在GD32F405VG开发板上移植RTThread系统

搭建GD32F405基础工程

创意脱衣机工程

[一]准备工作

1.1 创作文件夹 GD32F405_RTT 并创作文件目录

文件目录释义：

Application ---- 应用文件
Board ---- 版级相关文件
Driver ---- 驱动程序
Firmware ---- 生成固件
Library ---- 固件库
Project ---- 工程文件
System ---- rtt-thread源代码

1.2 添加固定文件到库

1.3 添加it.c systick.c到Board

1.4 添加main.c到Application

[二]创建工程

2.1 新建工程并选型号为GD32F405VG 新建工程目录

2.2 添加固定文件库文件

2.3 添加CMSIS文件

2.4 gd32f4xx_it.c systick.c 放入Board目录下

2.5 main放板目录下

2.6 工程配置

2.7 编译

2.8 配置系统时钟为HSE 12MHZ 配置滴答定时器中断为10ms触发(根据自己硬件来的)

2.8 添加测试代码在main.c中添加跑马灯测试程序

#include "gd32f4xx.h"
#include "systick.h"
#include <stdio.h>
static void RCC_Configuration(void);
#define LED_RCC RCU_GPIOE
#define LED_GPIO GPIOE

#define LED_Y_PIN GPIO_PIN_10
#define LED_G_PIN GPIO_PIN_11
int main(void)
{
//配置系统时钟时钟
RCC_Configuration();
//配置系统滴答定时器 10ms
systick_config();
rcu_periph_clock_enable(LED_RCC);

delay_1ms(100);
gpio_bit_reset(LED_GPIO, LED_G_PIN);
}
}
static void RCC_Configuration(void)
{
ErrStatus HSEStartUpStatus;
rcu_deinit();
rcu_osci_on(RCU_HXTAL);
HSEStartUpStatus = rcu_osci_stab_wait(RCU_HXTAL);
if (HSEStartUpStatus == SUCCESS)
{
rcu_ahb_clock_config(RCU_AHB_CKSYS_DIV1); // 24MHz
rcu_apb2_clock_config(RCU_APB2_CKAHB_DIV1); // 24MHz
rcu_apb1_clock_config(RCU_APB1_CKAHB_DIV2); // 12MHz
rcu_pll_config(RCU_PLLSRC_HXTAL, 12, 192, 8, 8);
rcu_osci_on(RCU_PLL_CK);
if (rcu_osci_stab_wait(RCU_PLL_CK) != SUCCESS)
{
while (1)
;
}
rcu_system_clock_source_config(RCU_CKSYSSRC_PLLP);
while (rcu_system_clock_source_get() != RCU_SCSS_PLLP)
{
}
}
}

添加RTT源代码(完整版)

[一]准备工作

1.1 准备一个dist 这里用的是GD32F450Z-EVAL的bsp 按图放好文件即可

把startup_gd32f4xx.s放在板文件夹下

[二]工程配置

2.1 删除源startup_gd32405.s 增加startup_gd32f4xx.s

2.2 添加源文件 src 文件夹下所有文件 不需要kconfig

2.3 新建工程目录 CPU —> 添加libcpu中的文件

2.4 配置RT-rhread
