【AT-START-F407测评】RT-Thread 点LED, 顺便报RT Studio Reflash的BUG
RT-Thread 点LED, 顺便报RT Studio Reflash的BUG1, 参见 @tlled 仁兄的帖子，做了一个LED点灯程序。
下载最新的RT Studio，导入SDK。
这个IDE 2.0已经做得很方便了，通过简单几个选项，模板化自动生成可以run的例程。
2，需要手工添加LED程序led.
代码片断贴在这里，所有代码打包见附件。
led.h#ifndef LED_H_
#define LED_H_
#include <drv_gpio.h>
#define LED2_PIN GET_PIN(D,13) // PD13
#define LED3_PIN GET_PIN(D,14) // PD14
#define LED4_PIN GET_PIN(D,15) // PD15
int led_init(int led);
int led_on(int led);
int led_off(int led);
int led_toggle(int led);
#endif // LED_H_
led.c
#include <rtdevice.h>// RT-Thread pin 设备需要包含此头文件
#include "led.h"
int led_init(int led)
{
/* LED 引脚为推挽输出模式*/
rt_pin_mode(led, PIN_MODE_OUTPUT);
return 0;
}
int led_on(int led)
{
/* API 输出低电平 */
rt_pin_write(led, PIN_LOW);
return 0;
}
int led_off(int led)
{
/* API 输出高电平 */
rt_pin_write(led, PIN_HIGH);
return 0;
}
int led_toggle(int led)
{
/* API 读出当前电平 然后输出相反电平 */
rt_pin_write(led, !rt_pin_read(led));
return 0;
}
当然还有main.c

#include <rtthread.h>
#define DBG_TAG "main"

#include <rtdbg.h>
#include "led.h"
#if 0
int main(void)
{
int count = 1;
while (count++)
{
LOG_D("Hello RT-Thread!");
rt_thread_mdelay(1000);
}
return RT_EOK;
}
#else
int main(void)
{
int count = 1;
/* user app entry */
led_init(LED2_PIN);
led_init(LED3_PIN);
led_init(LED4_PIN);
led_on(LED2_PIN);
led_on(LED3_PIN);
led_on(LED4_PIN);
while (count++)
{
LOG_D("Hello RT, Red!");
led_toggle(LED2_PIN);
rt_thread_mdelay(500);
LOG_D("Hello RT, Yellow!");
led_toggle(LED3_PIN);
rt_thread_mdelay(500);
LOG_D("Hello RT, Green!");
led_toggle(LED4_PIN);
rt_thread_mdelay(1000);
LOG_D("Hello RT-Thread! Next One!");
}
return RT_EOK;
}
#endif
3，在Download Reflash的过程中，确实发现第一次Download成功之后，无法继续Download的情况，
多次试验后，发现和Erase过程强相关，感觉是Erease memory没有处理干净。
start download flash :2021-01-28 15:47:16

只能通过别的过程把Flash擦除干净之后，才能正常下载。
4，另外一个问题是编译返回码错误，编译成功了，返回值（-1）
16:39:47 **** Incremental Build of configuration Debug for project at32f407vgt7_hello ****

5，最后，RT点亮的RYG三色灯是这样的？串口输出一并贴出。
