GD32F310G8开发板试用-USART、TIMER

首发极术社区。如对兆易创新GD32F310 MCU感兴趣，欢迎添加微信 aijishu2020 加入GD32技术讨论群。

PC端:WIN10
开发软件：Keil 5.26
开发板：GD32F310G8

一、搭建环境出现的问题

1、pack包下载和安装。
下载链接:http://www.gd32mcu.com/cn/download/7?kw=GD32F3

2、pack包打开的2种方法。

①、双击，一般都会有反应，但是我电脑没反应，可能是运行内存或者磁盘内存不够了。然后我就去keil安装目录下用packUnzip.exe来安装

②、使用pack install导入的方法

3、找不到GD32的对应flash算法
安装pack包好了之后就下载一个官方写好的LED例程，看能不能烧写进去，但是这是候又有问题了，就是找不到GD32的对应flash算法了。
就pack包也安装好了，下载的仿真器GD-LINK也连接上了，就是没有对应芯片的下载算法，就离谱。。。。。。搞了我好久。。。

然后就百度搜呀搜，然后看到其它的什么其它flash算法文件在这个文件路径下面

然后我灵光一闪，我不是可以把GD32的flash算法文件考到这下面就行了。
然后它就被我硬生生从这里

拷到了这里

然后它就出现了

然后下载就行了

淦，一个简单的东西让我搞了这么久，让我还以为是别人一直说的版本问题，还好我没下。

二、USART
①、PA9-Tx、PA10-Rx串口功能配置

void uart_init(void){//使能时钟rcu_periph_clock_enable(RCU_GPIOA);rcu_periph_clock_enable(RCU_USART0);//rcu_periph_clock_enable(RCU_AF);//Tx PA9 复用推挽输出gpio_mode_set(GPIOA,GPIO_MODE_AF,GPIO_PUPD_PULLUP,GPIO_PIN_9);    gpio_output_options_set(GPIOA, GPIO_OTYPE_PP, GPIO_OSPEED_50MHZ, GPIO_PIN_9);//RxPA10gpio_mode_set(GPIOA,GPIO_MODE_AF,GPIO_PUPD_PULLUP,GPIO_PIN_10);gpio_output_options_set(GPIOA, GPIO_OTYPE_PP, GPIO_OSPEED_50MHZ, GPIO_PIN_10);nvic_irq_enable(USART0_IRQn,0,0);gpio_af_set(GPIOA,GPIO_AF_1,GPIO_PIN_9|GPIO_PIN_10);/*USART 设置*/usart_deinit(USART0);usart_baudrate_set(USART0,115200);usart_word_length_set(USART0,USART_WL_8BIT);usart_stop_bit_set(USART0,USART_STB_1BIT);usart_parity_config(USART0,USART_PM_NONE);usart_hardware_flow_rts_config(USART0,USART_RTS_DISABLE);usart_hardware_flow_cts_config(USART0,USART_CTS_DISABLE);usart_receive_config(USART0,USART_RECEIVE_ENABLE);usart_transmit_config(USART0,USART_TRANSMIT_ENABLE);usart_enable(USART0);usart_interrupt_enable(USART0,USART_INT_RBNE);usart_interrupt_enable(USART0, USART_INT_IDLE);  /* 使能USART0空闲中断 */}

②、串口中断函数

uint16_t t=0;void USART0_IRQHandler(void){if(RESET!=usart_interrupt_flag_get(USART0,USART_INT_FLAG_RBNE)){gd_led_toggle();t=usart_data_receive(USART0);//接收数据//usart_data_transmit(USART0,USART_RX[t]);//usart_interrupt_disable(USART0,USART_INT_RBNE);usart_data_transmit(USART0,t);}else if(RESET!=usart_interrupt_flag_get(USART0,USART_INT_FLAG_IDLE)){usart_interrupt_disable(USART0,USART_INT_IDLE);}}

③、串口打印函数

//#include//printf("Hello,GD32F310G8");/* retarget the C library printf function to the USART */int fputc(int ch, FILE *f){    usart_data_transmit(USART0, (uint8_t) ch);    while(RESET == usart_flag_get(USART0, USART_FLAG_TBE));    return ch;}

④、硬件连接

三、TIMER1实现LED闪烁
①、定时器配置

//定时器初始化和配置//arr：重装载值  prescaler：预分频值////72MHz/(prescaler/2)*arr(5000)=1000msvoid gd_timer0_config(uint32_t arr,uint16_t prescaler){timer_parameter_struct timer0initpara;    /* enable the timer0 clock */    rcu_periph_clock_enable(RCU_TIMER1);//挂在AHB=72MHz上面    /* 初始化timer0 定时器参数，设置自动重装载值，分频系数，计数方式 */timer0initpara.clockdivision=TIMER_CKDIV_DIV1;//分频因子timer0initpara.alignedmode=TIMER_COUNTER_EDGE;//边沿对齐timer0initpara.counterdirection=TIMER_COUNTER_UP;//向上计数timer0initpara.period=arr;//自动重新加载值timer0initpara.prescaler=prescaler;//预分频值 if=1时就是72Mhz else=72/(prescaler/2)//timer0initpara.repetitioncounter=;//重复计数器值    timer_init(TIMER1,&timer0initpara);//允许更新中断timer_interrupt_enable(TIMER1,TIMER_INT_UP);//TIMER0中断优先级设置nvic_irq_enable(TIMER1_IRQn,1,1);//抢占优先级，响应优先级//使能TIME0timer_enable(TIMER1);}

②、定时器中断

void TIMER1_IRQHandler(void){if(SET==timer_interrupt_flag_get(TIMER1,TIMER_INT_UP)){gd_led_toggle();}timer_interrupt_flag_clear(TIMER1,TIMER_INT_UP);}
