[Atlanta AT-START-F437 Review] -01- Unboxing and lighting [Copy link]

 

I'm a little embarrassed. I just received a call from EEword saying that my trial version was approved while I was on a business trip. I was on a business trip for 18 days and just returned to Chengdu yesterday. I'll do an unboxing here and make up for the evaluation report I owed before.

First, let’s take a photo and say hello to everyone.

The entire board has a USB interface, an Ethernet interface, an onboard DAP downloader, indicator lights and buttons, which are completely sufficient for general development, and the derived IO can be expanded to your full imagination.

You can take a look at this for the overall peripheral interface. I think I don’t have all of them, right?

Of course, you can also go to the official website to download the operating instructions of this board. For details, jump here: Operating Instructions Document

The above introduces the board, let’s light a lamp below, it’s simple.

(Added in the evening), I went to cook after work

I originally planned to work overtime at night, but I accidentally fell asleep... so I'll just update it today.

According to the schematic diagram, the pins of the LED are: PD13, PD14, PD15 as shown below

I started lighting the lamp directly. According to the original LED routine, I transplanted the project and configured the clock.

#include "at32f435_437_clock.h"
#include "DRV_Delay.h"


/*----------------
-- 初始化LED引脚--
*/
void LED_Init(void)
{
  gpio_init_type gpio_init_struct;
  crm_periph_clock_enable(CRM_GPIOD_PERIPH_CLOCK, TRUE );  /* enable the led clock */
  crm_periph_clock_enable(CRM_GPIOD_PERIPH_CLOCK, TRUE );
  gpio_default_para_init(&gpio_init_struct);/* set default parameter */
  gpio_init_struct.gpio_drive_strength = GPIO_DRIVE_STRENGTH_STRONGER;  /* configure the led gpio */
  gpio_init_struct.gpio_out_type  = GPIO_OUTPUT_PUSH_PULL;
  gpio_init_struct.gpio_mode = GPIO_MODE_OUTPUT;
  gpio_init_struct.gpio_pins =GPIO_PINS_13 |GPIO_PINS_14|GPIO_PINS_15;
  gpio_init_struct.gpio_pull = GPIO_PULL_NONE;
  gpio_init(GPIOD, &gpio_init_struct);
}


void LED_Flash(void)
{
	    //--点亮
	    gpio_bits_reset(GPIOD,GPIO_PINS_13);
		gpio_bits_reset(GPIOD,GPIO_PINS_14);
		gpio_bits_reset(GPIOD,GPIO_PINS_15);
		Delay_ms(100);
	    //--关闭
		gpio_bits_set(GPIOD,GPIO_PINS_13);
		gpio_bits_set(GPIOD,GPIO_PINS_14);
		gpio_bits_set(GPIOD,GPIO_PINS_15);
		Delay_ms(100);

	
	    //--点亮
	    gpio_bits_reset(GPIOD,GPIO_PINS_13);
		gpio_bits_reset(GPIOD,GPIO_PINS_14);
		gpio_bits_reset(GPIOD,GPIO_PINS_15);
		Delay_ms(400);
	    //--关闭
		gpio_bits_set(GPIOD,GPIO_PINS_13);
		gpio_bits_set(GPIOD,GPIO_PINS_14);
		gpio_bits_set(GPIOD,GPIO_PINS_15);
		Delay_ms(400);
}

int main(void)
{
	system_clock_config();
	Delay_init();
	LED_Init();
	while(1)
	{
		LED_Flash();
	}
}

This directly realizes the three lights flashing quickly for 100ms and slowly flashing for 400ms, a total of 1s. Let's take a look at the effect. I wonder if it is possible to upload the video.

The host is a good man. He cooks for himself after get off work.

The best thing to do is to taste it yourself

The unboxing is very exciting. The article is professional and is a good example for us to learn from!

Don't be so modest. I saw you next door. You always sign in with full attendance and must have received so many awards that your hands are cramping.

Only two months, that is the CH307 board, I want one, hahaha

Excellent unboxing post.
