下载源码

找到STM32F407的demos程序（`chibios\demos\STM32\RT-STM32F407-DISCOVERY`）

/* * This is a periodic thread that does absolutely nothing except flashing * a LED. */
    static THD_WORKING_AREA(waThread1, 128);
    static THD_FUNCTION(Thread1, arg) {
    
      (void)arg;
      chRegSetThreadName("blinker");
      while (true) {
        palSetPad(GPIOD, GPIOD_LED3);       /* Orange. 根据个人开发板配置*/
        chThdSleepMilliseconds(500);
        palClearPad(GPIOD, GPIOD_LED3);     /* Orange. */
        chThdSleepMilliseconds(500);
      }
    }
    
    /* * Application entry point. */
    int main(void) {
    
      /* * System initializations. * - HAL initialization, this also initializes the configured device drivers * and performs the board-specific initializations. * - Kernel initialization, the main() function becomes a thread and the * RTOS is active. */
      halInit();
      chSysInit();
    
      /* * Activates the serial driver 2 using the driver default configuration. * PA2(TX) and PA3(RX) are routed to USART2. */
      sdStart(&SD2, NULL); //SD2，代表UART2
      palSetPadMode(GPIOA, 2, PAL_MODE_ALTERNATE(7)); //UART TX
      palSetPadMode(GPIOA, 3, PAL_MODE_ALTERNATE(7)); //UART RX
    
      /* * Creates the example thread. 创建线程 */
      chThdCreateStatic(waThread1, sizeof(waThread1), NORMALPRIO, Thread1, NULL);
    
      /* * Normal main() thread activity, in this demo it does nothing except * sleeping in a loop and check the button state. */
      while (true) {
        if (palReadPad(GPIOA, GPIOA_BUTTON))
          TestThread(&SD2);
        chThdSleepMilliseconds(500);
      }
    }

使用烧写工具烧写。效果是串口不断打印TestThread中的信息，LED不断闪烁
