode_flag标志后复位，重新进入主程序会检查stop标志，如果
其读出的flash值是0xaa5533bb，说明需要进入stop模式
#define STOP_FLAG_VALUE 0xaa5533bb
