完善我的文章《MCU BSP Driver分层设计》，本次提供GPIO控制驱动。
本片完成了GPIO控制驱动操作。
本人是基于野火指南者STM32开发板。
本驱动基于STM32F10X官方固件库。
主程序
int main(void)
{
WHT_LED_Init_Config();
for(;;)
{
WHT_LED_Color_Set(LED_RED);
Delay(500);
WHT_LED_Color_Set(LED_GREEN);
Delay(500);
WHT_LED_Color_Set(LED_BLUE);
Delay(500);
WHT_LED_Color_Set(LED_RGBOFF);
Delay(100);
}
}
