STM32驱动OLED显示菜单功能（附带oled硬件iic驱动代码）

 

 while循环里面就写菜单退出 菜单进入

} 

int menu2_LED(void)
{
	
	
	OLED_Clear();

			{	
			HAL_UART_Receive_DMA(&huart1,(uint8_t*)rx_buf,3);
			OLED_GotoXY(100,25);

					}break;
				}	
		
			}
			
			else
			{
				HAL_UART_DMAStop(&huart1);
				OLED_Clear();
				HAL_Delay(150);//mo ming qi miao de yan shi, deng dai geng xin flag
				return_FLAG=0;
				return 1;
			
			} 
	
	}

}

这里是选择发送ABC 和接受字符

退出回调函数：

void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)
{
	if(GPIO_Pin==GPIO_PIN_13)
	{
		return_FLAG=1;
		
	}



}

任务三是adc采样 双通道采样 

int menu2_ADC(void)
{
	
	OLED_Clear();
	OLED_GotoXY(5,0);
	OLED_Puts("X:",&Font_16x26,1);
	OLED_GotoXY(5,30);
	OLED_Puts("Y:",&Font_16x26,1);
	OLED_Refresh();
	uint16_t adc_buf[2];
	HAL_ADC_Start_DMA(&hadc1,(uint32_t*)adc_buf,2);
	
	while(1)
	{
		if(!return_FLAG)
		{
			uint8_t Kp_txt1[10];
			sprintf(Kp_txt1,"%.4fV",((float)adc_buf[0]*3.3)/4095);
			OLED_GotoXY(50,5);
			OLED_Puts(Kp_txt1,&Font_11x18,1);
			uint8_t Kp_txt2[10];
			sprintf(Kp_txt2,"%.4fV",((float)adc_buf[1]*3.3)/4095);
			OLED_GotoXY(50,35);
			OLED_Puts(Kp_txt2,&Font_11x18,1);
			OLED_Refresh();
			HAL_Delay(200);
		}
		
		else
		{
			HAL_ADC_Stop_DMA(&hadc1);
			OLED_Clear();
			return_FLAG=0;
			return 0;
		}
		
	}
}

 利用dma采样双通道

HAL_ADC_Start_DMA(&hadc1,(uint32_t*)adc_buf,2);

将32位浮点数转换为8位可展示 

 

 

			uint8_t Kp_txt1[10];
			sprintf(Kp_txt1,"%.4fV",((float)adc_buf[0]*3.3)/4095);

这里就是转换了

下面是oled.c和oled.h文件了 在下章给出
